MINI 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.
MINI ROLLER HEAD UNIT
This unit can be used for the high speed profiling of small, thin gauge tire components, which can be used for direct application by strip winding to tire assembly units. This unit also can be used to produce small, thin gauge sheet for non-tire applications.
