Abstract: A manufacturing apparatus for producing a curved contour on an end face of a roll includes a grinding device and a holding device, linearly movable relative to the grinding device. The grinding device is for grinding the curved contour on the end face. The holding device is for holding the roll between the holding device and the grinding device. A method for producing the curved contour on the end face using the manufacturing apparatus is also disclosed. The method includes driving the holding device to move in a linear fashion relative to the grinding device.

Abstract: A dressing device for profiling and sharpening a grinding tool includes a rotatable sharpening tool and a rotatable profiling tool axially offset from and settable relative to the rotatable sharpening tool. In one embodiment, the rotatable sharpening tool and the rotatable profiling tool have a common rotational axis, and the tools are settable along the common rotational axis. In another embodiment, a profiling tool axis of rotation is parallel to a sharpening tool axis of rotation. A method for dressing a grinding tool is also disclosed. The method includes profiling and sharpening the grinding tool with a single dressing device having a rotatable profiling tool with a first feed rate and a first advancement rate, and a rotatable sharpening tool with a second feed rate and a second advancement rate. The two feed rates or the two advancement rates are different.
