The present invention provides a method and apparatus for an improved beat-up system for beating up the weft threads into the fell of the fabric. The improved beat-up mechanism includes a plurality of spacer elements which are moved into and out of position between the warp threads for maintaining the spacing between the warp threads. The beat-up mechanism further includes a plurality of beat-up elements which are inserted into and out of position between the warp threads for beating up the weft threads onto the fell of the fabric. The beat-up elements also operate to maintain the spacing between the warp threads when the spacer elements are withdrawn from between the warp threads. In addition, the present invention discloses apparatus for increasing the spacing between adjacent groups of warp threads in the same plane so that weft-advancing arms or shed-retaining elements may be more easily inserted into the plane of the warp threads.
