PUNCHING UNIT MODEL PU14 The PU14 PUNCHING UNIT is a device designed to punch holes in the outer edge of the moving film and in particular, it works with plain or printed film. It has to be integrated into existing machinery such as extruders, slitters, bag making machines, printing machines or any other film processing lines. They are perfect to punch SHAPED HOLES, such as HANDLE, DROP and EUROSLOT HOLES. Important parts of the device This model consists of a basic structure called a “body” with a perforation tool consisting of a hammer and die system connected to a solenoid valve. As an option, we can provide an electronic control system with 4.0 predisposition. In this model the distance between the center of the hole and the edge of the material goes from min. 50mm to max. 200mm. The edge of the moving film passes through the slit of the body and is punched by the perforation tool mounted at the front of the device. Punching is carried out through a punch and die system, using pneumatic movement. It is possible to obtain holes of various diameters and shapes, depending on the punches and dies used. It is possible to create holes with a Ø from 0.5mm to 50mm with the following shapes: circular holes, euroslot, handle holes for bags, valve holes, shaped or custom according to the Customer's indications. La velocità operativa massima raggiunta dall’unità è di 200 mt/min, con How the PU14 works: handle holes on moving frequenza massima di 35 Hz. Si ricorda che questa misura è influenzata material dalla composizione del materiale da forare e dalla distanza dei fori e che le migliori performance dell’apparecchio vengono raggiunte installando l’unità nella fase di lavorazione in continuo della linea ospitante. Encoder It is possible to equip this unit with only 1 perforation tool at the front. Back and side view

The perforation tool consists of two parts: 1. a male body, which houses the punch, placed at the top and connected to the solenoid valve above. 2. a female body, which houses the die, placed at the bottom. The hole is made through this punch and die system, using pneumatic movement and is controlled by the solenoid valve. The lower part of the female body is designed to connect to a suction tube, which facilitates evacuation of processing waste. With this system it is possible to punch holes of various diameters and shapes: circular with diameter from 0.5 * mm to 50mm, valve holes, handle holes,...
