All in One Web Guiding Control System for Any Printing Machinery

Offset Pivot Guide System Overview

The web guide system is an automatic control system that detects and corrects the positional deviation of thin materials during high-speed conveying. It features automatic detection, tracking, and correction functions for materials such as paper, film, adhesive tape, aluminum foil, and strip steel to ensure perfectly neat winding and slitting.

Edge Position Controller Features

The Servo Edge Position Controller EPC-A10/LPC-A12 utilizes a high-speed 32-bit CPU and DC servo driver with a no-overshot integral variable PI adjustable algorithm for rapid response and high precision.

• Supports Edge-following, Line-following, and Center-alignment modes.
• Compatible with photoelectric, ultrasonic, and CCD sensors.
• Intelligent parameter detection; minimal sensor correction needed.
• Automatic travel measurement without mechanical limit switches.
• 0.5msec super-speed response time.
• 12bit AD sampling, 700,000 times per second.
• FIR digital filter for strong anti-interference capability.
• DC servo motor driving a high-precision ball screw.
• Power-down memory for all system parameters.
• Stores 10 groups of material parameters for quick switching.
• Multi-language support: Simplified/Traditional Chinese, English.
• Supports Modbus and PLC/Human-computer networking control.

This correction system is essential for maintaining neat and consistent coil alignment during spraying, printing, punching, laminating, and slitting. It is widely used across multiple sectors including steel, corrugated paper, textiles, printing, labeling, plastic film, building materials, cables, rubber, and non-woven processing.
