Rapida 75 C (QAPC)
Feeder
- High- performance stream feeder
- Antistatic rear-edge separating air blast
- Pallet feeder with pile side edge alignment for enhanced productivity
- Rear-edge pile height sensing and compensation of feeder head height
- Sucker tilt adjustmentto draw paper tight at the feeder head
Suction-belt feed table
- Stainless, antistatic structured surface, two suction belts and multi-chamber vacuum system
- Electronically controlled sheet deceleration by 70% to ensure optimum sheet arrival speed at the front lays
Infeed
- Swing infeed accelerates the sheet for transfer to a single-size feed drum
- No need to adapt the front lay cover height to changes in substrate thickness
- Adjustment of the feed line at the infeed
Sheet monitoring
- Ultrasonic double-sheet detector
