ABSTRACT:
An improved device is disclosed for tensioning a running length of textile yarn. The device has a housing with a yarn passageway extending therethrough. An annular seat is provided in the passageway to receive a spherical element, the surface around the annulus having a radius of curvature upwardly and outwardly therefrom. An upper end of the yarn passageway is provided with an abrasion resistant surface having smooth rounded edges at termination of the passageway, and may be in the form of an insert into the housing or an integral part of the housing. At least one spherical element is receivable in the passageway and resideable at the seat. The spherical element is out of contact with walls defining said passageway when at rest on the seat. One embodiment of the invention includes at least one spherical element in the passageway and a further, larger spherical element that resides atop the passageway, in engagement with the abrasion resistant surface thereat. The housing, seat and abrasion resistant upper end surface may be of integral construction. Further, a collar may be removably received around the housing with an arm secured thereto and extending across at least a portion of the passageway to prevent egress of the spherical element without adversely affecting tension on or condition of the yarn. Mounting means may also be provided for securing the device to a yarn handling machine.
