Abstract
Abstract Apparatus for texturing synthetic thermoplastic yarn is in the form of a self-contained machine unit comprising a long straight support spline with which a drive transmission shaft is coextensive, the spline carrying at least one set of yarn feed rolls, a heater and a yarn texturing mechanism. The feed rolls are at one end of the spline and drivably connected to the transmission shaft, and at the other end of the spline a belt pulley also connected to the shaft can be belt coupled to a drive motor individual to the machine unit. Multiple machine units can be mounted in inclined spaced parallel disposition on a framework, as a horizontal row, to build a machine. The framework supports the motors for the machine units, and also optional setting apparatuses and winding assemblies associated with the machine units to form production units. Detachable spline extensions carry further feed rolls for co-operation with the first feed rolls for drawing yarn prior to texturing.

Claim 1
Independent Claim
103 words
Apparatus for texturing synthetic thermoplastic yarn, in the form of a machine unit comprising an elongate narrow linear support member providing a spline on which is mounted at least one yarn forwarding mechanism, yarn heating means, yarn texturing means and drive transmission means co-extensive with the spline, the yarn forwarding mechanism being located in the region of one end of the spline and being drivably connected with the drive transmission means, and a coupling element adapted for connection with a driving motor being located in the region of the other end of the spline and being drivably connected with the drive transmission means.
Claim 2
Dependent Claim
103 words
Apparatus for texturing synthetic thermoplastic yarn, in the form of a machine unit comprising an elongate narrow linear support member providing a spline on which is mounted at least one yarn forwarding mechanism, yarn heating means, yarn texturing means and drive transmission means co-extensive with the spline, the yarn forwarding mechanism being located in the region of one end of the spline and being drivably connected with the drive transmission means, and a coupling element adapted for connection with a driving motor being located in the region of the other end of the spline and being drivably connected with the drive transmission means.
Claim 3
Dependent Claim
66 words
Apparatus according to claim 1, and also including an auxiliary support member releasably secured to that end of the spline where the yarn forwarding means is located so as to form an extension of the spline, another yarn forwarding mechanism being mounted upon the spline extension and being drivably connected with the drive transmission means, the two yarn forwarding mechanisms together providng a yarn drawing system.
Claim 4
Dependent Claim
125 words
Machine for simultaneously texturing multiple synthetic thermoplastic yarns, comprising a framework providing a mounting for multiple removable individual machine units each comprising an elongate narrow linear support member providing a spline on which is Mounted at least one yarn forwarding mechanism, yarn heating means, yarn texturing means, and drive transmisson means co-extensive with the spline, the yarn forwarding mechanism being located in the region of one end of the spline and being drivably connected with the drive transmission means, and a coupling element being located in the region of the other end of the spline, and being drivably connected with the drive transmission means and also releasably drivably connected with an individual driving motor mounted on the framework adjacent said other end of the spline.
Claim 5
Dependent Claim
125 words
Machine for simultaneously texturing multiple synthetic thermoplastic yarns, comprising a framework providing a mounting for multiple removable individual machine units each comprising an elongate narrow linear support member providing a spline on which is Mounted at least one yarn forwarding mechanism, yarn heating means, yarn texturing means, and drive transmisson means co-extensive with the spline, the yarn forwarding mechanism being located in the region of one end of the spline and being drivably connected with the drive transmission means, and a coupling element being located in the region of the other end of the spline, and being drivably connected with the drive transmission means and also releasably drivably connected with an individual driving motor mounted on the framework adjacent said other end of the spline.
Claim 6
Dependent Claim
68 words
Machine according to claim 3, and including an auxilary support member which is releasably secured to that end of the spline where the yarn forwarding means is located so as to form an extension of the spline, another yarn forwarding mechanism being mounted on the spline extension and being releasably drivably connected with the drive transmission means, the two yarn forwarding mechanisms together providing a yarn drawing system.
Claim 7
Dependent Claim
66 words
Machine according to claim 3, wherein the machine units are mounted on the framework arranged in a horizontally extending row lying in a common upright plane, the splines of the machine units being parallel one with another and being inclined to the horizontal at an angle of about 10* to 60* so that the splines in the row overlap one another in their common upright plane.
Claim 8
Dependent Claim
21 words
