Web Direction Series Laser Micro-Perforation Machine

Designed for a Variety of Processes

WD (Web Direction) Series machines are utilized for a variety of processes, including web direction laser scoring or micro-perforating. Laser scores can be continuous or intermittent dashes. Micro-perforation hole sizes from 50 µm - 150 µm (.002 in - .006 in) can be produced, depending on material type. The laser perforation machine has multiple setup options with processing heads from one to sixteen. Using Preco’s proprietary compression technology will allow you to produce consistent round holes at speeds up to 457 m/min (1500 ft./min) depending on film type and thickness.

The WD Series machines can be designed and integrated into production lines such as laminators, extruders or can be set up off-line on a rewinder or slitter. Systems are adaptable with web widths up to 1600 mm (62.99′′).

Features & Benefits

On-the-fly control of the laser scoring/perforating process based on recipe parameters, instantaneous web speed, repeat pattern, photo-eye sensor, etc., allows accurate scoring/perforating during ramp-up and ramp-down. The controller compensates web speed fluctuation during the entire run resulting in quality product and substantial waste reduction.

Reduces set-up time; unify production from operator to operator.

Provides added flexibility in scoring different film materials

On-the-job feedback including laser process parameters, web speed and web length

Precision control of laser energy, unique to Preco (Optional)

Easily clean lens and mirrors without causing beam misalignment

Quick and accurate positioning of score or perforation locations

Precise positioning of focal point and ability to handle different film thickness

Eliminates scrap caused by overpowering of material at slower than normal processing speeds.
