Patent Application
20230365372
Generally, an adhesive tape is applied to various surfaces, such as on automotive parts where a two-tone paint scheme is desired. Further, a tape applicator is used to hold an adhesive tape spool and feed the adhesive tape to the surface on which the adhesive tape is to be applied. The tape applicator can include a cutting arrangement that allows cutting of the adhesive tape. The cutting arrangement includes a blade that contacts and cuts the adhesive tape.
Conventional tape applicators and their cutting arrangements fail to cut the adhesive tape efficiently, especially when low unwind adhesive peel strength and high elastic elongation adhesive tapes are used. These tapes are frequently used for two-tone paint masking where easy removal from the workpiece is necessary to not damage the underlying base paint layer. In some cases, due to low unwind forces and high adhesive tape elongation, the adhesive tape gets pushed into a gap in the tape guide without cutting the adhesive tape, which is not desirable. This happens since there is not much tension on the tape from the low unwind peel forces and low force needed to elongate the adhesive tape. More particularly, for adhesive tapes having a machine direction (MD) elongation at yield strength, such as greater than 250%, 500% or even 1000% MD elongation, conventional cutting arrangements may only crinkle the adhesive tape rather than severing the adhesive tape.
Hence, there is a need of a tape applicator that cuts the adhesive tape efficiently, and also allows operators to apply adhesive tapes quickly and accurately.
A tape applicator for an adhesive tape includes an integrated cutting arrangement for cutting the adhesive tape while switching from one work surface to another. The tape applicator includes a cutting blade. In one embodiment, the cutting blade is angularly disposed relative to a cutting head, such that the cutting blade provides improved cutting action of low unwind and high elongation adhesive tapes. In another embodiment, the cutting arrangement allows nipping of the adhesive tape which improves tension on the adhesive tape having low unwind forces and high elongation, thereby allowing efficient cutting of the adhesive tape. The tape applicator includes a push button which may be actuated to cut the adhesive tape at a desired location. The tape applicator described in this disclosure allows operators to apply adhesive tapes quickly and accurately to complex work surfaces, such as automotive parts where there is a two-tone paint scheme.
In an aspect of the present disclosure, a tape applicator for an adhesive tape is provided. The tape applicator includes a cutting head. The cutting head includes a base surface and a cutting blade extending from the base surface, the cutting blade having a blade base where the cutting blade intersects with and extends from the base surface, and the cutting blade having a cutting edge disposed above the base surface. The tape applicator also includes a pinching head including a first pinching projection and a second pinching projection separated by a blade slot. The tape applicator further includes a Y-axis extending from a midpoint of the blade base and extending orthogonal to the base surface, a longitudinal blade axis extending from the midpoint to a center point of the cutting edge, and a first angle greater than 0 degrees between the Y-axis and the longitudinal blade axis. The tape applicator includes a Z-axis tangent to the base surface, passing through the midpoint, and parallel to the blade base, a cutting edge axis passing through the center point and tangent to the cutting edge, and a second angle less than 80 degrees between the Z-axis and the cutting edge axis. The tape applicator also includes an adhesive tape spool unwind for dispensing the adhesive tape, wherein at least one of the cutting head and the pinching head is movable from a first position with the cutting blade disposed outside of the blade slot to a second position with the cutting blade disposed at least partially within the blade slot.
In another aspect of the present disclosure, a tape applicator assembly is provided. The tape applicator assembly includes an adhesive tape. The tape applicator assembly also includes an adhesive tape spool unwind for dispensing the adhesive tape.

