ABSTRACT:
A tensioning unit for breakage-prone or rupture-sensitive warp threads in a weaving loom is constructed to avoid a torque responsive characteristic that gently tension the warp threads. For this purpose the tensioning unit is equipped with a torque moment compensation arrangement for compensating non-symmetric loading of a smoothing roller (10). A hollow guide roller (11) carried on rigidly mounted levers (9) has mounted inside the guide roller a rotatable stabilizing shaft (18), which in turn is operatively connected to the smoothing roller (10) through plates (19), so that the smoothing roller itself is supported by spring-loaded levers (8).
