The unwinder has been designed to unwind and align rolls of heavy fabric which with other equipment like the cradle or the spreader could not be unwound. It also detaches plastic fabrics which stick to the roll.
Can be interfaced with any cutting machine.
The particular supply system permits adjusting the tension of the fabric so it remains uniform for the entire feed length. The high operating speed and a large load capacity make it the perfect tool for easily unwinding PVC and technical textiles with high rigidity. The possibility exists of fitting a self-aligning roll cradle for a single roll with max diameter 300 mm and, if required, a 5-roll rack.

LC1 is a new type of unwinder with automatic transversal cut used to cut the fiberglass plate wrapped in rolls which are located on a cage with cylinders on bearings that allow free rotation.
Below is the complete procedure for working the unwinder with automatic transversal cutting:
1. Loading the roll in the fixed part of the unwinder;
2. Inser the material between the front rollers to pull the unwinder;
3. Manual handling of the rollers for material heading;
4. Setting of parameters for automatic cycle on touch screen:
– Activation of alignment of the material through a group of sensors during the advancement phase;
– Speed regulation of the progress state up to a maximum of 400mm / s;
– Modification of the transversal cutting speed by an angle grinder;
– Possibility to choose the length of the cut;
– Opportunity to decide the number of cuts.
5. Start of the processing cycle;
6. Blocking of the material through a series of pressure cylinders for the entire cutting operation;
7. Application of the transverse cut and return of the tool to the original position;
8. Lifting of the group of pressure cylinders;
9. Material advancement phase for the length previously set;
10. Repetition of the procedure from the locking of the material with the cylinders according to the number of cuts set.
The overall period for a progress and a cut of 2 meters in length is on average 25 seconds.
