ABSTRACT:
A beat-up mechanism for a weaving loom includes a relatively movable indexing reed and beat-up reed adjacent each other and arranged to transport weft threads adjacent the fell of the fabric and then beat-up the weft threads into the fell by means of beat-up fingers inserted between warp threads. The indexing and beat-up reeds each are constructed as modular units and include multiple, parallel fingers having narrow tip portions and wider root portions, whereby the wider root portions of one reed maintain the warp threads spaced apart for insertion of the tip portions of the other reed during weft transfer. The indexing and beat-up reeds are particularly useful in a multi-shed weaving loom wherein multiple sheds are progressively moved toward the fell of the fabric during the weaving operation with insertion of a pick in each shed. The indexing and beat-up reeds, moreover, include a guiding arrangement whereby the reeds are positively maintained in lateral alignment during weft transfer and beat-up.
