Abstract
Abstract An automatic winding machine having a carrier for rotatably supporting a plurality of winding supports and rotatable to move the winding supports in an arcuate path intersecting a delivery path along which yarn to be wound is supplied by a pneumatic transport tube assembly, the pneumatic transport tube assembly having a transport tube with a longitudinal slit therein such that as a winding support is moved from a mounting station to a winding station over the arcuate path, the yarn to be wound is caught by the winding support and moved through the longitudinal slit. The winding supports are held on the carrier by gripping mechanisms having flanges axially slidable to grip an empty winding support at a mounting station and release a full winding support at a removing station such that winding of continuously delivered yarn can be accomplished automatically without requiring manual intervention.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
191 words
An automatic winding machine for winding textile yarn continuously delivered at high speed, comprising: pneumatic means including a first transport tube with a longitudinal slit therein and a second transport tube axially aligned with and spaced from said first transport tube for supplying yarn along a delivery path from a supply zone to a waste zone, said space being sufficient to permit passage therethrough of an empty yarn winding support; rotatable carrier means for rotatably supporting a plurality of yarn winding supports spaced about the rotatable axis of the carrier means, means for rotating said carrier means to move said yarn winding supports individually to a winding station along an arcuate path intersecting said delivery path at the space between said first and second transport tubes, such that movement of a yarn winding support to said winding station moves the yarn to be wound through said longitudinal slit in said transport tube, and brings the yarn in contact with yarn engaging means adjacent said winding support; and drive means for rotating a yarn winding support at said winding station and for distributing the yarn longitudinally along a rotating yarn winding support.
Claim 2
Dependent Claim
191 words
An automatic winding machine for winding textile yarn continuously delivered at high speed, comprising: pneumatic means including a first transport tube with a longitudinal slit therein and a second transport tube axially aligned with and spaced from said first transport tube for supplying yarn along a delivery path from a supply zone to a waste zone, said space being sufficient to permit passage therethrough of an empty yarn winding support; rotatable carrier means for rotatably supporting a plurality of yarn winding supports spaced about the rotatable axis of the carrier means, means for rotating said carrier means to move said yarn winding supports individually to a winding station along an arcuate path intersecting said delivery path at the space between said first and second transport tubes, such that movement of a yarn winding support to said winding station moves the yarn to be wound through said longitudinal slit in said transport tube, and brings the yarn in contact with yarn engaging means adjacent said winding support; and drive means for rotating a yarn winding support at said winding station and for distributing the yarn longitudinally along a rotating yarn winding support.
Claim 3
Dependent Claim
92 words
An automatic winding machine as recited in claim 1 and further comprising means disposed downstream of said winding station for removing full yarn winding supports from said carrier means, and means disposed upstream of said winding station for mounting empty yarn winding supports on said carrier means, such that an empty yarn winding support is mounted on said carrier means by said mounting means, moved to said winding station by said carrier means for winding of yarn therearound and moved after winding for removal from said carrier means by said removing means.
Claim 4
Dependent Claim
34 words
An automatic winding machine as recited in claim 2 wherein said drive means includes a pivotally mounted winder assembly having a winding roll engaging a yarn winding support and a reciprocating yarn guide mechanism.
Claim 5
Dependent Claim
39 words
An automatic winding machine as recited in claim 2 wherein said carrier means includes opposing end plates rotatable about a horizontal axis and a plurality of gripping mechanisms carried by said end plates for mounting the yarn winding supports.
Claim 6
Dependent Claim
103 words
An automatic winding machine as recited in claim 4 wherein said gripping mechanisms include a paiR of axially aligned flanges, each of said flanges being slidably mounted on one of said end plates, said removing means sliding said flanges apart to release a full yarn winding support and including a chute for discharging a full yarn winding support released by said flanges, and said mounting means includes a magazine for storing a plurality of empty yarn winding supports and loader means for moving an empty yarn winding support from said magazine to be gripped by said flanges of one of said gripping mechanisms.
Claim 7
Dependent Claim
55 words
An automatic winding machine as recited in claim 5 wherein said carrier means includes control means for rotating said end plates a predetermined distance to move an empty yarn winding support from said mounting means to said winding station and for maintaining said end plates stationary until the empty yarn winding support is fully wound.
Claim 8
Dependent Claim
48 words
An automatic winding machine as recited in claim 6 wherein said gripping mechanisms are spaced, such that when one gripping mechanism is disposed at said winding station, a second gripping mechanism is disposed adjacent said removing means and a third gripping mechanism is disposed adjacent said mounting means.
Claim 9
Dependent Claim
35 words
An automatic winding machine as recited in claim 7 and further comprising means disposed along said arcuate path to engage said gripping mechanisms and rotate the yarn winding supports before they reach said winding station.
