Abstract (en)
[origin: US7174758B2] A device for measuring the roll gap ( 7 ) between the working rollers ( 1 a: 1 b) of a cold or warm rolling stand for rolling out narrow or wide strips of metal, especially NE metal strips, by means of roll gap sensors ( 6 ) whose signals are transmitted to the servo-valves of the compressed oil control as a roll gap setpoint value for the piston cylinder units influencing said roll gap ( 7 ), and used to provide a roller gap measurement which is also suitable for such cases involving the lateral progression of said strip. In order to achieve said aim, the position or travel sensor ( 6 ) is provided in at least one bending cylinder ( 5 a ;5 b) for the working cylinder ( 1 a, 1 b) for indirect reference measurement of the roll gap via the positively or negatively acting bending cylinders ( 5 a; 5 b).
