Torque Limiter Applications Printing Press

Torque Limiter
Typical Applications

4. Printing Press

Product:

Series 600 Torque Limiter

Application:

Printing Rolls – Magazine Printing Press

Function

As paper is drawn at high speed through the printing rolls, it can adhere to a roll and cause a major jam, damaging the mechanical drive components and shutting the whole press down for repair. An air-operated torque limiter is fitted to each roll stand (set of rolls). As soon as the paper jams, the torque limiter disengages and protects the drive
components. The torque limiter disengages and protects the drive components. The torque limiter also acts as a normal clutch, allowing individual roll stands to be connected and disconnected as required by the printing process.

Drive Specification

Electric motor driving through a flexible coupling and gears.

Torque Limiters:

Airjustor combined pneumatic torque limiter and clutch, directly coupled to the roll stand gearing.

Benefits

Damage to the drive components has been eliminated, thereby giving a major reduction in down time and repair costs. The disengaging clutch feature allows rolls to be disconnected automatically when not required. It also makes maintenance work easier and quicker, reducing costs. The production of the press has increased as a result.
