 be supported.

   After pressing down, there is still sufficient space in the screw turns to be able to insert a collecting core 19 into the turns of the two belt ends (FIG. 5).

Claims

Since the needles are very heavily stressed during pressing by the thick and firm belt, it is of the greatest importance that they are securely fastened in the device.

A particularly advantageous method of fastening is that shown in FIGS. 3 and 4. There is a number here, e.g. B. five cross rails 20 are used, in the front edge of which holes are formed for the needles. Since these holes are difficult to drill crookedly in the collapsed rails or in a single thick rail, they will be drilled straight through each of the rails and the screw wire can then be passed through all of the rails by using the same as shown in FIG Location holds. Of course, the holes must have a sufficient width. After the needle wire is inserted, the rails 20 are pressed together and it is EMI2.1 brought.

The wire parts not to be used for the needles are then cut off and the ends of the needles are sharpened, after which a splint 22 is attached under the base of the needles for the purpose of a good hold of the whole body and connected to all splints 20 by screws 23. These screws can be of such a length that they can also be used to fasten the needle body to the device 3. Such a needle body can easily be attached to the device and removed again when the needles are worn or damaged.

PATENT CLAIMS: 1. Apparatus with a punching and pressing device used for attaching helical connecting wires in drive belts, characterized in that the punching device EMI2.2 are of the same pitch as the helical connecting wire. while the device for pressing down the turns of the screw wire screwed into the belt ends consists of a resilient pressure bar (lu) which is attached between an eccentric roller (13) and a support rail (17) provided with support guides for the screw turns.

2. Apparatus according to claim 1, characterized in that the needles (4) are guided through a number of loose rails (20) which are joined together and provided with a support rail (23).
