Paper Slitter Rewinder

The Paper Slitter Rewinder is a broad-format roll processing unit created for packaging and paper manufacturing workshops. It can cut various industrial base papers such as kraft stock, adhesive sheets and coated paper, alongside flexible plastic materials including PET, PVC and vacuum aluminized film. It supports raw materials with thickness between 12μm and 300μm. Its standout advantage lies in handling wide master rolls in bulk production, which makes this Paper Slitter Rewinder highly popular among large-scale processing factories.

The whole framework is fabricated with thickened steel panels, bringing much higher weight-bearing performance than regular slitting gear. This Paper Slitter Rewinder supports a maximum feeding width of 1600mm, and the parent paper roll can reach a 1200mm outer diameter with a single roll weight above 1000kg. The built-in pneumatic automatic loading mechanism removes heavy manual roll lifting work and shortens production halt time during material switching. Its unwinding unit is fitted with a 3-inch key air shaft controlled by magnetic powder tension parts, plus a linear guide photoelectric correction system with a ±75mm adjustment range to fix material drifting instantly. The dimensional error after cutting stays within 0.1mm, producing tidy reels without burrs, uneven width or edge warping. An 11kW motor powers the traction assembly; chrome steel driving rollers and air cylinder-operated rubber pressing rollers avoid stretching and wrinkling on thin lightweight paper to maintain steady material transfer.

Ten air-pressure cutting blades come as standard for this Paper Slitter Rewinder, with safety housings mounted on cutter bases to protect operating staff. Clients may purchase extra circular blades and auto knife positioning kits to match different paper weight requirements. Two segmented air expansion shafts of 76mm diameter are arranged in upper and lower layers for alternating rewinding, and the maximum diameter of finished rolls can hit 600mm. A pneumatic manipulator assists winding work, and the single-side rotary unloading design allows one staff member to move 350kg finished reels with less physical effort.

Intelligent digital control relies on Siemens PLC and MCGS color touch screen for the Paper Slitter Rewinder. Operators only need to fill in basic parameters like paper thickness, web width and running speed, and the equipment will automatically calculate suitable tension values for unwinding and rewinding sections. It is equipped with an automatic length counter and residue auto-stop feature, with measurement deviation limited to 1 meter per kilometer. Separate tension parameters for thin and thick paper reduce material waste caused by paper rupture and loose winding layers.

Major core components adopt well-known industrial brands, including Delta inverters, NSK bearings and Schneider electrical parts. A supporting centrifugal fan discharges leftover paper scraps from the side of the machine to keep the processing area clean. The equipment speed can be adjusted from 0 to 200 meters per minute, with total power consumption of 16kW and compatibility with 380V three-phase factory power. With overall dimensions of 3776×2630×1620mm and a total weight of roughly 2700kg, it maintains stable operation without structural deformation during long-hour continuous production. A complete maintenance toolkit, wear-resistant spare pieces and official operation handbook are supplied together to simplify daily servicing. With strong wide-format capacity and automated operation, this multi-purpose Paper Slitter Rewinder serves as essential production equipment for paper factories to lift productivity and stabilize finished product standards.
