Abstract
An apparatus for processing metallic strip material comprises a feeder for feeding strip material; a strip drive with at least one controllable traction drive with a carrier and a motor, a drivable traction loop and a press assembly, wherein the power of the motor and the pressing force of the press assembly are variably controllable; a roller assembly for flexible rolling; a measuring device for measuring a physical parameter of a component acting on the strip material; wherein the driving power of the motor is controllable on the basis of the physical parameter measured by the measuring device.

An apparatus for processing metal strip material, comprising:
- a feeder;
- a strip driver which has at least one controllable traction drive with at least one motor and a traction loop rotatably drivable by the motor, and a press assembly arranged to press the traction loop against the strip material, wherein a driving force is transmittable from the traction loop, under frictional contact with the strip material, to the strip material;
- a plurality of rollers arranged to produce a variable sheet thickness in the strip material over the length of the strip material by varying a roll gap;
- a measuring device arranged to measure a physical variable acting on the strip material;
- wherein the at least one traction drive is fixed in longitudinal direction of the strip material;
- and
- a control unit configured to control a drive torque of the motor based on the physical variable measured by the measuring device, wherein, by changing the drive torque of the motor, the driving force from the traction drive acting on the strip material is variably adjustable.
A method of processing metal strip material comprising:
- driving the strip material by a strip drive, wherein the strip material is uncoiled from a feeder and fed to downstream rollers for flexible rolling, wherein the strip drive includes at least one controllable traction loop which is rotatably drivable by a motor, and a press assembly arranged to press the traction loop against the strip material;
- sensing a physical value acting on the strip material by a measuring device arranged on the rollers for flexible rolling or its periphery;
- wherein the at least one traction loop is fixed stationarily in the longitudinal direction of the strip material to a stationary part, and
- wherein the drive torque of the motor is controlled as a function of the physical value measured by the measuring device, with the drive force acting on the strip material by the traction loop being varied by changing the drive torque of the motor.
