The invention relates to a mobile strapping apparatus for strapping articles for packing with a strapping band, which strapping apparatus has a tensioning device for applying a band tension to a loop of a strapping band, and has a welding device for producing a welded connection, in particular a friction-welded or vibration-welded connection, on two regions, situated one above the other, of the loop of the strapping band, has a chargeable energy store for storing electrical energy, wherein the electrical energy is provided as drive energy for motor-imparted drive movements of the strapping apparatus, and a housing with a front cover part for the tensioning device, and a rear housing part, which is preferably provided for accommodating the energy store, and a handle for holding the strapping apparatus, which handle is arranged between the front housing part and the rear housing part.
Strapping apparatuses of said type have a tensioning device by means of which an adequately high band tension can be applied to a band loop that has been placed around the respective article for packing. By means, preferably, of a clamping device of the strapping apparatus, it is then possible for the band loop to be fixed to the article for packing for the subsequent connecting process. In the case of generic strapping apparatuses, the connecting process is performed by way of a vibration welding device, in particular by way of a friction welding device. Here, pressure is exerted on the band by means of a friction shoe which moves in oscillating fashion in the region of two ends of the band loop. The pressure and the heat generated by the oscillating movement of sections of the two band sections causes the band, which generally has plastic, to locally melt for a short period of time. This gives rise to a permanent connection, which can be released again at most with high force, between the two band layers.
Generic strapping apparatuses are provided for mobile use, wherein the appliances are intended to be carried by a user to the respective usage location and should generally not be dependent there on the use of externally supplied energy. In the case of known strapping appliances, the energy required for the intended use of such strapping appliances for tensioning a strapping band around articles for packing of any type and for producing a fastening is generally provided by an electric battery or by compressed air. By means of said energy, the band tension introduced into the band by means of the tensioning device is generated, and a fastening is produced on the strapping band. Generic strapping apparatuses, and thus also strapping apparatuses according to the invention, are furthermore provided for connecting only weldable plastics bands to one another.
In the case of mobile appliances, a low weight is of particular importance in order that the user of the strapping apparatus is subjected to the least possible physical burden when using the apparatus. Likewise, for ergonomic reasons, the most uniform possible distribution of the weight over the entire strapping apparatus should be provided, in particular in order to avoid a concentration of the weight in the head region of the strapping apparatus. Such a concentration leads to adverse handling characteristics of the apparatus. Furthermore, the most ergonomic possible and user-friendly handling of the strapping appliance is always sought. In particular, the possibility of incorrect operation and malfunctions should be as low as possible, and information regarding the operating state should be visible to the user of the strapping appliance.
To meet these requirements, it has hitherto been substantially conventional to equip mobile strapping appliances with a handle by which the strapping appliance can be carried and in particular operated during strapping processes. Here, embodiments are conventional in which the handle is arranged between a front and a rear end of the strapping appliance, wherein, at the front end, there is or are situated at least one or more functional units of the strapping appliance, such as the tensioning device for imparting a band tension, the fastening device for connecting the band ends, and the severing device for severing the strap from a band supply. Generally also provided on the front housing region, which entirely or partially covers said functional units, are operating and display elements of the strapping apparatus which are usually in the form of pushbuttons, if appropriate in the form of foil pushbuttons, and in the form of LED displays.
In the case of many already known strapping appliances, in the region of the other end of the handle, i.e. at the rear end of the strapping appliance, there is situated a receptacle for a battery. Even though, with this embodiment of mobile strapping appliances, it is already possible to achieve good handling characteristics and the appliances have an acceptable balanced weight distribution, they cannot be fully satisfactory in particular with regard to ergonomic aspects.
Said arrangement however has the disadvantage that the comprehensive mechanism which is arranged in the front housing region of the strapping apparatus, and which takes up a lot of space, gives rise to considerable restrictions with regard to the selection of the location at which the operating pushbuttons and display means and the associated electronics and cabling can be arranged. In particular, a restriction exists to the effect that the ergonomically best position cannot be achieved without limitation, at least not if the housing is not considerably increased in size in order to provide additional space for said elements.
It is therefore the object of the invention to provide a generic strapping appliance which has improved ergonomic characteristics.
