METHOD OF AND APPARATUS FOR DECREASING THE SPACING BETWEEN ARTICLES

摘要

The spacing between articles depending from a deformable strip of stock material is decreased by crimping the strip between each adjacent pair of articles. The crimps are formed at spaced intervals starting with the centermost portions of the strip and progressing outwardly therefrom until a crimp is formed between each adjacent article pair. Crimping is accomplished by an arrangement of concentric piston-rams which are sequentially moved to advance pairs of forming tools to crimp and decrease the length of the strip of stock material.
