This application relates to an apparatus for winding strandular material known in the textile industry as a takeup device. The overall arrangement of the device incorporates a stationary supporting spindle onto which a rotatable package support is mounted for receipt of strandular material wound thereon. The support and the strandular material wound thereon as the package is progressively built, is adapted for contact with a rotatable drive drum. A traverse device to guide the strandular material to the rotatable package and control the manner in which the strandular material is wound thereon is also included. Both the drive means and the traverse means including the motors therefor are mounted on a freely vertical movable carriage supported within a frame member and uniquely counterbalanced by a pulley suspended counterweight system. The spindle and the package support are mounted on said frame independent of such carriage. The drive and traverse means are thus free to move upwardly while the package progressively builds on the stationary spindle. Initial pressure means are further included to apply an initially higher pressure between the drive means and the package support to prevent skidding during the required acceleration of the support to its operational winding speed. Additionally, differential pressure means are included to progressively decrease the amount of drive pressure between the drive drum and the package as the package builds.

Winding apparatus

This application relates to an apparatus for winding strand onto a rotating member to form a package including means for traversing the strand axially of the member to form a plurality of layers thereover. A novel manner for supporting the traversing means while permitting such to oscillate so as to scatter the point at which the strand is laid down at opposite ends of the package and novel means for adjusting the stroke of such oscillation during machine operation are disclosed.

Strand scattering winding machine

Disclosed herein is mechanism for lubricating the traverse portion of winding apparatus. The lubricating mechanism includes an atomizing system for introducing an oil mist into a housing which generally encloses a traverse cam mounted for rotation on suitable bearings within the housing. The oil mist is effective to lubricate the various parts of the traverse system notwithstanding that the traverse cam may be rotating at speeds of 7,000 r.p.m. and higher. The housing enclosing the traverse cam is provided with a slot through which a strand guide, attached to a cam follower, projects. The cam follower is engaged in an endless groove in the traverse cam and as the traverse cam is rotated the guide is reciprocated from end to end of the traverse cam groove and is thus operable to distribute an advancing strand with which it is engaged onto a rotating package. The oil mist is precluded from escaping through the slot in the housing by means of an impeller which operates to create a zone of negative pressure within the traverse cam housing. By such construction the oil mist is drawn to a sump area within the housing and directionally away from the traverse slot. Thus, effective lubrication of the traverse mechanism and associated parts is achieved while any substantial escape of the oil mist through the traverse slot is precluded.

Traverse cam lubrication

The instant invention relates to a belt driven traverse for reciprocating a running strand of yarn in a winding machine. Said traverse means comprises a timing type belt travelling in a closed path around two sprockets and which carries and reciprocates a yarn guide longitudinally of a winding package. Means are associated with said yarn guide to prevent rotary motion thereof as it is carried around said closed path.
