One of the largest suppliers of envelopes in Australasia, just acquired a  Winkler + Dünnebier 102 machine completely rebuilt and upgraded by Curtius Technologies Inc.

The machine was tested at Curtius headquarters in Atlanta, at almost 1200 envelopes per minute, in the presence of renowned envelope manufacturers. This major milestone  positions Curtius as the only truly independent alternative in the envelope industry.W+D 102 rebuilt and upgraded running 1200 epm

Easy and cost-effective operation

The reconstructed W+D 102 was 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 on site rewiring needed during installation.

Two new touch screens 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.

The new Panel Cutter (PC) is fully automated. This new system deactivates the PC when the machine is stopping and engages the PC and the patch automatically once the machine reaches a predetermined speed, allowing the operator to start the machine from any location.

A tension control system continuously adjusts the tension on the web with the use of two-servo motors, thus preventing the web from breaking and saving time and money.

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 12 kW) for a more cost-effective and eco-friendly operation.

Reduce maintenance cost and set up time

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.

A major American producer of office supplies recently acquired for their plant in Mexico a Halm Super Jet press fully reconditioned by Curtius Technologies Inc. This dual feed, two color offset perfector press, which was completely rebuilt and installed by Curtius Technologies technicians on April 2012, can print on both sides of blank mailing envelopes in one pass at speeds up to as 30,000 envelopes per hour on 2up. Its dual standard feeders make it possible to run a large variety of envelope sizes up to 9” x 12” when perfecting.

This new installation marks another success for the versatile Halm Super Jet press, and confirms Curtius Technologies Inc. as an expert in rebuilding and upgrading what’s possibly the fastest press for producing printed envelopes of all sizes.

Halm Super Jet Press

The comprehensive reconditioning process applied by Curtius Technologies Inc. begins with dismantling 100% of the pre-owned Halm Super Jet press. The metallic frame is then pressure-washed and all obsolete electrical and mechanical parts –in particular those in contact with paper are replaced. The press is also completely rewired and upgraded with PLCs (programmable logic controllers) thus eliminating outdated relays.

The reconstructed machine is then fitted with a new upgraded belt transmission system, a dual solenoid system, source of expensive maintenance, is replaced by compressed air piston, and a systematic installation of onboard drive guarantees a smooth, quiet, energy efficient and low maintenance operation even at high speed. The feeder chains are also upgraded with timing belts to minimize risk of jams.

Last but not least, a new alphanumerical screen upgrade allows operators to set the type and the number of envelopes per batch; once the machine has reached the requested amount of envelopes it will stop automatically. Switching settings from 1up to 2up or 4up can be done easily by simply entering the desired setting on the screen. The easy-to-use screen can also show the location of any occurring jam thus diminishing machine downtime.

The result of such a thorough reconditioning process? A fully reconstructed and upgraded Halm Super Jet Press that will exceed original specifications at a fraction of the cost of new equipment. With this perfector press like new you can do two-color quality work on large documents, up to 12” x 18″ in size. Full bleed is possible on the front of the document, regardless of size, and when perfecting up to 9″ x 12″. The standard dual feeders enable you to run a larger variety of envelope sizes. You can also run clasp and latex envelopes as well as ballot and proxy cards. With the ability to run 4-up, you can print at speeds of up to 70,000 impressions per hour. See for yourselves.

Curtius Technologies Inc. was one of the few companies specialized in trading pre-owned envelope-converting and envelope-printing machines represented at Drupa 2012 but was definitely the only company in the envelope industry actually rebuilding and upgrading such machines with the latest technology.

The Curtius Rebuilding program, which was the key feature of our booth, received extremely positive feedback from the 150+ international companies that paid us a visit. This thorough program, honed by 20 years of technical expertise in the envelope industry is a two-step process, which includes stripping down the outdated envelope-making machine to replace all electrical as well as all wear and tear parts and then adding state-of-the-art servo-technology upgrades to transform the reassembled machine into a fully automated envelope-making equipment that exceeds original performances at a fraction of the cost of new equipment. What’s more, all servo-technology upgrades from Curtius Technologies can be tailored-programed to match exact production requirements.

It’s always nice to meet with customers

“All of our expectations were fulfilled” says Ludovic de Potesta, President of Curtius Technologies, satisfied with the Drupa 2012. “We were able to present ourselves as the only company on the market today offering custom advanced electronic upgrades on reconditioned envelope-making equipment, it’s a great opportunity for us” he adds. “It’s even more true now that leading manufacturers such as Winkler + Dünnebier are clearly focusing on inserting machines and digital printing rather than envelope equipment” concludes de Potesta.

Overall, the Print media business demonstrated once more at Drupa 2012, the world’s largest B2B trade fair in its sector with 314,500 visitors, that print has potential and that the industry is investing heavily in its future.

So a big “thank you” to all our customers, prospects and partners that helped us achieve our best show ever and see you in Düsseldorf in June 2016!

Are you planning on starting or expanding your envelope business but want to keep the cost-of-ownership of your envelope equipment down?  If so, take a look at re-manufactured and upgraded pre-owned envelope-making machines. They can meet or exceed original design and performance specifications of new equipment at a fraction of the cost, thus sharpening your company’s competitive edge.

So what exactly is a fully reconstructed and upgraded envelope-making machine? For the sake of the argument, I have chosen to describe a W+D 102, a reel-fed envelope machine fully reconstructed and upgraded by Curtius Technologies.

The first step of the re-manufacturing process includes stripping down the original W+D 102 envelope-making machine to replace all wear and tear parts (rubber rolls, belts, chains, busing, bearing…), rewire it and install a new electrical box. A new upgraded belt transmission system is also installed throughout the machine and in particular in the Printing unit, as shown below. This boosts the overall performance of the equipment and lowers maintenance costs thanks to more readily available spare parts.

The machine is then fitted with new technology, enhancements and upgrades designed and engineered by Curtius Technologies and its partners. On the W+D 102 such upgrades include for example the installation of a high-speed window patcher –that will immediately increase the maximum speed as well as upgrades such as doctor blade system, which guarantees a sharper printing quality even at high speed.
