<p>1,220,432. Metal wire guides. MORGARDSHAMMAR A.B. 9 April, 1969 [9 April, 1968], No. 18092/69. Heading B3W. The front and rear crop of hot-wire passing from a rolling mill to a reel 8 are severed by shears 4 and guided by switch guide 3 to toggle shears 6 for cutting up into lengths e.g. for samples. To retard the cut lengths moving from the mill at high speed 16 prevent their being damaged and to maintain their order of cutting a guide pipe 9 leads from the shears 6 substantially tangentially at 12 into a cylindrical or conical drum 10. The cut lengths are constrained by centrifugal force to follow a path around the inner surface of the drum, finally falling through an opening 13 on to a conveyer 14. In use, when a predetermined crop length has passed through the switch guide 3 in the full line position an impulse switches the guide to the broken line position and the shears 4 makes a clean cut through the wire. For identification of the cut lengths a spring 11 coats the crop portions nearest the clean cut with a metal oxide slurry. Two spray guns with different coloured sprays may be used for the front and rear crop respectively.</p> |
