Abstract

249,516. Bliss Co., E. W., (Assignees of Beyer, 0. S.). March 21, 1925, [Convention date]. Shearing; punches.-A sheet A is cut into scalloped strips B extending longitudinally of the sheet in a machine with opposed shearing dies 12, 13 having cutting edges 17 adapted each to cut one side of a scallop and arranged to cut simultaneously the reversed sides of the scallops of one lateral series. Alternately acting crank-operated press mechanism and feeding means are provided, the latter feeding the shafts by pawl-actuated rollers after each cutting stroke. The die 12 is inclined to the die 13 and cutting progresses from end to end of the blades. The cutting edges of the die are larger than the feed steps to ensure the cuts overlapping to form continuous cuts. Spring-urged strippers 60, 61 are attached to the dies.