The tape applicator assembly includes a cutting head including a base surface and a cutting blade extending from the base surface, the cutting blade having a blade base where the cutting blade intersects with and extends from the base surface, and the cutting blade having a cutting edge disposed above the base surface. The tape applicator also includes a pinching head including a first pinching projection and a second pinching projection separated by a blade slot. The tape applicator further includes a Y-axis extending from a midpoint of the blade base and extending orthogonal to the base surface, a longitudinal blade axis extending from the midpoint to a center point of the cutting edge, and a first angle greater than 0 degrees between the Y-axis and the longitudinal blade axis. The tape applicator includes a Z-axis tangent to the base surface, passing through the midpoint, and parallel to the blade base, a cutting edge axis passing through the center point and tangent to the cutting edge, and a second angle less than 80 degrees between the Z-axis and the cutting edge axis. The tape applicator also includes an adhesive tape spool unwind for dispensing the adhesive tape, wherein at least one of the cutting head and the pinching head is movable from a first position with the cutting blade disposed outside of the blade slot to a second position with the cutting blade disposed at least partially within the blade slot.
In yet another aspect of the present disclosure, a method of using a tape applicator for applying an adhesive tape to a work surface is provided. The method includes placing the tape applicator on the work surface. The tape applicator includes a cutting head comprising a base surface and a cutting blade extending from the base surface, the cutting blade having a blade base where the cutting blade intersects with and extends from the base surface, and the cutting blade having a cutting edge disposed above the base surface; a pinching head comprising a first pinching projection and a second pinching projection separated by a blade slot; a Y-axis extending from a midpoint of the blade base and extending orthogonal to the base surface, a longitudinal blade axis extending from the midpoint to a center point of the cutting edge, and a first angle greater than 0 degrees between the Y-axis and the longitudinal blade axis; and a Z-axis tangent to the base surface, passing through the midpoint, and parallel to the blade base, a cutting edge axis passing through the center point and tangent to the cutting edge, and a second angle less than 80 degrees between the Z-axis and the cutting edge axis.

The present disclosure relates to a hand-held tape applicator assembly 100 for an adhesive tape 102. As illustrated in
Referring to
The tape applicator 116 also includes a handle 124. The handle 124 has a cylindrical shape and includes a stepped design. The handle 124 is coupled to the handle block 120 and the frame 118. In one example, the handle 124 may be bolted to the handle block 120 and the frame 118. In other examples, the handle 124 may be integral with the frame 118. In the illustrated example, the tape applicator 116 includes only one handle 124 to grasp and guide the tape applicator 116 along the work surface 104. In other examples, the tape applicator 116 may include more than one handle coupled to the handle block 120 and the frame 118. In such examples, the handles may be bolted to either side of the frame 118 forming a generally “V-shaped” structure for grasping with both hands. It should be noted that the design of the handle 124 described herein is exemplary, and the handle 124 may include any other shape or design generally known in the art.
The tape applicator assembly 100 also includes a tape guide wheel 130 disposed between the unwind 122 and a cutting section 131 in a direction “D1” of the adhesive tape travel. The cutting section 131 mentioned herein includes a cutting head 156 (shown in
Further, the tape applicator 116 includes a first support bracket 126 that is coupled to the frame 118. The first support bracket 126 define a pair of thumb resting surfaces 128 which may improve ergonomics of the tape applicator 116 and provide convenient handling of the tape applicator 116. The tape applicator 116 also includes a second support bracket 136. The second support bracket 136 is coupled to the first support bracket 126 and the frame 118. In an example, the second support bracket 136 may be coupled to the first support bracket 126 and the frame 118 using mechanical fasteners (not shown), such as bolts or screws.
The tape applicator 116 also includes a turning board 134 located after the cutting section 131 in the direction “D1” of the adhesive tape travel. The turning board 134 is disposed in the adhesive tape path 132, such that the cutting head 156 is disposed between the tape guide wheel 130 and the turning board 134 in the adhesive tape path 132. The turning board 134 changes a direction of the adhesive tape 102 in the adhesive tape path 132 to properly align the adhesive tape 102 with the work surface 104. The turning board 134 is coupled to the second support bracket 136. Further, the turning board 134 is also coupled to the second support bracket 136 using mechanical fasteners (not shown), such as bolts or screws. The turning board 134 includes a first turning surface 138, a second turning surface 140, and a vertical surface 142 extending between the first and second turning surfaces 138, 140. It should be noted that the turning board 134 includes two turning surfaces 138, 140 since the tape applicator 116 is designed to be reversibly used. The turning surfaces 138, 140 are rounded for less drag and adhesive tape 102 damage. The first turning surface 138 contacts the non-adhesive side 114 of the adhesive tape 102 for changing the direction of the adhesive tape 102. In an example, the first and second turning surfaces 138, 140 are angled at approximately 45 degrees relative to the vertical surface 142. In the illustrated example, the turning board 134 changes the direction of the adhesive tape 102 by approximately 90 degrees. In other examples, the turning board 134 may change the direction of the adhesive tape 102 by any other angle, as per requirements.
