ABSTRACT:
A method of stacking a multiplicity of fabric strips attached with a slide fastener chain one upon another is disclosed, which comprises folding each of the strips in halves along the longitudinal axis of the fastener chain, clamping the fabric strip from both sides closely at its folded edge, cutting the trailing end of the fabric strip and depositing the thus cut fabric strip upon and in registry with a stack of previously accumulated fabric strips. An apparatus is also disclosed for carrying this method into practice, which essentially comprises a gate means having a guide slit through which a slide fastener chain is passed, a gripper means releasably gripping a leading end of the fastener chain, and a clamping means releasably clamping the fabric strip from both sides closely adjacent at the fastener chain.
