Prefeeders

The WSA Top Print Overturn Prefeeder is designed for today’s most advanced top printing Mini-line and Mid-Size Flexo Folder Gluers that run at speeds of up to 450 sheets per minute and features very quick setups. This model inverts the entire stack in one motion, advances the stack onto an extendo conveyor and into a pre-hopper, then delivers a continuous shingle of board to the press. This design maximizes the amount of board which can be stored on the extendo conveyor and delivers the most consistent stream of board to the press even when handling very small blank sizes.
