Infeed apparatus for a sheet material article trimmer

摘要

An infeed apparatus for a sheet material article trimmer includes a pusher element for moving a sheet material article to be trimmed on a front table of the trimmer and into engagement with a backstop of the front table. The pusher element is moved by a driver which moves the pusher element at the same speed as the front table for a period of time with the pusher element in engagement with a back edge portion of the sheet material article and the backstop in engagement with a front edge portion of the sheet material article. The period of time is at least as long as the time required for a front clamp of the sheet material article trimmer to grip the sheet material article against the front table. A method is also provided.
