Claim 10

The apparatus of claim 2, wherein said resistance means comprises a tubular member, at least partially curved to define an arcuate path portion of wad passage therethrough, with the interior of said tubular member comprising surface means offering resistance to but permitting the passage of a wad of crimped yarn therethrough, including means for delivering steam at sufficient temperature and pressure to both heat set the yarn crimps and move the yarn through the needle member and move the crimped yarn wad through the tubular member, with yarn supply means for delivering yarn to the inlet of the needle member, and including crimped yarn takeup means for taking up yarn in de-wadded form upon discharge thereof from said tubular member.

Claim 11

The apparatus of claim 9, including means for cooling de-waddeD yarn upon discharge from said tubular member, but upstream of said yarn takeup means.

Claim 12

The apparatus of claim 2, wherein said resistance means comprises a rotatable roll member and means for rotating the same, with the surface of said roll member being adapted to receive said wad and deliver yarn therefore in de-wadded form along an arcuate path, including means for delivering steam at sufficient temperature and pressure to both heat set the yarn crimps and to move the yarn through the needle member.

Claim 13

The apparatus of claim 11, including means for applying heat of relaxation of de-wadded yarn downstream of the path of movement of yarn delivered from said roll member and means defining a path of movement of yarn delivered from said roll member, with yarn supply means for delivering yarn to the inlet of the needle member, and including crimped yarn takeup means for taking up yarn in de-wadded form upon discharge thereof from past said means for applying heat of relaxation.

Claim 14

The apparatus of claim 12, including means for cooling de-wadded yarn during its movement along its path, downstream of said means for applying said heat of relaxation, but upstream of said takeup means.

Claim 15

The apparatus of claim 1, wherein said resistance means comprises a tubular member, at least partially curved to define an arcuate path portion of wad passage therethrough, with the interior of said tubular member comprising surface means offering resistance to, but permitting the passage of, a wad of crimped yarn therethrough.

Claim 16

The apparatus of claim 14, wherein said tubular member is of J-box construction.

Claim 17

The apparatus of claim 14, including external means for heating said tubular member.

Claim 18

The apparatus of claim 16, wherein said heating means comprises a steam jacket.

Claim 19

The apparatus of claim 1, wherein said resistance means comprises a rotatable roll member and means for rotating the same, with the surface of said roll member being adapted to receive said wad and deliver yarn therefrom in de-wadded form along an arcuate path.

Claim 20

The apparatus of claim 18, wherein said roll member is of fluted surface construction.

Claim 21

The apparatus of claim 18, including means for applying heat of relaxation of de-wadded yarn downstream of the path of movement of yarn delivered from said roll member and means defining path of movement of yarn delivered from said roll member.

Claim 22

The apparatus of claim 20, wherein said means defining a path of movement comprises an endless conveyor belt of metal mesh construction, disposed for receiving yarn from said roll member.

Claim 23

Apparatus for facilitating the texturing of yarn delivered thereto, comprising a needle member having a longitudinal yarn path extending therethrough between an inlet and an oulet thereof, said yarn path terminating at its outlet end in a yarn crimping chamber means, said crimping chamber means being of a greater transverse size than the inlet end of said yarn path for accommodating a wad of crimped yarn therein, said crimping chamber means having yarn wad outlet end opening in a downstream direction relative to the travel of yarn, and combination means for facilitating both heating yarn being delivered through the path in the needle and impelling yarn therethrough from a plurality of longitudinally spaced locations along the path through the needle, wherein said combination means comprises a housing disposed about said needle member defining a chamber about a substantial longitudinal portion of the outer wall portions thereof, inlet means to said chamber for facilitating the delivery of steam thereto, and a plurality of connecting ducts extending through the wall portions of said needle member between said chamber and said yarn path, with said ducts being angled through the wall portions of said needle member to intersect the path of uncrimped yarn extending therethrough at locations more closely adjacent to the outlet of the needle member than the locations of communication of said connecting ducts with said chamber.

Claim 24

Apparatus for facilitating the texturing of yarn delivered thereto, comprising a needle member having a longitudinal yarn path extending therethrough between an inlet and an oulet thereof, said yarn path terminating at its outlet end in a yarn crimping chamber means, said crimping chamber means being of a greater transverse size than the inlet end of said yarn path for accommodating a wad of crimped yarn therein, said crimping chamber means having yarn wad outlet end opening in a downstream direction relative to the travel of yarn, and combination means for facilitating both heating yarn being delivered through the path in the needle and impelling yarn therethrough from a plurality of longitudinally spaced locations along the path through the needle, wherein said combination means comprises a housing disposed about said needle member defining a chamber about a substantial longitudinal portion of the outer wall portions thereof, inlet means to said chamber for facilitating the delivery of steam thereto, and a plurality of connecting ducts extending through the wall portions of said needle member between said chamber and said yarn path, with said ducts being angled through the wall portions of said needle member to intersect the path of uncrimped yarn extending therethrough at locations more closely adjacent to the outlet of the needle member than the locations of communication of said connecting ducts with said chamber.