According to the invention, said object is achieved, in the case of a mobile strapping apparatus of the type mentioned in the introduction, in that a display means for displaying operational information of the strapping apparatus is arranged on the rear housing region of the housing of the strapping apparatus. The arrangement of the preferably only one display means for information regarding operating states of the strapping apparatus has the ergonomic advantage that a “top-heaviness” that often exists in the case of such strapping apparatuses can be reduced, as the “display means” assembly and the weight thereof are relocated from the front head region of the strapping apparatus into the rear housing region. Owing to the relocation of the display means, not only is the weight of the front region of the strapping apparatus reduced by the weight of the display means, it is rather even the case that weight is relocated into the rear region of the strapping apparatus, thereby enhancing the reduction of the top-heaviness.
A further advantage arises from the fact that, by way of the measure according to the invention, the risk of damage to the display means is considerably reduced. In the case of an arrangement in the front housing region, such as has hitherto been provided, there is the risk of the display means and the associated electronics being significantly damaged in the event of the mobile strapping apparatus being dropped repeatedly. Owing to the arrangement of the display means in the rear region of the strapping apparatus, which region, owing to the conventional and scarcely avoidable top-heaviness of the apparatus, generally does not strike the ground first in the event of the strapping apparatus being dropped, it is possible for the risk of damage to the sensitive display means to be considerably reduced in relation to conventional arrangements. Owing to the fact that the strapping apparatus generally strikes the ground by way of its top side when dropped, the load in the rear region of the strapping apparatus is thus considerably lower, whereby the risk of damage to the display means is considerably reduced by means of the measure according to the invention.
Furthermore, by means of the arrangement according to the invention, the assembly of strapping apparatuses according to the invention can be simplified, because both the one or more display means, including the electronics that may be required for the same, and the control circuit board of the apparatus controller and the terminals for the battery can be arranged in the immediate vicinity of one another on the rear housing region of the strapping apparatus. It is firstly possible for said components to be formed as an assembly, which can be installed with little effort and which, in the event of repairs, can also be removed and replaced with similarly little effort. Secondly, the laying of relatively long cables in the strapping apparatus, such as has hitherto been required for the cabling of said components, can be dispensed with. This reduces both the outlay in terms of construction and the outlay in terms of assembly for strapping apparatuses according to the invention. Furthermore, this also makes the assembly process easier, because, by contrast to the arrangement in the front housing region, the display means in the rear housing region cannot come into conflict with the mechanism of the strapping apparatus. Furthermore, the display means can be arranged in the rear housing region at practically any desired, ergonomically expedient location, because here, the mechanism of the strapping apparatus generally does not need to be taken into consideration.
The display means may be situated at basically any desired location on the rear housing region, and thus behind the handle. Said display means may in particular be arranged on one side of the rear housing region. It is however particularly preferable for the display means to be arranged on a top side of the rear housing region. Thus, the display means is fitted on the strapping apparatus in an ergonomically particularly expedient manner, and can be viewed by the user at any time, even during use for the production of strapping on articles for packaging. In this context, the top side of the rear housing region can be regarded as being the surface that can be seen or read in a plan view of the strapping apparatus. The surface may in this case be a horizontally oriented surface, one or more surfaces that are inclined relative to a horizontal plane, or one or more surfaces provided with one or more curvatures.
The display means may advantageously be in the form of a combined operating and display panel. This may in particular extend over a certain area of the rear housing region, in which region information is displayed and the inputting of settings and/or the triggering of particular processes may be performed by way of corresponding input means arranged there. The operating and display panel may in particular be in the form of an LCD display screen in combination with pushbuttons which may be fixedly predefined in terms of their position, and which are preferably collectively arranged within a certain sub-area of the rear housing region. Using at least one of the pushbuttons, it is possible to navigate in a menu displayed on the display means, to perform inputs, and to select and, if appropriate, trigger functions or working steps of the strapping apparatus.
In one of several different possible solutions according to the invention that are preferred in this regard, the operating and display panel may also comprise, and be collectively formed as, a touchscreen. Said touchscreen may extend over a certain, in particular continuous, area, on which area different items of information and different operating and/or input elements can be at least temporarily displayed. Here, operating elements may be understood to mean area elements of the touchscreen, the touching of which causes functions of the strapping apparatus to be directly or indirectly triggered. Input elements may be understood to mean area elements by way of which inputs, for example value inputs, or settings, such as for example “on/off” or “large/small” or any other required input, can be made. In the context of the invention, a touchscreen may therefore be understood to mean an input and display device, in the case of which, by touching a predeterminable area region of said device, inputs can be made which either generate inputs for the control of the strapping apparatus and/or trigger functions of the strapping apparatus. The inputs may be made in particular by way of a touch action using a finger.
