ROLLER HEAD UNIT
Overview
The roller head unit consists of a single or duplex extruder, a die head, and a vertical two-ball calender with head clamping devices. The broad width head and calender form the rubber compound into a sheet of uniform thickness, which can be varied from 0.5 mm -20 mm or greater in thickness. Nakata roller head units provide significant benefits over conventional calender systems in the production of inner liners, rubber sheets, V-belts, and elastic components.
