Abstract

PURPOSE: To prevent the occurrence of burr and blurr by vertically adjusting a chock supporting an upper round tooth shaft above a lower straight tooth by a taper member to control the depth of cut for material to be cut, so that nipping and reverse shearing are caused by rolls in the next process.
CONSTITUTION: A push-pull bolt 10 is rotated to slide a taper member 9, whereby the vertical motion of a chock 6 is adjusted to change the distance between an upper round tooth 7 and a straight tooth 4. An electric motor 11 is driven to rotate a screw shaft 13 through a speed reducer 12, so that a frame 17 is shifted by the screw-engagement with a female screw 14 to move the upper round blade 7 in the direction of an arrow A. Accordingly, a plate 20 placed and transported on a receive roller is cut about 65W90% of board thickness by the lower straight blade 4 and the upper round blade 7 to be cut to half, and then pressed and reverse-sheared by rolls.
