Roller Cutting Machines / Unwinder
It is important for the roller cutting machine to prevent the entry of air or rather to allow for a controlled entry of air into the paper roll while winding up the paper web.
In each installation to be used - be it Vari Top, Vari Plus or Vari Step - the use of rollers with rubber coverings (such as pressure rollers, draught diverter rollers or rider rollers) is required. Their function is to squeeze the air out of the wound-up paper web or to evenly distribute the air within it. The desired aim is to produce a roll of paper web wound without dents, with straight edges and with uniform application of winding force throughout.
Since then, the standard has come to include different profiling designs - our joint development with the company Jagenberg - as well as special new geometries tailored customer-specific problems that we have been made aware of.
It is important in a winder that the paper is wound without air or a controlled amount of air in the paper roll.
Whether you have a Vari Top, Vari Plus or Vari Step, rubber-coated rollers such as pressure rollers, draft breaker rollers or rider rollers, the rollers have the function of squeezing the air or distributing it homogeneously in the roll. The goal is a callus-free, well-known, even, hard-wound paper roll.
Different profiling designs, which we developed together with Jagenberg, have been standard ever since.
But also new geometry that have been created specifically for special customer problems.
The profile design on pressure rolls was developed in cooperation with Jagenberg and has meanwhile become an industry standard.
The production of draught damper rolls is part of our product portfolio.
We offer a complete range of services from renewing rubber coverings for rolls, including balancing, through to the renovation of an entire system.
