Definitions

  • An apparatus for accurately applying edge ribbons to a continuous fabric strip of material which includes .a pair of sensing devices for sensing the lateral positions of the edges of the strip material and mechanism for maintaining one of said edges of the strip material in registry with one of a pair of edge ribbon turnover devices and for maintaining the other edge ribbon turnover device in registry with the other edge of the strip material.
  • This invention relates to means for enclosing the edge of strip material in a narrow folded strip of rubber, and has for an object to provide an improved apparatus for applying a thin strip of rubber to one, or both, of the lateral edges of strip material and for folding the strip rubber thereabout.
  • the present invention relates to the binding of the edges of fabrics, such as low-angle bias-cut tire breaker fabrics as used in the construction of radial ply tires.
  • an apparatus operating upon fabric strips which are used in the manufacture of pneumatic tire casings The purpose of binding the strips is to insulate the edges thereof from the remaining portions of a tire carcass.
  • This is customary practice in pneumatic tire manufacture. It is known, to splice together a series of bias-cut fabric strips so as to form a continuous length. It is also known to simultaneously therewith slice a Wide strip of soft rubber stock into a plurality of strips, forming ribbons which are carried in continuous movement to the fabric to which they are attached by folding around the edges thereof.
  • Such an arrangement is for example described in U.S. Pat. 2,060,269 issued on Nov. 10, 1936 to George F. Wikle.
  • the known edge applying apparatus has been found to be no longer satisfactory. Slight unavoidable variations in the lateral position of the continuous strip of fabric in moving through the apparatus and/or slight variations in the width of the fabric strip result, with the known apparatus, in non-uniformly applied edge ribbons.
  • the purpose of the present invention is to provide an improved apparatus for binding a strip of fabric or other material, with a thin folded rubber ribbon, rapidly and economically and with uniformity as to the width, thickness and relative position of the rubber edging.
  • binding strip material such as fabric strip employed in the building of tire casings
  • a folded edging of thin, unvulcanized sheet rubber ribbon stock it has heretofore been the practice to apply the rubber with a pair of fixed folding fingers such as taught by the Wikle patent.

  • the present invention comprises a frame 1 rotatably supporting thereon a breaker fabric supply conveyor 10 for supplying a strip of breaker fabric 2.
  • a conventional take-up spool 20 is journalled at the end of an arm 20a pivotally carried by frame 1.
  • the spool 20 is maintained in tangential contact with a drum 25 journalled on frame 1 and driven by a conventional drive means such as an electric motor 25a connected thereto in conventional manner for rotating the drum 25 in counterclockwise direction as viewed in FIG. 1 so as to advance the fabric 2 in the direction of the arrows.
  • the conveyor 10 and the spool 20 are positioned at the same end of the apparatus but at different elevations with respect to each other.
  • the fabric strip 2 is advanced along a generally U-shaped path, leading first to a fabric centering means 30 carried on frame 1 and then through an edge ribbon applicator means 50.
  • an edge ribbon supply and delivery means 40 Positioned on the frame 1 above the path of the fabric strip in the region of means 50, is an edge ribbon supply and delivery means 40 for supplying a pair of ribbons to opposite edges of the fabric 2, as it advances toward the edge applicator means 50.
  • the fabric strip 2 being delivered by supply conveyor 10 whose speed is synchronized with that of drum 25 driven by drive motor 25a, passes initially under a guide roller 11 and from there over the first and under the second of a pair of parallel centering rolls .12 and 13 respectively, of the conventional centering means 30 as best seen in FIG. 5.
  • the parallel rolls 12 and 13 are rotatably journalled between a pair of parallel plates 14 and 15 which later are, in turn, pivotally supported on movable blocks 14- and 15' respectively.
  • blocks 14' and 15 are supported for movement along symmetrical, oppositely inclined, paths by means of the oppositely inclined symmetrical pairs of guide rods 17 and 18 which are afli'xed to the frame 1.
  • a hydraulic actuator 19 parallel to the guide rods 17 is connected to the block 14' for movement of the block 14' along guide rods 17 to tilt the rollers 12 and 13.

  • the direction of actuation i.e. tilt of the rollers 12 and 13 may be controlled through suitable valves (not shown) which form part of a control means 16a which latter in turn is controlled by a pneumatic or photoelectric edge sensing head 16 of conventional design.
  • the sensing head 16 is fixed to frame 1 adjacent the path of an edge a of fabric strip 2 and detects the position of said edge as the latter advances towards the edge ribbon applicator means 50, so as to keep said edge a in registry with a turnover blade 50a to be described in greater detail hereinafter. Whenever the edge a of fabric strip 2 shifts laterally with respect to the detector 16, the latter senses such shift in conventional manner and in response thereto actuates the control means 16a.
  • the actuating means 19 is actuated in a direction to tilt the rollers 12 and 1:3 angularly from the illustrated central position in either clockwise or counterclockwise direction depending upon the direction of lateral shift detected by head 16, so as to urge the strip 2 therebetween to shift laterally until edge a thereof is back in its predetermined position in registry with blade 50a.
  • the centering means and the operation thereof is known to those skilled in the art and is not therefore described in greater detail herein.
  • the fabric strip 2 is thus maintained in a position in which its edge a remains in registry with the blade a as hereinafter described in more detail.

  • the elevation of roller 510 is such that the peripheral surface thereof is located below and substantially tangent to a horizontal plane which in turn is located below and substantially tangent to the peripheral surfaces of the rollers 51a and 51b so that the fabric strip 2 will be guided along a substantially horizontal path intermediate the spaced rollers 51! and 510.
  • the fabric strip 2 After passing over roller 51c and then downwardly between rollers 51c and 51d and under roller 51d, the fabric strip 2 passes under an additional parallelly disposed guide roller 51e and thence over the drum 25 onto take-up spool 20.
  • rollers 51a through 51d form part of an edge strip applicator means 50 for applying edge ribbons 3a and 312 (FIG. 9) to the respective edges a and b of fabric strip 2 so as to form a strip assembly 4, as will be described in more detail hereinbelow.

  • Piston 49a in turn, is rigidly connected to the bracket 47, thus completing a feedback for continuously urging the bracket 47 and the guide roller 46b, and the edge detector 48, mounted thereon, to remain in registry with the marginal edge b of strip 2.
