Prepreg Pre-Slitter (Wide Slitter)

The TT-F-YY (1000~1600) prepreg wide slitter is a dedicated machine designed for wide-web rewinding and slitting of thermoset prepreg materials. The complete system consists of prepreg unwinding, release liner/PE film stripping and rewinding, slitting, pull-roll, edge trim collection, finished-product rewinding, and electrical control units. It is suitable for slitting wide prepreg into medium-width tapes (≥50 mm), providing high-precision wide-width feedstock for downstream automated tape laying (ATL) processes, and can also serve as a pre-slitting step before narrow slitting. Widely used in UAV, automotive lightweighting, wind turbine blades, rail transit, and other fields for prepreg wide-tape preparation.

·Applicable Materials: Thermoset prepreg, thermoplastic prepreg (carbon/glass fiber prepreg tapes)
·Slitting Width: ≥50 mm (any specification)
·Slitting Accuracy: ±0.125 mm
·Prepreg Unwind Width: 1000 – 1600 mm (depending on model)
·Rewinding Method: Dual differential-shaft center winding
·Rewind Diameter: Φ600 mm
·Core Inner Diameter: 76 – 305 mm (compatible with multiple sizes)

·Ultra-High Precision Slitting
Slitting width ≥50 mm (any specification) with accuracy ±0.125 mm. Optional pneumatic or mechanical circular knives produce clean, burr-free edges, meeting the stringent precision requirements of automated tape laying (ATL).
·Differential-Shaft Center Winding
Uses differential shafts with asynchronous servo motors and vector inverter taper tension control, effectively eliminating uneven tightness caused by material thickness variation, ensuring consistent tension and neat edges for every roll.
·Unique Follow-Up Unwinding & Web Path Design
Effectively prevents delamination during prepreg slitting, ensuring the material remains stable and free from interlayer separation during the process.
·Flexible Release Liner/PE Film Stripping
Independent stripping and rewinding unit (asynchronous servo motor + vector inverter taper control). Thermoset prepreg can be slit directly or after removing the release liner/PE film, adapting to different process requirements.
·Intelligent Operation & Data Management
PLC + 15-inch HMI for centralized control. Fully automatic constant tension for both unwind and rewind, with high-precision servo edge-guide for neat edges. Automatic length counting with alarm for roll change, and automatic parameter memory after power-off, making operation convenient and intuitive.
·Heavy-Duty Large-Roll Design
Unwind load capacity of 800 kg, and unwinding/rewinding diameter up to 600 mm, accommodating large prepreg rolls, reducing roll change frequency, and improving productivity.
·Compatible with Multiple Core Sizes
Supports core inner diameters of Φ76 mm, Φ254 mm, Φ305 mm, and others, adapting to raw materials and finished rolls from different manufacturers.
