CONTINUOUSLY OPERABLE TOOL FOR USE IN PRODUCTION LINE PROCESS

摘要

The present invention relates to a continuously operable tool for use in a production line process, and to a process using one or more such tools. The tool is capable of handling a plurality of workpieces simultaneously and comprises a rotatable assembly such as a drum having a series of workpiece handling stations spaced around its periphery. Workpieces are picked up one by one on the drum as each handling station passes a pick-up point during each revolution of the drum. Each workpiece is carried round on the drum until it reaches an exit point, where it is transported away from the drum. Each workpiece handling station includes at least one workpiece manipulation device which reciprocates back and forth between an inoperative position and an operative position in which it operatively engages a workpiece at the station between the pick-up point and the exit point.
