ABSTRACT:
A lamellae comb comprises a carrier or support and lamellae or small plates arranged thereupon which contain lateral projections serving as shed-retaining elements for the warp threads. Each shed-retaining element is formed by a respective projection at the two lamellae enclosing the shed-retaining element. The projections protrude towards each other, conjointly bridge the intermediate space between the lamellae and are mutually offset in the warp direction. Thus, the tube width may be adjusted within wide limits without the lamellae containing the projections having to be exchanged. The lamellae are positioned on the carrier or support by means of racks resiliently supported at the carrier and extending over the weaving or fabric width. The teeth of the racks position the lamellae and have a tooth division or pitch corresponding to the desired tube width of the lamellae. Thus, the lamellae division or pitch does not exhibit any error across the entire weaving width, particularly no summation error, and the lamellae combs can be exactly reproduceably manufactured.