A touchscreen, in the case of which, by contrast to foil keypads, for example, the functions of particular areas can be changed either in a predetermined manner or by programming, it is also possible for particular area regions to be provided successively with different functions. This permits particularly expedient and effective use of the available area, and particularly easy retroactive addition of further functions and/or setting options. The latter may be realized for example through the installation of software updates into the controller of the strapping apparatus.
According to a further embodiment, the mobile strapping apparatus is equipped with a structural unit which comprises the display and operating device and the controller, at least parts thereof, of the strapping apparatus. The structural unit may preferably be equipped with all of the electronics of the strapping apparatus. Since a structural unit of said type can be preassembled, the installation of the display and operating device and of the controller into the strapping apparatus is possible particularly easily and quickly. A further significant advantage arises from the fact that, in the event of a defect, the defective structural unit can be exchanged for a new structural unit quickly and with little effort. Since the structural unit is preferably arranged in the rear housing region, the strapping apparatus mechanism which is arranged preferably in the front housing region does not pose an obstruction even during such maintenance processes.
Further preferred refinements of the invention will emerge from the claims, from the description and from the drawings.
The invention will be discussed in more detail on the basis of exemplary embodiments which are illustrated purely schematically in the figures, in which:
One embodiment of the manually actuatable mobile strapping appliance 1 (strapping apparatus) shown in
By means of the strapping appliance 1, a loop (not illustrated in any more detail in
Subsequently, at a point of the band loop at which two layers of the band 10 lie one above the other, welding of the two layers can be performed by means of the fastening device, which is formed as a friction welding device 13 of the strapping appliance. The band loop can hereby be permanently closed. For this purpose, the friction welding device 13 is equipped with a welding shoe 11 which, by way of mechanical pressure on the strapping band and a simultaneous oscillating movement with a predetermined frequency, causes the two layers of the strapping band 10 to melt. The plasticized or molten regions of the two band layers flow into one another and, after the band 10 cools, a connection between the two band layers then forms during a cooling period. If necessary, the band loop may then simultaneously be severed from a supply roll (not illustrated) of the band 10 by means of a severing device 12 of the strapping appliance 1. Subsequently, the strapping appliance 1 can be removed from the article for packing and from the band strap produced.
The actuation of the tensioning device 6, the advancement of the friction welding device 13 by means of a transfer device of the friction welding device 13, and also the use of the friction welding device per se, and the actuation of the cutting device, are performed using only one common electric motor 14, which provides a respective drive movement for these components. The structural solution provided for this purpose may correspond to that described in WO2009/129634 A1, the content of disclosure of which is hereby incorporated by reference. For the supply of electricity, an exchangeable battery 15, which can in particular be removed in order to be charged, is arranged on the strapping appliance. A supply of other external auxiliary energy, such as for example compressed air or further electricity, is duly not provided in the case of the preferred strapping appliance as per
In the present case, the portable, mobile strapping appliance 1 has an actuation element 16, configured as a press switch, which is provided for setting the motor in operation and which will hereinafter be referred to as tensioning pushbutton. For the actuation element 16, it is possible to set three modes by means of a mode switch 17 (
During the formation of a fastening, after the band has been placed, in the form of a loop, around the article for packing, is guided here in a predetermined manner in one layer through the tensioning device 6 and in two layers through the fastening device. In other embodiments of the invention, it may also be provided that the strapping band is arranged in two layers between the tensioning wheel and the tensioning plate—or some other counter support which interacts with the tensioning wheel—for the tensioning process. The intended band tension is imparted by engagement of the tensioning device 6 into the upper layer, guided through the tensioning device 6, of the band and by way of a pulling-back movement of the band. Thereafter, the welding shoe 11 is lowered in the direction of a counter support surface 22 of the base plate 4. Depending on the activated operating mode of the strapping appliance 1, this takes place automatically following the completion of the tensioning process or as a result of separate triggering of the friction welding process by actuation of the pushbutton provided for the purpose. During the friction welding process, the band remains clamped between the tensioning wheel 7 and the tensioning counter support 23, and is held there during the formation of a fastening. During this method step of forming the strapping, the tensioning device has the function of a band clamp or of a clamping device which, by way of two interacting clamping elements, clamps the band between them. As a result of the lowering of the welding shoe 11, the two band layers that have been guided through the fastening device are pressed against one another and against the counter support surface 22.
