Roller coverings - Import export

Hannecard provides covered rollers for stripping used to separate the packaging from the skeleton after die-cutting. These rollers are the counterpart of a metal roll with pins and air exhaust. The pins ensure the separation between the two cut parts of the cardboard yet wear out the rubber roller during operations, requiring regular recovering of the roller. Using Hannethane rollers allows you to reduce the recovering frequency by a ratio of 4 to 6.

Hannecard provides over a thousand custom-made roller covering solutions, from rubber and polyurethane to composite and spray coating. To improve the lifespan and performance of the roller coverings, we are constantly developing new compound formulations.

In the domain of adhesive film and paper production, several techniques can be applied for primer and finish coating. Hannecard supplies rubber, as well as polyurethane roller coverings suited for both water and solvent-based coatings. Depending on the process, the pick-up, transfer or back-up roll can be elastomer coated. All qualities mentioned below are also available in antistatic versions.

Managing documents can take a lot of time. Therefor Hannecard recently invested in the countroll® platform, an online management system especially developed for rollers, that brings all your documents and roller info digitally together! Hannecard is the first roller covering company ever who makes it possible for its customers to digitally consult and manage all their roller documents like label data, inspection reports, technical data sheets, technical drawing, and so on. All rollers covered by Hannecard are automatically equipped with a small countroll® tag and a QR-code sticker. By scanning this tag or QR code all roller data and documents can be easily consulted and managed by the customer through the cloud based countroll® web portal and the free countroll® app.

To assure non-stick, non-crushing and non-marking for fine media (low density paper, thin film and flexible packaging) and ‘correcting’ characteristics for the contacting web, Hannecard has developed MicroGraf, a micro-cellular foam rubber for the covering of the paster rollers for the splices. MicroGraf is soft and assures the desired constant elasticity. This quality allows for planar corrections and the elimination of air pockets in the spliced web reels. As a variant, we can extend the MicroGraf paster roller covering in a double layered version called MicroGraf+. In this case, the top layer is a compact harder rubber, which can be finished helicoidally or with other special types of grooves, according to the web medium. For rougher media like Kraft paper you can rely on our low-hardness polyurethane series Splice-O-Graf, that comes in hardnesses of 22 or 30 Shore A, and which combines a high elasticity with increased mechanical and dynamical properties.

The disadvantage of traditional textile covered rollers is that they do not assure uniform inking jobs at high printing speeds. Hannecard has developed a solid alternative: DoseRight, a laser-engraved 60 Shore A rubber roll covering. Different laser engraved patterns (squared, pyramidal, honeycomb, scattered, etc.) are available, in function of inking type and application. Laser engraved inking rollers assure a uniform and correct inking of the printing roll, avoid ghost image appearance and reduce the ink spillage. The advantages of DoseRight include: Inking rollers No cell filling No lines No ghost image

Precise roller grinding is an essential step in ensuring a perfect roller surface, which in turn is crucial to efficient operations and optimum quality of finished products. With this in mind, Hannecard provides regrinding and profiling of covered rollers for its customers. Along with grinding, drilling and grooving can also be provided. To guarantee optimum performance of the grinding profile, Hannecard carries out nip measurements (static and dynamic) and conducts a wear-profile analysis.
