PSA Allslit Kompakt Fully Automatic Slitting and Rewinding Machine

Overview

The PSA Allslit Kompakt is a fully automatic slitting and rewinding machine engineered for high-precision, high-throughput conversion of flexible roll materials in packaging, industrial film, and specialty paper production environments. Based on modular mechatronic architecture and designed in Germany, the system implements closed-loop tension control, servo-driven web guidance, and real-time diameter tracking to ensure consistent slit edge quality, minimal waste, and repeatable rewind integrity across diverse substrate families. Its compact footprint—achieved through integrated unwind stands and vertically stacked dual rewind shafts positioned at ergonomic operating height—optimizes floor space without compromising mechanical rigidity or thermal stability. The machine operates under deterministic motion control logic compliant with IEC 61800-3 (adjustable speed electrical power drive systems) and integrates seamlessly into Industry 4.0-capable production lines via OPC UA interface.

Key Features

• Dual-stack rewind configuration with independent servo-controlled shafts, enabling simultaneous winding of two finished rolls at identical or differential speeds and tensions
• Integrated pneumatic unwind stand with automatic center-spread expansion chucks, load-cell-based tension feedback, and dancer roller compensation for dynamic web tension regulation (±0.5% setpoint accuracy)
• Modular slitting station supporting five distinct cutting methodologies: guillotine shear (for clean, burr-free edges on films and foils), score cut (for controlled delamination of laminates), flying cut (for continuous operation during web motion), pressure cut (for low-force separation of coated papers), and tear cut (for pre-perforated or weak-layer substrates)
• Optional robotic auto-splice and auto-eject system compliant with ISO/IEC 15408 EAL2+ functional safety requirements, reducing manual intervention and enabling unattended shift operation
• Touchscreen HMI with multilingual UI (EN/DE/FR/ES), built-in diagnostics, and configurable recipe management for rapid changeover between material types and width configurations
• Structural frame fabricated from stress-relieved cast iron with vibration-damped mounting, ensuring long-term geometric stability under sustained 600 m/min line speeds

Sample Compatibility & Compliance

The Allslit Kompakt accommodates a broad spectrum of flexible web materials conforming to ASTM D882 (tensile properties of thin plastic sheeting), ISO 5628 (paper and board tensile testing), and EN 13924 (aluminum foil for packaging). It supports substrates ranging from 12 µm PET film to 300 g/m² corrugated linerboard, including heat-sensitive metallized films, pressure-sensitive adhesives, and multi-layer barrier laminates. All electrical components meet CE marking requirements under the Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU. Optional validation packages support IQ/OQ documentation per GMP Annex 15 and FDA 21 CFR Part 11-compliant electronic record audit trails when paired with PSA’s certified MES integration module.

Software & Data Management

Control firmware runs on a real-time Linux kernel with deterministic scheduling, synchronized to encoder-based position feedback at 1 MHz sampling rate. The embedded software suite includes: (1) SlitEdge™ quality analytics—monitoring lateral deviation, edge roughness index (ERI), and taper accumulation in real time; (2) Predictive maintenance scheduler using bearing temperature, motor current harmonics, and web tension variance as failure indicators; (3) Secure data export in CSV, XML, and PDF formats with timestamped digital signatures; (4) Role-based access control (RBAC) with LDAP/Active Directory integration for multi-site fleet management. Historical process data is retained for ≥18 months on-board and can be exported to cloud-based SCADA platforms via TLS 1.3 encrypted MQTT.

Applications

This system serves critical functions in converter operations requiring stringent dimensional repeatability and regulatory traceability—including medical device packaging (ISO 11607-2 compliant pouch slit width verification), food-grade laminate production (EU Regulation No. 10/2011 migration testing sample preparation), battery separator film slitting (Li-ion cell anode/cathode layer uniformity control), and label stock manufacturing (UL 969-certified die-cutting precursor processing). Its ability to maintain ±0.15 mm slit width tolerance across 2000 mm webs at full speed enables qualification for automotive interior trim backing, aerospace composite prepreg carrier release liners, and pharmaceutical blister foil lamination workflows.

FAQ

What safety certifications does the Allslit Kompakt carry?

It complies with CE, UL 508A, and meets ISO 13857 guarding distance requirements for accessible hazardous zones.
Can the machine handle static-sensitive materials such as ESD films?

Yes—optional ionized air nozzles and grounded conductive rollers are available to maintain surface resistivity below 10⁹ Ω/sq per ANSI/ESD S20.20.
Is remote diagnostics supported?

Standard Ethernet/IP and optional 4G LTE modem enable secure remote monitoring, firmware updates, and technician-assisted troubleshooting via encrypted VNC session.
How is tension calibrated during commissioning?

Factory calibration uses NIST-traceable deadweight loading on load cells; field recalibration is performed using certified torque wrenches and reference tension meters per ISO 2411.
Does the system support integration with ERP/MES platforms?

Yes—OPC UA server implementation provides read/write access to job status, material consumption, downtime codes, and quality KPIs (OEE, PPM defect rate, first-pass yield).
