Turn bar apparatus

摘要

A turn bar apparatus is incorporated in a rotary press for reversing a web position during running thereof. The turn bar apparatus includes an upstream side turn bar, and a downstream side turn bar disposed along a web running direction. Pull rollers are disposed on an upstream side and a downstream side of the upstream side and downstream side turn bars, respectively. The puller rollers are controlled in such a manner that the peripheral speeds of the pull rollers are faster than a running speed of the web.
