This invention relates to textile products. apparatus and methods.

-In U. S. Patent No. 2,344,537,4dated March 21, 1944, in the name of the present inventor, there is described an a cle of manufacture comprising a textile fllame t wound and stitched to form a web suitable-for varied uses in the textile art. In application Serial No. 575,232, led on January 30, 1945, now Patent No. 2,482,655, and Serial No. 640,350, filed on January 10, 1946, now Patent No. 2,551,098, there appears "W" *w* a disclosure of the winding of a filament or filaments temporarily upon a. mandrel and then manipulating the wound filament or filaments to define a product suitable for uses of the types contemplated by the patent above identified.

In accordance with the present invention it is proposed to provide apparatus, methods and.

products distinguishing from those of the aforesaid patent and applications, the product however being intended for analogous uses such as the manufacture of rugs of the type wherein the pile is adhesively secured to a`suitable backing. Among other applications of the product of this invention are tapes, braid, tapestries, portiers, bed covers, trimmings, draperies, purses and other ornamental and utilitarian fabrics.

The product of the present invention comprises a helically arranged filament having one or more additional filaments extending through the helix and adhesively joined thereto. Where a tape-like body is contemplated, the wound filament defining the helix may be arranged as a substantially fiat ,tube maintained in its substantially flat condition by the internal adhesively attached filaments. The internal filament or laments may be located lby means of suitable adhesive at the edges of the substantially fiat tube. and Where desired to thicken such a tube, one or more laments may be adhesively appli-ed externally of the tube along its upper and/or lower edges. In some cases, the helically arranged filament may comprise a relatively soft textile material such as worsted while the internal filament may be a relatively hard textile material such as Jute. Any one or more of the filaments employed may be applied singly or plurally in twisted, knitted, braided or other suitable condition, and for purposes of this application, all are referred to as filaments.

A preferred method of practicing this invention contemplates advancing one or more laments axially, winding another filament about it or them, with its adjacent convolutions in contact where desired, and adhesively joining adjacent surfaces of the filaments. Where the products are to be split ultimately, as in the manufacture of rugs, a plurality of filaments such as two, are preferably used as a. core about which the wound filament is arranged, the internal filaments being preferably in substantially parallel spaced relationship. In those cases requiring the application Aof external laments for spacing or ornamental purposes. such filaments are applied to the wound body by means of an adhesive, at the edges of the substantially flat ments have been shaped and assembled, pressure is preferably applied to achieve the desired adheslve bond.l A highly satisfactory application of natural or synthetic `rubber latex has been achieved by feeding the internal and any external filaments in such a way as to receive a coating of the adhesive prior to contact with the wound filament. The subsequent pressing by suitably grooved rolls, for example, serves also to feed the various filaments at the required rates.

Apparatus suitable for carrying out the present invention may comprise a mandrel provided with one or more guides for the internal filament or filaments, means for winding a. filament about the mandrel and the internal filament or filaments and means for introducing an adhesive between the one or more internal filaments and the wound filament. Where external filaments are applied, means for applying the desired number will be provided together with means for introducing an adhesive between such external lament or filaments and the wound filament. Means is also contemplated for pressing the various filaments into contact so that they will be effectively joined by the previously applied adhesive.

A more complete understanding of the invention will follow from a detailed description of the accompanying drawings wherein:

Fig. 1 is an elevation partially in section depicting a form of apparatus suitable for carrying out methods and manufacturing products contemplated by the present invention;

Fig. 2 is a section taken along line 2-2 of Fig. 1;

Fig. 9 is an elevation of the product shown in Fis. 8.

With reference to Figs. 1 to 3, a cage 20 is made up of

end flanges

22 and 24 interconnected by rods or bars 26 provided in a number suflicient to produce adequate strength and at the same time afford access to the interior of the cage. The left end of the cage as viewed in Fig. 1 is provided with a hub 28, shown as drilled and threaded to receive a set screw 30 for securing the cage to a hollow rotary shaft 32. This shaft 32 is journaled in suitable bearings 34 carried by a pedestal 36. Intermediate its bearings 34, the shaft 32 carries a worm 38 in mesh with a wheel 40 xed to a, shaft 42. Also fixed to the shaft 42 is a sprocket 44 whose Yteeth cooperate with the links of a chain 46 extending behind the cage. 20 to drive a sprocket 48 located at the right end of the cage.

The hub 28 and shaft 32 have been shown as drilled transversely at a slight inclination to provide a passage 50 and the flange 22 is drilled at its intersection with the upper rod 26 to define a passage for a purpose to be described. The left end ofthe shaft 32 projecting beyond the pedestal has fitted thereto a pulley 52 for receiving a belt 54 driven by a pulley 56 mounted on the shaft of an electric motor 58.

