No. 420,584, Dec. 23, 1964. This application Feb. 25, 1966, Ser. No. 536,522

15 Claims. (Cl. 2859) ABSTRACT OF THE DISCLOSURE This application is a continuationin-part of copending application Ser. No. 420,584, filed Dec. 23, 1964, now abandoned.

The present invention relates to the winding of strand material into package form. More particularly, it relates to improved method and apparatus for winding a plurality of spaced-apart continuous strands into a single package and forming a series of superimposed bights. More specifically, this invention relates to method and apparatus for producing a plural strand package wherein the strands are comprised of a multiplicity of filaments drawn from a single source, and to a method for winding the strands onto a package in spaced-apart relation which permits simultaneous unwinding of the individual strands.

The advantages of strand material as a reinforcing agent for plastic laminates is recognized by those working in the art. It has also been recognized that the reduction of the number of filaments per strand improves the surface of the laminate. The improved surface may be attributed to the reduction in the diameter of the strand, which reduction contributes toward a smoother surface finish and toward being wetted out more completely by the resin.

The general object of the present invention is to provide method and apparatus for winding a plurality of continuous strands onto a single package wherein the strands are maintained in spaced-apart relation.

A further object of the present invention is to provide method and apparatus for winding a plurality of continuous strands onto a package, a new type of combing device to facilitate the startup of the winding operation and to insure that the strands are maintained in spaced apart relation.

Apparatuses which have been previously employed in producing a bulk strand product for use as a reinforcing material for resin laminates are disclosed in US. Patent No. 3,056,711 to Frickert and in US. Patent No. 3,072,- 518 to White. In the method and apparatus disclosed in Frickert Patent No. 3,056,711 the groups of strand material are intermittently compacted in intimate side-byside unitary relation in spaced zones along the length of the product to effect an integration thereof in the spaced zones. The instant invention is distinguishable from Frickert in that method and apparatus are provided for maintaining the groups of strand in spaced relation at the time that the strands are being wound onto the package being formed. The instant invention, while more closely related to the method and apparatus disclosed in the Patent No. 3,072,518, White, provides improved method and apparatus to facilitate the startup of the winding operation and to insure that the strands are maintained in spaced relation during the winding operation.

In accordance with a preferred] embodiment of this invention, a multiplicity of filaments are advanced from a source; during s-tartup, the filaments are divided manual- 1y into two groups; and each group is converged into a single strand at its respective gathering or converging station. The strands are further advanced to a winding station where the strands are initially wound at the terminal portion of the winding support collectively. The process thus far described may be termed the first phase of the winding procedure. The strands then seek their own normally perpendicular advancing paths and are wound in spaced-apart relation during a second phase of the winding procedure. The attendant operator at the filament source then splits each of the two strands into two or more bundles by removing the primary converging device and positioning instead of secondary gathering or converging device having an increased number of converging grooves corresponding to the number of bundles to be formed. During this third phase of the winding procedure, the attendant operator positions a combing device having finger elements or tangs insertable between the formed bundles. The tangs are inserted between the bundles initially at the converging station. During this third phase of the winding procedure, the bundles would normally tend to converge together at the winding station. However, the combing device is carried downwardly to a position adjacent to the traversing mechanism at the winding station. The tangs of the combing device then serve to limit the axial movement of the separate bundles as they are being traversed and maintain the bundles in spaced-apart relation as they are wound on the winding mandrels.

Other objects and advantages of the invention will become apparent during the course of the following description when taken in connection with the accompanying drawings.

The present invention may be used in the formation of filaments, strands, and yarns from any one of a number of materials such as glass, artificial silk, nylon or cellulose acetate. In the present case, the invention will be described in connection with glass since the invention finds particular utility in the production of glass strands.

Referring to FIG. 1, there is shown a receptacle adapted to contain a supply of molten glass and having a plurality of small apertures or orifices in the botton base portion thereof through which molten streams of glass flow by gravity or are exuded from the receptacle 10. Filaments 12 formed from the streams of molten glass are drawn downwardly at high speeds and are gathered into one or more strands 14A and 14B by the action of one or more fiber gathering or converging bodies 16A and 16B. The gathering bodies 16A and 16B may form a part of a filament-treating station 18 where the filaments are customarily treated with suitable treating or lubricating liquid by contact with the wiping surface 20 of the treating station 18. The wiping surface 20 is rotated to continuously provide fresh treating material 22 to the filaments 12 as they pass thereover.

