'1 Claims.

This invention relates to apparatus for handling filamentary material. More particularly,

' vthe invention relates to apparatus for applying liquid to artificial filamentary material.

In the manufacture of artificial filamentary material in accordance with the viscose process, for example, where the spinning solution is extruded into a suitable coagulating medium, it

i is conventional practice to withdraw the thread from the bath and pass it around a pair of spaced apart rotating godets the first of which is. partially immersed in a treating liquid. For obvious reasons of economy and space-saving it is preferred that the vessel containing the treating bath be as narrow as possible. However, when such narrow treating baths are utilized in conjunction with heretofore known godets, it is extremely difficult for the operator to lace-up the godet by hand alone, and this difllculty is greatly aggravated in those cases where the treating liquid is maintained ata high temperature, r is such that it has a corrosive action, since it is possible for the operator to put his hand in the bath without suffering untoward eifect.

The aforesaid difllculties are all avoided by the present invention which provides a, novel godet,

one face oLwhich is open, andwhich has at least one notch in the peripheral rim about the open face.

In the drawing: t

Figure 1 illustrates, diagrammatically, an arrangement including a godet according to" the invention;

Figure 2 is a pl'anview of part of Figurel showing' the lacing-up operation;

Figure 3 is another view of the lacing-up operation: and

Figure 4 is a plan view of a further embodiment of the invention.

Referring to the drawing, the layout of Figure 1 comprises a setting bath 2 contained in tank j into which the spinning solution is extruded ment between the thread and godet is obtained through submerged Jet-l. The thread 5 thus formed is led upwardly ,under a thread guide 6 and around roller 1, which isrotating in the direction of the arrow. Godetl supported on spindle I which is driven by suitable means (not shown) is mounted cent the spinning bath, and is partially immersed in a treating liquid II contained in vessel ii.-

The bath may be bot'wate'r, dilute acid, or any other appropriate treating liquid. In lacing-up, as shown moreclearly in Figure 2, the leading end of thread 2 is drawn across the open face of godet and held in contact with the peripheral so that its open face is adjaand before being lapped about godet l5 one or contained in narrow vessels, especially when the of trayel of the material when the godet is rolaterally thereof. After such lapping, the thread may proceed directly to godet or it maybe wrapped once more about the guide It preparatory to displacement of an additional lap about g'odet 8. Any number of laps upon the godet may laterally displaced on the periphery of the godet in such a manner that a non-slipping engageand to prevent the thread from riding upon itself on the periphery of the godet. A'guide i6 is disposed adjacent godet it, about which thread 5 is wrapped, after passing around godet' I! once,

more additional times. From godet 15 the thread is passed to a suitable collecting device (not shown).

If desired godet I! may be rotated at a higher peripheral speed than godet 8, so that the thread passing therebetween is stretched to any desired or permissible extent.

The godet of my invention has the advantages that it may be laced-up by hand alone in a facile manner and with a minimum expenditure of time and eifort regardless of the conditions under which it is employed. It is particularly valuable for use in connection with liquid treating baths liquid is such that it is dangerous for the operator to permit his hands to come in contact with it.

Once the godet has been laced .up the thread passes uninterruptedly thereabout and the notches in the peripheral rim surrounding the open face thereof do not interfere with free, smooth and continuous travel of the thread from the setting bath to the periphery of the godet.

The notches I! which are spaced about peripheral rim II of godet 8 may be so disposed therein that they comprise at least one surface which inclines steeply from the rim and opposes the direction of travel of the filamentary material when the godet is rotated in the direction indicated by the arrow, in the drawlng or the notches may be disposed in the rim so that they comprise at least one surface which inclines steeply from the rim and opposes the direction tated in a direction reverse to that shown in Figures 1 to 3, inclusive. Alternatively, as shown in Figure t the notch I! may be bi-directional and may comprise two surfaces which incline steeply from the rim l2 and one of which opposes-the direction of travel of the material regardless of the direction of rotation of godet 8 so that the same godet may be rotated in either a clockwise or counterclockwise direction and effectively laced up in either case.

The godet may be formed of any suitable material such as glass,-hard rubber,- pyrosylin, Bakelite, etc. The-periphery of the godet may be smooth or corrugated, and the notches which are provided in the peripheral rim surrounding the open face thereof in accordance with the invention may be cut or molded therein.

The above description is intended to be illustrative only and it is to be understood that changes and variations may be made without departing from the spirit and scope of the invention as defined by the appended claims.

-, I claim:

1. A rotatable godet for use in handling filamentary material, said godet having a supporting means, an open face away from the supportrim being free of projections, means for rotating the godet, and a draws-off device for continually withdrawing the liquid-treated filamentary material from the godet.

.5. Means for applying liquid to filamentary material comprising a container for the liquid,

a godet partiallyimmersed in the liquid, said said notch comprising at least one surface which ing means, and at least one notch in the peripheral rim surrounding the open face, the rim being free of projections.

. 2. A rotatable godet for use in handling filamentary material, said godet having a supporting shaft, an open face away from the shaft and at least one notch in the peripheral rim surrounding the open face comprising at least one surface which inclines steeply from said rim, therim being free of projections.

,3. A rotatable godet for use in handling filamentary material, said godet having a supporting shaft, an open face away from the shaft, and a plurality of spaced notches in the peripheral rim surrounding the open face each comprising at least one surface which inclines steeply from said rim, the rim being free of projections.

inclines steeply from the rim, the rim being free of projections, a guide means positionedadjacent the godet and adapted to remove the filamental-y material from the godet and replace it thereon in a manner to effect lateral displacement of the material on the periphery of the godet, means for rotating the godet, and a drawofl device for continually withdrawing the liquidtreated filamentary material from the godet.

6. Means for applying liquid to filamentary material comprising a container for the liquid, a godet partially immersed in the liquid, said godet having a supporting means, an open face away from the supporting means, and at least one notch in the peripheral rim surrounding the open face which notch comprises at least one surface" which inclines steeply from the 'rim, the rim being'free of projections, a guide means positioned adjacent the godet and adapted to remove the filamentary material'from the godet and replace it thereon in a manner to eifect lateral displacement of the material on the godet, means for rotating the godet, a. second godet for continually withdrawin the liquid-treated filamentary material from the first godet, and means for rotatingthe second godet at a higher peripheral speed than the first godet to eil'ect stretching of the liquid-treated filamentary material free of projections.
