Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
174 words
Apparatus for continuously texturizing and cutting at least one multifiliment continuous yarn, wherein the yarn is texturized by fluid pressure, said apparatus comprising: an injecting device which includes at least one orifice for feeding said multifiliment yarn into the apparatus and one orifice for introducing a texturizing fluid; a cylindrical tube connected to the injecting device wherein the cylindrical tube has a constant cross-section and includes lateral orifices for exhausting the fluid and is connected at one end with the injecting device; a revolving spindle positioned in the cylindrical tube wherein the revolving spindle includes a rotating part adjacent the injection device wherein the rotating part is provided with an internal feed tube through which passes the multifiliment yarn and a fixed sleeve around which the yarn is wound to form a stuffed pack of yarn between the fixed sleeve and cylindrical tube; at least one cutting means for cutting the pack of yarn wound on the sleeve into a plurality of staple fibers, and means for stripping the staple fibers from the sleeve.
Claim 2
Dependent Claim
174 words
Apparatus for continuously texturizing and cutting at least one multifiliment continuous yarn, wherein the yarn is texturized by fluid pressure, said apparatus comprising: an injecting device which includes at least one orifice for feeding said multifiliment yarn into the apparatus and one orifice for introducing a texturizing fluid; a cylindrical tube connected to the injecting device wherein the cylindrical tube has a constant cross-section and includes lateral orifices for exhausting the fluid and is connected at one end with the injecting device; a revolving spindle positioned in the cylindrical tube wherein the revolving spindle includes a rotating part adjacent the injection device wherein the rotating part is provided with an internal feed tube through which passes the multifiliment yarn and a fixed sleeve around which the yarn is wound to form a stuffed pack of yarn between the fixed sleeve and cylindrical tube; at least one cutting means for cutting the pack of yarn wound on the sleeve into a plurality of staple fibers, and means for stripping the staple fibers from the sleeve.
Claim 3
Dependent Claim
67 words
Apparatus according to claim 1, wherein the spindle includes a first part having a slightly smaller diameter than the tube, and wherein the spindle includes a second part wider in diameter than the first part and positioned adjacent to the tube, said wider diameter part having a feed tube therein for introducing the yarn, said feed tube opening into a space between the spindle and the tube.
Claim 4
Dependent Claim
19 words
Apparatus according to claim 1, wherein the cutting means comprises a blade rotatable within a slot in the tube.
Claim 5
Dependent Claim
32 words
Apparatus according to claim 1, wherein at least a part of the spindle is mounted within the sleeve carried within the tube, and wherein the sleeve carries bearings for mounting the spindle.
Claim 6
Dependent Claim
37 words
Apparatus according to claim 1, wherein the means for removing the yarn comprise a rotatable wheel mounted in a space adjacent the end of the tube, and wherein the spindle extends beyond the end of the tube.
