ABSTRACT:
A method and an apparatus for press-bonding a reinforcement tape of plastic film onto a space section of a continuous length slide fastener chain, the method and the apparatus comprising means for positioning the space section of the fastener chain between an upper presser and a lower presser providing the reinforcement tape with a cut-out to fit the element rows of the fastener chain, transferring a continuous length reinforcement tape by a predetermined distance in a direction perpendicular to the movement of the fastener chain so that the cut-out is located just on the space section of the fastener chain between the pressers, 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, and simultaneously cutting the reinforcement tape with a cutter blade.
