Patent no. RO122981/2010
The present invention refers to a laboratory equipment for
simulation of the calendering of polymeric materials.
The technical problem solved by the present invention is
related to the sheet thickness reduction. In order to achieve
the final sheet thickness, the gap between the rolls is
adjusted by means of two calendar rolls which are moving
Description in a radial direction within the range of 0÷5 mm. The
radial movement of the rolls is controlled by a
micrometric feed system.
The advantages of the proposed three-rolls calender are:
- It is the first laboratory equipment which allows the
simulation of the calendering of polymeric materials;
- It has a simple and robust design, and allows the
adjustment of the distance between the calender rolls.
