FACTS FROM OUR HISTORY

The story began in the middle of 1977 when during commissioning of just installed 4 roll calender a hacksaw blade was incidentally passed through gap (minimal) between the 3rd and 4th roll resulting in considerable dents left on the rolls.

In the searching for a repair method to eliminate this defect various techniques were tried, from a grinder installed between the calender frames to grinding unit with friction drive.

But it was all in vain. Eventually, a suitable method of grinding was found which allowed us to receive a film that met the required parameters.

Later on this method was greatly improved, and now we ensure the required tolerance range of calibrating gap between calendar rolls of mere microns.

We have ground hundreds of rolls at various production facilities that use calender, doubling and finishing, and rolling equipment, etc.

Moreover, grinding was performed both on cylindrical and cambered rolls and, in some cases, regrinding of cylindrical rolls into cambered ones was done with cambering size indicated by the customer.

Also, we have vast experience in the field of engraving reconditioning and grinding of cylindrical engraved and cambered rolls used for manufacturing of thermobonded nonwoven fabric.
