Abstract
In the case of a paraffin waxing device for a travelling yarn, a rotating paraffin body is weighted in axial direction against a stopping face. The stopping face lies against the front surface of the paraffin body, over which the travelling yarn is guided. During the waxing process, undesired rubbing off of paraffin particles can soil the feed material or the machine elements. According to the invention, the stopping face is rolled on the rotating front surface. The rubbing-off of paraffin particles, in particular in the area of the stopping face, is hereby avoided.
Claims22
A device for waxing a travelling yarn, comprising:
- a carrier member carrying a wax body and attached to means for rotatably driving said wax body with said driving means being independent of the frictional force between the wax body and the yarn on said wax body during waxing operation,
- abutting means attached to holding means of said means for rotatably driving for abutting the wax body at a front surface of said wax body protruding from said holding means, and
- means for resiliently pressing said wax body against said abutting means, said means for resiliently pressing located between said carrier member and said driving means,
- wherein said abutting means includes at least one rotatably driven abutting element which is abutting the wax body front end surface and wherein said rotatable driven abutting element is frictionally driven by said rotatable driven wax body.
Yarn waxing apparatus comprising a support member:
- a wax body holder comprised of a carrier for holding a wax body, said carrier being mounted on a drive means mounted on a shaft for rotatable movement, said shaft being attached to said holder,
- a drive mechanism attached to said drive means for positively rotating said carrier independently of the frictional force between the yarn being waxed and the wax body when operated to wax yarn,
- an abutment member attached to said support member engaging an axial end surface of said wax body,
- and a resilient spring biasing said carrier and thereby said wax body against said abutment member,
- wherein said abutment member is frictionally rotated by engagement with the wax body during waxing operations.
