Definitions
- Tape fasteners are already known in which two tapes can be joined together by pressing them against each other.
- One tape is usually a loop pile fabric, and the other tape has projections attached to a surface, shaped so as to hook into the loop pile.
- projection end There are two known shapes of projection end, one consisting of a hook and the other being a bulbous shape commonly referred to as a mushroom.
- the hook type projection does not damage the pile fabric, but is relatively expensive to produce; whereas the mushroom type projection is cheaper to manufacture, but tends to tear the pile fabric, and thus shortens the life of the fastener.
- a method of producing a tape having hook type projections for a tape fastener including producing a tape so as to have straight projections projecting from one side of the tape, the projections being formed from a heat deformable material, and deforming the terminal end of each projection to form a hook by the application of appropriate heat and pressure.
- the tape is woven and is produced by weaving two tapes simultaneously which are separated by strands of a thermoplastics monofil yarn, the strands being severed to separate the tapes to produce two tapes having straight projections.
- Figure 1 is a schematic side view of a tape having straight projections prior to deformation
- Figure 2 is a schematic side view similar to Figure 1 showing the tape during deformation
- Figure 3 is a side view similar to Figure 1 showing the tape after deformation;
- Figure 4 is a schematic side view of an apparatus for deforming the projections to produce tape as shown in Figure 3;
- Figure 5 is a schematic perspective view of a first tape for co-operation with the tape of Figure 3;
- Figure 6 is a schematic perspective view of a second tape for co-operation with the tape of Figure 2.
- FIGs 1 to 4 in which there is shown a tape 1, woven from any suitable yarn, having straight projections 2.
- the projections 2 are interwoven with the tape 1 and are formed from a suitable thermoplastics yarn such as a polyamide monofilament yarn.
- the tape 1 is produced by weaving a pair of tapes simultaneously with the two tapes being joined and spaced from one another by strands of the thermoplastics yarn.
- the thermoplastics yarn is heat set and then severed to produce two tapes as shown in Figure 1 with straight projections 2.
- the tape 1 is presented to a hot surface 3 (shown in Figure 2) so that the terminal ends of the projections engage surface 3.
- the temperature of the hot surface 3 is chosen to be such as to cause softening of the thermoplastics from which projections 2 are made without causing melting.
- the time period of contact between the projections 2 and hot surface 3 is chosen so that only the terminal portion 4 of the projections 2 is softened. The tape 1 is pressed toward the hot surface
- the terminal portions 4 deform as shown in Figure 2.
- the surface 3 is chosen to be rough enough to restrain sliding movement of the projections 2 over its surface so that the non-softened portion 5 of each projection is resiliently deflected as seen in Figure 2.
- the tape 1 is removed from the hot surface and the deformed projections are cooled. Removal of the tape 1 from surface 3 permits the non-softened portions 5 to return to their original positions thus providing a tape 1 as shown in Figure 3.
- the apparatus 20 includes a support 13 over which tape 1 is passed.
- the support 13 may be in the form of a table or conveyor.
- a continuous belt 14 is arranged above the support 13 and is movable about a pair of guide rollers 14a, 14b in the direction of arrow M.
- the outer surface of the belt 14 is sufficiently rough to restrain relative movement between itself and the projections.
- the rate of movement of the belt 14 is arranged to be the same as that as the rate of feed of tape 1 so that there is no relative movement between the belt 14 and tape 1 during its passage across support 13.
- the belt 14 is also guided over a hot plate 16 which has an inclined wall portion 16a and a linear portion 16b which is substantially parallel to the surface of support 13.
- the gap between the linear portion 16b and the surface of support 13 is less than the combined thickness of tape 1 and undeformed projections 2.
- the incline of portion 16a, the temperature of the hot plate and the rate of feed of the tape 1 are all chosen so that the deformation as shown in Figure 2 is achieved by the time the deformed projections leaves the hot plate 16.
- a cooling plate 15 is provided downstream of hot plate 16 to heat set the deformed projections 2.
- the mating area of the mating tape may be conveniently in the form of a flat open mesh structure which could be either woven or knitted.
- One embodiment of such a tape ( Figure 5) has the open mesh 7 supported on cords 8, with a backing fabric 9 to fasten it on to the product such that there is a gap 10 for receiving the hook end of the projections when pushed through the mesh 7.
