ABSTRACT:
A method of and apparatus for manufacturing a pair of paper stringer tapes for slide fasteners from a pair of blank paper strips of a continuous length. The blank paper strips are fed lengthwise through a guide roller assembly. A pair of parallel spaced scoring wheels is biased against one guide roller of the guide roller assembly. As the paper strips pass between the one guide roller and the respective scoring wheels, a pair of continuous prospective folding lines of a constant depth is formed on the blank paper strips along the respective inner longitudinal margin thereof. The inner longitudinal margin of each paper strip is folded on the folding line to provide a doubled thickness with a folded edge on which a row of thermoplastic coupling elements is to be mounted. The support of the scoring wheels enables them to move toward and away from the strip, either jointly or individually, to compensate for variations in paper thickness, whereby said constant depth is maintained.
