Abstract
A tensioning device of a loom is embodied by a tensioning element rotatably mounted on a plurality of rollers which, in turn, are supported at spaced apart bearing places on a drive shaft. The drive shaft is biased by a torsion bar acted on its end by an adjusting mechanism driven by means of an eccentric. The tensioning device comprises a reduced number of parts of reduced dimension and can therefore adapt very rapidly to changes in the position of the warp yarns. The tensioning device is particularly suitable for high-speed looms which process delicate warp yarns.
