Abstract

491,639. Rolling bands. BANDEISEN. WALZWERKE AKT.-GES. Dec. 28, 1937, No. 35909. Convention date, March 5. [Class 83 (iv)] The speed of rollers 9, 10 pulling an endless band 1 through a cold mill 2 is automatically adjusted to give constant pull by means of a feeler roller 6 urged into a loop 5 of the band by a pressure piston 13 the rise or fall of the roller 6 operating electric contact 7 controlling the motors of the pulling rollers 9, 10. The pressure piston has a relatively large cross sectioned area and is operated by compressed air. A spring tension device 11 is also provided.
