The WSA Top Prefeeder (Compact) was first introduced in 2014 and 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 which feature very quick setups. This model works the entire stack in one motion, advances the stack onto an extendo conveyor and then 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.

• Stack Inverter with vacuum control of bottom sheet
