Abstract
Articles (12) made by winding of filamentary material (11), such as yarn and thread, are especially suitable for providing brushes and pile weatherstripping. In order to enable the yarn (11) to be unwound and payed out of spools (24) disposed in a stationary or static array, the yarn is fed from the spools (24) through a rotating spindle (30). A frame (14) located at the beginning of the path and may be provided by laterally spaced pairs of wire (52) which travel around posts (36) provided by rollers on a stationary bracket (38). In order to support the bracket (38) and the frame (14), a shaft (28) reciprocates a pair of support rods (100, 102) in synchronism with the rotation of the spindle (30). Bindings (60, 62) are applied to the ends of the loops (54) as they leave the winding station (14). Slitters (20) divide the loops (54).
