Abstract
In a machine of the type in which cutting tools are arranged on successive links of an endless chain, each tool being in offset rotation to the preceding tool, at right angles to the direction of travel, means are provided for periodically shifting the workhead and work spindle parallel with the plane in which the tools travel when cutting. The means for shifting are operatively independent of the means for driving the chain and the work spindle in generation, and are operated when the tools and workpieces are disengaged, and normally after a predetermined number of stacks of workpieces has been cut, in order to equalize wear on the blades carried by the chain.
