Abstract
A device for tensioning and drawing back warp yarns brought from a creel to a weaving machine. The tensioning and drawing back device keeps tension and if necessary draws back warp yarns (,) led from a bobbin (,) to a weaving machine. A supporting body (,) has a curved friction surface to support the warp yarn (,) between the bobbin (,) and the weaving machine. A first (,) and a second tensioning element (,) exert a tensile force on the warp yarn (,), respectively, in front of and behind the curved friction surface (,). The tensioning elements (,), (,) can be suspended from the warp yarn (,) and for example only through their own weight may exert this tensile force. This device easily draws back the warp yarn (,) out of the weaving area. The replacement of a bobbin (,) occurs without interruption or disturbance of the weaving process.