In the fastening device, the band is arranged in two layers, wherein the lower band layer lies with its lower band surface against the inclined counter support surface 22 and is pressed against the latter. With the upper surface, the lower band layer lies against the lower surface of the upper band layer. The welding shoe 11 presses against the upper surface of the upper band layer. In said position of the band, the friction welding device 13 commences the formation of a fastening by way of the oscillating movement of the welding shoe 11 transversely with respect to the longitudinal profile of the band. In this way, the two band layers bearing against one another are melted. The materials of the band layers flow into one another and form a cohesive connection during the subsequent cooling process when the oscillating movement of the welding shoe has been stopped. Subsequently, the welding shoe 11 is moved away from the counter support surface 22 and the tensioning device 6 is removed from the band, whereby the clamping action is eliminated, and the two band layers are released.
The strapping appliance according to the invention is equipped with the operating and display panel 25, which may also be in the form of a touchscreen. The touchscreen may be a resistive or capacitive touch-sensitive areal screen (display), wherein other forms of touchscreen could also be used. In the exemplary embodiment, the touchscreen has a substantially rectangular display and operating surface 25a. Such touchscreens are marketed for example by the company Ad Metro, 1181 Parisien Street, Ottawa, Ontario, Canada K1B 4W4, which can be sourced in Germany from the company Interelectronix e.K., Ottostrasse 1, 85649 Hofolding.
In other embodiments, the display and operating device may also have conventional switch pushbuttons or other operating elements, in particular foil pushbuttons and other pushbuttons in the case of which the position of the pushbutton is fixedly and invariantly predefined, and a mechanical change in the switching state of said switching pushbutton is effected not just by touch but (also) by pressure. In such alternative embodiments, information regarding the state of the strapping apparatus may likewise be performed by way of conventional display devices without operating elements integrated into the display area, such as for example by way of LCD or TFT displays.
Even though the illustrations of
On the display and operating panel 25a, it is possible for different items of information and touch-sensitive actuation or input elements to be displayed alternately or simultaneously. It is possible for different display and input levels to be provided, which can be selected and deselected and in which in each case different items of information and actuation and input elements can be displayed. The displayed elements may in particular provide information regarding the state and settings of the strapping appliance and of its components. As actuation elements, it is possible in particular for multiple pushbuttons 17 to 19, which can be triggered by touch, to be displayed. With said pushbuttons, it is possible to preselect and set the above-described different modes of manual (MAN), semi-automatic (SEM) and automatic (AUTO) of the strapping appliance, and parameters of the strapping processes. Settable and displayed parameters may for example be the tensioning force, the welding time and the cooling time. The setting may be performed by adding or subtracting predefined steps of the respective value by actuating the plus or minus pushbuttons 18, 19, and by confirming the value to be set by means of the mode switch 17, which in this case functions as a confirmation pushbutton. By actuation of the mode switch 17, the set value is stored in the controller in order to be utilized during the subsequent strapping process. Likewise, the band type used may be displayed and selected by selecting from a predefined list of band types 26. Furthermore, present operating states may be displayed, such as for example the state of discharge 27 of the battery and, during the tensioning process, by way of a progress bar 28, the tensioning force already attained as a fraction of the set tensioning force to be attained.
The values preset in this way are displayed by the strapping appliance on the display panel 32 and are utilized during strapping processes until the parameter values are changed again. The strapping processes themselves are triggered or started by way of the tensioning pushbutton 16, as a further actuation element, which is arranged in an ergonomically expedient manner in the region of the front end of the handle of the strapping appliance 1. To be able to place the band into the tensioning device, a rocker pushbutton 20 is arranged below the tensioning pushbutton 16, which rocker pushbutton may for example, and preferably, be in the form of a press button. By pressing the rocker pushbutton 20, the rocker 8 is opened, that is to say the rocker is pivoted with its tensioning plate 23 away from the tensioning wheel 7, such that a gap is formed between the tensioning plate 23 and the tensioning wheel 7. For as long as the rocker pushbutton 20 remains depressed, the tensioning plate 23 of the rocker is arranged with a spacing to the tensioning wheel 7, such that the band can be placed into the tensioning device between the tensioning plate 23 and the tensioning wheel 7. When the rocker pushbutton 20 is released, the rocker 8 pivots with the tensioning plate 23 in the direction of the tensioning wheel 7, whereby the tensioning plate 23 bears against the underside of the band, and the top side of the band bears against the tensioning wheel 7.
