Abstract

The invention relates to a device for measuring the surface hardness of rolls (2) of paper or other material. Said device comprises at least one hardness measuring head (12) with at least one rotatably mounted contact roll to rest, under radial pressure, on the revolving roll (2) of paper or the like. The hardness measuring head (12) can be moved on a rail (11) substantially parallel to the winding axis of the roll (2) or the like and has means for evaluating the measuring signals of the hardness measuring head (12). It is proposed to provide first and second means to monitor and, optionally, influence parameters of a material strip wound to form the roll, such as roll hardness, strip tension, uniformity of roll diameter along the roll width and the like, during winding. Said means can be used to hold at least one of the contact rolls (126, 127; 126', 126'', 127'') in position on the roll (2) with a first force and to cause at least one of the contact rolls (126, 127; 127', 127'') to penetrate with a second force deeper into the surface than with the first force.