The right end of the cage 20 terminates in a tubular shaft 60 which is supported in an outer bearing 62 fitted in a. pedestal 64. The'inner bore of the tubular shaft 60 receives a bearing 66 in which is journaled a tubular extension 68 for supporting the right end of a cradle 10. The left end of the cradle is supported through a suitable bearing 12 upon the inner end of the shaft 32 which projects a suitable distance within the case.

By virtue of the arrangement of bearings supporting the cradle 10, it will not partake of the rotation of the cage 20 and accordingly, will A shafts 82 are received in bushings 84 provided in v the upper edges of the cradle. The cradle 10 supports a fountain 86 in which a roller 88 is suitably supported for rotation in a body of adhesive 80 so that when the filaments 18 advance over the fountain roller 66, they will receive an application 'of adhesive for joining them to the lament 92 which is wound around them.

The lament 92 is supplied from a source 84 located at the left end of the apparatus depicted in Fig. 1. The lament 92 is threaded through the shaft 32 from which it is deflected through the passage by means of a suitable tool, extending radially of the flange 22, through one of the rods or bars 26 which is made hollow for this s purpose, to the flange 24 where it is deflected inwardly radially by means of a suitable tool inserted through an opening 86 adjacent the point at which the hollow rod or bar 26 adjoins the flange 24. The hollow extension is likewise drilled longitudinally in order that the filament can be threaded through it by means of a suitable tool introduced through an opening 88 aligned with the drill opening through the hollow extension 60.

The sprocket 48 is suitably journaled in a pedestal |00 by means of a shaft |02 which carries in spaced relationship with respect to the sprocket a grooved roll |04 whose periphery is received between the anges |06 of a grooved roll |08 carried' by a shaft ||0 in the pedestal |00 by means of suitable bearings.

Peripheral grooves ||2 provided in the upper roll |04 serve as guides for filaments ||4 supplied from a source, not shown, between the roll |04- and an adhesive application roller l I6 supplied with adhesive ||8 from a fountain |20 by means of a fountain roller |22. Similarly, where outer filaments are to be applied to the lower surface of the wound body, they are fed into the grooves |24 of-the lower roll |08. Such laments |26 are drawn from a source not shown, and fed over an adhesive applying roller |26 fed by means of a fountain roll |30 with adhesive |32 provided in a fountain |34. Pressure adjustment |35 is provided for the rolls.

From the foregoing description of the apparatus, it will follow that when the various filaments are threaded in proper relationship with respect to the apparatus, when the motor 58 is energized it will drive the pulley 52 and rotate the cage 20-to wind the filament 92 from the source 94 about the mandrel 14 and the filaments 1B which are advanced longitudinally along the grooves or guides provided by the mandrel. Since the filaments 18 have adhesive material such as natural or synthetic rubber latex applied thereto, as the filament 92 is wound about them, the desired adherence will be effected by the pressure of the rolls |04 and |08 which may be adjustable in any suitable vmanner to accommodate varying thicknesses of mate ial. Where outer filaments ||4 are provide n the upper surface of the woimd body and/or filaments |26 Yon the lower surface of the wound body, these are likewise supplied with a similar adhesive material from their respective fountains and are similarly pressed between the rolls |06 and |08 to the wound body whereby the desired unitary reu lationship is achieved.

Three examples of products produced in accordance with the apparatus and method hereinbefore described are depicted in Figs. 4 to 9 inclusive of the drawings. In Figs. 4 and 5 the tape-like body comprises a. substantially at tube formed from the filament 92 wound about a pair of laments 18 extending through the helix adjacent the edges thereof.

In Figs. 6 and 7 a somewhat similar product is depicted, having in addition a pair of external filaments ||4 joined to the upper surface for ornamental or spacing purposes.

In Figs. 8 and 9, a pair of external filaments |26 have been added to the lower surface of the tubular body, likewise for ornamentation and/or spacing functions.

In these Figs. 4 to 9 inclusive, the adhesive for uniting the various filaments has been depicted generally by reference character |36.

As previously stated, the filament 92 may in some instances be relatively soft textile material such as worsted while the internal filament or filaments 18`may be relatively hard textile materials such as jute. Such a combina.- tion of materials tends to lend stiffness to the finished product during further operations to which it may be submitted as in the manufacture of rugs, yet the ultimate Dile of such a rug will be soft and relatively resilient. It should be understood however that the materials constitutingvthe filaments may vary widely depending upon the application to which the product is to be put.

Y the scope of the invention should not be limited to these examples beyond the scope of the appended claims.
