Abstract

1,238,377. Circular saws. BROWN, BOVERI & CIE A.G. 23 Aug., 1968 [24 Aug., 1967], No. 40510/68. Heading B5L. [Also in Division B3] A plate or sheet 1 is divided into transverse strips by moving one or more tools e.g. circular saws 12 transversely to the feed direction of the sheet 1 to form a groove having a depth at least half the thickness of the sheet, and then rupturing the remaining metal by pivoting the partly divided strip. The dividing machine comprises a table 3, a transverse beam 5 on which a horizontal slide 8 is moved by rack and pinion drive to cut the groove, a tool slide 11 movable vertically by a worm-wheel 29, 30 and lead screw and nut 27, 28 drive to adjust the height of a saw or saws 12, and a transverse beam 13 which is pivoted about an axis immediately below the groove to rupture and separate a strip from the sheet 1. Hard ceramic inserts 18, 19 are placed at the adjacent edges of the table 3 and pivoting beam 13, and magnetic grips 20 (electro or permanent) hold the sheet 1 to the table 3. The sheet 1 may also be held to the table 3 by a suction device. Rollers 21 movable with the saw 12 also hold the sheet 1 against the table 3. The sheet 1 is traversed across the table 3 on the tops of submerged freely rotatable balls 22.
