Abstract

1,015,084. Metal strip feeds. I. PROPERZI. Sept. 25, 1963 [Oct. 6, 1962], No. 37782/63. Heading B3W. A device for forwarding a metal strip to a machine for performing an intermittent processing step comprises a curved former, a pair of curved arms pivotally mounted with respect to the former about an axis transverse to the direction of strip travel over the former with their free ends directed towards each other and defining with the former a space through which the strip may pass, and means for oscillating the arms to permit build-up of and subsequently express a loop of strip within the space, the means for oscillating the arms being adapted to be operatively connected to the machine for oscillation in synchronization with the processing step. Strip N from a continuous casting unit 1 passes through a tandem rolling mill 2 to the feed device A and then to a reciprocating press 4 which is driven from the last roll stand through a change-speed unit 13. The feed device A comprises a frame 23 in which reciprocates a slide 19 which is driven by a connecting-rod 24 mounted on an adjustable crank-pin 25, which is itself driven, by a shaft 5, from the press 4. Pivoted to the slide 19 are links 18 which are also pivoted to strip pressing arms 16 at the points 21. The arms 16 are also pivoted at the points 17 to supports 14, on which rests a curved former 15 over which the strip N passes. The movement of the slide 19 is synchronized with the press so that while the leading end of the strip is stationary in the press, the arms 16 are raised by the slide 19 and allow a loop of strip to form above the former 15 to accommodate the material which is forwarded continuously from the rolling mill. As the slide 19 subsequently descends the accumulated strip is fed forward to the press.
