Abstract (en)

[origin: WO2006084072A1] A linked transport mechanism and method that uses a single source of motive force to synchronously position multiple displaceable sensors of a shape-measuring assembly onto a roll received in a roll grinding machine. At least two sensors (28, 29) are mounted on linear slides on at least one measuring arm (1). The complete shape-measuring assembly includes at least three sensors (27, 28, 29) or measuring points to allow the calculation of the cross-sectional shape of the roll and the extraneous error movement of the roll. At least one measuring arm is connected to a linear guide (4) of the frame (3). The linear motor is connected between the frame and the measuring arms. The linked transport mechanism assures the synchronous accurate positioning of the sensors, each at a fixed angle through the roll center, over the entire range of roll diameters that the grinding machine may receive.
