Abrasive-band grinding device for rolls and a method for the control of an abrasive-band grinding device in the grinding of the faces of crowned rolls

摘要

The invention concerns an abrasive-band grinding device (10) for rolls, comprising an abrasive band (11), which is rotated by means of a motor (13). The abrasive band (11) is pressed against the face (T') of the roll (T) to be ground. The abrasive-band grinding device (10) for rolls comprises guide pulleys (12a1,12a2) for the abrasive band (11) and, between said guide pulleys, a contact pulley (15) which has been mounted to revolve. The contact pulley (15), by whose means the abrasive band (11) is pressed against the face to be ground, is controlled by means of an actuator (16), preferably a motor (16), so that the contact pulley (15) can be inclined in compliance with the roll face (T') to be ground.
