SHWS-A Standard Horizontal Shaftless Unwinding and Slitting Machine | Heavy-Load Paper, Film and Foil Roll Slitter Rewinder
The SHWS-A Standard Horizontal Shaftless Unwinding and Slitting Machine is designed for large-roll paper, film, foil and nonwoven slitting. It combines heavy-load shaftless unwinding (1000KG capacity), Siemens PLC and servo drive, and 3-6 inch core options to improve slitting, cutting and rewinding consistency while reducing material waste and operator workload. Widely used in paper product processing, printing and packaging, and nonwoven industries.
Performance and Features
Precise Intelligent Control
Equipped with a Siemens PLC control system integrating automatic meter counting, residual material detection and alarm, and automatic shutdown at preset length. The system monitors the entire operation in real time, triggering alarms and automatic shutdown when materials run low or malfunctions occur, reducing material loss and improving slitting accuracy.
Convenient Loading and Excellent Load Capacity
An independent shaftless loading system mounted on the same side of the main unit eliminates manual roll handling for simple and efficient operation. Capable of bearing over 1000KG, it is compatible with rolls in various specifications, greatly reducing labor intensity and boosting loading efficiency.
Labor-Saving and Efficient Unloading
Fitted with a dedicated single-side swing-out unloading arm. After the machine stops, finished rolls are automatically pushed onto the arm without manual work, streamlining the unloading process and suiting large-scale continuous production.
Accurate Web Guiding for Superior Quality
The high-sensitivity automatic web guiding system corrects material deviation in real time even when raw material has uneven edges. It prevents web wandering, ensures precise slitting, and delivers finished rolls with uniform dimensions and neat edges to optimize product quality.
Powerful Servo Drive
Adopting dual or triple servo motor drive, the system features fast response and smooth, jitter-free operation. It perfectly coordinates the speed of slitting and rewinding, keeping the entire process steady and deviation-free.
High-Speed Operation for Higher Productivity
The maximum operating speed reaches 200 m/min. While maintaining high slitting and rewinding precision, it effectively improves productivity and fully meets the demands of mass roll material processing.
Wide Compatibility and Customizable Specifications
The unwinding section supports 3-6 inch air expanding shafts, and the rewinding section comes standard with a 3-inch slip shaft with custom sizes available on request. The standard maximum unwinding diameter is 1500mm, and the rewinding diameter ranges from 600mm to 800mm. Machine width can also be customized to fit diverse production scenarios.
Thoughtful Customization Service
Tailored solutions covering machine width, rewinding diameter, shaft specifications and more to meet customers' actual production needs. The equipment adapts to various processing scenarios and works with roll materials of different sizes and materials.
