Abstract

PURPOSE: Rotary cutter is rotated and makes both forward and backward movement in the right angle to the feed direction of print sheet. By doing so, through connector terminal of the print sheet it edge can be chamfered without producing burr.
CONSTITUTION: When a table 5 reaches to the front side of a cutter body 21, a print sheet 1 attached on the table is cut in its under surface angle installed with connector terminal of the print sheet 1 by means of one-side direction of a cutter 32. At the same time, by the reciprocating movement of the cutter 32 the burr formed in each terminal 2 is cut at cutting time. Through the feed of the table 5, chamfering is effected over all edge of the print sheet 1 and in the end of feed process the feed direction of a cylinder 6 is rotated reversely to return the table to the inicial position. Then, the other side is also cut in the same operation for terminating the chamfering.
