8 Claims.

The present invention relates to an improved form of thread processing apparatus. More particularly, the invention pertains to a novel means for use in the manufacture of doubled and twisted thread, yarn, cord, and the like, hereinafter referred to generally as cord."

One of the important objects of the present invention is to provide an improved form of device which is adapted to be applied to conventional doubler-twister apparatus for introducing a definite predetermined tension on the composite cord formed by the doubling and twisting operation in the course of which a plurality of individual threads of natural or synthetic origin are Joined to form a cord and then twisted together.

It is a further object of the present invention to provide a mechanism which will enable the production of an improved cord characterized by a more uniform twist and gauge.

, It is a still further object of the present invention to provide an apparatus which is capable oi? manufacturing a finished cord on which all of the loose and projecting fibers of the several component threads are laid in substantially parallel alignment, thereby producing a composite cord having a smooth finish.

It is another and still further object or the present invention to afford a means capable of operable association with a conventional doublertwiste'r apparatus which will apply heat for the drying and burnishing of a chemically treated composited cord.

Other objects and advantages of the present invention will become apparent as the following detailed description of one form of installation illustrated in the accompanying drawings and embodying the principles of the present invention proceeds.

The device of the invention is particularly advantageously adapted to be employed in combination with conventional forms of doubling and twisting apparatus. Such apparatus is capable of handling a large number of individual thread supply packages, each of which supplies a single thread, and for joining with other similar threads from adjacent series of supply packages to form a composite cord. Conventional doubler-twister apparatus embodies a plurality of cord-forming units arranged in spaced generally parallel relation extending longitudinally of the machine as a. whole.

Figure 1 represents a partial end elevation of a typical form oi doubler-twister apparatus with which the teachings of the present invention are particularly advantageously adapted to be embroken away. Figure 3 pioyed. Figure 2 is an enlarged front elevation of the apparatus of the invention with parts is an elevation of the apparatus of Figure 2 as seen from the line 3-4 therein. Figure 4 is a sectional view taken along the line 4-4 in Figure 2. Figure 5 represents a fragmentary front elevation of the apparatus of the invention corresponding generally to Figure 2.

In Figure 1 of the drawingathe reference numeral I designates generally a doubler-twister apparatus to which the cord processing device of the invention has been applied. The doubler-twister apparatus 4 is provided with a frame 2 on whichs mounted a spindle support 3 which'carries a plurality of spindles 4 and guides 5 disposed in spaced, parallel relation in a substantially horizontal plane.

Each of the spindles 4 carries a supply spool 6 for providing a thread end i to be incorporated into a composite cord in the course of the operation of the doubler-twister apparatus. The several threads through a gathering guide it which serves to ar range them in generally parallel relation to form,

the cord 9. The cord 9 next passes over and in contact with the surface of a dip roll it supported by a longitudinally extending freely rotatably mounted shaft ii. The dip roll it is disposed in a supply of processing liquor contained in a trough it which is supported from the frame 2 by a supporting bracket i3.

After leaving the dip roll ill, the composite cord 9 is directed about the under side or a positively driven roll i l, around an idler roll 18, and under a second driven roll 15. This arrangement of the positively driven rolls I 4 and ii in combination with the. idler roll i6 insures apositive, uniform feed of the cord to the subsequent twisting operation. The cord 9 next passes over a driven burnishing roll H, the function of which will be explained in greater detail hereinafter, to a guide eye I! which directs the cord to a traveler I! mounted upon a ring 20 on the ring rail 2i and finally to the collecting spool 22.

The build-up of the package of cord 9 on the collecting spool 22 is achieved in a conventional manner by the" reciprocation of the ring rail 2| in combination with theaction of the traveler I9 as it traverses a circular path about the ring 20.-

The collecting spool 22 is simultaneously driven at a high speed of rotation by a pulley 23 which is actuated by a belt or dip drive 24. The collecting spool 22 is disengageably attached to the pulley 23 which is in turn mounted upon a stub shaft 25 1 pass from the supply spools i 3 disposed in a bearing support 29. The fixed rail 21 carries a plurality of the stub shafts 25 and bearing supports 29 disposed in spaced relation along the longitudinal dimension of the machine. The fixed rail 21 is supported from the frame 2 of the machine as by means of a frame mounting bracket 28.

The cord p ocessing apparatus of the present invention, as more clearly illustrated in Figures- 2 to 4, inclusive, of the drawings, serves to provide a compressing and burnishing effect upon the cord 9 as it passes over the burnishing roll H in its path of travel from the driven rolls l4 and I! of the twister feed mechanism to the collecting spool 22. The

shafts

29 and 39, upon which are mounted the driven rolls l4 and I5, respectively, are supported at one end thereof by a suitable bearing bracket 3| mounted upon the frame 2 of the doubler-twister apparatus i and at the other end thereof in bearings 32 on an end plate 33 forming part of the frame 2.

