ABSTRACT:
A device for quickly sewing finishing elements such as edgings and collars onto knitted outerwear articles to be applied on chainstitch sewing machines comprises: (a) a braking member for the finishing element effective to maintain it in a tensioned or stretched condition; (b) a folding or bending member effective to fold or bend said finishing element, and (c) a feeding member effective to feed the folded or bent finishing element and the knitted article, under the foot of the sewing machine. The braking member is formed by a curved rod, onto the bottom of which presses a blade spring, and by two parallel vertical rods located upstream of the first rod, the finishing element passing at first between said two rods and then, together with the selvedge, between the curved rod and blade spring. The pressure exerted by the blade spring on the rod may be adjusted by a screw provided with a spring.
