Abstract
A loom comprising two sheets of warp threads which are momentarily held in diverging planes to form a weaving shed with a conveying tunnel for wefts, a blowing nozzle arranged in position at one side of such shed to propel wefts through such shed by means of a fluid discharged from said nozzle, and a main tensioning device arranged in position at the other side of such shed, operating with a fluid jet, to tension inserted wefts during the beating up movement of the loom. The jet is so arranged that it issues substantially, transversely, and freely across the conveying tunnel to suck in the weft and is caught by a passage disposed in alignment with said jet. An auxiliary tensioning device is provided and is constructed similarly to the main tensioning device. The auxiliary device is disposed at the side of the main device. The main and auxiliary devices are used for normal and startup operations, respectively, and each has gas or air pressure supply means for normal or startup operation.