The tape applicator 116 also includes at least one first magnet 144 coupled to the turning board 134. In the illustrated embodiment, the tape applicator 116 includes one first magnet 144, however, the tape applicator 116 may include two or more first magnets 144. The first magnet 144 facilitates attraction of the tape applicator 116 towards the second surface 108 (see
As illustrated in
Further, the tape applicator 116 includes at least one second magnet 154 disposed proximate the pair of guide rollers 146. The second magnets 154 are received within the hollow space of the housing 148. In the illustrated embodiment, the tape applicator 116 includes a pair of second magnets 154. In other embodiment, the tape applicator 116 may have one second magnet 154 or more than two second magnets 154. The second magnets 154 facilitate attraction of the tape applicator 116 towards the first surface 106 of the work surface 104 along a direction “D2”. The direction “D2” is orthogonal to the direction “D3”. This arrangement provides an attractive force which helps to maintain a firm contact of the tape applicator 116 with the work surface 104.
Further, the turning board 134 also includes a pressure pad 155. The pressure pad 155 contacts the non-adhesive side 114 of the adhesive tape 102 when applying the adhesive tape 102 to the work surface 104. The pressure pad 155 applies a force on the adhesive tape 102 thereby helping to secure the adhesive tape 102 to the work surface 104. The pressure pad 155 may also assist with smoothing out possible wrinkles and/or air bubbles depending on a width of the adhesive tape 102. The pressure pad 155 is generally embodied as a rectangular shaped pad. Alternatively, the pressure pad 155 may have any other shape. A material of the pressure pad 155 may include elastomeric materials, foam materials, bristle brushes, and the like, without any limitations. Referring now to
The cutting head 156 also includes a first portion 162 and a second portion 164 (shown in
The first and second portions 162, 164 extend along a height “H” that is defined between the base surface 158 and the corresponding first and second contact surfaces 165, 167. The height “H” of the first and second portions 162, 164 is greater than a height “H1”, “H2” (shown in
Further, the cutting blade 160 is used to cut the adhesive tape 102 received from the tape guide wheel 130 and moving in the direction “D1”. The cutting blade 160 is coupled to the cutting head 156 such that a portion of the cutting blade 160 is disposed above the base surface 158 and remaining portion of the cutting blade 160 is disposed within the cutting head 156. The cutting head 156 defines an elongated slot 166 such that the slot 166 partially receives the cutting blade 160. A thickness of the slot 166 creates an interference with a thickness “T” (shown in
The cutting blade 160 is embodied as a standard breakaway utility blade herein. The cutting blade 160 is typically made from a hard and tough material to easily sever the adhesive tape 102. In an example, the cutting blade 160 may be made of a metal or an alloy. In one specific example, the cutting blade 160 may be made of stainless steel. It should be noted that a design of the cutting blade 160 described herein is exemplary in nature, and the cutting blade 160 may include any other shape and/or design.
