12 Claims. (Cl. 139--307) This invention comprises a novel and useful ribbon roller attachment for ribbon looms and more particularly relates to an attachment which may be applied to conventional ribbon looms in order to more compactly wind ribbons or other similar woven fabrics in side-by-side relation upon a beam.

The primary purpose of this invention is to provide an attachment and a method whereby ribbons, Webbing or narrow fabrics after being woven upon conventional ribbon or narrow fabric looms may be rolled up in any desired number in side-by-side relation upon a single beam or reel, thereby forming a firm, solid beam of ribbons.

A further important object of the invention is to provide a method and an attachment applicable to conventional ribbon looms whereby the number of operations of handling the ribbons or woven fabrics between the weaving of the same and the dyeing operation may be greatly reduced; and whereby a much longer length of ribbon may be efiiciently handled.

Yet another purpose of the invention is to provide a method and an attachment for conventional ribbon looms whereby a plurality of ribbons may be compactly wound in side-by-side relation upon a single beam, thereby enabling the beam and the ribbons wound thereon to be directly positioned in a vat for pad dyeing or the like with a considerable reduction in the number of separate steps and operations of handling the ribbon that have been heretofore required.

Yet another object of the invention is to provide an apparatus and method whereby a plurality of ribbons produced from a single ribbon loom may be simultaneously rolled upon a single beam with equal tension of the ribbons thereon, thereby enabling dyeing with even colors for all of the ribbons and enabling the operation of level dyeing to be more easily performed than with other methods involving variances in the tensions of th ribbons.

Yet another object ofthe invention is to provide an attachment of an interchangeable nature whereby the same loom may be adapted for winding a pluralityof different widths of ribbons in any selected number in side-by-side relation, under a constant tension and upon a same beam.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had'to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which: T

Figure 9 is a fragmentary elevational view of a portion of the embodiment of Figure 8; and,

Figure 10 is a diagrammatic view, taken upon an enlarged scale, of a portion of Figure 2 and showing an important feature and principle of the invention.

Referring first to Figure 1 of the drawings, it will be seen that there is disclosed a conventional type of loom such as the well known Fletcher ribbon loom, the same including a frame 10 supporting the breast beam 12, the batten 14 with the shuttles 16. Indicated at 18 is the warp beam by which the warp threads are dispensed in two sets of warp threads 20 and 22, each passing under the back bars 24 and 26 to the harnesses 28 and 30 whereby for convenience and compactness they are fed into the upper and lower sheds of the loom.

The two sets of warp threads pass over the glass bars.

32 and 34, then overthe sand roll 36 and about the pressure roll 38, from thence over the ribbon guide rod 40 to the ribbon beam 42 which is driven by the friction drum 44 from the sand roll 36 through a chain and sprocket drive 46.

The present invention relates to an attachment which is operatively interposed between the glass bars 32, 34- and the sand roll 36; and to improvements in the friction drive of the ribbon beam 42 from the friction drum 44.

It will be understood that the warp threads are woven into narrow fabrics such as ribbons, Webbing, or other narrow fabrics between the batten 14 and the glass bars 32, 34. From the glass bars the ribbon passes through the attachment forming the principal subject matter of this invention to the sand roll 36, and thereafter is wound upon the ribbon beam 42.

Referring next to Figure 1, it will be seen that the ribbon beam 42 is provided with trunnions 48 which are journaled in notches 50 provided in the upper ends of the levers 52. The latter, in turn, are pivoted, as at 54, to support brackets 56 suitably secured upon the floor upon which the loom rests. Tension springs 58 are connected to the members 52 and to standard 60 to thereby yieldingly urge the spindle of the ribbon beam 42 against an appropriate friction surface of the friction drum 44.

The latter is preferably driven at a very slightly greater surface speed than that of the sand roll 36, by the sprocket chain drive 46, in order to apply a slight tension to the ribbons, as the same are wound upon the ribbon beam 42 by the frictional engagement of the drum 44 upon the surface of the ribbons wound upon the spindle of the drum 42. 1

It will be observed that the friction drum 44 thus serves to maintain an even tension for all of the ribbons wound in side-by-side relation upon the ribbon beam 42, in the position shown in Figure 3. As shown in this figure, the series of ribbons 62 are wound in close sideby-side relation thus permitting even and uniform winding of the ribbons in a compact manner, and at a uniform wound upon a single warp beam in each of the side by side rolls of ribbons.

It should be noted that by this arrangement the cus tomary loose coiling of the ribbon in boxes, as in prior conventional practice, which necessitates the subsequent winding of the ribbons upon spools or reels, as Well as a much greater provision of floor space for receiving the ribbons after they pass over the driving roller 44, is obviated.

It should be here noted that the warp beams will be of sufficient length to accommodate any desired number of ribbons to be wound side-by-side upon the same, and in order to accommodate different sizes of ribbons, as desired.

