Hunkeler HL6 unwinder

Hunkeler HL6 laser perforator

The Hunkeler HL6 is a high-performance unwinder designed for use in digital printing and paper processing systems. Its typically used in commercial printing environments where large volumes of paper need to be fed into printing or finishing machines. The HL6 is known for its reliability, precision, and speed, making it suitable for demanding production environments. Its often integrated into production lines alongside other printing and finishing equipment to streamline workflows and increase efficiency.

Purpose

The Hunkeler Laser module HL6 produces precise perforations, cut-outs or kiss-cuts of any forms in 1-up and 2-

up mode. The main applications are in transpromo- and security-printing. Deposit slips, coupons, reply cards and

labels can be manufactured individually without pre-processed paper. Security relevant documents can be

prevented from counterfeiting by adding symbols, texts or numbers by laser.

Method of operation

The printed continuous paper is fed to the module in offline mode. Jobs (laser patterns) created by the user are

loaded to the module via the integrated PC. The relevant laser pattern is retrieved via a data matrix code and executed

accordingly. There are hardly any limits to flexibility in terms of job and laser pattern variations.

Special technical features

The processing parameters and corrections can be set easily by means of the large-sized color display. Laser images

are generated and managed using the separate Laser Editor software. The modular concept enables individual

equipment of the module with one or two laser heads of different power.
