ABSTRACT 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 the work station web velocity at the time the tool means contact the web is sub- stantially equal to the tangential velocity of the tool means. The method of the invention calls for thus adjusting momentary work station web velocity to match the tangential velocity of the tool means while maintain- ing a constant average web velocity through the tool assembly.
