Manufacturing apparatus for producing a curved contour on at least one end face of a roll and method for producing a curved contour on the at least one end face with the manufacturing apparatus

A manufacturing apparatus for producing a curved contour on an end face of a roll, wherein the roll has a lateral surface extending radially around an axis of rotation of the roll, the manufacturing apparatus comprising:

• a grinding device for grinding the curved contour on the end face;
• and
• a holding device, linearly movable relative to the grinding device, for holding the roll between the holding device and the grinding device;
• wherein the grinding device includes a grinding channel and a channel wall, the grinding channel including an upper grinding profile configured to produce a first curved contour on the end face of the roll and a lower grinding profile configured to produce a second curved contour on a further end face of the roll;
• wherein the channel wall extends from the upper grinding profile to the lower grinding profile;
• wherein the grinding device is designed such that the axis of rotation of the roll extends parallel to the channel wall;
• wherein the roll can be driven by a linear motion of the holding device relative to the grinding device to roll on the grinding device and to pass through the grinding channel in a pass direction;
• and
• wherein the pass direction is orthogonal to the axis of rotation.
