The present yarn tension control device is adaptable for regulating and adjusting the tension being applied to a running yarn being fed along a predetermined path of travel. The device includes first and second plate members having adjacent inner faces positioned on opposite sides of the running yarn with one of the plate members being resiliently urged toward the other plate member and in engagement with one side of the running yarn to thereby apply tension to the running yarn passing therebetween. The inner face of one of the plate members is substantially smooth and flat while the other plate member is provided with an opening extending through the central portion and the inner face is provided with shallow grooves extending radially outwardly from and being communicatively connected with the opening. The opening and the grooves in the plate member cooperate to provide passageways for the passage of air and for the escape of lint from between the plate members.
