"Flexible, with hook-shaped bent thread elements

Volume ¹¹

The invention relates to the known with a hook-like design Thread elements, which by cutting through the one Side thread of the free loops of corrugated threads, soft on a flexible base body through the embedded in this The vertices of the loops forming the opposite corrugations of the threads are attached, provided with flexible bands, which by hooking these hooks into closed exposed loops of another such pliable tape with that in through Exercising a pulling action are releasably connected.

In these known tapes the free loops are cut at a certain distance from their apexes, so that the loop area of the loop which forms the hook, its handle, is firmly connected to the flexible strip by soft

is through. <Len other silk thread is formed in the loop in question is retained.

The one opposite the side thread that forms the hook handle separated part of the other side thread can however, the hooking of the cooperating loop element hinder on the other strap in the hook. In fact, this familiar arrangement is more similar in design a kind of Ka.rabinerh.aken, as an open hook.

The invention provides a hook-shaped thread elements provided flexible tape created, which does not have the disadvantages of the known design described.

This is achieved according to the invention in that the part of the thread forming the loop which is the part of the loop which Aen. The hook leg forms, opposite, in the area of the surface of the base body from which the thread continuing into it is cut.

This creates the space between the bent end of the Hook and the .Gründkörper completely exposed, so that ns now is possible, one on the main body of the other band, which to be releasably connected to the first band, seated

Loop eneialement without difficulty in front of the hook spend and hook into these.

The manufacture of such a product takes place according to that in the German patent. ... ... (Patent application B 59 986 "Process and device for the production of flexible belts provided with thread-like, hook-shaped or loop-shaped parts" and the German patent. ... ... (Patent application B 79 342 Ί / 39β2) "Automatic cutting device for machines for producing flexible strips provided with hook-shaped parts".

In addition to cutting the loops a certain distance from their apexes to form the hooks, all that is needed is in the area of the surface of the base body that is opposite to the side thread of the loop, which forms the hook handle part thereof separated from the hook to be cut away. ■ ■ '.

This process is very easy to carry out because the Wurzexn the loops in small elevations of the G-round body forming Plastic are embedded. The relevant side threads of the loops are directly on the upper, surface the- * cut off this embedding so that there is no risk of -.-. :: ·

that they lie down under the pressure of the cutting blade. The cutting off is made even easier by the fact that the partial threads of the loops on one side against the rod body are determined by which in the manufacture of the flexible Belts are formed into loops according to the known method mentioned above. , '

The invention is described in detail below with reference to the figures described which as an example on which the invention but is in no way limited to an embodiment of one with thread-like hook elements provided flexible tape with the Illustrate features of the invention.

Fig. 1 is a longitudinal section on an enlarged scale through a Part of one provided with the hook-shaped thread elements flexible tape.

Fig. 2 is a section along line II-II of FIGS. 1 and

Prop. 3 is a longitudinal section illustrating an intermediate phase in the manufacture of the tape shown in FIG.

ordered from a base body 1 made of plastic, in which firmly, - so that they form a uniform body with the G-round body, - the inner loops 2a are anchored by corrugated, pxarallel threads 2, the outer loops 2b, as in A in S ¹ Ig. 3 can be seen, are cut through so that the remaining parts form the hooks 2b, the stalls of which are formed by the parts 2a of the outer thread loops.

The part of the outer one opposite the handle 2c of the hook Loop 2d can, as stated above, form an obstacle for the hook 2b when this is in an associated on another base body, which is detachable with the & ru4dkörper 1 Should be connected in a manner, the seated loop element should be hooked «.

According to the invention, this problem is eliminated in that the side threads of the loops separated from the hook body, as indicated at 8, essentially in the alignment

f of the surface of the base body 1 are cut off, which are then no longer connected to the object and fall off, so that the final state of the flexible strip shown in FIG. 1 results. In this figure the point ü is indicated at which the second cutting of the loops takes place.
