One-Step Prepreg Narrow Slitter

The TT-FCR (100~320)-(4~48) prepreg narrow slitter is a specialized machine designed for precision slitting and automatic coil winding of prepreg materials. The complete system consists of prepreg unwinding, splicing, pre-slitting, narrow slitting, non-slit rewinding, release liner rewinding, pull-roll, yarn-separating, edge trim collection, PE film narrow unwinding, finished-product coil winding, online width inspection, and electrical control units. It is suitable for slitting thermoset prepreg and thermoplastic prepreg into narrow tapes, followed by film lamination and coil winding, providing high-precision narrow-width feedstock for downstream processes such as automated fiber placement and filament winding. It is widely used in UAV, marine, automotive and rail transit, wind turbine blades, petrochemical, and other fields for narrow-tape placement, pressure vessels, and pipe winding.

·Applicable Materials: Thermoset prepreg, thermoplastic prepreg (carbon/glass fiber prepreg tapes)
·Slitting Width: 3.175 – 12.7 mm (any specification, e.g., 3.175, 6.35, 12.7 mm, etc.)
·Slitting Accuracy: ±0.125 mm
·Slitting Width (minimum): 3.175 mm with accuracy ±0.125 mm
·Number of Rewind Heads: 4 – 48
·Winding Patterns: Spiral, parallel, positive taper (trapezoidal), etc.

·Ultra-High Precision Slitting
Slitting width ≥3.175 mm (any specification). Micron-level high-precision grinding blade set ensures accuracy of ±0.125 mm. Equipped with blade depth detection system for real-time display of cutting depth and zero position.
·Dual-Servo Precision Rewinding
Independent servo control for both winding and traversing. Each head has its own servo motor, can be started individually or simultaneously. Traverse width and winding pattern (spiral/parallel/positive taper) are freely set via HMI. Tension control uses floating-rod constant tension with high stability and accuracy.
·Intelligent Operation & Data Management
PLC + 15-inch HMI with high digitalization. Recipe management function allows one-click download of control parameters (tension, speed, length, winding pattern, etc.). Supports multi-user authority management (operation interface, data monitoring, system management, debugging/maintenance, fault code analysis).
·Modular Expandable Design
PE film narrow unwind and finished-product coil winding stations can be freely expanded according to actual needs. They can be started simultaneously or independently, adapting to various application scenarios.
·Comprehensive Auxiliary Functions
Equipped with splicing unit (heating & pressing, temperature ≤80°C / accuracy ±2°C) for seamless prepreg tape joining to reduce threading. Online width/defect inspection system (high-definition camera vision, detects PE film debris, fuzz, adhesive tape, and other foreign matter, displays real-time width of each strip). Infrared laser pointer on unwinding for precise positioning. Multiple emergency stop buttons and audible/visual alarms for safe operation.
