ABSTRACT:
In a method of cutting a continuous slide fastener chain into individual slide fastener lengths, the fastener chain is tensioned between its leading end and a succeeding element-free portion as they are gripped by downstream and at upstream grippers, respectively, at a specified point and a cutting station spaced upstream therefrom along a horizontal straight path by a varying distance corresponding to the length of a prospective individual slide fastener. Then the tension of the individual slide fastener length of the chain is relaxed by slightly moving the downstream gripper from the specified point toward the upstream gripper which is kept stationary at the cutting station, whereupon the fastener chain is cut transversely across the succeeding one element-free portion.
