Tight grip on cylinder

Polywest at Labelexpo Europe with new Label-Sleeve-Line

Labelllinie Polywest is to present its newest product line exclusively at this year´s Labelexpo Europe in Brussels to the public. Label and narrow web applications in particular require high-precision and reliable working equipment which offers high run-out accuracy and dimensional stability. Especially where very small sleeves are used, the limited contact surface of cylinder and sleeve has to be used for an optimal grip to protect them against torsion and slipping.

The Polywest-Label-Line (available with two different surfaces) has been designed specifically to fulfil these requirements. It is characterized by a new manufacturing technology and the use of special materials that give the particular tight grip on the cylinder as well as high dimensional stability. These materials keep printing characteristics even when subjected to varying degrees of temperature and humidity or extreme use. Smallest tolerances in diameter and true run allow the required precision work. Sleeves of the Label-Line are due to their construction extremely light and easy to handle. Further information about the new product line will be published exclusively at the trade show.

“Drupa has been a great success for us“, Heinz W. Lorig, Managing Partner of Polywest, points out. „We could show that we–as a medium-sized company–can keep up with the high level the big groups represent“, Heinz W. Lorig adds. While other competitors were joining big groups in the past, Polywest is still retaining its independence.

One system – Individual solutions

As one of the most successful international manufacturers of plate mounting sleeves and adapter technology for flexography, Polywest’s focus is now on system solutions. Many years of experience and the continuous developments in the flexo printing industry have shown that there is always more than one way to reach a goal. Today system solutions are requested with flexible components which are easy to handle and in addition reduce costs and set-up times. Polywest offers a system consisting of adapters for bridging big printing circumferences and sleeves for plate mounting as well as direct-engraving sleeves. The product range is a complementary range characterized by its enormous flexibility. It is compatible with nearly every sleeve system available.

Drupa 2008

Polywest: Internationally well positioned.

The wide range was particularly appreciated by international drupa visitors from Asia, Latin America and the North American countries. They were especially interested in adapter technology and direct-engraving sleeves. The direct-engraving sleeves are manufactured with high-quality materials and convince through their excellent printing characteristics and their rapid operational readiness after the laser engraving process. The print layout is engraved directly into the sleeve surface with laser. Time consuming exposure, washing and drying processes which are needed when printing with photopolymer forms are eliminated.

Drupa 2008

Polywest rouses international interests.

At this year’s drupa many new and interesting business contacts could be established. Compared to drupa 2004 the number of visitors has lightly decreased, but most of the visitors were better informed, so that the conversations were on a high level and very effective. The final work is currently made at Polywest and the closing results are getting summarized.

Drupa 2008

What’s new at Polywest

Polywest has done a big step forward in the further development of adapter technology with its new product Spacer. The Spacer offers, especially in the field of thin sleeve technology, enormous advantages compared to the conventional adapter technology. With the innovative Spacer technology printers will be able to reduce costs, save time and above all allow a simple but save mounting of the thin sleeves. The new Spacer of Polywest meets exactly these criteria. The thin sleeve is mounted on the adapter outside of the printing machine on a separate Spacer-Mounter. This offers an easier handling and leads to a precise fitting of the sleeves compared to the mounting inside of a press. Also set-up times are reduced.

Afterwards the Spacer with the mounted thin sleeve can be used as any other plate mounting sleeve regardless of the position of the air outlets on the air mandrel or the adapter.

Polywest Sleeve Systems enlarges its product range with a brand new adapter technology

Polywest Sleeve Systems is one of the most successful suppliers and manufacturers of adapter technology and sleeves for flexo printing worldwide. For more than 20 years Polywest is a development leader in the printing industry – especially the flexo printing industry. Heinz W. Lorig, Managing Partner of Polywest, and his staff pursue two goals: first, to always look forward into the future and second, to anticipate the problems and needs of the printers and to develop and offer according solutions. The adapter technology has made significant developments due to the innovative ideas of Polywest. “We invested a lot, especially in the development and the construction of adapters” comments Heinz W. Lorig „of course the sleeve production has a significant importance in our daily business as well. Also here the increasing demand documents our success.”

Many years of experience and the continuous developments in the flexo printing industry have shown that there is always more than one way to reach a goal. “The demand on system solutions and therefore flexible components is getting bigger and bigger. We are aware of this trend and we grow with the needs of the printers“, Heinz W. Lorig points out. The Polywest Sleeve System offers a wide range of plate mounting sleeves, adapters and direct engraving sleeves as well as various equipment. The large assortment is a complementary range characterized by its enormous flexibility. This means that the Polywest portfolio is compatible with nearly every sleeve system available.

The classics of Polywest as there are the Hybrid Sleeve Adapter (HSA), the Standard Adapter and the Soft Adapter offer for every format bridging and sleeve type the adequate adapter. The latest developments of plate mounting sleeves – Onyx and Rubin – have shown it already in practice. They convince by their simple fitting behaviour and excellent printing results. Sleeves of the product families Onyx and Rubin show optimal cutting and solvent resistance and a very good adhesion of different tape types. Sleeves of the Onyx product line are conductive according to the EU directive ATEX 95 and are especially designed for the use together with solvent inks. With the direct engraving sleeves Novotec – ideal for UV- and waterbased inks – and Evotec – suitable for solvent inks – endless seamless illustrations can be lasered directly on the sleeve. This saves valuable time and costs in the working process. Both of the printing surfaces are offered as plate as well.

The latest development of Polywest is the Spacer. With this product the German company shows again its excellent skills in further developing of the existing adapter technologies. The problems which had to be solved were the difficulties that are often shown while mounting extreme thin sleeves on conventional adapters. The fitting and the handling of these thin sleeves had to be simplified. Here innovations were needed which do not only decrease costs and shorten fitting processes but afford a simple and safe mounting of these extreme thin and fragile sleeves.

Spacer

The Polywest Spacer can be used with an already mounted thin sleeve as any other mounting sleeve.

The Spacer of Polywest meets exactly these criteria. Heinz W. Lorig explains: „Every now and then it happens that thin sleeves are buckled or damaged while changing inside of the press. This problem is eliminated by using the Spacer.”

The Spacer is not a normal adapter. It is used and handled with the already mounted thin sleeve like a common sleeve in the press. Spacer and thin sleeve are mounted outside the press to a unit with the use of the Spacer-Fitter. The Spacer itself has an elaborated air guiding system with frontal air inlets and radial air outlets. The conditions for mounting a thin sleeve are improved considerably by the construction of the air ducts and the mechanic of the Spacer-Fitter. The Spacer-Fitter is offered in a vertical and a horizontal version according to the printer’s wishes and needs. The Spacer is available from a wall thickness of at least 14 mm and should not exceed a wall thickness of more than 72 mm. According to the demands on thin sleeve carriers the Spacer has a soft surface. Like all adapters from Polywest the Spacer is conductive according to the ATEX 95 directive.

Illustration of the Spacer in cross-section

Eventually the Spacer with the mounted thin sleeve can be used as any other plate mounting sleeve regardless of the position of the air outlets on the air mandrel or the Adapter.

RUBIN

«Rubin» – that is the name of a new product of sleeve manufacturer polywest, based in Ahaus, Germany. Short delivery times, high quality and good after-sales service are the main requirements of customers.

Sleeve Adapter

Adaptors and sleeves are both innovative technologies offering the user a whole range of benefits. However, this requires precise adaptation as well as faultless running of both technologies. In recent years, the combined use of adaptors and sleeves on flexo printing presses has often caused detractions or even interruptions of the production run.
