Bandmotion feeders operate with two pneumatic cylinders and four very solid linear precision guides to lift and guide the upper roller during pilot release. This technology guarantees a stable, torsion-free and balanced press-force between the lower and upper rollers.
Broad and heavy-duty feeders have the linear guides and pressure cylinders arranged in such a way, that common deflection and twisting forces will be evenly balanced in the pressing unit.
With the two-cylinder technology, the total air volume is distributed evenly into two individual cylinders with smaller air capacity. Thus, each cylinder can be ventilated and de-ventilated quicker and as a result, the system can achieve very high pilot release rates.
This technology eliminates any rocker systems and the rollers can be exchanged in a short time and without disassembling the feeder.
Due to this clever two-cylinder design, the travelling distance during pilot release can be adjusted upwards and downwards. This is a great advantage, especially when feeding very soft materials into the press or to avoid damages on hard coated rollers while operating the feeder without materials in-between the rollers.
The Bandmotion roller system is a clever 3-piece design and the roller ends can be detached from the center part. This allows a fast and economic replacement of worn parts only, instead of replacing the whole roller.