The cutting blade 160 includes a first end 168 and a second end 170. Further, the cutting blade 160 includes a length “L” that is defined between the first and second ends 168, 170. The cutting blade 160 includes a pair of side portions 172 and a base portion 174. The side portions 172 of the cutting blade 160 have a tapering profile such that the thickness “T” (shown in
Further, the cutting blade 160 has a blade base 176 where the cutting blade 160 intersects with and extends from the base surface 158. The blade base 176 defines a midpoint 178. An X-axis of the tape applicator 116 passes through the midpoint 178 and may be parallel to the blade base 176, such that the X-axis generally extends along the direction “D1” past the cutting head 156. Further, the tape applicator 116 includes a Y-axis extending from the midpoint 178 of the blade base 176 and extending orthogonal to the base surface 158. The tape applicator 116 also defines a Z-axis (shown in
The cutting blade 160 has a cutting edge 180 disposed above the base surface 158. The cutting edge 180 is formed at an intersection of the pair of side portions 172. The cutting edge 180 defines a center point 182. In some examples, the cutting edge 180 may include serrations. Further, the cutting blade 160 defines the first height “H1” between the blade base 176 and the cutting edge 180 proximate the first end 168 and the second height “H2” between the blade base 176 and the cutting edge 180 proximate the second end 170. Further, the cutting blade 160 defines a longitudinal blade axis “B1” extending from the midpoint 178 to the center point 182 of the cutting edge 180. The longitudinal blade axis “B1” is generally orthogonal to the base surface 158. Moreover, the tape applicator 116 includes a first angle “A1” greater than 0 degrees between the Y-axis and the longitudinal blade axis “B1”. More particularly, the cutting blade 160 is inclined relative to the base surface 158 such that the first angle “A1” is defined between the Y-axis and the longitudinal blade axis “B1”. The first angle “A1” lies in a range from about 3 degrees to about 8 degrees. In one specific example, the first angle “A1” is approximately equal to 5 degrees. If the first angle “A1” is below 3 degrees, the cutting blade 160 may not allow efficient cutting of the adhesive tape 102. Moreover, if the first angle “A1” is above 8 degrees, a width “W” (shown in
Referring now to
The second angle “A2” may allow improved cutting action of the adhesive tape 102. It should be noted that the second angle “A2” is optimally selected to provide efficient cutting of the adhesive tape 102 without increasing complexity of the cutting section 131. If the second angle “A2” is very shallow, the cutting blade 160 may not demonstrate a cleaner cutting action. Whereas, if the second angle “A2” is very steep, the pinching head 184 may have to travel a comparatively longer path for cutting of the adhesive tape 102. Further, a height “h1” of the blade slot 190 and the height “H” of the first and second portions 162, 164 may also have to be increased in order to accommodate the cutting blade 160 having the steeper second angle “A2”. In some cases, the steeper second angle “A2” may complicate a design and assembly of the cutting section 131. Accordingly, in some cases, the shallow second angle “A2” may be preferred so that the height “h1” of the blade slot 190 and the height “H” of the first and second portions 162, 164 can be shorter and the adhesive tape 102 is not pulled deeply into the blade slot 190 during the cutting event. The shallow second angle “A2” may simplify the tape applicator design and also facilitate clean cutting of the adhesive type 102. In the illustrated example, the cutting edge 180 tapers along the length “L” of the cutting blade 160 such that the first height “H1” of the cutting blade 160 is lesser than the second height “H2” of the cutting blade 160. In another example, the cutting edge 180 may taper along the length “L” of the cutting blade 160 such that the first height “H1” defined at the first end 168 is greater than the second height “H2” defined at the second end 170.