If the strapping appliance 1 is held by the handle 3, the tensioning pushbutton 16 can be actuated using the thumb of the hand that is holding the handle 3. The rocker pushbutton 20, which is arranged on the underside of the handle 3, can in this case be actuated in an ergonomically expedient manner by way of the index finger, without an adjustment of grip being necessary for this purpose. In other embodiments according to the invention, the rocker pushbutton 20 may also be arranged on the top side of the strapping appliance, in particular in the direct vicinity of the tensioning pushbutton 16, such that both the tensioning pushbutton 16 and the rocker pushbutton 20 can be actuated using the thumb of the hand that is gripping the handle 3. Here, the tensioning pushbutton 16 may be responsible for triggering both the tensioning process and the welding process, wherein, by setting the corresponding mode, it may be provided that a single press of the tensioning pushbutton triggers both the tensioning process and the subsequent connecting process. By selecting a different operating mode, it is also possible for only the tensioning process to be initiated by way of a single press of the tensioning pushbutton. To carry out the connecting or welding process, it is then necessary for the tensioning pushbutton to be pressed once again.
In an alternative embodiment to this, it is also possible for (only) one combination pushbutton to be provided on the strapping appliance, in particular in the region of the handle, which combination pushbutton has two actuation regions, one for the tensioning and welding, and one for the rocker actuation. In this case, too, it is optionally possible here for the tensioning and welding process to be triggered by way of only one actuation, or by way of mutually separate actuation processes, of one actuation region. The tensioning process may be triggered by way of a single actuation, and the connecting process may be triggered by way of a multiple actuation following the tensioning process, in particular by way of a double-click. The other actuation region is provided for the rocker actuation. Such a combination pushbutton may be situated for example at least approximately at that location on the strapping appliance at which the tensioning pushbutton 16 is arranged in
In a further alternative embodiment, it is possible, in particular in the region of the handle 3, for a dedicated pushbutton to be provided for each of the three functions. In this case, to trigger the respective process, it may be provided that only a single actuation of the respective pushbutton is required in each case.
In all embodiments, it is preferable if the pushbuttons assigned to the tensioning process and to the welding process trigger electrical switching processes which are supplied to the controller. By contrast, the actuation of the rocker pushbutton may preferably be electromechanically transmitted to the rocker and trigger a pivoting process of the rocker. It is likewise possible for one or more additional drive elements to be provided which trigger and perform the pivoting process of the rocker and which are electrically actuated.
All refinements of the described operating concepts may also be of independent significance and constitute independent inventions.
As illustrated in particular in
Likewise, it is now possible, according to the preferred refinement of the invention illustrated in
An electrical contact for the supply of electricity and for data transfer between the strapping appliance and the assembly 29 may be provided by way of one or more electrical plug connections 30, 31, 32. In the exemplary embodiment, for this purpose, four detachable plug connections 30, 31, 32 are provided; in other embodiments of the invention, a number of electrical plug connections that differs from this may also be provided. For this purpose, the housing preferably has, in the region of the board, plug connectors 30b, 31b, 32b which are detachably connectable to corresponding plug connector counterparts 30a, 31a, 32a of the board of the control/power printed circuit board 44. The board or the structural unit 29 can be pushed by way of its plug connectors 30b, 31b, 32b onto the plug connector counterparts 30a, 31a, 32a that are fastened to the housing. Here, one of the plug connections 30 serves for the supply of electricity to the motor, and the second plug connection 32 serves for the transmission of signals generated by sensors of the motor, in particular by Hall sensors. The third plug connection 31 is provided for the transmission of signals from sensors which are situated in the region of the mechanism of the strapping appliance, in particular in the region of the tensioning device and/or of the connecting device and of their respective drive trains. A fourth plug connection may serve for the transmission of signals of pushbuttons which trigger particular functions, in particular the tensioning pushbutton 16 and the rocker pushbutton 20. In other preferred embodiments, signals from different components of the strapping apparatus may also be transmitted via one or more plug connections.
Provided on the housing directly below the structural unit 29 is a receptacle 59 for the battery 15, into which receptacle the battery 15 can be pushed from the rear of the housing and arranged securely by means of a releasable snap-action connection. Within the recess 59 there are provided further electrical contacts of the strapping appliance for the connection of the battery, for example a contact plate.
From the contact plate, which is not visible in detail in the illustration of
The housing 2 of the strapping appliances 1 illustrated in the figures have the front region and the rear region, between which there is situated a central housing region 38 with a handle 3. In the two preferred exemplary embodiments according to the invention illustrated here, the front region and the rear region 36, 37 of the housing 2 are connected to one another by way of the handle 3. In these exemplary embodiments and in other exemplary embodiments, the housing may have two interconnected shells, and may preferably be composed of plastics shells of said type. The parting line or the parting plane at which the two shell halves are joined to one another and are connected to one another by suitable fastening means, such as for example screws, may preferably extend over the entire length of the strapping appliance, and may also run through the handle 3 over the entire length thereof.
