Abstract

1,270,314. Abrading; rolling. REYNOLDS METALS CO. 26 Aug., 1969 [29 Aug., 1968; 1 April, 1969; 8 May, 1969], No. 42495/69. Headings B3D and B3M. Accumulated material is removed from a roll, Figs. 4 and 5, in a rolling mill by flailing the roll surface with flexible elements S which rub abrasive particles over the roll surface. Abrasive material may be fed independently, or the elements may be of abrasive-coated paper, cloth, plastics &c. The elements S are grouped on shafts T to form cylinders F, slides 2 bearing the shafts T being adjustable to position the cylinders F by means of piston/cylinder units 5, with an adjustable stop 11 limiting advance. Drive is transmitted to each cylinder from a motor 18 via sprockets 12, 14, 15, 25 and chains 17, 26, 28, pivotable brackets 21, supporting the sprockets 25, being lockable by bolt 23 according to the working positions of the cylinders F. In a modified construction, Fig. 6, an hydraulic piston/cylinder unit 111 may shift the flailing cylinder between operative and inoperative positions by means of a supporting parallelogram linkage 104-110, a further piston/cylinder unit 117 allowing close positioning of the flailing cylinder within the limits of a nut 126. Drive from a motor 127 is transmitted by a chain 131, an hydraulically movable roller 132 providing chain tension. A housing 135 is provided to collect dislodged material, a nozzle 141 introducing a flushing jet, e.g. of water, while material is discharged through an outlet 140. In a further form, Figs. 7 and 8 (not shown), the housing 135 is provided with two edge seals, c.f. 136, for direct engagement with the roll 102. To ensure an even effect, the flailing cylinder may be reciprocated axially by a piston/cylinder unit 33, Fig. 4, acting on a disc 30 which meshes with a further disc 29 on the flailing cylinder shaft.
