Film and Sheet Calenders
Laboratory calenders are used in the development of continuous processes.
They are suitable for the production of film and sheet of different layer thicknesses made from a wide range of polymer materials such as PVC, polyolefins, PU and many others.
Calenders in L, F, I or Z configuration with roll diameters of 168 mm, 250 mm and 350 mm are available.

Calenders for laminated PVC
RODOLFO COMERIO designs and manufactures calendering lines for calendered PVC lamination to various supporting materials, where the calender is the main machine in the line. The rolls, 2 or 3, inclined "I" configuration, represent the heart of the machine ; for this reason, based upon the output to be achieved, a design team offers the max possible support to the Customer for the selection of diameter, width, material, technical features of the rolls. RODOLFO COMERIO calenders, furthermore, can be enriched by the most advanced automatic control and adjustment systems for thickness and profile of the film, by means of rolls shifting, roll-bending, cross-axis and preloading. These mechanisms, furthermore, can be integrated with electronics, in order to guarantee calendering process control by gathering and automatically adjusting all production parameters.
The special arrangement of the rolls permits then to apply a wide range of accessory devices such as, for example, the laminating group in calender and embossing group provided with a device to quickly change the engraved and rubber roll.