As shown in
Moreover, at least one of the cutting head 156 and the pinching head 184 is movable from a first position with the cutting blade 160 disposed outside of the blade slot 190 to a second position with the cutting blade 160 disposed at least partially within the blade slot 190. The adhesive tape 102 is positioned between the pinching head 184 and the base surface 158 when at least one of the cutting head 156 and the pinching head 184 is in the second position. In the illustrated example, the cutting head 156 is fixed and the pinching head 184 moves with respect to the cutting head 156 during cutting of the adhesive tape 102. The pinching head 184 is movable between the first and second positions. The pinching head is illustrated in the first position in
Further, the tape applicator 116 includes a push button 194 for actuating at least one of the pinching head 184 and the cutting head 156 for cutting the adhesive tape 102. In the illustrated embodiment, the push button 194 is coupled to the pinching head 184. More particularly, the push button 194 is coupled to the base section 192 such that when an operator applies pressure on the push button 194, the pinching head 184 moves along the Y-axis (see
When the push button 194 is pressed by the operator, the pinching head 184 contacts the adhesive tape 102. Continual movement of the pinching head 184 pushes the adhesive tape 102 towards the cutting blade 160 of the cutting head 156, thereby cutting the adhesive tape 102. Moreover, as mentioned above, during cutting of the adhesive tape 102, the blade slot 190 at least partially receives the cutting blade 160 as the pinching head 184 travels towards the cutting head 156, as illustrated in
It should be noted that the arrangement of the cutting blade 160, the cutting head 156, and the pinching head 184 described herein allows efficient cutting of adhesive tapes having high elongation and low unwind forces. Further, the operator may only press the push button 194 for cutting of the adhesive tape 102. As the push button 194 is distant from the cutting blade 160, any possibility of injury to the operators may be eliminated. In another embodiment, the pinching head 184 is fixed and the cutting head 156 moves with respect to the pinching head 184 during cutting of the adhesive tape 102. In such an embodiment, the push button 194 may be coupled to the cutting head 156.
The cutting head 756 also includes a cutting blade 760 that is similar in design to the cutting blade 160 of the tape applicator 116 described in relation to
Further, the cutting head 756 defines a base surface 758 similar to the base surface 158 of the tape applicator 116 explained in relation to
The tape applicator 716 further includes a second bracket 711 extending from the base surface 758, such that the cutting blade 760 is disposed between the first bracket 703 and the second bracket 711. The second bracket 711 is substantially L-shaped. The second bracket 711 defines a second contact portion 713 that is spaced apart from the base surface 758. In some examples, the first and second contact portions 705, 713 may have a planar profile or a curved profile. In the illustrated example, the first and second contact portions 705, 713 include a planar profile. The second bracket 711 also defines a second vertical portion 715 that is perpendicular to the second contact portion 713. The tape applicator 716 further includes a second spring member 717 disposed between the base surface 758 and the second contact portion 713. A first end of the second spring member 717 rests against the base surface 758 and a second end of the second spring member 717 rests against the second contact portion 713. The second spring member 717 biases the second contact portion 713 towards the adhesive tape 702 thereby maintaining contact of the second contact portion 713 with the adhesive tape 702.
Further, the adhesive tape 702 is held between the first pinching projection 786 and the first contact portion 705, and the second pinching projection 788 and the second contact portion 713 when at least one of the cutting head 756 and the pinching head 784 is in the second position. In the illustrated embodiment, the pinching head 784 moves between the first and second positions while the cutting head 756 is stationary. Thus, when the push button of the tape applicator 716 is pushed, the pinching head 784 contacts the adhesive tape 702. Further, continual movement of the pinching head 784 causes the adhesive tape 702 to contact the first and second contact portions 705, 713. Accordingly, the adhesive tape 702 is held between the first pinching projection 786 and the first contact portion 705, and the second pinching projection 788 and the second contact portion 713 when the pinching head 784 is in the second position. A pinching or nipping of the adhesive tape 702 allows the adhesive tape 702 to be pulled deeply between the first and second pinching projections 786, 788, which in turn allows efficient cutting of the adhesive tape 702.
The cutting blade 160, 760 includes the dual angles “A1”, “A2”. The dual angles “A1”, “A2” provide efficient cutting of the adhesive tape 102, 702. Further, the dual angle cutting blade concept described herein is not limited to tape applicators involving direct application of the adhesive tape 102, 702 on the work surfaces 104, 704. In other applications, the dual angle cutting blade concept may be employed on cutting blades associated with table-top pull and cut tape dispensers, or any other tape dispensers of stationary nature, without any limitations.
