1600mm Paper Roll Rewinding Slitter Machine | High Speed Paper Slitting Rewinder

1. Product Overview

The 1600mm Paper Roll Rewinding Slitter Machine is a professional industrial-grade paper converting equipment tailored for large-width paper roll slitting, trimming, and precise rewinding. Designed to meet the high-efficiency and high-precision production demands of the modern printing, packaging, and paper processing industries, this machine perfectly solves the problems of irregular cutting edges, uneven winding, low output, and frequent roll replacement in traditional paper processing equipment. With a scientific mechanical structure and intelligent control system, it supports mass continuous production of various paper materials, becoming core processing equipment for paper factories, packaging enterprises, and printing manufacturers.

This slitter rewinder adopts a heavy-duty integrated steel frame structure, which features stable operation, strong shock resistance, and long service life. It supports a maximum processing width of 1600mm, covering most wide-format parent paper rolls on the market. Equipped with an electromagnetic speed regulation system and full-process constant tension control technology, the machine realizes stable speed adjustment from low speed to high speed, effectively avoiding paper stretching, wrinkling, deviation, and telescoping during processing. The whole machine realizes automated operation from paper loading, slitting, tension adjustment to rewinding and scrap collection, greatly reducing manual intervention and production labor costs.

In terms of processing efficiency, the equipment achieves a maximum operating speed of 300 meters per minute, which is far higher than traditional ordinary slitting machines. While ensuring high-speed operation, it strictly controls slitting accuracy and winding uniformity, realizing high-quality and high-output integrated processing. It is compatible with multiple cutting tools including razor blades, shear cutters, and score-cutting tools, which can be flexibly switched according to paper gram weight, material hardness and edge finish requirements, meeting diversified slitting specifications of different customers.

2. Core Features & Advantages

2.1 Wide Application & Flexible Processing Range

The machine supports a paper gram weight range of 60-700g, covering lightweight newsprint, medium-weight coated paper, kraft paper, and heavy-duty cardboard. The jumbo roll processing width ranges from 40mm to 1600mm, with a maximum unwinding width of 1200mm and a finished roll diameter of up to 1200mm. It can complete multi-specification narrow roll slitting in one pass, realizing flexible conversion of multiple production specifications and meeting customized processing needs of different industries.

2.2 Precise Tension Control & High Winding Quality

Equipped with an advanced full-process tension control system and intelligent torque control device, the equipment maintains constant tension in the whole process of unwinding, slitting and rewinding. The air pressure stalk involution winding method ensures tight and uniform winding of finished paper rolls, effectively reducing air entrapment inside the rolls. The precise core alignment design guarantees the concentricity of finished rolls, eliminates eccentric winding defects, reduces material waste rate, and improves product yield.

2.3 High Efficiency & Labor Saving Operation

Adopting pneumatic paper loading mode, the machine realizes automatic paper feeding, saving manual loading time and improving feeding efficiency. The electromagnetic speed adjustment system supports stepless speed regulation of 0-300m/min, with stable speed transition and no jitter. Equipped with 21 sets of high-precision blade groups, it can complete multi-channel slitting at one time, avoiding repeated processing. The built-in automatic scrap removal system independently collects trimming waste during operation, ensuring a clean production environment and improving continuous production capacity.

2.4 Durable Structure & Intelligent Humanized Design

The whole machine is made of heavy-duty thickened steel plate and high-precision mechanical components, with firm structure, strong wear resistance and low failure rate, realizing long-term stable continuous operation and reducing daily maintenance costs. The intuitive HMI human-machine interface supports one-click parameter setting, real-time operation data monitoring and automatic fault diagnosis, which is simple to operate and reduces the technical threshold for workers. In addition, it is equipped with emergency stop device, safety protective guards and sensor interlock protection functions, fully complying with international industrial safety production standards to ensure operator safety.
