ABSTRACT:
A method of manufacture comprising the following steps: (a) continuously advancing a web of bag making material at a first rate; (b) continuously joining portions of a downstream portion of a fastener tape to respective portions of the continuously advancing web of bag making material; (c) intermittently advancing an upstream portion of the fastener tape while the downstream portion is advancing continuously, the halt at the end of each intermittent advance being the start of the next work cycle, the upstream portion of the fastener tape being stationary during a respective dwell time of each work cycle and advancing during the remainder of each work cycle at a second rate faster than the first rate; (d) accumulating a portion of the fastener tape disposed between the upstream and downstream portions to compensate for the difference in the first and second rates during the aforementioned remainder of each work cycle; and (e) inserting a respective slider onto the upstream portion of the fastener tape during each dwell time.
