SHEET 10F 2 INVENTOR. HISASHI HAMANO ATTORNEYS PATENTEDFEBZYIBH SHEET 2 BF 2 INVENTOR. HISASHI HAMANO BY ,6 /f7% i w ATTORNEYS METHOD FOR MAKING HOOK FABRIC MATERIAL FOR FASTENERS BACKGROUND OF THE INVENTION Hook and loop fasteners have found many applications and operate on the principle of having two interengaging surfaces one of loops and the other of hooks. Separation is effected by peeling one fastener element from the other. Much effort has been spent in SUMMARY OF THE INVENTION The present invention employs a base fabric having a series of looped piles in regular rows upstanding therefrom as a starting material. The rows of loops first are held by rods inserted therein and, in accordance with certain forms of the invention thereafter platens or rollers are to provide heat and pressure caused to pass over the upper ends of the rods thus effecting the conversion of the loops into various hooked forms. The invention further provides chemical means in combination with mechanical pressure for converting loops into hooked forms.

These and other aspects of the invention will become apparent from a detailed examination of the following description of preferred embodiments and of the accompanying drawing.

BRIEF DESCRIPTION OF THE DRAWING loop into two hook-like forms.

FIG. 5 is an alternate form of heated platen employing a similar method to that of FIG. 1;

FIG. 6 is a detail showing of the platen used in the apparatus of FIG. 5;

FIG. 7 is still another alternate form of apparatus to convert loops into a series of knob shaped hooks; and

FIG. 8 illustrates the use of a chemical bath to begin initial deformation of loops.

DESCRIPTION OF A PREFERRED EMBODIMENT .Referring to the drawing and initially to FIGS. 1-4 thereof, there has been illustrated a base fabric 10 which may be knitted or woven and upstanding rows of loops 11 has inserted therebetween a rod or mandrel 12 which will maintain the loops in their upstanding position. A first heated platen 13 will be passedover the tops of the loops 11 to melt the summits thereof (see FIG. 3). Thereafter, a second platen therefrom a plurality of rows of loops 11. Each of the 14 of cooler temperature will be passed over the now melted ends 11a of the two upstanding legs 1 1b of each loop 11 to press the still molten ends into knob 1111 as shown in FIG. 4.

In accordance with the apparatus of FIGS. 5 and 6, a variation of the apparatus and method of FIG. 1 has been shown. A heated platen 16 has a triangular shaped ridge 17 along the bottom thereof, the front end 17a being of sharp or fairly acute angular shape while the rear 17b of substantially flatter angular shape. The front end 17a is kept at a high temperature while the rear end 17b is kept at a lower temperature; consequently, the loops 11' will be heated and cut by the front end 17a and the passing of the rear end 17b will cause the half melted loops to be crushed to form into knob like projections such as those shown in FIG. 4.

In accordance with the embodiment of FIG. 7, loops 11 are held by rods 12 and are first subjected to the cutting action of rotary cutter 20. Thereafter, a heated roller 21 will pass over the cut ends to melt and crush the loop ends into the configuration of FIG. 4.

FIG. 8 discloses an alternate method employing the use of a chemical bath 22. In accordance with this method, fabric having upstanding loops 11 has passed over a roller 23 which dips the summits of the loops 11 into a chemical solvent. For example in the case of nylon, formic acid would be used. The chemical solution half melts the tip ends of the loops thereby softening them. Thereafter, the loops will be passed beneath a pressing roller 24 which crushes the softened tip ends, the applied chemical being removed by evaporation or other suitable methods to fix the shape of the deformed tip ends.

The above methods and apparatus as disclosed will produce a pile fabric which is very suitable for use as a fastener. The hook or the knoblike hooks formed will interengage with loop pile material or with other knob ended pile material.

It will be understood that the above description of preferred embodiments is merely representative and that reference should be made to the appended claims in order to o appreciate the spirit and scope of the present invention.

What is claimed is:

1. The method of forming knob-like projections from a multiplicity of pile loops upstanding from a flat base material to form a hooked pile surface suitable for use as a fastener element comprising, taking a flat base sheet having rows of loops upstanding therefrom made of a heat deformable material, rigidly supporting said loops in an uprightposition by placing a mandrel within said loops, applying heat and pressure to the summits of said loops to melt the summits while separating said loops to form separate upstanding legs, and thereafter cooling the ends of said upstanding legs while simultaneously pressing the ends of said legs into knob-like projections.

2. The method according to claim 1 wherein the step of applying heat and pressure is accomplished by passing a heated platen linearly along said rows of loops and the step of cooling and pressing is accomplished by passing a cooling platen linearly along said rows of loops.

3. The method of forming knob-like projections from a multiplicity of pile loops upstanding from a flat base legs while simultaneously forming the ends of said upstanding legs into softened partially formed knob-like projections and applying pressure to the ends of said legs to crush and to form the softened ends into knoblike projections.

Claims (2)

  1. 2. The method according to claim 1 wherein the step of applying heat and pressure is accomplished by passing a heated platen linearly along said rows of loops and the step of cooling and pressing is accomplished by passing a cooling platen linearly along said rows of loops.
  2. 3. The method of forming knob-like projections from a multiplicity of pile loops upstanding from a flat base material to form a hooked pile surface suitable for use as a fastener element comprising, taking a base sheet material having rows of upstanding loops made of a chemically deformable material, dipping the ends of said loops into a chemical solvent to cause separation of the summits of said loops into separate upstanding legs while simultaneously forming the ends of said upstanding legs into softened partially formed knob-like projections and applying pressure to the ends of said legs to crush and to form the softened ends into knob-like projections.
