High-speed reel-fed envelope-making machine completely rebuilt and upgraded by Curtius Technologies to increase production output (up to 1200 epm) while reducing maintenance costs.

 

Fast and Efficient installation

The reconstructed W+D 102 is fitted with a new motor, AC drive and 4 upgraded electrical boxes attached directly to the main sections of the machine, for a fast and easy installation. No cumbersome onsite rewiring needed.

Remote control software installed in the machine allows engineers to troubleshoot the machine from the company’s headquarters in Atlanta, thus minimizing machine downtime and maintenance costs.

 

Improved production throughput

The machine is retro-fitted with a new high-speed patcher, which applies the glue onto the window film instead of the paper at speeds up to 1200 epm, thus reducing significantly the risk of glue projections and costly paper jams. The improved patcher unit also allows the use of window film thinner than 30 micron for a much more cost-effective and eco-friendly operation than traditional patchers.

The new efficient Infrared Drying Technology used on the W+D 102 directly targets the glue deposited on the envelope-closing-flap instead of the surrounding air or paper, which improves the overall envelope-drying time and reduces significantly the energy consumption of the machine (from 60 kW to 18kW) for a more cost-effective and eco-friendly operation.

A new upgraded belt transmission system coupled with harmonic drive gearing is installed throughout the machine (in the scoring, separating, staggering as well as delivery sections), which allows “on-the-run” adjustment, reducing set up time and maintenance costs.

Easy and cost-effective operation

Two new Touchscreens located in the window cutting section and in the delivery section allow operators to centrally control all functions of the machine including: regulating the temperature of the Infrared drying system, changing batch parameters and options, controlling the speed of the machine or locating and trouble-shooting in real time paper jams to minimize machine downtime.

With the new Panel Cutter (PC) Automatic Kick-out, there is no need to reset the panel cutter manually anymore; the new automated system deactivates the PC when the machine is stopping and engages the PC and the patch automatically once the machine reaches a predetermined speed.

A tension control system continuously adjusts the tension on the web with the use of two-servo motors, thus preventing the web from breaking, especially with large windows.

Improved print quality

The installation of a doctor blade system guarantees high resolution printing quality even at high speeds.

 

A new upgraded belt transmission is installed in the printing units, which improves registration and printing quality.
