ABSTRACT:
Apparatus for removing a fill yarn from a web of warp tows advances the web lengthwise across a tabletop having opposite pairs of bars at the leading edge thereof for separating the outermost tow at each of the opposite edges of the web from the remaining tows within the web. Rotatable cutting wheels which are resiliently urged against the top of a rotating shaft at the underside of the web sever the fill yarn between the outermost tows and the remaining tows of the web to form separate fill yarn lengths extending across the width of the web. As the advancing web is then divided along a central portion thereof, the separate lengths of fill yarn are removed by a hook mounted within a central portion of the tabletop and reciprocating between positions above and below the tabletop so as to hook each separate length of fill yarn and begin pulling it down through the tabletop. As each length of fill yarn is pulled down through the tabletop by the hook, it is engaged by a pair of opposing rollers and pulled into the inside of a hollow duct where an air stream carries the length of fill yarn away for disposal.
