Surface Slitter Rewinder

In wide-web converting operations, the jumbo slitter rewinder is a cornerstone machine. It handles both paper and film substrates with ease, making it a natural fit for high-volume production in packaging plants, commercial print shops, and composite material factories.

Material versatility is one of its strong suits. On the paper side, it takes on kraft paper, masking tape base, self-adhesive label stock, coated art paper, and glossy wrapping grades. On the film side, it runs PET, OPP, PE, PVC, laminates, and metallized films without trouble. Substrate thickness can range from 12 microns up to 500 microns – so whether you're dealing with flimsy thin webs or sturdy thick sheets, this single machine covers the ground that would otherwise require several separate units. That alone can save a sizable capital outlay.

Where this unit really stands out is its generous width capability. With a maximum working width of 2700 mm, it can slice through full-width master rolls in a single pass. Slitting accuracy holds steady at ±0.1 mm, delivering clean edges – no burrs, no cracks – that satisfy even premium-grade quality requirements. Running speed is infinitely adjustable from 10 to 500 m/min: dial it down for delicate, high-end paper finishes, or crank it up for rapid throughput on bulk orders. The unwind section accepts rolls up to 1700 mm in diameter and 1500 kg in weight, while the dual-station rewind handles finished rolls up to 1200 mm. Big parent rolls mean fewer changeovers and less idle time, directly feeding into higher output. The main frame is made from 60-mm thick steel plate, welded into a single rigid structure that resists vibration and stays true even under round-the-clock full load. At nearly five tonnes, the machine runs quietly with low wear, easily outlasting narrower, less robust alternatives in 24/7 operation.

On the automation front, this slitter rewinder is built for operator convenience. The unwind station uses a single-position hydraulic shaftless chucking system, compatible with both 3-inch and 6-inch air shafts, and includes a pneumatic splicing table to speed up roll preparation and web joining. The pull-roll assembly is driven by an 11 kW servo motor, with rubber nip rollers paired with chrome-plated steel rolls, all actuated by air cylinders to keep the web tracking straight and stable. The slitting section comes with ten standard air-knife holders, manually adjustable with minimal setup hassle and very low trim waste. Rewinding is powered by two 15 kW servo motors, and a hydraulic manipulator works together with a discharge trolley to automatically offload finished rolls – maximum weight 750 kg – drastically cutting manual handling, reducing labour, and eliminating lifting-related safety risks.

Intelligent control is another major selling point. The entire system is orchestrated by a Siemens PLC (German-built), with a high-resolution touchscreen from Kunlun Tongtai. The interface is so straightforward that even novice operators can get up to speed after just a brief orientation. Multiple built-in protective routines take care of themselves: automatic stop when the unwind roll runs out, decelerated stop at the preset cut-length, and self-adjusting tension control for both unwinding and rewinding throughout the run. The operator simply keys in basic data – material thickness, width, and roll diameter – and the system works out the best operating parameters on its own, saving endless manual tweaking. A BAT photoelectric edge guide with ±75 mm correction travel continuously tracks and corrects web wander, preventing telescoped or uneven rolls. A centrifugal blower blows trim waste and dust sideways out of the machine, keeping the floor clean and stopping debris from building up and causing faults.

All vital components come from top-tier global suppliers: Rexroth drives, NSK bearings, Schneider low-voltage gear, Autonics proportional valves, and a complete set of air knives. This high-end parts list translates into long service life, few breakdowns, and low ongoing maintenance costs. Every machine ships with a full toolkit, spare wear parts, levelling pads, and a detailed operation manual – so after-sales support is never a worry. In short, this jumbo slitter rewinder offers broad width, reliable precision, a high degree of automation, wide material adaptability, rugged construction, and straightforward upkeep – all at a price-performance ratio that makes it a smart choice for paper and film converters looking to upgrade quality, expand capacity, and trim overall production expenses.
