Film Roll Slitting Rewinding Machine

In the film and paper converting industry raw materials are typically provided in large wide master rolls. These rolls are heavy and awkward so they can not be sold or finished as is - they have to be slit, cut to length and rewound into smaller, usable rolls. That is where the film slitting and rewinding machine comes in. It's a versatile unit that handles all kinds of flexible web materials: PET, OPP, PE, PVC, metallised film, multi-layer composites, packaging laminates, pearlescent film, anti-glare matte film, and also paper-based rolls like kraft, masking tape paper, and release liner. That makes it a great all-rounder for small to medium-sized workshops.

Entry-level slitting machines often fall short in precision and stability. You get common headaches like web wandering, rough edges, and uneven winding tension, all of which hurt your yield. This machine, however, is built to avoid those problems. Its frame is a single piece of cast iron, giving it solid rigidity. It runs smoothly for hours on end without shaking or warping, and it lasts much longer than ordinary equipment. The working width can be set anywhere from 200 mm to 1600 mm, and slitting accuracy is within ±0.1 mm – tight enough for most industrial specs.

To guaranty consistent performance, important parts are purchased from reputable companies. A Delta VFD, Schneider low-voltage gear, an intelligent tension board, and a Siemens PLC are all used in the control system. The interface is a Kunlun Tongtai touchscreen, clear and easy to navigate. New staff can pick it up quickly – just punch in material thickness, width, and speed, and the machine takes care of the rest. This cuts down on manual work and labour costs.

On the functional side, it's well equipped. An optical edge-guiding system with linear rails constantly tracks and corrects web deviation, so you avoid misalignment. You can choose between straight or circular knives (straight is the default), giving you clean, burr-free cuts. The dual-shaft alternating rewinding setup, combined with adaptive tension control, produces tight, flat rolls with neat edges – no extra trimming needed. It also counts length automatically, stops at preset lengths, and warns you when material is running low, helping to reduce waste.

The machine runs at up to 200 metres per minute, smoothly and reliably, making it ideal for high-volume continuous production. It uses quality NSK bearings and reliable pneumatic parts, so breakdowns are rare and maintenance is easy. An integrated centrifugal fan blows away scrap edges, keeping your workspace tidy. All in all, this machine delivers a good balance of precision, speed, and cost-effectiveness. It's a solid, dependable piece of kit for converting most films and papers in the light industrial sector.
