A flat or circular loom produces a flat or tubular fabric in a multiplicity of web sections each served by an individual weaving unit including a weft needle whose thread, after traversing the shedded warp threads of the associated section, is engaged by the weft thread of an adjoining needle whereby an interlinked chain of weft loops is formed to act as a filling. An intermittently operable thread clamp prevents a contraction of a loop prior to its engagement by the next weft needle and, especially in a flat loom, may also be used to draw the node between two loops into the fabric of the preceding section. In a circular loom, a loop inverter associated and synchronized with each weft needle causes the cross-links between the nodes of adjacent tiers to come to lie on the inside of the tubular fabric. |
