Through a 2007 technological collaboration between ROLLTECH and POLYWEST (Germany), with its top share in Japan, we established POLYWEST JAPAN in beginning the production and sale of plastic sleeves domestically in International. As such, we are able to reduce delivery times and provide rapid response aftercare. New Material Sleeve “RUBIN” Compared to conventional sleeves, RUBIN has a more durable surface, which reduces bouncing during printing and improves print quality. RUBIN is difficult to cut and has excellent solvent resistance. Characteristics: -Sleeve wall thickness can be freely set between 1 and 72 mm (equivalent to a maximum printing repeat length of 440 mm) -Mounting and removal of the sleeve is conducted by simply blowing pressurized air with a load of 5 to 6 Kg/cm2 from the edge face of the air cylinder, so is extremely easy and improves work speed. When the air pressure is removed, the sleeve locks in place so that there is no misalignment, rotation, or slip during printing. -The sleeve can be attached to the cylinder with cushion tape and double-sided tape to greatly improve the printing efficiency of used sleeves. -Rubber mounting can be conducted as easily as with steel rolls, so can be used with various rolls, including flexo printing solid sleeves and gravure printing/coating impression rolls. -The inner diameter of the sleeve and the air cylinder have a straight structure.