The front region 36 of the housing 2 surrounds the tensioning, friction welding and severing device in such a way that the housing 2 exposes, or does not cover, only those mechanical components of the strapping appliance which a user should have access to, in particular parts which are provided for engaging into the two band layers during the strapping process. On one side of the front region 36 of the housing 2 there is provided an opening which can be detachably closed by way of a cover 63 and which can be utilized for maintenance purposes, for example for the exchange of wear parts.
At least in the exemplary embodiments of
The handle 3, which is arranged substantially in the region of the top side of the strapping appliance, merges by way of its front end 3a into the front region of the housing, in particular into the top side of the front housing region 36. As seen in the opposite viewing direction, it is thus the case that the front housing region 36 merges into the handle 3. The rear end 3b of the handle 3 merges into the rear region 37 of the housing 2, in particular into the top side 37a of the rear housing region 37. In the preferred exemplary embodiment, in each case one half of the handle 3 belongs to one housing shell, and the other half of the handle belongs to the other housing shell. The respective half of the handle is connected in unipartite fashion to, or is integrated into, the respective housing shell.
The strapping appliance 1 has, in particular in the region of the tensioning device 6 and of the fastening or friction welding device 13, band-guiding means such as are known per se, by which band guiding means an at least substantially predetermined profile of the strapping band 10 in the strapping appliance, in particular of the band section between the tensioning device and the welding device 13, is realized. Said profile, in particular a centerline 10a, which at least in the plan view is in the form of a straight line, of a top side of the band 10 will hereinafter be provided as a reference line and definition aid for the orientation of the handle 3. In said plan view, said band orientation runs along a straight line.
If the transition regions of the handle 3 into the front housing region 36 and into the rear housing region 37 are connected to one another by a straight line 40, said straight line 40 runs non-parallel with respect to the centerline 10a of the band profile in the strapping appliance 1. Transition regions can be regarded as being the points at which, in each case, the profile of the surfaces of the top sides of the front and rear housing regions 36, 37 changes in order to transition here into the handle in each case. Alternatively, (front and rear) transition regions may also be understood as meaning the ends of the handle up to which it is possible for the handle to be entirely or at least partially gripped using the operating hand. Said transitions may be of continuous or discontinuous form. The two points 41, 42 of the transition regions that are utilized for forming the imaginary straight line 40 may, with respect to a plan view, be situated in the center of the respective width of the handle 3. With respect to the straight line 10a arising from the band profile, the two points 41, 42 have different spacings 62, 62 to the straight line 10a, and are thus offset with respect to one another in the direction of the band profile. With respect to a plan view of the strapping appliance, and with respect to the band profile in the strapping appliance that arises from the arrangement of the band, the straight lines 10a, 40 run non-parallel with respect to one another, and enclose a non-0° angle φ.
The angle φ is furthermore distinguished by the fact that the straight line 40 that defines it runs, with respect to the plan view and with respect to the band 10 and its centerline 10a, on the other side 31 of the centerline 10a in relation to the insertion side 32 from which the band is inserted into the strapping appliance. The handle 3 is thus, with respect to the band 10, situated on the other side 31 in relation to the insertion side 32. In the preferred embodiment of the invention in the illustration of
In preferred embodiments of the invention, said angle φ may be selected in particular from a range of 3° to 89°, particularly preferably from a range of 5° to 70°, and more preferably from a range of 7° to 35°. It is the intention here for each individual angle value from the above-stated angle ranges to be explicitly disclosed. An explicit listing of each individual angle value is omitted merely owing to a lack of practicability. As can be seen in particular in the lower plan-view illustration of
The two substantially rectilinearly oriented sections of the handle enclose an angle of approximately 160° in the exemplary embodiment. Here, the orientation of the two sections 64, 65 is such that its centerline 64a, which corresponds to the longitudinal profile of the front section of the handle, encloses, with the centerline 10a of the band, the angle φ by which the handle is, with respect to a plan view, at least regionally inclined with respect to the band. The longitudinal profile of the rear section 65 itself, that is to say in particular the centerline 65a thereof, is by contrast oriented substantially parallel to the band section, situated opposite the handle, of the strapping band. This configuration of the handle 3 gives rise to an ergonomically expedient enlarged spacing between the strapping band and the operating hand that is holding the strapping appliance.
