● Diameter of main top , bottom drive wheel is Φ910mm for DR30A, while those which in DR25A is Φ846mm for top and Φ640mm for bottom.

● Bevel gear drive structure is adapted for the driving gearbox. After heat treatment for high-quality alloy gear, the toth surface is grinded;it is high-class gear with low noise and large transmiting torque.

● Bearing position is lubricated by pump oil; and auto-splashing lubrication is adapted for gears in the gear box.

● Inverter motor is adapted for main drive; The speed regulation range is wide as well asstable running.

● Independent driving box is adaptedfor direct drive by two shafts; and the large driving wheel guarantees the stability and relability during high-speed operation.

● Synchronous signal motor that can synchronize with glue machine is set onthe main shafts of driving gearbox, so as facilitate the adjustment of synchronization function.

● Rolls are wrapped by the V-Shaped abrasion resistant rubber.
