The Slip Differential Shafts Slitting Machine with Shaftless Unwinding is a roll to roll converting system designed for cutting wide material rolls into multiple narrower rolls. The equipment integrates shaftless unwinding, slitting units, tension control, and slip differential rewinding into one production line. Materials are loaded from the shaftless unwinding section and transported through guide rollers to the cutting unit where multiple blades divide the material into smaller widths. After slitting, the material strips are rewound simultaneously onto multiple cores through the differential winding shaft system.

The machine structure allows operators to monitor material movement and cutting operations from the front control panel. The shaftless unwinding structure supports large roll loading and stable material feeding. The integrated control interface allows technicians to manage machine running conditions, monitor tension status, and observe slitting performance during continuous converting processes.

High Speed

The slitting machine supports continuous converting with a maximum operating speed of 600 meters per minute. This speed capability allows large master rolls to be processed efficiently in high output production environments. The coordinated roller system and cutting units maintain stable material movement even at high running speeds. Processing speeds up to 600 meters per minute allow long material rolls to be converted quickly while maintaining stable cutting performance. This ensures high productivity during industrial slitting operations.

Wide Width

The machine supports wide material processing with maximum material widths ranging from 1300 millimeters to 2500 millimeters depending on the configuration. This capacity allows large master rolls to be processed within one production cycle. The slitting section divides the wide material into multiple narrow strips while maintaining stable alignment during the cutting process. The system also supports minimum slitting widths down to 50 millimeters, enabling flexible roll conversion according to production requirements.

Large Rolls

The equipment supports large roll handling capability in both the unwinding and rewinding sections. The technical specifications indicate that the maximum unwinding diameter and rewinding diameter can reach 1000 millimeters. This allows large material rolls to be processed continuously without frequent roll replacement. Processing larger roll diameters improves production efficiency by reducing downtime associated with roll loading during converting operations.

Stable Control

The machine integrates a centralized motion control system based on SIMATIC motion controller technology and servo drive systems. This control architecture coordinates the movement of rollers, cutting units, and winding shafts during operation. The integrated control system ensures stable material transport and precise cutting positioning throughout the slitting process. Coordinated control improves the stability of high speed operations and supports consistent machine performance during continuous production cycles.

Shaftless Feed

The shaftless unwinding structure allows large master rolls to be loaded directly without using a traditional shaft core holder. This configuration supports fast roll loading and improves efficiency during material replacement. The shaftless feeding system also provides stable roll support during material unwinding. Combined with dancer tension detection and automatic control mechanisms, the shaftless structure helps maintain stable material feeding during high speed slitting operations.

Breathable Film

Breathable films used in hygiene product manufacturing are typically produced in large roll formats before converting. The slitting machine processes these rolls and divides them into multiple smaller widths suitable for downstream production processes. With minimum slitting widths reaching 50 millimeters, the equipment allows precise conversion of breathable films into narrower rolls for further manufacturing operations.

PE Film

PE films are widely produced in large master rolls and require slitting before being used in converting equipment. The slitting machine processes PE rolls with widths up to 2500 millimeters and converts them into narrower finished rolls. Continuous roll slitting ensures that large PE material batches can be prepared efficiently for downstream industrial processing.

Laminated Film

Laminated film materials are often produced in wide roll formats and must be slit into specific widths before further manufacturing steps. The slitting machine divides laminated film rolls into smaller strips while maintaining stable alignment across the material width. High speed slitting allows laminated film rolls to be converted efficiently during industrial production cycles.

Release Film

Release films used in industrial material applications are typically supplied as wide rolls. The slitting machine processes these rolls through multiple cutting blades to create narrower finished rolls. With operating speeds reaching 600 meters per minute, large release film rolls can be converted quickly during continuous production operations.

Paper Rolls

Paper materials are commonly supplied in large rolls that require slitting before use in packaging or converting industries. The slitting machine processes these rolls and divides them into multiple smaller rolls according to production requirements. With roll diameters reaching 1000 millimeters, large paper rolls can be processed efficiently without frequent material replacement.

Nonwoven Fabric

Nonwoven materials used in hygiene and industrial products are often supplied in wide roll formats. These rolls must be slit into smaller widths before entering converting lines. The slitting machine processes nonwoven materials while maintaining stable tension and cutting accuracy. High speed processing ensures efficient preparation of nonwoven rolls for downstream manufacturing.

Hygiene Materials

Disposable hygiene products use multiple flexible materials that are supplied in large roll formats. These materials must be slit into specific widths before product assembly. The slitting machine processes these materials through precise cutting units and rewinds them into multiple finished rolls. Continuous roll slitting ensures stable supply of converted materials for hygiene product production lines.
