卷式压延机 WSL

卷对卷卷对卷工业

Overview
The Crest WSL is a high-precision industrial slitter rewinder and optional inline laminator engineered for tension-sensitive conversion of flexible films, specialty foams and laminates. It integrates pneumatic circular slitting, loop-controlled centre winding and an advanced inline lamination station to enable single-pass or dual-pass workflows without material deformation, telescoping or edge defects.

Key features

• Pneumatic circular knives for ultra-clean, burr-free slitting
• Deformation-free, loop-controlled centre winding for stable roll density
• Single-pass and dual-pass lamination capability (integrated laminator optional)
• Inline Corona surface activation for improved adhesive anchoring (optional)
• Precise dual-roller nip system to prevent micro-air inclusions
• Heavy-duty platform for jumbo rolls and rapid operator-friendly changeovers

Primary capabilities

• Accurate, clean edge quality using pneumatic circular knives configurable with or without overlap
• Deformation-free winding of compressible substrates via loop-controlled tension
• Single- and dual-pass workflows: foam activation and adhesive coating (Pass 1) followed by backing application and final slitting (Pass 2)
• Support for in-line Corona treatment to microscopically activate non-porous surfaces prior to lamination

PASS 1: Foam activation & adhesive coating
The raw specialty foam is unwound and passed through the Corona Treatment Unit to increase surface energy, then a high-tack adhesive layer is laminated under precise nip pressure to guarantee a durable bond.

PASS 2: Backing application & final slitting
The adhesive-laminated foam from Pass 1 is fed back into the line; the plastic backing material is laminated onto the adhesive side (Corona off) and pneumatic circular knives perform final precision slitting to customer widths.

Suitable materials

• Technical foam laminates (examples: ProBAK®, Softprint®, Cushion-Mount™)
• Flexographic backing and compressible foams
• Polyester (PET) and PVC plastic backing films
• High-tack self-adhesive laminates
• Protective films and release liners

Best suited for

• Converting delicate, compressible foams requiring exact tension control to avoid structural deformation
• High-precision slitting without adhesive bleeding or fraying
• Dual-pass lamination workflows for foam activation followed by backing application on a single platform
• Heavy-duty production handling jumbo rolls up to ø1200 mm and heavy master rolls
• Operations requiring rapid, toolless changeovers between 3" and 6" cores

Performance benefits

• Maximized yield and minimized scrap through precise slitting and responsive loop tension control
• Zero-defect composite quality via stable centre winding and dual-roller lamination to eliminate micro-air inclusions
• Heavy-duty industrial uptime with operator-friendly knife positioning and fast changeovers

Frequently noted options / customisation

• Optional inline laminating unit to combine lamination, slitting and rewinding in one workflow
• Adjustable working widths (standard configurations up to 1650 mm and beyond)
• Advanced edge-guiding systems and custom loop-controlled tension configurations to match line requirements