Further, in some examples, the tape applicator 116, 716 may omit the push button 194, 794 for cutting the adhesive tape 102, 702 and the adhesive tape 102, 702 may be cut similar to table-top pull and cut dispensers. In other examples, the tape applicator 116, 716 may include a different means for advancing the pinching head 184, 784 towards the cutting blade 160, 760 for cutting the adhesive tape 102, 702, without any limitations. In an example, the push button 184, 784 may be replaced by a screw arrangement such that an advancement of a screw member connected to the pinching head 184, 784 causes advancement of the pinching head 184, 784 or the push button 194, 794 may be replaced by a lever or any other component that facilitates a plunging action.
The tape applicator 116 includes the Z-axis tangent to the base surface 158, passing through the midpoint 178, and may be parallel to the blade base 176, the cutting edge axis “B2” passing through the center point 182 and tangent to the cutting edge 180, and the second angle “A2” less than 80 degrees between the Z-axis and the cutting edge axis “B2”. The first angle “A1” lies in a range from about 3 degrees to about 8 degrees and the second angle “A2” lies in a range from about 10 degrees to about 18 degrees. Moreover, the adhesive tape 102 is coupled with the adhesive tape spool unwind 122 of the tape applicator 116. Further, the tape guide wheel 130 of the tape applicator 116 receives the adhesive tape 102 from the adhesive tape spool unwind 122. The tape guide wheel 130 is disposed proximate the cutting head 156 in an adhesive tape path 132
At step 804, the tape applicator 116 is moved along the work surface 104 for applying the adhesive tape 102 to the work surface 104. More particularly, the pair of guide rollers 146 of the tape applicator 116 contact with the first surface 106 of the work surface 104 for sliding the tape applicator 116 on the first surface 106. The first surface 106 is angularly disposed relative to a second surface 108 of the work surface 104 on which the adhesive tape 102 is applied. Moreover, at least one first magnet 144 attracts the tape applicator 116 towards the second surface 108 of the work surface 104 on which the adhesive tape 102 is applied. Additionally, at least one second magnet 154 attracts the tape applicator 116 towards the first surface 106 of the work surface 104.
At step 806, at least one of the cutting head 156 and the pinching head 184 is moved from the first position with the cutting blade 160 disposed outside of the blade slot 190 to the second position with the cutting blade 160 disposed at least partially within the blade slot 190. In one example, the pinching head 184 is moved with respect to the cutting head 156 for cutting the adhesive tape 102. In another example, the cutting head 156 is moved with respect to the pinching head 184 for cutting the adhesive tape 102. The tape applicator 116 also includes the push button 194. The push button 194 of the tape applicator 116 is actuated for moving at least one of the pinching head 184 and the cutting head 156 for cutting the adhesive tape 102.
At step 808, the adhesive side 112 of the adhesive tape 102 contacts with the pinching head 184 and the non-adhesive side 114 of the adhesive tape 102 contacts with the cutting blade 160 based on the movement of at least one of the cutting head 156 and the pinching head 184. In this example, the adhesive tape 102 is positioned between the pinching head 184 and the base surface 158 when at least one of the cutting head 156 and the pinching head 184 is in the second position. At step 810, the cutting blade 160 cuts the adhesive tape 102 based on the movement of at least one of the cutting head 156 and the pinching head 184.
In another embodiment, the method 800 includes a step of holding the adhesive tape 702 between the first bracket 703 extending from the base surface 758 of the cutting head 756 and the first pinching projection 786 of the pinching head 784 during cutting of the adhesive tape 702. The method 800 also includes a step of biasing the first bracket 703 towards the adhesive tape 702 via the first spring member 709. Further, the method 800 includes the step of holding the adhesive tape 702 between the second bracket 711 extending from the base surface 758 of the cutting head 756 and the second pinching projection 788 of the pinching head 784 during cutting of the adhesive tape 702, wherein the cutting blade 760 is disposed between the first bracket 703 and the second bracket 711. The method 800 also includes a step of biasing the second bracket 711 towards the adhesive tape 102 via the second spring member 717.
