Pull tab loading apparatus of slide fastener slider assembling machine

A pull tab loading apparatus in a slide fastener slider assembling machine, comprising:

• (a) a pull tab chute sloping from an upstream end to a downstream end and having a chute groove for receiving pull tabs longitudinally lined up in a row;
• (b) a pull tab pushing unit having in a base a horizontally extending pull tab guide groove which faces at one end of a pair of side guide plate of the slider assembling machine and communicates with said chute groove at a downstream end thereof, said guide groove having a center line in a vertical plane in which a center line of said chute groove exists, said pushing unit including a pull tab pusher slidably received in said guide groove for reciprocating movement between said downstream end of said chute groove and the inlet port of the slider assembling machine so as to successively move the pull tabs, one by each forward stroke, into the inlet port of the slider assembling machine;
• and
• (c) a contact pin rotatably located upwardly of said base adjacently to said downstream end of said chute groove of said chute for engagement with an upper surface of the pull tab being fed from said downstream end of said chute groove to said guide groove in an inclined posture.
