Definitions
- This invention relates to reels of the type adapted to receive and advance a strand through a helical path over a peripheral surface thereof and particularly to the threading or lacing of such reels.
- the term strand includes yarns, threads, cords, monofilaments and continuous filamentary bundles of any type which may be passed overa thread-advancing reel.
- Thread'advancing reels may be readilylaced or threaded when the reels are exposed and/or supported at one end only and operated at the usual speed of strand travel of conventional rayon yarn manufacturing practice.
- the lacing problem is greatly aggravated by strand speeds which require the rotation of the thread-advancing means at peripheral rates ranging above 150 meters per minute.
- the thread or strand tends to be thrown away from the strand-supporting surface of the rolls by centrifugal force, and moreover, the strand is traveling so rapidly that it is physically impossible for an operator to either see or manually catch the advancing end or a specific portion of the strand and lead or guide it, through a series of thread-storing thread-advancing reels or other thread-handling devices.
- a principal object of the invention is to provide means and a method for introducing the strand upon the rotating surface of the thread-advancing means. It is another object, to facilitate the lacing of a strand over a series of rotating strand-advancing reels. Still another object is to provide means and a method particularly adapted for lacing thread-advancing means which are either enclosed or supported at both ends with respect to an axis of rotation. It is a further object to provide said lacing means by a simple modification of existing equipment. Other objects, features, and advantages will become apparent from the following description. of the invention and the drawings relating thereto in which- Fig. 1 is a diagrammatic pictorial view illustrating apparatus as well as a method of the invention;
- Fig.2 is a side elevation of-the embodiment of Fig. 1;
- Fig. 3 is a fragmentary pictorial view of a reel bar embodying the invention.
- Fig. 4 illustrates an element which may be fitted over the end of a reel bar of the type shown in Fig. 3 as a further modification
- Fig. 5 is a diagrammatic end view of two sets of alternately spaced reel bars illustrating the eccentricity of one set with respect to the other;
- Fig. .6 is a fragmentary longitudinal section illustrating a reel bar of modified construction in accordance with another embodiment of the invention.
- Fig. 7 illustrates in partial section a simple portable the reels.
- Fig. 8 illustratesa modified shaft-engaging portion for the device shown in Fig. 7.
- a thread-advancing reel is simply and eflfectivelylaced singlyor in series by diverting or leading a running thread into contact with one or more thread gripping, elements positioned along a peripheral marginal surface of the thread-advancing reel at one side of its thread-carrying surfaces.
- a thread-advancing reel 8- With its thread-supporting surface-9 filled with thread .and the thread it) ready to be transferred' to a thread-advancing reel 12.
- a hook or pick 14 has been inserted under one of the most advanced coils of the thread 10 and lifted from a'peripherally disposed surface of the rotating ree1-8 carrying thread 'at the approximate area of departure for the thread from the reel 8.
- the thread travelsaround thepick while supportedthereby,
- the hook With the hook now'extending within the loop of strand, the loop is promptly wrapped: onto the reel12.
- the sectionof the loop returningto the reels is immediately put under such tension as to breakzit.
- the section of 'theploop passing toward the reel'12 is, on the otherhand, subjected to little tension 'becauseit is beingfed toward the reel 12 at substantially, its peripheral speed.
- the engagement with a receivingreelof a loop of strand withdrawn from a, supply reel in the maner justdescribed explains the manner in which the strand is automatically broken in the operation :of thevarious "modifications of the lacing apparatus hereinafter'described.
- the hook 16 or-hook 16a of: the reel 8 is positioned orsecured to any marginal portion of the surface of' the reel 12 which is out of alignment with the normal line of departure of the thread 10 leaving the reel 8, so that asrthe reel 12;rotates to-collect the strand which;follows the portion caught by the 'hook 16 onto the reel surface, theadvancing end of the strand is effectively folded under one or more convolutions of the strand wound on the .reel immediately thereafter.
- the strand winds upon itself in this manner until normal operating alignment of thestrand is established between
- the thread-advancing action of the reel carries the first-formed convolutions off the hook and the marginal surface provided for lacing the reel toward and onto the normal thread-supporting surface.
- the convolutions first formed are more or lesswrapped upon each other to form a band which is carried intact across the thread-supporting surface to the thread-discharging region of the reelu
- the formation of such a band ensures the transfer of the strand end to the stranddis charging region of the reel surface without the end he comingloose or caught by other portions of the machine which may be spaced at close clearance withthe threadadvancing reels.
- Fig. 2 illustrates two thread-advancing reels positioned to support and transfer the thread through predetermined thread-storage ranges a and b.
- the thread makes its initial contact withthereel 12 at thepoint 15after normal operationis established. This point is determined by the point at which the thread 10 leaves the reel 8, both points lying in a plane at right angles to the reel axes when these axes are parallel.
- the dotted line 1% indicates the path along which the thread is held or diverted when using the pick 14 to engage the hook 16. It may be readily seen, therefore, that as the thread is passed around the marginal portion of the surface of the reel 12 outside of the range [2 that the thread-advancing action of the reel will quickly tend to transfer convolutions of thread formed on the marginal portion toward the threaddischarging end of the reel.
- the normal path of the strand intersects the surface of the reel 12 at one extremity.
- the reels are therefore self-cleaning with respect to the marginal portions of their surfaces used for lacing purposes; any tangles or snarls which are formed about the hook 16 are removed therefrom and laterally transferred to the opposite end of the reel by normal thread-advancing action.
- Fig. 3 illustrates an end portion 20 of a thread-supportl ing element or bar of a type conventionally used in the construction of thread-advancing reels but adapted to the present invention.
- Such reels comprise two sets of these bars supported in alternately spaced arrangement (illustrated in Fig. 5), of which one set moves relative to the other set to produce thread-advancement in a direction parallel to the axis of rotation of the reel.