In the embodiment illustrated in FIG. 1, the treating station 18 comprises a base 24 for supporting a drive motor 25 operatively connected to the roller applicator 26 through gears 28 and 30. The base 24 also supports the doctoring blade 32, which blade 32 controls the flow of the treating material to the surface 20 of the applicator roll 26. The treating material is fed to the roller 26 just prior to the point of contact through conduit 34 that is connected to the treating material supply source. A catch basin may be provided beneath the roller 26 to catch the excess treating maetrial falling from the roller 26. From this basin 36 the treating material may be return to the treating material supply syestem through conduit 38.

Beneath the motor base 24 is a support 40 for supporting the primary converging or gathering wheels 16A and 16B. The primary gathering wheels 16A and 16B are mounted on a pivotable arm 42 for movement into and out of engagement with the filaments 12. At an opposing end 44 of the arm 42 is what may be termed a secondary converging wheel 46 defining a plurality of grooves 48 for suitably converging a corresponding number of strands 14A2 and 14B2.

In a typical installation such as shown in FIG. 1, the melting crucible generally has 400 orifices. The operator manually splits the 400 filaments into two groups or strands 14A and 14B of 200 filaments each. Each of these strands 14A and 14B is threaded over the primary gathering wheels 16A and 16B for advancement to the winding station 50 and onto the terminal portion 51 of the winding mandrel 52 during the initial winding procedure. Adjacent to the winding mandrel 52 is a primary traversing mechanism 54 for imparting a progressive and a regressive motion to the rotating supports or tubes 56. During the first phase of the winding procedure, both of the strands 14A and 14B are wound on the terminal or flange portion 51 of the winding mandrel 52. At this time, the primary traversing mechanism 54 is not operating. However, upon commencement of rotation of the primary traversing mechanism 54, the two strands 14A and 14B are guided to their respective supports 56 on the Winding mandrel 52. The first strand 14A moves to its respective primary traverse 54A and the second strand 14B moves to its corresponding primary traverse 54B. During the second phase of the winding procedure, the attendant operator at the melting receptacle 10 pivots the primary gathering wheels 16A and 16B out of engagement with the strands 14A and 14B and consequently the strands 14A and 14B are caused to come into engagement with the secondary gathering wheels 46 which automatically separate the two primary strands 14A and 143 into four separate bundles which are gathered into what may be termed secondary strands 14A2 and 14B-2. Each of the secondary strands 14A2 and 14B-2 contains approximately 50 filaments each. It will become apparent that the number of final strands can be varied by providing a suitable number of converging grooves 48.

Combing mechanism 60, up to this time, has been in a retracted or nonoperative position. However, after the two primary strands 14A. and 14B have been split into secondary strands 14A2 and 14B-2, the comb 62 is pivoted so that the tangs 64 of the comb 62 are inserted between the divided filaments 14A-2 and 14B2. The comb 62 is on carriage means, for pivotal movement, including a support 66 carried by a slide rod 68 which slide rod serves to guide the comb 62 as it is lowered from a retracted position at the treating station 18 to an advanced position at the winding station 50. The support 66 is moved through means comprising a driven cable 70.

The cable 70 is guided over pulleys '72, 74, 76 and 78 to cable drum 80. When the drum 80 is rotated in a clockwise direction the support 66 is raised; when the drum 80 is rotated in a counterclockwise direction the support is lowered. Suitable drive means, such as motor 81, is provided to rotate the drum 80.

=Initially, upon the start-up winding of a new strand package, the comb 62 on the support bracket 66 is elevated from a lower position to the topmost position on the guide rod 68. As the support 66 approaches the topmost position, pivotal arm 82 engages stationary pivot stop pin 84. Further upward movement then causes support arm 86 to overcome the resistance of the spring 88 and to rotate and move the tangs 64 of comb 62 out of the normal position, within which position the tangs 64 separate the strands 14A2 and 14B2. The support 66 then engages the actuating lever 89 of upper limit switch 90. Actuation of the switch 90 outs oif the power to drive motor 81 and further upward movement of the support 66 is automatically discontinued.

