Performance:
The bow amount is continuously adjustable by turning the square shaft by means of a key or by operating the hand pump. A locking device inside the axle limits the predetermined max. bow.

After having adjusted the bow, any drive belt fitted must be checked for an increase or decrease in belt tension. In rolls with PTFE covers the bow amount should never exceed more than 1,2 % of the web length.
