' My inventionrelates to a device for wrapping longitudinally wrapping lengths of material, such as bead cores, used in building pneumatic tire casings, withfabric or other 1naterial andmore particularly to a device 0 mounted to apply spring pressed toward the which will apply the wrapping 'a number of times about a length of material.

In the accompanying drawings which illustrate one embodiment of my invention Figure 1 is a side elevation of the device, the wrapper being omitted in the interest of clearness,

Figure 2 is a plan View of the structure 7 shown in Figure 1,

Figures 3', 4 and 5 are diagrammatic sections showing the wrapping steps, substantially at the lines 33, 44: and 5-5 of Figure 2.

Figure Gis a detail of the mounting of the wrapping rolls.

instrumentalities. As shown in Figure 1 the bead core 5, drawn from any suitable source of'supply, is applied to the fabric strip 6 as the latter passes over a roll 7 from tension rolls 8 and 9, a grooved guide roll 10 press ing the core into adhering contact with the fabric strip. The assembled core and fabric then pass to a preliminary wrapping means comprising a grooved wheel 12 and folding blades 14 and 16. As shown in Figures 8 and 2, the core is applied off center of the strip and blade 16 applies the short edge of the fabric to the core, while blade 14 underlies the longer edge of the fabric and assures the application of the strip to the side-of the core in position to be engaged by the first of the series of wrapping rollers 18. A second guide roller 19 maintains the core in contact with a substantial are of the wheel 12.. The'wrapping rollers 18, which are preferably grooved are mounted in opposed pairs as is shown in Figure 2 and are supported by frames 20 secured to table 2 at 21.

The rolls 18 are carried'in forked menibers 22 adjustably mounted in frames 20 by set screws 23. One roll of each pair is spring 1925. Serial No. 41,294.

is clearlyshown inFigures 4 and 5. This angular relation o'fthe rolls imparts a turnmg or twlstmg motlon to the core as the latter passes through the rolls, thus rolling the core into the wrapper. Figure 4: shows the wrapping about half completed while Figure 5 shows the wrapping nearly completely applied. Fromthe last pair of rolls 18 the Wrapped core passes over wheel and around a tension wheel 31 mounted at one end of a lever 32 pivoted to. a bracket 83 secured to table 2. A weight 34attached to the other end of lever 32 urges wheel 31 against vwheel 30. The shaft 35 of wheel 30 is connected for rotation to any suitable source of power, not shown, and. wheel 12 is driven from shaft35 by means of a sprocket chain 36 passingaround sprockets 37 and 38 mounted respectively on shaft 35 and shaft 39 of wheel 12. 1

The operation may be summarized as follows: The core and'fabi'ic strips are brought together as they enter between rolls 7 and 10, the core positioned adjacent one edge of the strip. From rolls 7 and 10 the assembly passes to a preliminary. wrapping means vcomprising a grooved wheel 12 and co-operating folding blades 14 and 16 which bring the wrapper into smooth contact with a major portion of the circumference of the core as sho'wn in Fig. '3, aguide roll 19 maintaining the assembly in contact with a substantial are of the roll 12. The assembly then passes to the first of the inclined wrapping rolls 18 which roll the core into the fabric, vas.indicated in Fig.fl, succeeding rolls 18 continuing 'therolling action until the core has been completely rolled longitudinally into the strip 6. v The core in its completely wrapped condition passes around wheel 30 s r n eaeor am ns5 m i g the and tension Wheel 31. Rolls 12-and 30 being positively driven advance the assembly through the machine, Wheel 31 through Weight 34 applying sufficient tension to maintain this driving relation. The assembly having been initially threaded or led through the machine the operation proceedsas a continuous operation, the machine being stopped to permit splicing of new lengths to the ends of core 5 and Wrapper 6 before the ends of the exhausted-supply enter rolls 7 and 10.

lVhile I have shown my invention'applied tothe Wrapping of bead cores it Will be understood that my invention is not limited to such use and theword coreis used in the claims in a generic sense.
