Apparatus for metering an elongate chain

摘要

A method of and an apparatus for metering an elongate stringer chain (C) to be finished into slide fasteners of different lengths, the metering being based on an element pitch P derived from dividing a given metering length L by the number of coupling elements (E) thereon. The stringer chain (C) is held substantially in tensionless suspension while it is being metered to achieve a maximum of metering accuracy.
