ABSTRACT:
A yarn tension device is illustrated wherein a concave arcuate surface defines an indentation extending across and below a yarn channel forming an arcuate interruption in the yarn channel for receiving an arcuate rotatable element for rotation by the yarn as it moves through the yarn channel. It is further contemplated that a housing provide an upright receptacle for receiving a number of rotatable elements for rotation by the yarn utilizing the force required to rotate the rotatable elements for tensioning the yarn. A number of receptacles receiving rotatable elements may be provided in spaced aligned relation to vary the amount and mode of tension application. A side opening yarn entrance passageway is contemplated for self-threading the yarn beneath a rotatable element.
