Abstract

Abstract A delivery device for running yarn with a winding body to which the thread feeds in the range of a conical extension for the formation of a rewinding stock, the latter being displaced rearwardly and removable over head. At least one stay is arranged in crossing overlapping relation to the extending of the angle channel between the conical extension and a winding body section connected thereto.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 205 words
A delivery device for running threads comprising a winding body defining a head end and having a concial extension and including means for feeding thread thereto in a range of said conical extension to form a thread winding stock which is displaceable in a direction away from said conical extension and being removable over the head end. said winding body having a winding body section connected to said conical extension and defining an angle channel extending in a circumferential direction between said conical extension and said winding body section, a plurality of stays circumferentially spaced around said winding body all of which simultaneously being adjustably disposed in crossing projecting overlapping arrangement relative to said angle channel, from a zero to a maximum crossing projecting overlapping arrangement, and means for fixedly adjusting said stays in position between said zero to said maximum crossing projecting overlapping arrangement relative to said angle channel, whereby the extent said stays project into said angle channel is adjustable to change the effective circumferential length of said angle channel for thread windings of the running threads thereon engaging all of the stays when the stays are adjusted to project into the angle channel forming slid-off thread sections of the thread windings thereon.
Claim 2
Dependent Claim 205 words
A delivery device for running threads comprising a winding body defining a head end and having a concial extension and including means for feeding thread thereto in a range of said conical extension to form a thread winding stock which is displaceable in a direction away from said conical extension and being removable over the head end. said winding body having a winding body section connected to said conical extension and defining an angle channel extending in a circumferential direction between said conical extension and said winding body section, a plurality of stays circumferentially spaced around said winding body all of which simultaneously being adjustably disposed in crossing projecting overlapping arrangement relative to said angle channel, from a zero to a maximum crossing projecting overlapping arrangement, and means for fixedly adjusting said stays in position between said zero to said maximum crossing projecting overlapping arrangement relative to said angle channel, whereby the extent said stays project into said angle channel is adjustable to change the effective circumferential length of said angle channel for thread windings of the running threads thereon engaging all of the stays when the stays are adjusted to project into the angle channel forming slid-off thread sections of the thread windings thereon.
Claim 3
Dependent Claim 23 words
The delivery device, as set forth in claim 1, wherein said plurality of said stays are aligned at corners of an equilateral polygon.
Claim 4
Dependent Claim 141 words
A delivery device for running threads comprising a winding body defining a head end and having a conical extension and including means for feeding thread thereto in a range of said conical extension to form a winding stock which is displaceable in a direction away from said conical extension and being removable over the head end, said winding body having a winding body section connected to said conical extension and defining an angle channel extending between said conical extension and said winding body section, and at least one stay disposed in crossing overlapping arrangement relative to said angle channel, said conical extension forming a frustoconical surface, said winding body section having a jacket surface which forms a drum wall, said at least one stay having one end which enters in said frustoconical surface, and another which enters in said drum wall.
Claim 5
Dependent Claim 141 words
A delivery device for running threads comprising a winding body defining a head end and having a conical extension and including means for feeding thread thereto in a range of said conical extension to form a winding stock which is displaceable in a direction away from said conical extension and being removable over the head end, said winding body having a winding body section connected to said conical extension and defining an angle channel extending between said conical extension and said winding body section, and at least one stay disposed in crossing overlapping arrangement relative to said angle channel, said conical extension forming a frustoconical surface, said winding body section having a jacket surface which forms a drum wall, said at least one stay having one end which enters in said frustoconical surface, and another which enters in said drum wall.
Claim 6
Dependent Claim 149 words
A delivery device for running threads comprising a winding body defining a head end and having a conical extension and including means for feeding thread thereto in a range of said conical extension to form a winding stock which is displaceable in a direction away from said conical extension and being removable over the head end, said winding body having a winding body section connected to said conical extension and defining an angle channel extending between said conical extension and said winding body section, at least one stay disposed in crossing overlapping arrangement relative to said angle channel, said winding body defining an axis, a carrier disposed in said winding body, said at least one stay being disposed in said carrier and inclined at an acute angle relative to said axis of said winding body, and means for adjusting said carrier in the axial direction of said winding body.
Claim 7
Dependent Claim 149 words
A delivery device for running threads comprising a winding body defining a head end and having a conical extension and including means for feeding thread thereto in a range of said conical extension to form a winding stock which is displaceable in a direction away from said conical extension and being removable over the head end, said winding body having a winding body section connected to said conical extension and defining an angle channel extending between said conical extension and said winding body section, at least one stay disposed in crossing overlapping arrangement relative to said angle channel, said winding body defining an axis, a carrier disposed in said winding body, said at least one stay being disposed in said carrier and inclined at an acute angle relative to said axis of said winding body, and means for adjusting said carrier in the axial direction of said winding body.
Claim 8
Dependent Claim 48 words
The delivery device, as set forth in claim 1, wherein said conical extension and said plurality of stays define angles of inclination, respectively, relative to an axis of said winding body, and said angles of inclination of said plurality of stays are smaller that of said conical extension.
Claim 9
Dependent Claim 36 words
