Abstract
1297182 Shearing SCHLOEMANN AG 30 April 1970 [7 May 1969] 20934/70 Heading B3W In reciprocating shears for cutting profiled sections such as T or I girders the blades are shaped to accommodate the sections and at least one of the blades is so formed that in the region(s) where the section is of greater depth in the shearing direction, i.e. at the flanges P2 Fig. 3, than in an adjacent region or regions, i.e. at the web P, the cutting edge and the blade face facing the shearing plane are further from the shearing plane than they are in said adjacent region(s). The blades may be grooved at 5b, 6b, Fig. 3, ground at "a" Fig. 10, or tilted, Fig. 13 (not shown), to achieve this spacing.
