摘要

1. Control apparatus for a strip mill using measurement of the tractive force in a loop of a strip between two consecutive roll stands of the strip mill, this apparatus being equipped with force measuring means (15) arranged between the free end of a strip tensioning device (1, 2) and the rolling contact bearing elements (10) of a roller (3) which is supported by the said tensioning device, characterised in that each bearing of the roller (3) comprises two parts, a part (4) situated externally of the roller and integral with the free end of the tensioning device (2), and a part (9, 10, 11, 12) situated internally of the roller, and in that the force measuring means (15) is fixed on the one hand in the part (4) situated externally of the roller (3) and on the other hand in the stationary part (9) of the rolling contact bearing element system (10) situated internally of the roller (3) and constitutes the sole mechanical connection element between the said external and internal parts of the bearing.
