Abstract
1367806 Stretch-straightening apparatus I UNGERER 26 Jan 1972 [13 May 1971] 3634/72 Heading B3E A stretch-straightening apparatus comprising a roll straightening machine 4, a backstay stand 2 and a traction stand 3 has a comparator 10 to compare the speeds of either the end rolls 8, 9 of the straightening machine or adjacent strip speed measuring rolls (11), (12), Fig. 2 (not shown), and the output of the comparator is used to adjust the roll speeds of the traction and/or back-up stand to change the strip stretch. The rolls of the straightening machine may be idle or driven. The output of the comparator 10 may be corrected by the outputs of a pair of further comparators which compare the speeds of the last roll of the backstay stand with the first roll of the straightening machine and the first roll of the traction stand with the last roll of the straightening machine. By using the comparators the desired stretch for the strip can be achieved by correction of the roll speeds.
