Abstract
A clip-separating machine is provided with a guide frame, a clipper, and a displacement structure. The guide frame is configured to support a strip of clips. The clipper has a pair of opposed cutting edges. One of the edges is supported for movement toward and away from another of the edges. The displacement structure is configured to move the one cutting edge toward the other cutting edge so as to cause co-action of the cutting edges to sever a terminal clip from a strip of clips. A method is also provided.
Claims16
A method of severing a clip from a strip of clips that are each configured to close a bag, comprising:
- providing a serially arrayed strip of clips with each adjacent pair of clips joined together with a non-frangible tab;
- advancing the strip of clips between a pair of coacting cutting edges to position each successive non-frangible tab between the coating cutting edges;
- and
- displacing one cutting edge toward another cutting edge to impart coaction of the cutting edges in order to sever a terminal clip from the strip of clips along the non-frangible tab.
A method of severing a clip from a strip of clips that are each configured to close a bag, comprising:
- providing a pair of coacting cutting edges, a serially arrayed strip of clips, a guide track for guiding the strip of clips joined together by tabs for sequential axial delivery of individual clips, and an index delivery mechanism for incrementally delivering indexed successive tabs for severing between the coacting cutting edges, with each adjacent pair of clips joined together with one of the tabs;
- advancing the strip of clips between the pair of coacting cutting edges to position each successive tab between the coacting cutting edges;
- and
- displacing one cutting edge toward another cutting edge to impart coaction of the cutting edges in order to sever a terminal clip from the strip of clips along the tab.
