USE

The roll feeders are designed to feed coil strip into the working space of metalforming machines. They are preferably applied in current metalforming operations such as blanking, punching, bending etc. and realize a high degree of feed length precision. The feeders can be attached without much demands to separate forming machines or machines integrated in forming lines.

You may inquire on a specific type and application of a roll feeder using a FORM.

(*) Maximum time or angle for feed is the value when the strip to be feed is released (by the punches) and renewed forming starts. The selection of these parameters is arbitrary.

 (**) A condition for the operation of a numerically controlled roll feeder is the formation of the loop between the straightener/uncoiler and the feeder. The loop in our case is controlled by optical sensors.
