Abstract
Abstract Method of and apparatus for producing finished open-end yarn in a spinning chamber. A finishing material, for instance dyestuff, is fed into the spinning chamber, which is provided with a collecting surface for depositing fiber and with a take-off opening for taking-off yarn. The finishing material, for instance dyestuff, is applied to the yarn between the collecting surface and the take-off opening by friction of the yarn against a rotating application surface, the dyeing-through of the yarn being accomplished by penetration of twists of the yarn in the direction towards the collecting surface.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
59 words
A method for producing finished open-end yarn in a spinning chamber, comprising supplying a finishing material, into the chamber providing the chamber with a collecting surface for the depositing of fibers and with a take-off opening for taking-off yarn, and applying the finishing material to the yarn between the collecting surface and the take-off opening of the spinning chamber.
Claim 2
Independent Claim
59 words
A method for producing finished open-end yarn in a spinning chamber, comprising supplying a finishing material, into the chamber providing the chamber with a collecting surface for the depositing of fibers and with a take-off opening for taking-off yarn, and applying the finishing material to the yarn between the collecting surface and the take-off opening of the spinning chamber.
Claim 3
Dependent Claim
44 words
The method as in claim 1, comprising applying the finishing material to the yarn by the friction of the yarn against a rotating application surface, and dyeing-through the yarn by the penetration of twists of the yarn in the direction towards the collecting surface.
Claim 4
Dependent Claim
58 words
Apparatus for producing finished open-end yarns, comprising a spinning chamber with a collecting surface and a take-off opening and having an application surface between said collecting surface and take-off opening, the formed yarn being brought against the application surface, and at least one jet for supplying the finishing material, said jet being disposed opposite to said application surface.
Claim 5
Dependent Claim
58 words
Apparatus for producing finished open-end yarns, comprising a spinning chamber with a collecting surface and a take-off opening and having an application surface between said collecting surface and take-off opening, the formed yarn being brought against the application surface, and at least one jet for supplying the finishing material, said jet being disposed opposite to said application surface.
Claim 6
Dependent Claim
36 words
Apparatus as in claim 3, comprising ventilation channels in the chamber, and wherein the application surface is disposed on a wall of the spinning chamber between the collecting surface and the mouths of the ventilation channels.
Claim 7
Dependent Claim
17 words
Apparatus as in claim 4, wherein at least one distribution groove is provided on the application surface.
Claim 8
Dependent Claim
23 words
Apparatus as in claim 3, wherein the jet is part of an ejector system exposed to the suction effect of the spinning chamber.
Claim 9
Dependent Claim
39 words
Apparatus as in claim 3, wherein the application surface merges, in the direction toward the collecting surface, into an off-sprinkling groove communicating with the space surrounding the external part of the spinning chamber via at least one off-sprinkling channel.
Claim 10
Dependent Claim
23 words
Apparatus as in claim 7, wherein the off-sprinkling channel terminates opposite to the baffle wall, with a collecting channel below said baffle wall.
Claim 11
Dependent Claim
30 words
Apparatus as in claim 3, comprising a distribution tank which is in turn connected to a central tank for the finishing material, said jet being connected to said distribution tank.
Claim 12
Dependent Claim
19 words
Apparatus as in claim 7, wherein the off-sprinkling channel is connected to the distribution tank via a dischargE channel.
Claim 13
Dependent Claim
15 words
Apparatus as in claim 9, wherein the central tank is provided with a mixing device.
Claim 14
Dependent Claim
15 words
Apparatus as in claim 9, wherein the distribution tank is provided with a mixing device.
Claim 15
Dependent Claim
16 words
Apparatus as in claim 9, wherein the central tank is provided with an adjustable heating element.
Claim 16
Dependent Claim
16 words
Apparatus as in claim 9, wherein the distribution tank is provided with an adjustable heating element.
