Application October 12, 1954, Serial No. 461,878

4 Claims. (Cl. 26-55) This invention relates to power driven means which is expressly designed and effectually adapted for use during the handling of tubular knitted fabrics and has reference in particular to spreading, flattening and propelling the same during the course of applying Weighting media, or while sizing, softening, bluing and otherwise processing and finishing the same. I

Stated otherwise, the invention has to do with an improved apparatus for feeding of tubular knitted fabric to the rolls in a Wringer structure or other well known handling machine, for finishing in the dry stage, for example, preparatory to folding and rolling, and which lends itself admirably well to uniform and precise spreading results and is therefore, aptly and satisfactorily usable in conjunction with striped cloth, so much so that the stripes run straight and parallel when the stretched tube of fabric leaves the rear portion of the spreader.

It is a matter of common knowledge to those conversant with textile equipment, especially stainless steel spreaders for tubular knitted fabric, that it is necessary to effectively handle fabric tubes ranging in Width from 6 inches to 48 inches. In this connection it is, of course, old in the art to utilize so-called driven-type spreaders, that is, spreaders which have idling rollers incorporated therein and with which power driven external-type rollers cooperate, portions of the fabric tube being pulled between the inside rollers on the spreader construction and the friction contacting exterior rollers. So far as has been learned from a survey of the prior art adaptations, the exterior rollers turn in a horizontal plane on vertical axes and drive the fabric tube along the lengthwise folds or so-called longitudinal edges.

An object of the instant invention is to cause the fabric tube to pass and travel between elongate power driven horizontally disposed rollers which latter contact and frictionally drive the top and bottom portions of the tube transversely across the lengthwise dimension of the tube and wherein the interiorly disposed idling rollers on the spreader device are likewise in a horizontal plane and turnable on horizontal axes.

Briefly summarized, a preferred embodiment of the invention reduced to its simplest form has to do with a machine embodying stationary end frames or equivalent supports between which the upper and lower rollers are mounted for rotation, being turnable in stationary bearings on said frames and the journals on the upper roller being so constructed and arranged that the upper roller may be moved toward and from the lower roller, allowing the two rollers. to be parted or spaced so that the bodily insertable and removable spreader device may be readily sandwiched and wedged between the two rollers, "or withdrawn whenever necessary or desired.

More specifically, novelty is predicated on the spreader device per se characterized by a U-shaped front spreader frame, rear spreader fingers, and coplanar adaptors or coupling and assembling members arranged in opposed spaced journals on the lower roller States Patent ice parallelism with the respective spreaders detachably connected thereto.

Then, too, novelty is predicated on the adoption and use of adapters or castings which provide satisfactory guides over which the tube is caused to travel, said adapters having their intermediate portions constructed to accommodate cooperating detachable end portions of an assembling and connecting rod, whereby the adapters, using a rod of a given length, may be utilized for tubular fabrics six inches in width, and also used with another rod for forty-eight inch width, and all other required rod lengths and widths between the two extremes.

Objects, features and advantages in addition to those specifically touched upon will become more readily apparent to the reader as he reviews the following detailed description and subjoined claims.

In the accompanying drawings, wherein like numerals are employed to designate like parts throughout the views:

Figure 1 is an elevational view of tubular fabric spreading and propelling means or so-called apparatus, constructedin accordance with the principles of thepresent invention, and showing the manner in which the same is used.

Figure 2 is a top plan view of the same.

Figure 3 is a perspective view of the assembled readyto-use insertable and removable roller-equipped spreader device.

Figure 4 is an enlarged fragmentary sectional view taken on the plane of the line 4-4 of Figure 3, looking in the direction of the arrows.

Figure 5 is a view at right angles and on the vertical line 5-5 of Figure 3, also looking in the direction of the arrows.

Figure 6 is an enlarged perspective view showing certain of the structural details and the manner in which they are constructed and separably joined with one another.

Figure 7 is a perspective view of the aforementioned adapter connecting an assembling rod.

Reference is had first to Figures 1 and 2 wherein the machine or apparatus is shown. The numerals 8-8 designate suitably constructed fixedly mounted relatively sta tionary end frames. There is a horizontally disposed lower roller 10 provided with suitable journals 12. which are rotatable in appropriate bearings provided therefor in the end frames 8-8. This roller is provided at one end with an appropriate motion transmitting gear 14 and a sprocket (see Fig. 2) denoted at 16 and serving to accommodate a sprocket chain 18 operated by an electric motor or other equivalent prime mover 20. The frames, rollers and power means may be of any suitable construction, to contact the underneath side of the traveling or propelled tubular fabric denoted generally by the numeral 22. The gear 14 serves to drive a complement-a1 gear 24 carried by the upper horizontally disposed fabric feeding roller 26. This has journals 28 at its ends mounted in appropriate bearings 30 on support arms 32 pivotally mounted at 340m the respective end frames. The idea here is to have the roller 26 movable toward and from the roller 10 so that the spreader device and fabric may be inserted and removed. Any sort of spring tensioning device (not shown) may be employed to maintain the two rollers 10 and 26 in proper operative relationship. So much for the machine part of the over-all apparatus.

