C., assignor to Carolina Rubber Hose Company, Salisbury, N. C., a corporation of North Carolina Application April 18, 1955, Serial No. 501,828

4 Claims. (Cl. 203-355 This invention relates to dye beck machines and more particularly to an improved reel for such machines.

Dye beck reels have heretofore been equipped with a plurality of spaced parallel metallic bars extending between opposed heads of the reel and about which ropes of fabric are looped whereby the fabric can be passed through the dye liquor. These metallic bars have sometimes been formed in the configuration of elongated cylindrical rods and this has proved disadvantageous in that the cloth has a tendency to slip on the smooth cylindrical rods, thereby permitting the reels to rotate relative to the cloth.

Attempts have been made to overcome this difficulty by forming the metallic bars in the configuration of elongated L-shaped members, such as angle irons, but this has proved disadvantageous in that the cloth is subject to bruising and chafing in passing over the sharp corners of the L-shaped metallic bars. Such bruising and damaging of the cloth can be eliminated by first wrapping the L- shaped bars with cloth other than the fabric which is to be dyed in the dye beck machine. However, this has also proven disadvantageous in that upon changing the liquor in the dye beck machine, the cloth with which the individual metallic bars are wrapped has to be changed also to prevent a foreign color from being imparted to fabric being treated.

It is an object of this invention to overcome this and other disadvantages heretofore encountered in the use of metallic bars in dye beck reels by providing an improved dye beck reel which may be easily cleaned and which will not permit slippage of the ropes of fabric nor will it bruise or otherwise damage the fabric as it is passed thereover during the dyeing process.

It is more specifically an object of this invention to provide a reel for dye beck machines comprising opposed heads connected by a plurality of elongated cylindrical members, each of which is provided with a covering having a flexible irregular surface for engaging the fabric as it passes over the reel to prevent rotation of the reel relative to the fabric and at the same time to insure that the cloth will not be damaged.

It is another object of this invention to provide a dye beck reel comprising a plurality of fluted rubber covered rolls extending between opposed heads of the reel wherein means are provided for normally preventing rotational movement between the rolls and the heads, said means also permitting the individual rolls to be rotated one-quarter revolution relative to the heads to present a new roll surface to engage the fabric upon a previously exposed rol-l surface becoming worn. Means are also provided whereby the rolls may be readily removed from the heads when desired.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which- Figure l is a somewhat schematic transverse sectional 7 ing rectangular hubs or lugs 43.

Referring more specifically to the drawings, the numeral 10 broadly indicates a dye beck machine having a housing 11 supported on a base 12, which housing 11 may include a housing top 13 and [front and rear vertically sliding doors 14 and 15, respectively, mounted in vertical guides 16. A tub or receptacle 18 is disposed within the housing 11 for the reception of dye liquor L and a reel 20 and a front roll 21 are suitably journ'alled in the sides of housing 11 above the tub 18. A doifer roll 22 is suitably journalled in a pair of forwardly extending arms 23, only one of which is shown.

The reel 20 is keyed on a shaft 26 as at 27, and opposite ends of the shaft 26 preferably extend through corresponding sides of the housing 11 and are suitably journalled in bearings 30 and 30 mounted on respective brackets 31 and 31' secured to the housing 11. Means, not shown, are provided for imparting rotation to the shaft 26 relative to the housing 11.

The foregoing structure is illustrative only and merely serves to identify an environmental embodiment with which my invention may be associated, it being understood that the invention may be readily associated with various types of fabric treating machines without departing from the spirit of the invention.

The improved'reel 20 comprises a pair of spaced cylindrical heads 32 and 33 which are preferably formed from stainless steel and provided with outwardly extending annular flanges 34 for reinforcing and obtaining rigid head 32 and 33. The central portion of each of the head 32 and 33 is provided with a hub 35 keyed on the shaft 26 and a bearing plate 36 is secured to the outer surface of each of the heads 32 and 33 opposite the hub 35. The bearing plates 36 are also penetrated by the shaft 26 and each serves as a bearing surface for nuts 37 threaded on the shaft 26 to normally prevent endwise movement of the heads 32, 33 relative to the shaft 26.

A plurality of spaced rolls 40 extend between the heads 32 and 33 and although there are six such rolls indicated in Figures 1, 2 and 3, it is to be understood that any desired number of rolls may be used. The rolls 40 are preferably arranged in an elliptical pattern between the heads 32, 33, and each of the rolls 40 comprises a hollow steel cylinder 41 closed at both ends by end walls 42 from the outer surface of which project axially extend- The lugs 43 extend through correspondingly shaped openings 43a (Figure 6) in the heads 32 and 33 as seen in the lefthand side of Figure 2 thereby normally fixing the rolls 40 against rotational movement relative to the heads 32 and 33.

The rolls 40 also include a non-absorbent resilient or rubber cover-ing 44 suitably bonded to the outer surface of the metal cylinder 41 and extending about the outer surface of the end walls 42 in abutting engagement with the rectangular lugs 43.

The outer surface of the resilient or rubber covering 44 is fluted. The fluted surface is formed by spaced axially extending projections 45, which preferably exthe tend the entire length of the rolls 4%). The projections 45' do not extend radially adjacent the end walls 42 that portion of the rubber covering 44 being preferably provided with a smooth outer surface. I

The spacing of the projections may vary in accordance with the diameter of the roll 46, but it is preferable that the projections 45 be spaced a sufficient distance and be of such a width as to permit the same to flex or bend under the weight of fabric F carried by the reel 20.

The bending of the projections 45 under the weight of the fabric F increases the frictional contact between the rolls 40 and the fabric F and at the same time presents a sharp yieldable surface which digs into the fabric and has been found to greatly reduce slippage of the fabric on the reel 20 without bruising or chafing the fabric. This is an important feature of the invention since it permits large quantities of fabric to be uniformly dyed.

It will be noted that the head 32 is preferably spaced inwardly from the housing 11 a sufficient distance to permit the corresponding nut 37 to be loosened whereby the head 32 may be moved to the left in Figure 2 to disengage the head 32 from the lugs 43 on the rolls 40. In this manner, the rolls 40 may be periodically rotated a quarter of a turn relative to the heads 32 and 33 to present a new Wearing surface to the fabric upon a previously exposed wearing surface becoming worn. The rolls 40 may also be completely replaced, if desired, in a similar manner.

It is to be understood that the projections 45 may be arranged in sinuous paths instead of in straight paths as shown in the drawings. Also, if desired, the projections 45 may be divided into sections longitudinally thereof.

It should be noted that a hard rubber core may be used in lieu of the metallic cylinder 41 if desired, but in any event, it is apparent, that the rolls 40 may be easily cleaned when it is desired to change the dye liquor in the tub or receptacle 1%. The overlapping end portions of the resilient or rubber covering 44 which tightly abut against the lugs 43 permit the rolls to be easily cleaned when it is desired to change the dye liquor in the tub 18.

It is thus seen that there is provided an improved reel for dye beck machines which greatly facilitates the handling of fabric within the machine.

In the drawings and specifications there has been set forth a preferred embodiment of the invention and although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being defined in the claims.
