A METHOD FOR PRESS-BONDING A REINFORCEMENT TAPE TO A SLIDE FASTENER WITH A SEPARABLE END STOP AND AN APPARATUS THEREFOR ABSTRACT OF THE DISCLOSURE A method and an apparatus are proposed for press-bonding a reinforcement tape of a plastic film on to a space section of a continuous length slide fastner chain to be finished into individual slide fasteners with a separable end stop so as to impart increased rigidity to the carrier tapes of the fastener chain at the end. The method comprises positioning the space section of the fastener chain between an upper presser and a lower presser and, on the other hand, transferring a continuous length reinforcement tape by a predetermined distance in a direction perpendicular to the movement of the fastener chain, the reinforcement tape having been provided with a cut-out to fit the element rows of the fastener chain, so that the cut- out is located just on the space section of the fastener chain between the pressers followed by closing of the pressers to effect press-bonding of the reinforcement tape to the space of the fastener chain either by heat melting or by high-frequency welding with simultaneous cutting of the reinforcement tape with a cutter blade.
