Roll slitting machine is a machine suitable for length cutting of paper web, cardboard, laminate, foil, tape and similar materials.
The machine consists of a feed unit, on which a raw material reel is installed using a mechanical or air shaft. Through intermediate shafts,paper web enters a scoring unitconsisting of cylindrical and circular knives.
After cutting grooves are wound on bushings.
Slitting Machine Сevinini
A machine for continuous processing of polymer base into a homogeneous melt and shaping it by pushing through an extrusion die and a special calibrating device, the cross section of which corresponds to the configuration of the finished product.
The feedstock is poured (manually or with a special loader) into the extruder hopper. From the hopper, bypassing the neck of the charging funnel, the raw material enters the loading zone of the auger, and then is transported through the plasticization cylinder. From squeezing, mixing and contact with a heated cylinder and auger, the polymer raw material melts and turns into a homogeneous mass – the melt.
Calender is a machine for the continuous molding of a sheet of polymer or paper with transfering it through the gap between the rotating shafts. The result of calendering the web is obtained in the desired thickness and width.
