High-Speed Laser Perforation

Laser perforation is one of the preferred perforation technologies for cigarette tipping paper. With its PerfoLas systems, ROFIN is a market and technology leader in this application area. Without the use of components like beam switches, masks, needles,choppers or perforation electrodes, the contact-free laser perforating process offers optimum hole quality and process control. Modifying production parameters is a breeze, so changing market requirements or future law restrictions can be met with great flexibility and without additional investments.

Unique Beam Multiplexer for Maximum Performance and Accuracy

Unique Beam Multiplexer for Maximum Performance and Accuracy

The core technology for perforating, developed by ROFIN, is a unique beam distribution mechanism, the beam multiplexer. A rotating polygon mirror delivers up to 16 perforation beams which can perforate up to 450.000 holes per second. Hole densities vary between 5 and 50 holes per cm and row. For maximum precision the position of each perforation head can be adjusted in steps of 0,01 mm. Processor-controlled winding motors guarantee a speed uniformity better than +/- 0,5% for web speeds between 50 and 700 m/min. With this extraordinary accuracy the standard variation of porosity reaches the lowest levels available.

Reliable Quality Assurance with Visual Porosity Measurement

Reliable Quality Assurance with Visual Porosity Measurement

Rising quality standards and stricter laws require substantially improved quality assurance systems. With the introduction of VPM – a device measuring the porosity of perforated tipping in Coresta Units in real-time at max. 700m/min, ROFIN provides an extremely reliable quality assurance tool for laser and electrostatic perforation systems. ROFIN’s patented technology  yields rich information: Porosity per hole, dimensions of the holes and the overall porosity of the perforation zone are calculated and displayed. Since the system calibrates itself, the results are extremely accurate.