The ends of the

shafts

29 and 39 extend slightly beyond the end plate 33, thereby enabling the shaft 29 to carry a sprocket 34 and chain of a driving mechanism which is actuated by the prime mover (not shown) of the doubler-twister appa- V ratus i. A spur gear 36, secured to the shaft 29, transmits power to a spur gear 31 mounted upon the end of the shaft 39 through an idler gear 33 freely rotatably mounted upon a stud 39 secured to the end plate 33. V

' A suitable housing 49- may be employed to enclose all of the driving apparatus at the one end of the doubler-twister apparatus i and disposed beyond the end plate 33 of the frame 2 thereof. It will be understood that by virtue of the gearing relation embodying the

several gears

39, 31, and 38, the driven rolls [4 and I comprising the twister feed mechanism be rotated in the same direction. The driven rolls i4 and i5 will insure a positive feed of the cord 9 to the twisting apparatus and the collecting spool 22 disposed therebelow. The idler roll it associated with the driven rolls i4 and i5 is advantageously weighted to insure constant frictional engagement between the cord 9 and the driven rolls i4 and IS in the operation of the apparatus.

The burnishing roll I1 is supported by a shaft 4| mounted in a bearing bracket 42 on the frame 2 at one end thereof, and a boss 43 in the end plate 33 at the other. A pair of spaced brackets 44 are arranged to adjustably support the weighted idler roll IE to enable it to be raised and lowered with respect to the driven rolls i4 and I5 to facilitate the threading up of the apparatus. A single idler roll it is provided for each individual cord 9 at each position on the machine extending from end to end thereof.

A portion of the shaft 29 extending through the bearing bracket 3i rotatably supporting the driven rolls I4 and i5 carries a single pulley 45. A dual idler pulley 46 embodies a pair of

pulley segments

41 and 48 of different diameters and vis rotatably supported by bearing bracket 49. The

drive for pulley 46 is achieved by means of a belt 50 which is trained over the pulley 45 and pulley segment 41. x

The pulley 46 in turn drives a smaller single pulley 5! by means of belt 52 which contacts the larger of the pulley segments 48. The pulley ii is mounted upon the end of the shaft 4| supporting and driving the burnishing r011 i'l. By virtue of the pulley sizes employed in transmitting the drive from the shaft 29 to the shaft 4|, the' burnishing roll I1 is driven at a speed somewhat higher than the rate of delivery of the cord from the twister feed mechanism embodying the several driven rolls l4, l3 and idler roll It will be readily understood that any desired conventional form of drive can be substituted for that shown and described. Moreover, any desired driving relationship can be achieved b changing pulley sizes, gearing, and the like. It is contemplated by the present invention to rotate the burnishing roll I'I at a speed such that it will exert a slight tension upon the cord 9 being delivered from the twister feed mechanism embodying the rolls I4, I! and I6, thereby permitting a slight slippage of the cord 9 with respect to the surface of the burnishing roll IT.

The slipping action of the cord 9 on the roll 7 i1 causes the cord to roll upon itself and, thus.

pressed into the body of the cord as it is subsequently twisted. To prevent excessive axial pro- 'gression of the cord, a restraining collar 53 is positioned on the outer periphery of the burnishing' roll it adjacent the path of contact of the cord upon the surface of the roll and defining a more or less restricted area over which,the cord may move along the roll.

The use of the collars 53, one for each cord 9, on the burnishing roll ll serves to increase the effective surface of contact with the traveling cord 9. It will be understood that when the cord 9, is disposed in contact with one face of" the collar 53, as well as the roll H, the burnishing action thereon is produced both by the edge of the collar and by the portion of the roll surface adjacent thereto.

If desired, heat may be supplied to the burnishing roll IT to facilitate the smoothing and drying effect upon the cord 9. This heating step may be accomplished in any one of several different ways of which the method illustrated in Figure 5 of the drawings is but one. In the illustrated modification of the invention, a burnishing roll 54 is provided with a perforated hollow shaft 55 for introducing steam from a suitable supply source 56 to the interior of the roll. The steam supply 59 is connected to the shaft 55 as by means of piping 5] and coupling 59. Thus, the roll 54 may readily be uniformly heated to any desired temperature to effectively dry and burnish the cord 9.

Other modifications may be made in the apparatus of the invention without in any way departing from the spiritor scope of the invention. pulley drive for the burnishing roll might advantageously be supplanted by a gear drive unit. Moreover, any form of heating of the housing is satisfactory.

While in accordance with-the patent statutes one best known embodiment of the invention has been illustrated and described in .detail, it is to be particularly understood that the invention is v not limited thereto or thereby, but that the inventive scope is defined in the appended claims.
