Abstract

1431984 Rolling mills VEREINIGTE FLUGTECHNISCHE WERKE - FOKKER GmbH 18 May 1973 [20 May 1972] 23868/73 Heading B3M [Also in Divisions G1 and G3] A roll stand comprises a pair of working rolls 10, 11, a pair of guaging surfaces 14, 15 arranged to vary in spacing as the roll gap spacing varies, and means to contactlessly measure and to control the spacing of the surfaces 14, 15, the surface 15 being adjustable. In Fig. 1, gauge rings 12, 13 are provided at the ends of the rolls, surface 14 being provided by one of the gauge rings and surface 15 by the end surface of an adjustable pin 16. In Fig. 2, the surface 14 is provided by a fixed pin on gauge ring 12. In Fig. 3 (not shown) the surface 14 is provided by the end portion of the roll. In Fig. 4 (not shown) the surfaces 14, 15 are provided by pins mounted on the roll chocks, the surface 15 being provided by an adjustable pin. The spacing of surfaces 14, 15 may be measured by an inductive, capacitative or optical arrangement.
