40 Extrusion International 3/2020 EXTRUSION TECHNOLOGIES For UNION it is clear that the market is going to demand for quick actions, to satisfy the need of many companies to change their production, which probably will not be the same anymore.

The latest news of this technology is represented by a new profile of the screw, new gear pump (made by UNION) and screen changer, that stabilize the process as never before, re- ducing drastically the pulsations in the die which is a crucial condition, to obtain superior optical quality. Another great peculiarity of the UNION PC solid sheet tech- nology is the horizontal calender with a pivoting exit roll that gurantee a precise and fast positioning during thickness change, all synchronised in automatic mode. The postioning of the rolls is secured by an innovative hy- draulic systemworking always in “active mode” and able to guaranteed a tollerance of 0,02 mm only. All the calender rolls are individually driven and equipped of the last genera- tion gears, type “backlash free”, with direct coupling to the rolls. The downstream is equipped with a double longitudinal blade/sawcutting station for the correct cutting of the differ- ent thicknesses and with an anti-scratch polyethylene coat- ing systemon both sides of the sheet. The line ends with a rotating saw cross cutter with an auto- matic stacking device “take&place” type, for sheets up to 6 mt long. The hourly output can be up to 1000 kg/hr, thick- nesses from 1 to 20 mm and useful width 2050 mm. UNION has optimized their production to secure a fast de- livery. UNION Officine Meccaniche S.p.A.
