Top Print Prefeeders
Automatic Overturn Top Prefeeder
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.