Referring next primarily to Figures 2, 5-7, it will be seen that there is provided a transversely extending plate 70 provided at its upper end with horizontally extending mounting brackets 72 whereby the plate may be mounted upon the breast beam 12 of the loom in a suitable manner, and below the glass bars 32, 34. At evenly spaced intervals longitudinally of the plate 70 there are provided a plurality of guide pins 74 projecting laterally from the plate. These pins are disposed at appropriate intervals corresponding to the ribbon 62 passing over the glass bars 32, 34. It will be noted, however, that a somewhat greater space is provided between the two central pins 76 and 78, which permit the central ribbon of a set of ribbons which are to be wound upon the same warp beam, such as the ribbon 62a, see Fig. 2, to pass between these guide pins.

Depending from the central portion of the plate 70 are a pair of arms 80 and 82 which support in dependent relation a guide plate84 which may be integrally connected with the arms 80, 82, or may be detachably secured thereto, as set forth hereinafter. The plate 84 is provided with a plurality of longitudinally spaced laterally extending ribbon guide pins 86, the spacing between which is in accordance with the length of the particular width of ribbon which is being produced upon the loom. As will be now readily apparent, the number of the guide pins 86 will correspond with the number of the guide pins 74, and the two central guide pins 88 and 90 are spaced apart a distance suflicient to permit the passage of the central ribbon 62a previously referred to therebetween, and also the two adjacent ribbons as will be apparent from Figure 2.

While the spacing between and the actual position of the guide pins 74 are relatively unimportant and subject to wide variation, the actual positioning and spacing of the pins 86 is extremely important. As will be apparent from the diagrammatic view of Fig. 5, any particular ribbon 62 which passes over the glass bars 32 or 34 has the plane ofitssurface tangent to the glass bar 34. How ever, as will be apparent from Figure 10, the ribbon 62 or 62a, as the same pass over the glass bars 32 or 34, travel with their surfaces tangent to that of the glass bars. The ribbons, however, are then turned through 90 degrees in order that their surface may be now tangent to the guide pins 74 as the ribbons travel from thence towards the second set of guide pins 86. It will be observed that the vertical medial plane through the ribbons 6201' 62a, as indicated by the line 92 in Figure 10, is tangent to the surface of the pins 74 about which the ribbon turns, in order that the tension may be along the center line of the ribbon. t V

In a similar manner, as will be apparent from Fig. 2,

.the ribbons after passing about the second set of guide pins 86, are again rotated through 90 degrees and then pass in close parallel side-by-side relation from the last set of guide pins onto the sand roller 36. It will therefore be observed that when the present attachment is applied to a ribbon loom, the Weaving of the ribbons is exactly in accordance with previous practice, and the woven ribbons then pass from the glass bars and to the first set of guide pins of the attachment in exactly the same relationship as in conventional looms. However, at this point the ribbons are brought more closely together so that the selected number of ribbons to be wound upon a single ribbon beam will be in close side-by-side juxtaposition, and yet wherein there will be no tendency to pull a ribbon on a bias or other than along its medial line.

It will now be understood that the guide attachment assembly consisting of the plates 70 and 84 will be each arranged with its corresponding guide pins in an appropriate position to take different sizes of ribbons; and also to take a different number of ribbons and dispose them in side-by-side relation. When it is desired to change either the number of the ribbons to be wound upon the warp beam or the width of the ribbons, it will be necessary to replace the attachment with another having the appropriate spacing and number of the guide pins thereon.

It is possible, however, to provide a further guide attachment which may be more readily adapted for use with different sizes and Widths of ribbons. For that purpose, the arrangement shown in Figures 8 and 9 may be employed. In this arrangement, there is provided an upper guide plate 94 having the horizontal mounting brackets 96 thereon, together with the first set of guide pins 98, corresponding to the respective members 79, 72 and 74 of the preceding embodiment. However, in place of the arms and 82, there are provided depending arms 100 which are welded or otherwise secured to the back side of the plate 94, and which at their lower ends have detachably secured thereto as by fastening bolts 16?. the upstanding arms 104 of a replacement lower plate 106 having thereon the second set of guide pins 108. The plate 106 of pins 108 will, of course, correspond to the plate 84 and pins 86 of the preceding embodiment. in this latter form it is therefore evident that the second set of guide pins may be readily replaced with a plate having a different spacing of pins thereon in order to permit the weaving of ribbons of different widths.

Referring now to Figures 3 and 4, it will be seen that an increase in the length of the ribbon beam, for receiving wider and/or a greater number of ribbons thereon will necessitate a variation in the length of the friction drum 44 in order to uniformly apply tension to the surfaces of the rolls of ribbons. For this purpose, either or both ends of the drum 44 are provided with a series of interchangeable extension sleeves 45 detachably secured by means of suitable bolts to the brackets 47. If desired, the brackets could be carried by the extension sleeves.

The foregoing is considered as illustrative only of the principles of the invention. Further, 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 and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

1. A method of gathering and winding ribbons in close side-by-side relation upon the ribbon beam of a ribbon loorn of the type having a glass bar which comprises: moving the ribbons in parallel paths as they leave the glass bar and rotating them perpendicularly about their longitudinal axes, moving the ribbons into a relatively close juxtaposition and parallel relation, thereafter rotating the ribbons back into their original attitude.
