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 over a thread-advancing reel.
  • Thread-advancing reels may be readily laced 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.
  • considerable difficulty is encountered in lacing reels which are substantially enclosed by housings, treating tanks, etc., or when the reels are supported at both ends.
  • 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 tend 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.

  • the strand is subject or susceptible to considerable stretching and sufficient slack may be accumulated from the strand as it runs over the pick and while subjected by the pick to tension short of breakage to extend or carry the strand to the next thread-advancing reel 12.
  • the strand and hook I4 are illustrated in Fig. 1 in dotted outline in the position wherein the strand is inserted between a hook l6 and the surface of the reel I2 during rotation of the reel.
  • the hook I 6, or hook l6a of the reel 8 is positioned or secured to any marginal portion of the surface of the reel l2 which is out of alignment with the normal line of departure of the thread vancing action of the reel'carrie the first-formed" I0 leaving the reel 8, so that a the reel [2 rotates to collect the strand which follows the portion caught by the hook l6 onto the reel surface, the advancing end of the strandis effectively folded under one or more convolutions of the strand wound on the reel immediately thereafter.

  • the thread makes its initial contact with the reel l2 at the point I5 after normal operation is established. This point is determined by the point at which the thread l leaves the reel 8, both points lying in a plane at the right angles to the reel axes when these axes are parallel.
  • the dotted line I8 indicate the path along which the thread is held or diverted when using the pick 14 to engage the hook l5.
  • Fig. 3 illustrates an end portion 20 of a threadsupporting element or bar of a type conventionally used in the construction of thread-advancing reel but adapted to the present invention.
  • Such reels generally comprise two sets of these bars supported in alternately spaced arrangement (illustrated in Fig. 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.
  • of bars of the strand-receiving end of the reels may be provided with a roughened surface adapted to grip a thread which is brought into contact therewith during the lacing operation.
  • the ends of only one setoi. the bars are roughened although thread transfer is not precluded if the ends of both sets of bars are roughened.
  • the bar 26 will ordinarily comprise a corrosion-proof material such as glass, a resinous material such as a phenol-formaldehyde product, a resin-bonded fabric laminate, stainless steel, or a metal coated with porcelain or glass.
  • a roughened surface such as the surface 22 indicated in Fig. 3 may be provided by grinding or sand-blasting the end of the bar, or by milling or otherwise removing a layer or portion from the thread-supporting side of the bar to provide a surface to which a separate strand-gripping element, 2

  • element 24 is preferably made of -a. resilient ma.- terial suoh as a vulcanizable composition $0. 1-
  • 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 sawtooth 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 when the thread-supporting surfaces of the bars 2!! occupy a position radially outward with respect to that of surfaces in circumferential alignment of alternately spaced bars.
  • 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 of the earlier described apparatus.
  • the device 30 of Fig. 7 comprises a shaft 32 rotatably meter 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 32 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 5%
  • the adapter comprises an outer shell and a 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 45 even though the reel is rotating at several hundred revolutions per minute.
  • the interior surface of the adapter may be frusto-pyrarnidal or frusto-conioal.
  • an adapter 36a illustrated in Fig. 8, may be mounted in place of the adapter 48 of Fig. 7, and the device brought into engagement with a shaft 59a having an end portion suitably recessed to receive the adapter.
  • the cooperating surfaces of either, or both, the adapter 39a 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 it from an adjacent reel with the other hand.
  • the thread is then led into the clearance 55 which defines the space between the surface of the reel and the path of revolution swept by the arm 4
  • the strand is promptly picked up by the arm 6! 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 convolutions of strand immediately formed are wound over each other until, as a result of the thread-advancing 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 caughtupon the arm M is pulled oif the arm and carried laterally'toward the other 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 conple of revolutions of the reel.
  • the portion of the strand attached to the arm 4 i having been wound about the strand-discharging surface of the reel, is advanced off the end of the reel and the de- .vice 30 is thereupon readily disengaged from thestrand.
