Apparatus and method for synchronizing advance of web and rotational speed of bucket or like member

Abstract From the Canadian patent

A tool assembly includes first and second means which define between them a work station at which they periodically engage and release a moving web of material to perform a work operation such as die cut-, ting, on the web. A reciprocating shuttle has a pair of guide rollers on it which respectively engage the web before and after the tool means to alternately increase and decrease the work station velocity of the web by alternately decreasing and increasing the web path distance between the shuttle and the work station. The frequency of tool means movement is adjustable to adjust the repeat between work operations on the web. The shuttle means are synchronized with the tool means so that …
