Squeezing roller having an internal drive for a cold rolling system

A device for removing cooling lubricant during rolling of a rolled strip in a cold rolling mill with at least one roll stand, comprising

• a squeezing roller configured to be arranged between a first and a second roll housing of the roll stand, the squeezing roller having a roller shell and an internal electric rotary drive;
• a mount, in which the squeezing roller is mounted rotatably about an axis of rotation;
• a positioning device for positioning the squeezing roller against the rolled strip;
• and
• a control means for activating the rotary drive and the positioning device;
• wherein the rotary drive is fixedly connected to the roller shell, has a stator and a rotor and is embodied as an internal rotor;
• wherein a current speed of the rolled strip downstream of the roll stand is known to the control means, and the control means is configured to activate the rotary drive synchronously to the current speed of the rolled strip downstream of the roll stand;
• wherein the positioning device is configured to move the mount with the squeezing roller between a starting position and an end position;
• wherein, during rolling of the rolled strip in the roll stand, the roller shell:
• does not touch the rolled strip in the starting position, such that the rolled strip passes through the roll stand in a first strip running line, and
• makes contact to the rolled strip on an upper side in the end position and deflects the rolled strip downward into a second strip running line.
