Abstract
Abstract In trimming moils from plastic articles with a blade interposed in a path along which the articles are moving while engaged with fixed and moving guides, the improvement downstream of the blade is provided of a rotatably driven moil discharge wheel and an opposite cooperating anvil forming a moil discharge path between them. The process improvements involve engaging the moil after cutting by the blade with the surfaces of the wheel and anvil and conveying the engaged moil along a path away from that taken during cutting by means of the revolving wheel.
