ABSTRACT:
Apparatus and a method of rejecting articles, such as can closures, are disclosed. The rejection of articles is obtained by variation in the length of a reciprocating member. In one mode of operation, a register of a multiregister counter is activated by an upstream sensor when a defective article is detected, and an actuator shortens the reciprocating member for a single upstroke after a prdetermined number of strokes of the reciprocating member to provide rejection of the defective article. In a second mode of operation, a predetermined number of articles are rejected upon every start-up of the apparatus to provide for rejection of questionable quality articles produced during start-up of the apparatus. In either mode of operation, the position of the variable length reciprocating stacking member can be determined by a proximity detector, to correctly time the lengthening or shortening of the variable length member.
