Product overview
The high-precision slitter rewinder & laminator for specialty foams and films. The Crest WSL is custom-built for tension-sensitive converters executing complex single-pass and multi-pass laminating workflows. By integrating pneumatic circular slitting, specialized loop-controlled center winding, and an advanced inline lamination station, it manages slitting, rewinding and lamination with minimal material deformation or telescoping.

Core capabilities
The WSL supports inline Corona surface activation for adhesive anchoring, precise nip roll adjustments and loop-controlled tension to deliver clean edges and uncompromised roll quality across multi-stage production.

Key features

• Pneumatic circular knives (crush-cutting) for ultra-clean, burr-free edges
• Loop-controlled center winding for deformation-free master roll converting
• Optional integrated inline laminator to combine lamination, slitting and rewinding
• Inline Corona treatment unit for surface activation (used in Pass 1)
• Dual-roller nip system to prevent micro-air inclusions and ensure homogeneous laminated rolls
• Rapid, operator-friendly knife changeovers and flexible shaft handling for 3" and 6" cores
• Heavy-duty platform engineered for jumbo rolls and continuous industrial uptime

Where do you need it for?

• 01 / FOAM & FLEXIBLE CONVERTING — Deformation-free master roll converting of advanced foams, high-tack adhesive laminates and technical films; specialized loop-controlled tension prevents squeezing of compressible substrates.
• 02 / HIGH-PRECISION SLITTING — Accurate and clean edge quality for industrial converters, pneumatic circular knives for precise web alignment with or without overlap and fast knife changeovers.
• 03 / MULTI-PASS LAMINATION & CONVERTING — Efficient dual-pass workflows: Pass 1 activates foam via Corona and applies adhesive; Pass 2 applies plastic backing with the dual-roller nip system and performs final precision slitting.

One platform — dual-pass workflow
The WSL is engineered to execute the full flexo backing production cycle in two efficient passes on a single footprint, eliminating the need for multiple machines.

Process — PASS 1: Foam activation & adhesive coating
The raw specialty foam is unwound, passed through the Corona Treatment Unit to microscopically activate its surface, then laminated with a high-tack adhesive layer under precise nip pressure to guarantee a strong bond.

Process — PASS 2: Plastic backing application
The adhesive-laminated foam from Pass 1 is reintroduced to the line; the machine applies the plastic backing (Corona switched off) and the pneumatic circular knives slit the final laminate to exact customer widths while maintaining roll integrity.

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
• Various other tension-sensitive specialty materials

When to choose the WSL

• When converting delicate, compressible foams requiring exact tension control to prevent structural deformation.
• When 100% bubble-free lamination is needed; the dual-roller sets and precise nip control prevent micro-air inclusions.
• When clean, burr-free edges are essential, achieved by accurately aligned pneumatic circular knives without adhesive bleeding or fraying.
• When processing jumbo master rolls up to ø1200 mm and 500 kg that require heavy-duty center winding and loop control.
• When a dual-pass lamination workflow (foam activation then backing application) is required on a single, versatile platform.
• When frequent, rapid, toolless changeovers between 3" and 6" cores are necessary for short-run flexibility.

Why it performs

• Maximized yield, minimized scrap — pneumatic knives and responsive loop tension reduce edge waste and misalignments while preventing foam compression and telescoping.
• Zero-defect composite quality — stable center winding and dual-roller lamination produce homogeneous, tightly wound rolls suitable for demanding downstream printing processes.
• Heavy-duty industrial uptime — operator-friendly positioning, rapid-access changeovers and flexible shaft configurations support high productivity and short-run agility.
