ABSTRACT:
A plurality of skewing devices are mounted in a collating apparatus above collating points at which a plurality of webs are collected together for further processing. The skewing devices comprise rollers mounted on shafts which may be rotated by a handle. Each shaft has a threaded section, and a threaded block is mounted thereon for axial movement in response to rotation of the handle. There is a link bar pivotally linked to the threaded block, so that axial movement of the threaded block causes pivotal rotation of the link bar. Such pivotal rotation of the link bar causes the threaded block to rotate the shaft in a horizontal plane for controlled skewing of the web.