- the ends of one or both sets of bars of the strand-receiving end of the reels may be provided with a roughened surface at 22 adapted to grip a thread which is held into substantial tangency with the periphery of the reel adjacent the roughened surface and then brought into contact therewith during the lacing operation.
- the bar 20 will ordinarily comprise a corrosion-proof material such as glass, a resinous material such as a phenol-formaldehyde prod- Preferuct, a resin-bonded fabric laminate, stainless steel, or a bar to provide a surface to which a separate strandgripping element 21 may be secured.
- a sleeve or collar 24 may be provided such as shown in Fig. 4 adapted to fit over the end of the bar 20.
- the element 24 is preferably made of a resilient material such as a vulcanizable composition containing a rubber or a rubber-like polymerizate, but various plastics or resins of a flexible nature will also be employed.
- a resilient material such as a vulcanizable composition containing a rubber or a rubber-like polymerizate, but various plastics or resins of a flexible nature will also be employed.
- the less resilient and flexible materials selected for this use must be molded with a greater degree of precision in order to tightly fit the ends of the bars 20.
- any strand-gripping means provided in the marginal surface of a thread-advancing reel must be such as to permit lateral movement of the thread in response to the thread-advancing action of the reel.
- a saw-tooth surface, such as that of the element 24, is satisfactory in this respect because it provides lateral ridges 26 along which the thread may slide during lateral advancement but which also grip the thread.
- the movement of the bar relative to the adjacent bars should be such as to permit disengagement of the bar with the strands extending across and supported by the surfaces of the adjacent bars.
- Fig. 7 illustrates a portable hand device which may be held against the end of a reel shaft to produce rotation of a member and which has a purpose similar to that accomplished by the permanently mounted strand-engaging hooks 16 of the earlier described apparatus.
- the device 36 of Fig. 7 comprises a shaft 32 rotatably supported within an annular handle 33 by bearings 34 and 35. The outer races of said bearings are secured in position within the handle 33.
- the shaft 32 is cut to varying diameters to form the shoulders 38 and 39 which position the inner races of the bearings.
- the shaft 32 may be provided with an adapter of any type, which may be brought into engagement with a portion of the reel at reasonable pressure exerted manually, to connect the shafts 32 and 50 in driving relationship without any loss of rotative speed therebetween.
- an adapter 48 is appropriately recessed so that it may be jammed onto a nut 49 in threaded relationship with the rotating reel shaft 50.
- the adapter comprises an outer shell and an internally tapered cup 52 contained therein which is preferably formed from a resilient material.
- the cup has an inner surface tapered with respect to the shaft axis so that the cup may be more readily jammed into non-rotatable relationship with the nut 49 even though the reel is rotating at several hundred revolutions per minute.
- the interior surface of the adapter may be frusto-pyrarnidal or frusto-conical.
- an adapter 30a illustrated in Fig. 8 may be mounted in place of the adapter 43 of Fig. 7, and the device brought into engagement with a shaft 5% having an end portion suitably recessed to receive the adapter.
- the cooperating surfaces of either, or both, the adapter 30a or the recess 54 may be roughened, grooved, or ridged to obtain positive engagement therebetween.
- the device 30 is particularly useful when lacing reels which are supported at one end only regardless of whether the strand is advanced away from or toward the supported end.
- the operator may hold it into engagement with the reel with one hand while lifting a strand by means such as the pick 14 from an adjacent reel with the other hand.
- the thread is then led into the clearance 56 which defines the space between the surface of the reel and the path of revolution swept by the arm 41.
- the strand is promptly picked up by the arm 41 which holds the caught portion of the strand in fixed relationship with the adjacent portion of the reel surface; in this manner the strand feeds onto the reel surface
- the strand-receiving portion of the reel surface is nearest the unsupported end of the reel, the convolutions of strand immediately formed are wound over each other until, as a result of the threadadvancing action of the reel, the convolutions formed along the lacing area of the reel are carried into the normal thread-supporting surface of the reel.
- the portion of the strand caught upon the arm 41 is pulled off the arm and carried laterally toward the other end of the reel.
- the strand When the strand-receiving portion of the reel surface is nearest the supported end of the reel, the strand may be first guided or led upon the strand-discharging portion of the strand-supporting surface.
- the strand passing onto the reel from an exterior source quickly aligns itself with the normal strand-receiving portion of the reel within a couple of revolutions of the reel.
- the portion of the strand attached to the arm 41, having been wound about the strand-discharging surface of the reel, is advanced off the end of the reel and the device 30 is thereupon readily disengaged from the strand.
- the method comprising the steps of winding the strand onto the first-named device in juxtaposed windings until the loading thereof has progressed beyond the desired point for withdrawing the strand from the device toward the second device, lifting a winding of the strand away from said point and gently stretching successive portions of the strand to form a running loop thereof, bringing the loop into positive engagement with the moving strand-supporting surface of the second device, and catching the loop with a surface of the second device whereupon the section of the loop returning to the first device breaks and the section of the loop advancing toward the second device is held thereby to advance the strand to form windings about said strand-supporting surface.
- the method of loading a rotating thread-advancing reel and transferring strand therefrom to another rotating reel comprising the steps of winding the strand onto the thread-storage surface of the first-named reel until excess windings have collected adjacent the stranddischarging end of the first-named reel, hooking a winding from said strand-storage surface at a predetermined point corresponding to a desired loading of the reel, and lifting the hooked and running strand gently without breaking it to form a loop, and positively engaging the strand of the loop with the peripheral surface of the second-named reel whereupon the section of the loop returning to the first reel breaks and the section of the loop advancing toward the second reel is secured to the periphery of the second reel whereby the strand is advanced longitudinally to form windings about the second reel.
