lniGreat Britain March 2'l,* 1942 This invention relates to areel for use in treating artificial-filaments, threads, fibres and the like, hereinafter referred to as threads, and
is particularly adapted for treating a thread with.
ainumber of different liquids in succession, while the thread is 1' carried by and isetravellingalong athread-advancing device; a w v It has already beeniproposed to producers. thread by extruding a thread-forming solution such asvisco'se into a coagulating bath and'then to pass the thread as it leaves the coagulating bath into. contact, witha succession of different: treating liquids, such for instance as washing, desulphiding, bleaching, and final'washing liquids, and then to dry the thread, sothat it is, in
one continuousoperation, produced as the fin.
ished thread, ready to be employed for textile purposes. a It has been proposed to carry out the treatment of the thread withythe different liq-.-; uids on a succession of rollers, one roller or set of rollers being employed foreach operation, and each roller or set of rollers dipping into, or being sprayed with the required liquid.
It has also been proposed to pass the thread leaving the coagulating bath on to a device or series of devices adapted to advance the thread in a large number of helical turns. Such devices may consist of a pair of rollers with inclined axes, or of one roller and a series of guide hooks, or of a single reel comprising two sets of interdigitating bar members. When the thread travelling along the thread-advancing device is treated with a succession of difierent liquids, such as those enumerated above, large quantities of the treating liquids are required as only a single thread or at the most a small bundle of. threads,
is treated on each device. In order to carry out the process economically it is necessary to provide means for recovering the used liquids, and circulating them for reuse. When the treatment with each liquid is carried out on a separate device, this is comparatively simple, but when the thread is treated with several different i liquids on one device, the liquids are liable to-intermix and become unsuitable for'further use in that particular zone of treatment,
It has further been proposed to treat thread travelling on a thread-advancing reel with a succession of different liquids and to collect the liquids separately by providing suitable means which allow the liquids to drop off into separate collecting compartments. For example, the bars of the reel may be provided with ribs on the outer face of the bar so that liquid running down the holes may be provided on the "outer face of the' bars; or; an air jet may be employed. g I have'now found'that I can treat'a travelling thread with a succession of different liquids and 5 collect the liquidsseparately' -by=using a reel consisting 'of a plurality of longitudinal bar-members flttinginto slotsin a number of spaced solid discs mounted on a shaft, said barmembers being grooved" along most'of their lengthexceptm at those pointswhere the bar members fit into theslotsin the solid discs;
The thread may be made to travel along the reel his large number of advancing helical turns by any of the well known methods. For example, two reels may *beused with their axes inclined at a slightangle, or one reel may be'used" inconiunction with a seriesoi. guide hooks, or
a' single reel may be used comprising two sets of interdigitating barv members with a slight: Q modification of the discs supporting the bar members, to allow for the reciprocating movement of the bars.
The solid discs are preferably flat and circular and are provided round their circumference with 25 a plurality of slots which may be tapered and are ly liquid impervious. barrier, so that the reel is divided into a number of zones and-a different treating liquid may be applied ty sprinkling to each zone, the liquids remain separate and can be collected in suitable devices placed beneath each zone. The length of each zone is defined by the length between two successive discs. In
the treatment of a freshly spun viscose thread, for example, a reel may be used made from lonaigitudinal bar members according to the present 60 phiding liquor in the second, followed by water in the third, a bleaching solution in the fourth, and a final washingwater in the fifth zone. In this way the thread is washed, desulphided and bleached in a continuous operation. The washbar is caused to drop oil on reaching the ribs; or ll s liq i d s phidins liq and bleaching 0- lution are recovered and circulated in any desired and suitable manner,
The drawing accompanying this specification, will assist in illustrating the nature of this invention, but the invention is not restricted to the 'method and apparatus shown in the drawing.
The drawing shows-- In Figurel an elevation of a reel according to this invention;
In Figure 2 an end view of the reel of Figure 1.
- 11; Figures 3 and 4 sections of the bar member at different points and In Figure 5 a perspective view of'part of a bar member and part of a disc. 7 The reel consists of a shaft A,.capable .oi' being rotated by means not shown, on which, are mounteda number of circular discs B provided with hubs C by which they are keyed to the shaft A in any convenient manner.
The discs. B are provided with a number of peripheral slots D for the reception of longitudinal bar members E.
Between the discsB the bar members am provided with a groove in their outer surface, but the portions ofthe bar members E immedi-j ately adjacent the periphery of the discs B are not grooved. This is clearly shown in Figure 5.
Thus at any point between the. discs B, the ,bar'
members E have a cross section as shown in Fig-" ure 3,- whereas immediately adjacent the discs B the bar-members have a cross section as shown in Figure '4.
If a thread is caused to travel in ahelix along thereel shown inFigure 1 it may be subjected totreatment with two different liquids by .ar-
ranging suitable spraying means above the reel to'the left and the-right of themiddlerdisc B, and the treatment liquids may be collected separately byarranging troughs beneath the reel 7 It is thus possible to collect the treatment liquids separately without any substantial mixing with adjacent treatment liquids.
'The bar members E are of such a thickness that they project slightly beyond the periphery v of the discsB as may be seen from Figures 2 and 5.v It is therefore impossible for the thread to foul the periphery of the discs B as it moves along the bar members E.
What I claim is: 1.7 A, reel suitable for treating a travelling thread with a succession of different liquids and collecting the liquids separately comprising a shaft, a plurality of solid discs mounted in spaced relationship on said shaft, a plurality of peripheral slots in each of said discs a plurality of iongitudinal bar-members fitting in saidslots and adapted to support the travelling thread, the portions of said bar-members between each two successive discs constituting a zone of liquid treatment, andlongitudinal grooves in said bar-members,said grooves not extending beyond the ends of said zones of liquid treatment whereby treatmerit. liquid :in said grooves is prevented from passing from one zone of liquid treatment to next.
2. A reel according to claim solid discs are circular.
