A slider handling apparatus has a pressure roller and a drive roller peripherally engageable therewith to transfer a slide fastener chain assembled with component parts including sliders. A slider arresting means is operatively associated with the pressure and drive rollers for arresting sliders one at a time on the fastener chain at a predetermined point on the path of travel of the chain, the predetermined point being upstream of or in advance to the nip of the two rollers.

Firstly, elongated tape-like articles from a finishing machine are received one by one on a horizontal first pallet above a tray in a bundling or packing station and are then released therefrom the individual article to fall upon receipt. Secondly, the successive articles from the first pallet are received on a horizontal second pallet between the first pallet and the tray to store the articles in stack, and are then released all of the stored articles from the second pallet to fall as a set onto the tray when the number of the stored articles reaches a first predetermined value. When the number of sets of the articles stacked on the tray reaches a second predetermined value, the entire stack of the articles are bundled or packed and are then removed from the tray.

Method and apparatus for stacking elongated tape-like articles

A punch blade depresses the coupling heads of a length of successive filamentary coupling elements toward a knockout blade while sandwiching stringer tapes between upper and lower grippers. The punch blade is lowered until lower legs of the coupling elements are cut off by cutter blades. The punch blade and the knockout blade are then lifted while gripping the severed coupling elements therebetween to forcibly remove the coupling elements out of engagement with sewing threads on the stringer tapes. The upper grippers have confronting steps for engaging the sewing threads so that the severed coupling elements can be detached reliably and smoothly from the stringer tapes without unduly tensioning the sewing threads and stringer tapes. The punch blade may have a vertical reinforcement member attached to at least one side edge thereof and having a lower tooth projecting downwardly beyond a lower edge for being pressed against the coupling elements. The lower tooth enters between adjacent coupling elements to position the coupling elements against unwanted longitudinal displacement with respect to the punch blade.
