Patent Application
20070017622
The present invention relates to an apparatus for making cloth articles of manufacture and the like.
More specifically, the present invention relates to an electromechanic apparatus designed for cutting to a desired shape and simultaneously hemming, by an adhesive textile applied element, a fabric material tubular element.
Is already known in the prior art to make knitted articles of manufacture starting from a tubular knitted element which is cut and hemmed by applying an adhesive fabric strip thereto.
Conventional cutting and hemming operations on said tubular element were performed as separate operating steps, either manually or by a machine for applying an adhesive strip to the tubular element.
The aim of the present invention is to provide such an apparatus which allows to make the desired cloth or fabric articles of manufacture in a much more quick and efficient manner than prior like articles of manufacture making systems.
Within the scope of the above mentioned aim, a main object of the invention is to provide such an apparatus which is adapted to cut and hem a tubular element by substantially simultaneous cutting and hemming operations.
Another object of the present invention is to provide such an apparatus allowing to finishing the fabric material edge, independently from its type, without using seaming operations.
Another object of the present invention is to provide such an apparatus allowing the articles of manufacture to be finished without altering the resilient characteristics of their fabric materials and additional applied materials.
Yet another object of the present invention is to provide such an apparatus allowing to carry out finishing operations on said articles of manufacture by means of hemming, edging and flat application operations, to allow a textile fabric material to always contact the skin of a user, that is preventing the user skin from being contacted by a plastics material.
Yet another object of the present invention is to provide such an apparatus for making cloth articles of manufacture and the like which, owing to its specifically designed features, is reliable and safe in operation.
According to one aspect of the present invention, the above mentioned aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by an apparatus for making cloth articles of manufacture and the like, characterized in that said apparatus comprises a bearing framework defining a working region where a fabric material tubular element is arranged, and comprising cutting means for cutting said tubular element to provide said tubular element with a cut through edge, and hemming means for applying an adhesive strip to said cut edge of said tubular element.
Further characteristics and advantages of the present invention will become more apparent hereinafter from the following detailed disclosure of a preferred, though not exclusive, embodiment of the invention which is illustrated, by way of an indicative, but not limitative, example in the accompanying drawings, where:
With reference to the number references of the above mentioned figures, the apparatus according to the invention, which has been generally indicated by the reference number 1, comprises a bearing framework 2, thereon a working region 7 is defined, said working region comprising a fabric material hemming means, including a guide element 3 for an adhesive strip, generally indicated by the reference number 4, which adhesive strip is delivered or fed, by a strip feeding assembly, from an adhesive strip delivery bobbin or roll.
The hemming device proper 3 is arranged, with an outlet end thereof, at a top wheel 5 and a bottom wheel 6, therebetween a textile fabric material, generally indicated by the letter T, which must be performed to finishing steps, is caused to pass.
More specifically, said wheels 5 and 6 are coupled through driving motors.
According to the present invention, the working region 7, comprises, upstream of the hemming means, cutting means comprising at least two cutting blades or knives 8 and 8a, designed for cutting through the textile fabric material T according to a preset cutting plane.
To that end, the fabric material T comprises suitable marking means for marking a cutting line, designed for allowing an operator to guide said fabric material to allow the cutting blade 8 to follow the preset cutting line.
The above disclosed apparatus or machine can carry out several types of operating steps.
In particular, the apparatus is adapted to perform a hemming operation, by using a strip which can comprise a single-adhesive fabric strip 4 to be folded to provide a sort of bridge of the fabric material T, thereby correspondingly cover the edge portions, as is clearly shown in
The hemming operation can also be performed by a single-adhesive casing tape element.
For performing the hemming operation, the fabric material T is folded at an edge portion thereof and is supplied a strip including a biadhesive film or a biadhesive resilient element.
For flatly applying the strip, it is possible to apply to the textile fabric material T a monoadhesive film or, optionally, a monoadhesive fabric.
To provide a proper heating, the apparatus further comprises a heating region 10 including heating means 9.
It has been found that the invention fully achieves the above mentioned aim and objects.
In fact, the invention provides an electropneumatic apparatus for cutting to a desired shape and simultaneously hem the cut fabric material by using an adhesive textile auxiliary strip element.
The apparatus according to the present invention is also designed for performing cutting and hemming operations on fabric pieces made on a circular seamless loom.
The apparatus, moreover, comprises adjusting means for adjusting the height of the processing plane thereof, and the working station can be slanted according to any desired inclination.
Moreover, the apparatus further comprises a fitting drawer, a driving system and two wheels which are actuated or driven with independent speeds (a differential effect) by a sequential change gear, and a trimming device for trimming away the exceeding fabric portion before the hemming operation proper: moreover, the subject apparatus also provides to perform a variable frequency cutting operation.
Moreover, the bottom and top heating devices for heating the adhesive material provide independent adjustments of the adhesive melting temperature.
The heat amount can be automatically changed depending on the fabric material feeding speed.
Moreover, the apparatus can also comprise cooling means for properly cooling the outlet adhesived edge of the fabric.
The top wheel can swing with an adjustable pressure and an electronic apparatus is furthermore provided for controlling and sequentially programming the tension of the elastic elements.
Furthermore, the apparatus comprises a programmable logic programming device which can be coupled to the system network to receive and transmit data in real time, as well as illuminating means for illuminating the bottom of the cutting region, suction means for sucking away the waste materials, and further control and programming means for controlling the adhesive strip feeding devices.
The adhesive material applied to the adhesive strip can comprise either one or more continuous adhesive layers or can be applied according to a point by point pattern, thereby providing a grid-like adhesive pattern.
Finally, the apparatus according to the present invention is designed for receiving a broad range of fittings for performing a lot of different types of processing operations.
In practicing the invention, the used materials, as well as the contingent size and shapes can be any, according to requirements and the status of the art.
