{ This invention relates to a device for covering round or irregular sections-f wlre or.

other articles, withl'particular reference to shaping a flipper strip about a bead core or wire, either in one continuousrin'g or in long lengths. I

It is an object of. this invention to provide an improved machine for covering bead cores or the like wherein the edges of the wrapping strip lap to formanoutstanding ridge with vide a segment wheel or former adapted to be collapsed over the core or article to. be

wrapped to press the fabric tightly therearound', either in a circumferential wrap or with a projecting edge as'in bead flipping strips. A pressure plate actuatedby a cam serves to sequentially operate the segments of the wheel astheyrevolve into position; 1 It is another object of this invention to provide an idler wheel parallel with the former g"wheel for tensioning beads. when formed as an endless circle. This idler wheel is preferwhee ably mounted on a slotted; arm to allow for suitable adj ustment. for different diameter bead rings, and the arm is pivoted and actuated by a fluid cylinder to tension the bead."

Other and further important objects of this invention will be apparent from the disclosuresin the specification and the accompanying drawings.

This invention n apreferred form) is i1 lu'strated in the drawings and hereinafter more fully described.

As shown on the drawings: The specific embodiment chosen for illustration shows a continuous cable bead 15 for pneumatic tires, about which is to be wrapped a flipper strip 16. with the edges 17 tacked together in substantially the plane of the cable bead. More generally this apparatus is intended to wrap a covering material over a core of more or less irregular outline with the core either forming anendless loop or as long continuous lengths. .The covering material may be applied asacomplete circumferential wrap or withprojecting edges'as for the bead fillers chosen forillustr'ative purposes. An adjustable feed table is provided for the dif-' ferent widths of material used with circumferential wraps as compared with projecting lappededges, andalso toregulate the overlap or stagger. of the edges, in the latter case. j

This feed table 18 is best shown in FigurelO where one guide 19 for the wrapper fabric isadjustable as shown by the slots 20. i The table as a whole is also adjustable on its support- 1 ing arm'21. The fabric is, guided to the table by a bent arm 22 whichserves to twist the fab ric into position asshown in Figure 2 The machine proper comprises a supporting bracket 23 of aforms'uitable for mounting the various elements to be described hereinaft-er. The bracket may be conveniently mounted on a pedestal 24 having a broad foot 25 carrying the operating levers if the ma; chine is to be controlledby the operators foot; The pedestal also carriesa bracket26 support ing the driving motor 27 whichis connected to the operating parts of the machine by a friction clutch 28 operated by the bell crank 29, rod 30 and foot lever 31.

A shaft 32 is fixed at 33 in the bracket 23 and carries a pressure plate 34 slidable length; wise thereof, but restrained by the key 35 from rotary motion. The pressure plate carries a series of freerollers 36 forming an arc of a circle: Between. the roller plate and the bracket 23 is a rotating disc 37 having'a; pe riphcral groove 38 to conform to the outline of the inner or lower part of'the object to be wrapped. Secured to the disc is a segmental- Wheel 39 of resilient material, each segment of which carries an outstanding" block or shoe act on the segi'nent wheel by a lever cam 41' acting against the spring pressed plunger42 in the roller plate. Each shoe of the segment wheel is beveledat its leading edge as indicated at 43 to permit the leading roller to depress the segment without shock. Succeeding rollers are so spaced as to prevent release of a segment by one roller before the next on engages the segment.

An internal gear 44 is secured in the back of the disc 37 and driven by a pinion 45 on a shaft 46 which. in turn is driven by reduction gearing 47 and worm gearing 48 connected to the friction clutch 28. The particular form of gearing shown is not essential, all that is required is to secure a desired peripheral speed of the disc 37 with a convenient control by the operator. I When using endless bead cores or loops of material to be covered, anidler wheel 49 is provided to tension the same and also to give the disc 37 suflicient driving power on'the material. This idler wheel is adjustably mounted. in an arm 50 on the shaft 51, which carries a balance weight 52 on another arm 53. This counterbalance is preferably adjusted to over-balance the idler wheel in order that the wheel may normally return to short position to permit change of bead cores after com letin the coverin 0 eration. Theidler wheel is brought into operating or tensioning position by the fluid cylinder 54 and piston 55 acting on the arm 56. A suitable fluid control valve 57 is shown mounted on the pedestal foot to enable the operator to conveniently control the fluid cylinder.

An idler roll 58, having a groove 59 conforming to the shape of the article to be wrapped, is mounted between the feed table and the disc 3.7 in a position to bring'the wrapping material or flipper strip up beneath the article to be wrapped, such as the cable bead shown. This roll serves to roll the flipper strip into contact with the lower part of the cable bead, the segment wheel then turn ing one side of the flipper strip over the top of the cable head into contact with the other edge of the strip. It will. thus be evident that the width and positioning of the flipper strip will determine whether a lap or a circumferential wrap is formed andthe feed table will also determine the stagger of the ends of the strip.

The operation is as follows: ping tire beads, a flipper strip 16 is placed on the feed table with its leading edge over the idler roll .58, and the bead core 15 placed around the disc 37 and idler wheel 49. Stepping on the control valve 57 operates the cylinder 54 to tension the bead core and forces .When wrapit into the grooves in the roll 58, wheel 49 and disc 37. The disc 37 carrying the segment wheel (39) is then caused to rotate by clepressing the foot lever 31 controlling the clutch 28. At the same time, the lever cam 41 is operated to bring the pressure plate into operative position; The tension applied to the bead core serves to force the core and the fabric down into the grooves of the roll 58 and disc 37, binding the tacky fabric to the lower part of the core and drawing the same onto the disc, where successive segment shoes 40 are depressed by the roller plate to force one upstanding edge of the fabric over the top of the bead core into contact with the other edge of the fabric.

It will be evident that the outstanding edges of the flipper strip will be vertical and tangent to the side of the core if a vertical wall is used on the disc 37 as shown. To get other angles of projection, the profile of the disc wall and segment shoes are correspondingly inclined. If the flipper strip is to be radial with respect to the bead core a slight change in the profile of the disc groove or a duplication of the segment wheel acting on side of the bead will accomplish this prising means for bringing a bead core and flipper strip together in predetermined relationship, a peripherally grooved disc adapted to advance said head core and strip, driving means for said disc, a segment wheel secured to the disc, each segment of which carries a block adapted when forced toward the disc to press one edge of the flipper strip over the bead core, and means adapted to sequentially depress the wheel segments to force the blocks into operating positionJ w 2.
