Abstract

Abstract A yarn conditioning plant for processing of yarn at high temperature is improved by provision of arrangements for enabling a plurality of yarn threads that have simultaneously been processed upon a single yarn transport to be wound individually upon separate spools. In accordance with a first preferred embodiment, a tension balancing means is provided which includes a potentiometer that is acted upon by the thread tension of yarn threads passing thereover so as to control the operating speed of individually driven spools. According to a further embodiment, the tension of the individual yarn threads is compensated by the use of two separate storage devices upon which the individual processed yarns can be separately wound in a manner so as to achieve a uniform tensioning thereof.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 174 words
Yarn conditioning plant comprising: (a) yarn supply means for holding a supply of yarn; (b) yarn conditioning chamber means for processing yarn at high temperature; (c) at least one yarn transport means for conveying yarn received from said yarn supply means through said yarn conditioning chamber means; (d) first transfer means associated with each of said transport means for removing a plurality of yarn threads from said yarn supply means and transferring the yarn threads to said associated yarn transport means; (e) second transfer means for removing said plurality of yarn threads from said yarn transport means; (f) spooler means for receiving said plurality of yarn threads from said second transfer means and for separately spooling each yarn thread; and (g) yarn tension balancing means for compensating for differences in tension between the tension of a first of said yarn threads and a second of said yarn threads, said yarn tension balancing means being positioned between said second transfer means and said spooler means, whereby a plurality of spools of uniform firmness are obtained.
Claim 2
Dependent Claim 174 words
Yarn conditioning plant comprising: (a) yarn supply means for holding a supply of yarn; (b) yarn conditioning chamber means for processing yarn at high temperature; (c) at least one yarn transport means for conveying yarn received from said yarn supply means through said yarn conditioning chamber means; (d) first transfer means associated with each of said transport means for removing a plurality of yarn threads from said yarn supply means and transferring the yarn threads to said associated yarn transport means; (e) second transfer means for removing said plurality of yarn threads from said yarn transport means; (f) spooler means for receiving said plurality of yarn threads from said second transfer means and for separately spooling each yarn thread; and (g) yarn tension balancing means for compensating for differences in tension between the tension of a first of said yarn threads and a second of said yarn threads, said yarn tension balancing means being positioned between said second transfer means and said spooler means, whereby a plurality of spools of uniform firmness are obtained.
Claim 3
Dependent Claim 45 words
Yarn conditioning plant according to claim 1, wherein said spooler means comprises a spooler associated with each yarn transport means, said spooler having at least two, individually driven spools, whereby two yarn threads can be processed upon a single yarn transport means and separately spooled.
Claim 4
Dependent Claim 41 words
Yarn conditioning plant according to claim 2, wherein said tension balancing means comprises a potentiometer means that is rotatable under the influence of the thread tension of yarn threads passing thereover for controlling the operating speed of said individually driven spools.
Claim 5
Dependent Claim 41 words
Yarn conditioning plant according to claim 3, wherein said potentiometer means is disposed on an axis of rotation of a double-armed lever and has rollers disposed at free ends of said lever and subject to the action of said thread tension.
Claim 6
Dependent Claim 25 words
Yarn conditioning plant according to claim 2, wherein the yarn tension balancing means comprise means for temporary separate storage of each of said yarn threads.
Claim 7
Dependent Claim 59 words
Yarn conditioning plant according to claim 5, wherein said yarn transport means includes a temporary yarn storage means and wherein the means for separate storage each comprise a common drive motor that is adjustable as a function of the fullness of said temporary storage means, said common drive motor being distinct from drive means associated with said spooler means.
Claim 8
Dependent Claim 27 words
Yarn conditioning plant according to claim 6, wherein the means for separate storage each comprise a photocell means for adjusting the drive motors of the spooler means.
Claim 9
Dependent Claim 106 words
Yarn conditioning plant according to claim 6 or 7, wherein said means for separate storage comprise a plurality of upper and lower conveyor belts, sliding panel means positioned between said upper conveyor belts at an upstream end thereof and extending from a position thereabove to a position thereunder for receiving a yarn thread from said second transfer means and storage slat means extending from a position between a downstream portion of said upper conveyor belts to a position therebeyond for temporarily retaining yarn thread layers thereon, and wherein said second transfer means comprises a winding arm means for winding said yarn thread about said conveyor belts.
Claim 10
Dependent Claim 52 words
Yarn conditioning plant according to claim 2 or 4 or 6, wherein said first transfer means comprises a winding arm, said winding arm being operable to execute circular movements about said yarn transport means, and wherein said yarn transport means comprise a plurality of upper and lower endless belts for yarn transport.