With respect to the bodily insertable and removable knockdown spreader construction or device, this is best shown in Fig. 3. It has already been pointed out that the device is characterized essentially by a pair of duplicated elongated block-like coupling members or castings 36-35. These castings are identical in conthe idea being to provide a first or primary roller.

struction and the description for one will sulfice for both. It will be noticed in this connection that coupling members are essentially hollow and have spaced parallel side members 38-38 with rubber or equivalent idling rollers journaled in any suitable manner therebetween. The rollers are preferably readily applicable and removable as shown by way of the bolt means seen in Figure 5. I provide pairs of upper rollers 4--t0 which are horizontal and in spaced parallelism and pairs of duplicate lower rollers 42-42. These paired rollers are located forwardly and rearwardly of the arcuate notches which are perhaps best described as segmental recesses 44 and 46. The forward or leading end portion of each member is tapered to provide a nose-like guide 48 and the rear end is likewise tapered at 50 to provide a similar nose-like guide; for smooth and uninterrupted movement of the tubular fabric. There is a lengthwise socket to one side of the nose 48 which is denoted at There are spaced parallel longitudinal sockets 54 in the rear tapered end 50 and these serve to accommodate the telescoping ends of the limb portions 56 of the readily attachable and detachable rear spreader members which are here referred to as generally V-shaped spreader fingers Sit-58. The front spreader is a U-shaped frame and this is denoted by the numeral 60 and the bight portion 62 bridges the respective spaced adapters or coupling members and the limb portions 64 are fitted telescopically into the aforementioned sockets 52 whereby the spreader frame 69 is readily attachable and detachable in respect to the adaptors 3636. It will be understood that the front spreader frames 60 will range inside from six inches to forty-eight inches to accommodate the gamut of sizes required for use in the mill and trade.

In addition to having to use a multiplicity of readily applicable and removable U-frames 60, it is also necessary to utilize rigid one piece connecting rods 66 of different lengths so that the adapters 36-36 may be set and firmly joined together either in closely spaced parallelism or spread relatively wide apart, as varying conditions require, Each rod is preferably of tubular form and has bayonet slots or notches 68 at its respective ends. The notched ends fit through holes 70 (see Fig. and into sockets 72 in the side members 38--3t5 of the adapters where the notched ends are connectible releasably with a retainer or keeper pin 74, a permanent part of the adapter block. Thus, the rod 66 is slid into position or withdrawn and detached depending upon the size requirements of any given or particular spreading job.

It will be seen, therefore, that a multiplicity of conmeeting and assembling rods 66 are utilized depending on size requirements and. that the rod ends are rcleasably connected with the respective adapter blocks. The same adapter blocks are used, however, from sizes of six inches to forty-eight inches, as is evident. In other words, it is not necessary to use adapters of different sizes but only spreaders 60, Sit-58 and connecting rod 66. In any event, these adapters lend themselves for placement between the aforementioned upper and lower friction pulling or driving rollers and 26 as brought out in Figs. 1 and 2. The curvate or segmental shaped recesses 44 and 46 lend themselves to conformation and location between the segmental portions of the rollers ill and 26 in an obvious manner. Thus, the fabric tube is spread over the forward spreader frame 60 and is thus opened up and flattened out. The rear end portion is drawn over and envelops the adapters 36-36 and their upper and lower rollers 4tl4tl and 424?. whereby the latter rollers are on the interior of the fabric tube and the driving rollers Hi and 26 extend transversely across the exterior surfaces of both top and bottom portions of said fabric tube. The rear end portion of the fabric tube is, of course, held in properly spread condition by way of the V-shaped spreader fingers 58-58. One can open up the rollers it? and 26 by swinging the roller 26 out of the way and then inserting the spreader device of Figure 3. The rollers are again closed and the device is ready for operation.

It seems advisable. to stress the fact that the ndaptcrs are roller equipped for disposition on the interior of the fabric tube, that they are properly recessed for lodgment and wedge-like retention between the rollers 10 and 26. The fabric is thus pulled with great rapidity and uniform evenness between these interior and exterior contacting rollers. The adapters being separably connected by insertable and removable connecting and assembling rods 66 are unique. The readily attachable and detachable spreaders 6t and 5858 are also thought to be a feature and improvement of appreciable advantage.

Persons skilled in the art to which the invention relates are, of course, conversant with various kinds of spreaders, feeding and driving rollers and so on. Perhaps, therefore, it may not be necessary to dwell at greater length on what appears to bc a clcar-cut disclosure of the subject matter of the invention under advisement and the obvious appropriation and use brought out especially when considering Fig. 3 first and then in conjunction with the readyto-use apparatus in Figs. 1 and 2.

From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact. construction shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.
