On low speed machines the screens are driven by the suction couch rollers.
When the speed increases, it is necessary to use the drive roller to increase the drive capacity of the couch roller and to facilitate the transfer of the flat table sheet to the press sector., because due to the high speeds the amount of breaks that occur in this transfer increases a lot.
With the use of drive rollers it is possible to use a pickup suction roller to make the transfer, which almost completely eliminates paper breaks.
Our drive rollers are designed according to your use, considering its size, velocity, tractive force, material used, etc. They are manufactured according to the designed tolerance limits, and balanced for working speed.
