Abstract
Abstract Apparatus for handling flexible elongate material such as textile yarn comprises feed rolls for feeding the material forwards, means for forming the material into folds, and for maintaining the folds for a determined period. The folds may be formed by successively displacing the yarn in opposite directions laterally of its line of travel. The yarn may be space printed in the folded condition.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
184 words
Apparatus for handling yarn comprising a plurality of surfaces, yarn feed means, a device spaced from said feed means adapted to receive both the yarn from said feed means and also a supply of fluid, and to direct the yarn and fluid towards said plurality of surfaces, and means for continuously moving said surfaces in a manner to define at least one yarn receiving zone, said device being spaced from said surfaces and disposed so as to direct the yarn and fluid into the zone, the arrangement being such that the yarn is folded subsequently to leaving said device, is located in the folded state in the zone, and is there so transported, wherein the surfaces comprise a yarn retarding surface and a support surface on which the yarn is received after contact with said retarding surface, and wherein there are a number of zones formed by vanes radiating from the surface of a rotary shaft or drum, the surface of the shaft or drum comprising said support surface, and an end closure member connecting the vanes at one end constituting said retarding surface.
Claim 2
Dependent Claim
184 words

Claim 3
Dependent Claim
24 words
Apparatus according to claim 1, including an enclosure member extending around at least part of said drum at the free ends of said vanes.
Claim 4
Dependent Claim
51 words
Apparatus according to claim 2, wherein said enclosure member comprisEs an endless conveyor belt which rotates the drum through contact with the free ends of said vanes and on to the lower run of which the contents of each zone are deposited in a single layer of folds for subsequent removel.
Claim 5
Dependent Claim
27 words
Apparatus according to claim 2, wherein said enclosure member is comprised of a series of caps one secured to the free end of each of said vanes.
Claim 6
Dependent Claim
24 words
Apparatus according to claim 4, wherein there are axially extending gaps between adjacent caps to permit of removal of yarn radially from said zones.
Claim 7
Dependent Claim
22 words
Apparatus according to claim 2, wherein said vanes are double-walled and converge to a point at the entrance end of each zone.
Claim 8
Dependent Claim
184 words
Apparatus for handling yarn comprising a plurality of surfaces, yarn feed means, a device spaced from said feed means adapted to receive both the yarn from said feed means and also a supply of fluid, and to direct the yarn and fluid towards said plurality of surfaces, and means for continuously moving said surfaces in a manner to define at least one yarn receiving zone, said device being spaced from said surfaces and disposed so as to direct the yarn and fluid into the zone, the arrangement being such that the yarn is folded subsequently to leaving said device, is located in the folded state in the zone, and is there so transported, wherein said surfaces are moved so that they first come together to define at least one zone and then move apart again, and wherein there is one zone formed by a wheel having a recessed channel between axially spaced rims, an enclosure member extending around part of said wheel and contacting the outer edges of said rims, the device being arranged to direct the yarn substantially tangentially on to said wheel.
Claim 9
Dependent Claim
184 words
Apparatus for handling yarn comprising a plurality of surfaces, yarn feed means, a device spaced from said feed means adapted to receive both the yarn from said feed means and also a supply of fluid, and to direct the yarn and fluid towards said plurality of surfaces, and means for continuously moving said surfaces in a manner to define at least one yarn receiving zone, said device being spaced from said surfaces and disposed so as to direct the yarn and fluid into the zone, the arrangement being such that the yarn is folded subsequently to leaving said device, is located in the folded state in the zone, and is there so transported, wherein said surfaces are moved so that they first come together to define at least one zone and then move apart again, and wherein there is one zone formed by a wheel having a recessed channel between axially spaced rims, an enclosure member extending around part of said wheel and contacting the outer edges of said rims, the device being arranged to direct the yarn substantially tangentially on to said wheel.
Claim 10
Dependent Claim
44 words
Apparatus according to claim 7, wherein said enclosure member comprises an endless conveyor belt which rotates said wheel through contact with said rims and on to the lower run of which the yarn is deposited from said wheel as a single layer of folds.
Claim 11
Dependent Claim
14 words
Apparatus according to claim 1, wherein said end closure member is a mesh structure.
Claim 12
Dependent Claim
15 words
Apparatus as claimed in claim 3, in which the conveyor belt is a mesh structure.
Claim 13
Dependent Claim
15 words
Apparatus as claimed in claim 8, in which the conveyor belt is a mesh structure.
Claim 14
Dependent Claim
90 words
Apparatus for handling elongated flexible material comprising means for continuously feeding said material forward, continuously movable means spaced from the feed means for positively and successively displacing said material laterally of its line of travel at discrete intervals of time so as to form a succession of loops, means for transporting the looped yarn for a determined period, and comprising a plurality of members spaced in succession around a closed curve, the members being arranged to engage in succession a continuous length of advancing flexible material to form successive loops.
Claim 15
Dependent Claim
90 words
Apparatus for handling elongated flexible material comprising means for continuously feeding said material forward, continuously movable means spaced from the feed means for positively and successively displacing said material laterally of its line of travel at discrete intervals of time so as to form a succession of loops, means for transporting the looped yarn for a determined period, and comprising a plurality of members spaced in succession around a closed curve, the members being arranged to engage in succession a continuous length of advancing flexible material to form successive loops.