Subsequently, when the cable 70 travels in a counterclockwise direction, as viewed in FIG. 3, the support bracket 66 moves downwardly, the support arm 86 rotates counterclockwise, by virtue of the action of spring 88 on arm 94, until arm 94 bears against support bracket 66. This later action serves to position the comb 62 and tangs '64 in the desired location in respect to the strands 14A2 and 14B- 2. The support bracket 66 continues to move downwardly, with the comb 62 combing the strands 14A-2 and 14B2, until the support 66 engages the actuating lever 96 of lower limit switch 98. Actuation of the switch 90 shuts off the motor 81 and the downward movement of the support bracket 66 is stopped. The support bracket 66 together with the comb 62 and the related appurtenances remain in the lower position during the remainder of the package Winding cycle. During this time the comb serves to maintain the strands 14A-2 and 14B2 in spaced-apart relation.

One of the results of moving the comb 62 down adjacent to the traverse mechanism 54 is a change in the effective pivot point of the individual strands 1-4A 2 and 14B2 during the winding cycle. As the strands 14A2 and 14B2 approach the ends of their traverse, they bear against and pivot about the side surfaces of tangs 64. Because each of the strands 14A2 and 14B-2 has its own pivot point(s) and because the angular displacement, of a strand about a lower pivot point it greater than the angular displacement of a strand about a high pivot point (even though the axial displacement may be equal), there is little tendency for the individual strands 14A2 and 14B2 to become entangled with one another, particularly at the limits of their traversing strokes.

A preferred embodiment of the apparatus of this invention includes the secondary converging means 46; however, in some instances by carefully positioning the tangs 64 of comb 62 between the filaments 12 at a zone intermediate the primary converger 16A and 16B and the roller applicator 26, the comb 62 will perform the function of the secondary converger 46. In such instances, the secondary converger 46 may be omitted.

While power means are shown in connection with the slide mechanism it will be apparent that a pull chain can be provided which the attendant operator may employ to manually raise the comb from the lower position to the upper position and that suitable latching means may be provided at the uppermost position to retain the comb when desired. In such an arrangement the comb will descend by gravity when the operator releases the latch.

In the embodiment illustrated in FIGS. 7-9, the converging device 46A serves a dual function, that of a converger for converging the filaments 12 into a plurality of strands 14, and that of a combing device for combing the strands 14 after they are formed. The converging device 46A is supported for movement with slide blocks 66A along support bracket 69. The slide block 66A may be moved through means equivalent to that shown in FIGS. 1-5 in connection with support 66, from a retracted position, near the filament forming station comprising the receptacle 10, to an advanced position, which is toward and preferably near the traversing mechanism 54 and the winding mandrel 52. During the advance movement, the ridges 47 between grooves 48 serve as combing fingers or tangs which maintain the several strands in spaced relation. In this embodiment the height of the ridges, as measured from the bottom of the grooves, may be con sidered as defining the longitudinal extent of the fingers.

Initially, upon the start up winding procedure of a new strand package with the apparatus shown in FIG. 7 the converger 46A is in the elevated or retracted position. The attendant operator grasps all of the filaments 12 to be wound in a single package in a bundle and brings the bundle into contact with the converger 46A to divide the filaments 12 substantially equally among the number of grooves 48 corresponding to the number of strands 14 to be formed. The several bundles are grouped at the winding mandrel 52 and started to be wound. At this time, the traversing mechanism 54 is not operating. The converger 46 is then advanced, by being lowered to a position near the traversing mechanism 54 (FIG. 9). The several strands 14 are spaced across the traversing mechanism 54 and across the package to be formed. The traversing mechanism 54 is started and the main winding operation commences with the strands 14 being wound in spaced apart relation.

FIGS. 7-9 also illustrate a further feature of this invention, that is of providing a filament treating station which is advanced and retracted in movements corresponding with the advancement and retraction of the combination converger and combing device 46A. A manifold conduit 100 is provided for each of the treating stations and for convenience may be supported by and for movement with a slide block 66A. The manifold 100 is suitably connected to main feed line (not shown) by means of a flexible tube 104 to accommodate movement with the slide block 66A. A number, corresponding to the number of grooves in converger 46A, of individual feed tubes 106 extend from the manifold 100 and lead directly to the top surface of the converger 46A to supply a constant flow of liquid treating material to each of the converger grooves 48. A valve (not shown) may be inserted in each of the said tubes 106 for regulating the individual flows. The provision of such feed means for feeding liquid treating material insures optimum application, particularly of lubricants to the individual filaments .12, the formed strand 14, and to the converger grooved surfaces and thus materially deters intra-abrasion of the filaments 1 2.
