Abstract

1,239,465. Shearing. HAMMERLE A. G. 25 Sept., 1968 [4 Oct., 1967], No. 45436/68. Heading B3W. A sheet metal shear comprises two blades (2), (3) ,(Figs. 2 and 3, not shown), fixedly mounted perpendicular to each other in a feed table and two co-operating upper blades, one blade (7), (Fig. 2), being mounted in a holder 4 pivotable on shafts 5, 6 and the other blade 9 being pivotable about the same axis as the blade 7, preferably an extension 8 of the shaft 6, for movement in a vertical plane perpendicular to the cutting plane of the blade 7 and being guided by adjustable members 10, 10<SP>1</SP>, 10<SP>11</SP>, 11, 11<SP>1</SP>. To cut a sheet to rectangular shape both pairs of blades are actuated simultaneously, the sheet is turned through 180 degrees and the cutting operation repeated. Alternatively the pairs of blades can be actuated separately, one pair acting as edge trimmers and the pair at right angles thereto as scrap shears.
