Abstract

1423996 Rolling mills DAVY-LOEWY Ltd 19 April 1973 [19 May 1972] 23666/72 Heading B3M [Also in Division B8] Entry equipment for a rolling mill stand comprises two coil supporting devices for paying out strip to the stand, each device having a separate feed mechanism for directing the leading end of a strip to the stand. As shown, strip from a coil 21B is being fed to the rolls 10 of the stand through pinch rolls 14B and a roller leveller 15B. The leading end of a strip from coil 21A has been fed through pinch rolls 30 and 14A and roller levellers 31 and 15A to a point 34A, ready for subsequent insertion between the mill rolls 10. When the end of coil 21B has passed through the stand, the assembly of levellers and pinch rolls 14 and 15 is lowered in a framework 18 until the point 34A is aligned with the mill pass line 12. The leading end of coil 21A can then rapidly be fed through the mill. The leading end of a further coil located on spool 20B will then be prepared in a similar manner by feeding it to rolls 14B and leveller 15B. Peeler aprons 34 and 25 assist in peeling and guiding strip from the coils. In an alternative arrangement (Fig. 2, not shown), the coils are disposed one above and one below the pass line, and a common, pivotable pinch roll is used in the feeding of strip from both coils.
