Plastic film microperforating unit CNM 100

This equipment is designed to make micro holes on moving films of various materials and thicknesses and is to be inserted as a host unit in film processing lines, such as in slitters, extruders, printing and welding machines. The CNM100 is a motorized unit with a synchronization system that ensures perfect micro holes on a variety of materials. The CNM100 is a micro needle perforator in which the running film arrives at the device and passes between the motorized needle shaft and the counter roller, which as they approach each other perforate the material. Micro perforation is accomplished by perforating the material, caused by the needles infixed on the interchangeable bronze sleeves that are mounted on the needle shaft. The operation of the CNM100 is entrusted to our software ready for 4.0; from the electrical control panel, the operator (via touch screen) manages all operations inherent to the device such as needle roller rotation, speed or control of emergency signals. The movement is by means of an integrated asynchronous motor with driver and encoder and "tracking" function that allows the needle shaft to adapt to the speed of the moving film, resulting in flawless holes even with the most difficult materials and with high-density perforations. The motor allows the device to adapt perfectly to the speed of the host line. During perforation, the material to be micro-perforated is supported and brought closer to the needle shaft by a counter roller made of ground bristles or rubber. The penetration depth is adjusted by manual control using the special micrometer screws located above the casing.
