Abstract

Abstract A take-up winder for undrawn spun yarn is set up on a floor, while a yarn-drawing machine is installed under the floor. The floor is provided with an opening through which the undrawn yarn loaded upon a creel, which is set up substantially on the same level as said floor, is supplied to the yarn-drawing machine under the floor.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 241 words
In apparatus for handling undrawn spun yarn in a synthetic yarn producing mill, the combination of a spinning machinery, a creel truck, a yarn-drawing machine, and a floor; said spinning machinery having a plurality of take-up winders set up on said floor and adapted to wind up undrawn spun yarn on bobbins; said creel truck being provided with a plurality of bobbin supports for packages of the undrawn spun yarn wound on said bobbins; said yarn-drawing machine being installed under said floor and having a plurality of drawing units adapted to stretch said yarn on said creel truck; and said floor comprising a first floor section where the packages of the undrawn spun yarn are removed from said take-up winder and loaded on said bobbin supports on said creel truck, a second floor section where said creel truck is arranged to supply the undrawn spun yarn to said yarn-drawing machine, said second floor section being substantially communicated with said first floor section and arranged along the lengthwise direction of said yarn-drawing machine, and a third floor section forming an opening surrounded by said first and second floor sections to allow the undrawn spun yarn unwound from said packages on said creel truck to pass therethrough and to be supplied to each of said drawing units of said yarn-drawing machine installed under said floor, said opening being parallel to the lengthwise direction of said yarn-drawing machine and being above said drawing units.
Claim 2
Dependent Claim 241 words
In apparatus for handling undrawn spun yarn in a synthetic yarn producing mill, the combination of a spinning machinery, a creel truck, a yarn-drawing machine, and a floor; said spinning machinery having a plurality of take-up winders set up on said floor and adapted to wind up undrawn spun yarn on bobbins; said creel truck being provided with a plurality of bobbin supports for packages of the undrawn spun yarn wound on said bobbins; said yarn-drawing machine being installed under said floor and having a plurality of drawing units adapted to stretch said yarn on said creel truck; and said floor comprising a first floor section where the packages of the undrawn spun yarn are removed from said take-up winder and loaded on said bobbin supports on said creel truck, a second floor section where said creel truck is arranged to supply the undrawn spun yarn to said yarn-drawing machine, said second floor section being substantially communicated with said first floor section and arranged along the lengthwise direction of said yarn-drawing machine, and a third floor section forming an opening surrounded by said first and second floor sections to allow the undrawn spun yarn unwound from said packages on said creel truck to pass therethrough and to be supplied to each of said drawing units of said yarn-drawing machine installed under said floor, said opening being parallel to the lengthwise direction of said yarn-drawing machine and being above said drawing units.
Claim 3
Dependent Claim 46 words
Apparatus as claimed in claim 1, wherein said opening of said third floor section consists of a pair of elongated openings the length of each of which is substantially equal to the sum of intervals between adjacent drawing units on one side of said yarn-drawing machine.
Claim 4
Dependent Claim 64 words
Apparatus as claimed in claim 1, wherein said opening of said third floor section consists of openings formed at both sides of a top frame surface of said yarn-drawing machine as said top frame surface thereof locates at the center of a relatively wide elongated opening made through said floor; and said second floor section is said top frame surface of said yarn-drawing machine.
Claim 5
Dependent Claim 25 words
Apparatus as claimed in claim 1, wherein said opening of said third floor section consists of a plurality of independent holes made through said floor.
Claim 6
Dependent Claim 34 words
Apparatus as claimed in claim 1, wherein guide stands for undrawn spun yarn unwound from said bobbin supports of said creel truck on said second floor section are provided in adjacent to said opening.
Claim 7
Dependent Claim 59 words
Apparatus as claimed in claim 1, wherein said creel truck is a balance truck which comprises said wheels mounted to fixed bearings and front and rear wheels mounted to swivEllable bearings, said fixed bearings being longer than said swivellable bearings; and said first floor section comprises a pair of guide rails by which said creel trucks are forcedly aligned.
Claim 8
Dependent Claim 28 words
Apparatus as claimed in claim 6, wherein each of said creel trucks comprises a coupling means by which a plurality of the creel trucks are organized and aligned.
Claim 9
Dependent Claim 16 words
Apparatus as claimed in claim 7, further comprising a tractor for pulling said organized creel trucks.
Claim 10
Dependent Claim 255 words
In a system comprising a spinning machinery having a plurality of take-up winders adapted to wind up the undrawn spun yarn on bobbins, a creel provided with a plurality of bobbin supports for packages of the undrawn spun yarn wound on said bobbins, and a yarn-drawing machine having a plurality of drawing units adapted to stretch said yarn on said creel; said take-up winder being set up on a floor under which said yarn-drawing machine is installed; said creel being integral with a truck which is movable to any desired direction; said truck being transferred by a driving means to floor sections comprising a first loading floor section adjacent to said take-up winder where said packages of undrawn spun yarn are removed from said take-up winder and loaded on said bobbin supports of said creel, a second arranging floor section where said trucks are aligned to supply said undrawn yarn to said drawing machine under said floor, said second floor section substantially being communicated with said first floor section and arranged along the lengthwise direction of said drawing machine, and an opened third floor section surrounded by said first and second floor sections and allowing said undrawn spun yarn unwound from said packages on said trucks aligned on said second floor section to pass through an opening of said third floor section to be supplied to each of said drawing units of said yarn-drawing machine under said floor, said opening being parallel to the lengthwise direction of said yarn-drawing machine and being above the latter.
Claim 11
Dependent Claim 255 words
In a system comprising a spinning machinery having a plurality of take-up winders adapted to wind up the undrawn spun yarn on bobbins, a creel provided with a plurality of bobbin supports for packages of the undrawn spun yarn wound on said bobbins, and a yarn-drawing machine having a plurality of drawing units adapted to stretch said yarn on said creel; said take-up winder being set up on a floor under which said yarn-drawing machine is installed; said creel being integral with a truck which is movable to any desired direction; said truck being transferred by a driving means to floor sections comprising a first loading floor section adjacent to said take-up winder where said packages of undrawn spun yarn are removed from said take-up winder and loaded on said bobbin supports of said creel, a second arranging floor section where said trucks are aligned to supply said undrawn yarn to said drawing machine under said floor, said second floor section substantially being communicated with said first floor section and arranged along the lengthwise direction of said drawing machine, and an opened third floor section surrounded by said first and second floor sections and allowing said undrawn spun yarn unwound from said packages on said trucks aligned on said second floor section to pass through an opening of said third floor section to be supplied to each of said drawing units of said yarn-drawing machine under said floor, said opening being parallel to the lengthwise direction of said yarn-drawing machine and being above the latter.
