UNITED STATES PATENT; OFFICE- THOMAS H. BYRON/OF ELIZABETHTON, AND RALPH H. CARTER, OF JOHNSON CITY, TENNESSEE, ASSIGNORS TO AMERICAN GLANZSTOFF CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF DELAWARE APPARATUS FOR FILAMENT TREATMENT Application filed March 14, 1982. Serial No. 598,866.

The present invention concerns a new method whereby filaments upon perforated spools may be dried from one side only.

In the manufacture of artificial filaments, for example, by the viscose process, the spool process is sometimes used. According to this method the filaments are extruded into an ordinary acidifying setting bath, passed from there in the wet state directly upon perforated spools, Wet-treated in the usual manner. This wettreatment comprises the ordinary desulfurization, bleaching, washing, deacidifying, etc. It has been found that when artificial filaments are used and wet-treated upon these perforated spools, and then dried, an uneven drying filaments takes place. This is caused by the fact that the 'inner layer of the filaments resting directly against a rigid spool bodily contacts thereagainst, forming a very tight tape. outer layer of filaments similarly contract against the inner layer, and the result is unevenness of shrinkage. With filaments thus unevenly shrunk the physical characteristics of the same are altered in succeeding lengths. That is, the denier of the filament appears'to change and the surface of the individual threads'appears to possess varying degrees of hardness, according to the tension to which various lengths have been subjected. All of this results in the production of a finished production which has uneven dyeing qualities. In an efiort to obviate the unevenness of the dyeing it has been suggested that the filaments be dried from one side only, re-wet and then re-dried from the same side. Between the first drying and the second drying, the filaments may be rewound and twisted if desired uponanother spool so that those filaments which were originally on the inner side of the cake Will later be upon the outer side. These steps have produced a filament which possesses a very even dyeing effect inasmuch as very even shrinkage results. In order that these filaments might be treated more expeditiously and advan tageously in the plants, the present apparatus as been devised.

and, while upon these spools The One object of the present invention is to provide a means whereby a plurality of spools of filaments may be simultaneously dried from one side only.

Another object of the present invention is to provide a means of the type set forth which is so constructed that the filaments are, at all times, held out of contact with the faces of a container which might tend to damage them.

Other objects will become apparent from a perusal of the following specification and a study of the accompanying drawing, in which:

Figure 1 discloses across sectional view of a series of spools in superimposed position within our new type container,

Figure 2 is a detail view in cross section of one of the sub-containers for holding the individual spool, and

Figure 3 is a top plan view of the container disclosed in Figure 2.

The filaments (1) arewound upon perforated spools (2) and these spools are placed within a holder (3). This holder (3) comprises an outer body portion (4) provided at its bottom with inturned edge portions (5). A pair of gaskets (6) and (7) are arran ed above and below the inturned portions The inturned portions and the gaskets (6) and (7 are arranged so that a circumferential space 8) is formed. From between these two gaskets a holder (9) for the filaments comprising a three-arm upstanding cylindrical framework, is provided. The spools slip about this inner container, as shown in Figure 2, and the filaments (1) are thus held away from contact of the side walls (4) of the container. The lower edge (2') of the spool contacts with the upper gasket (6) of the container, thus forming an air-tight connection. The upper end (2) of the spool is adapted to bepressed against the lower gasket (7) of the next container in the superimposed series. The filaments are wound upon the perforated spool so that they cover all of the perforations of the same, and by sealin the upper and lower edges of the spools witfi the circumferential gaskets (6) and (7), it

is seen that an air-tight seal is provided and the filaments upon the spools may thereupon be dried from one side only, inside. A shell (10) in the form of a cylinder with an open end (11) surrounded by a gasket (12) is provided in order that a series of spools may be treated at one time. The spools are placed within the open end container so that the open end of the individual spool containers faces the end (11) of the container (10). When a suflicient number of spools in their containers have been placed within the cylinder (10) the cylinders are placed in a drying position as shown at (13) and hot air or other drying media is introduced to the opening (14). (13) are positioning lugs acting to locate the cylinder over the opening (14), which should be as wide as possible in order to freely admit the passage of the air. This air passing up through the center 'of the spools has access only to the inner surface of the same and therefore dries the filaments 4 upon the spools from the inside only, the outrequired by the patent statutes,

side filaments remaining in a wet state until the latter portion of the drying operation.

WVhen the drying has been completed, the cylinder (10) still containing the spools may be lifted bodily and transported to the position of the next operation, where the spools may be removed from the container.

As will be seen from a study of the steps outlined above, our new process provides a means whereby a series of spools may be now treated in an advantageous manner in about the same length of time originally required if one spool were to be wrapped so that it would be dried from one side only.
