Ea is often desirable to form face zipper halves Ribbons on a wide variety of fabrics, such as to be attached to items of clothing to create a plaque zipper «. So far, such surface tear spine halves have been used usually sewn to the material underlay were used, made individually for each belt part, and was therefore time-consuming. There are also possible applications of surface zip fastener parts on such Conceivable underlays to which these cannot be sewn, such as non-woven garments for medfeinisehe Purposes.

The invention is based on the object of specifying a method with the strip parts one after the other from one long, pliable tape can be separated so that a subsequent simple and precise application of the severed tape parts to a fabric underlay is possible.

The object is achieved according to the invention in that that tape is held flat in the area to be cut that a free end portion of the tape while maintaining the flat state · of the belt in front

During the transport and surrendering processes, it is constantly ensured that the sheet-lax tape part to be severed and severed maintains its flat state »

The cutting device includes one in communication therewith standing hold-down device for the tape as well as cutting punch for cutting out the angular cut-outs and Cut off the end pieces one at a time in this order.
