Thread supply device for textile machines

Claim 2

A thread supply device for textile machines for delivering thread unwound endwise from a fixed winding core (2,50a) comprising: a closed path track (22) having an inner opening greater than the maximum girth of said core and everything held on its winding space and free end and fixedly mounted coaxially adjacent to the free end of said core; running guide means (24) for guiding thread from said core out of further contact with said core in a revolving path spaced from said track and passing inside of said track, said running guide means being movably mounted to run freely on said track and adapted to by pulled around said track by thread (25) passing through said running guide means while being pulled axially away from said core, and a forward fixed thread guide (28,52) disposed on or near the axis of said core at a substantial distance beyond the free end thereof.

Claim 3

A thread supply device as defined in claim 1 comprising also: an axial channel (26) through said core for supply of thread to be wound on said core; a rotary winding head (19,20) having a winding eye (20) adapted to be propelled around the periphery of said core at its free end and driving means for said winding head for winding onto said core thread supplied through said axial channel; winding advance means (7,12,13,16...) associated with said core for advancing turns of thread wound on said core by said winding head axially away from said free end of said core, and means for interrupting the winding of thread on said core by said winding head after the winding produced as aforesaid reaches a predetermined maximum size until, as a result of unwinding as aforesaid, it thereafter reaches a predetermined minimum size; and in which, further, said closed path track has an enclosed opening of sufficient size for said running thread guide to lead thread being unwound from said core well clear of said winding head as well as of said track.

Claim 4

A thread supply device as defined in claim 2 in which said track is a circular ring track, in which also said running guide means is loosely mounted slidably thereon and in which the unwinding thread passes between said running guide means and the inner side of said ring track and thereafter through an eye located on said forward fixed thread guide.

Claim 5

A thread supply device as defined in claim 1 in which said track is a circular ring track and in which said running guide means is loosely mounted slidably thereon and has the basic form used for circulating runners in spinning or twisting machines.

Claim 6

A thread supply device as defined in claim 4 in which said running guide means (24a) is composed of two guiding portions (241) loosely engaged on said track (22) connected and spaced apart by a cross-tie (240). 6 A thread supply device as defined in claim 5 in which the inner side of said ring shaped track (22) has a channel groove (30) and means for supplying to said groove a thread conditioning material, such that said material may be applied to said unwinding thread.

Claim 7

A thread supply device as defined in claim 3 in which the inner side of said circular ring track (22) has a groove channel (30) and means associated therewith for supplying fluid dye to said channel, so that said unwinding thread may be dyed thereby.

Claim 8

A thread supply device as defined in claim 1 in which said running guide means (24) is arranged to guide a plurality of threads for delivery on a parallel path being pulled off said winding core.

Claim 9

A thread supply device for textile machines for delivering thread unwound endwise from a fixed storage winding core (2) comprising: a rotary winding head (19,20) having a winding eye (20) adapted to be propelled around the periphery of said core at the free end of said core; driving means for said rotary head including at least a shaft (7) rotatably mounted inside said core; a bore (26) through the length of said shaft for supplying thread to said winding eye; eccentrically driven means for advancing turns of thread wound on said core by said winding eye away from said free end of said core; means associated with said core for interrupting the winding of thread on said core by said rotary head and said winding eye when the winding of thread on said core reaches a first predetermined length until it thereafter is reduced to a second predetermined length; a ring track (22) surrounding and fully clearing the path of said rotary winding head and coaxially mounted in fixed relation to said core at its free end, and free-running thread guide means (24) on said ring track for leading thread being unwound from said core by a pull away from said core in an axial direction in a revolving path that is always clear of said rotary winding head as well as of said track.

Claim 10

A thread supply device for textile machines for delivering thread unwound endwise from a fixed storage winding core (2) comprising: a rotary winding head (19,20) having a winding eye (20) adapted to be propelled around the periphery of said core at the free end of said core; driving means for said rotary head including at least a shaft (7) rotatably mounted inside said core; a bore (26) through the length of said shaft for supplying thread to said winding eye; eccentrically driven means for advancing turns of thread wound on said core by said winding eye away from said free end of said core; means associated with said core for interrupting the winding of thread on said core by said rotary head and said winding eye when the winding of thread on said core reaches a first predetermined length until it thereafter is reduced to a second predetermined length; a ring track (22) surrounding and fully clearing the path of said rotary winding head and coaxially mounted in fixed relation to said core at its free end, and free-running thread guide means (24) on said ring track for leading thread being unwound from said core by a pull away from said core in an axial direction in a revolving path that is always clear of said rotary winding head as well as of said track.
