Drive of transport rollers for all kinds of material webs.

When transporting material webs, in particular endless material webs, such as fabric or paper webs, this results often the task of removing the material webs tension or with an adjustable tension through a treatment to lead smasehine.

For this purpose, according to the innovation, it becomes elastic Drive the transport rollers between the transport rollers and their drive devices, for example electric motors, switched on a magnetic clutch, the drag force of which is adjustable.

In the existing clutch "special consisting of two mutually opposite in known manner halves" is formed so that the one coupling half has at its end face in a circle distributed permanent magnets ^ while on the other coupling half - are provided in the same manner distributed soft-iron armature.

To ensure that the transport rollers are carried along as sensitively as possible to. achieve." must be between the magnet and its intern a minimum distance of 0.4 to Qj, 6- mm is maintained, which by interposing, for example, Messiög strips Thickness happens 5. which is the immediate touch between magnets and armature prevents "

To change the driving force; the clutches _? so that in the web to be transported no "impermissible sewing tensions occur in the web a, ketones _? their halves are axially" displaceable with respect to one another and / or are arranged to be pivotable in an axial plane »
