ABSTRACT:
The invention provides a feeding unit for a metallic linear material having an irregular shaped section applicable to a continuous manufacturing apparatus for a fastener stringer, the feeding unit comprising the seventh and eighth rollers rotatably supported at their fixed positions, the ninth and tenth rollers opposing the seventh and eighth rollers and rotatably supported at both ends of a movable roller support member, wherein the roller support member is rotatably supported around its center and urged elastically in a direction perpendicular to a straight line connecting the centers of roller shafts of the seventh and eighth rollers, thereby the feeding roller protecting the metallic linear material from easily slipping out of feeding rollers, returning the linear material to its original track immediately even if the linear material slips out for a while, and feeding the metallic linear material stably and securely without damaging the linear material or ratchet wheel.
