Definitions

  • the present invention relates to an apparatus and a process for making tape which can be used as cap plies, breakers and reinforcement in the carcass of tires, and in particular, an apparatus and process for making such a tape from greige fabric.
  • the tape can be produced to the dimensions of the application, such as a cap ply of a specified number of ends.
  • Cap plies that envelop radial tire belts may be used to help minimize such belt-edge separation failures.
  • cap plies were applied as a full width strip with an overlap splice.
  • the splice could pull open during curing.
  • there is a limitation on the extension of the belt since the cap ply is applied over the belt.
  • the same width of material must be applied across the whole belt.
  • a narrower cap ply tape was developed in the 1990's. This tape is spirally wound about the belt. Such a tape is made by slitting rubberized fabric. The width of the tape depends on the number of cords per inch, which varies according to the tire manufacturer.
  • the tape so produced can be non-uniform, due to the possible varying number of single end cords in each strip.
  • the potential for error and the additive variances requires allowance for excessive tolerances in the tire building process.
  • the addition of rubber to ensure good adhesion of the fabric to the tire rubber adds to the overall weight of the tire.
  • the process for making belt cord fabric is similar to the slit fabric process in that it includes treating fabric, with, for example, an rfl dip to achieve good adhesion.
  • the belt cord fabric differs in significant ways: the weft cord is identical to the warp cord, the fabric is ready-to-use in the belt building process in that it does not require slitting, and the fabric does not require a rubberizing step.
  • Step 1 a process for the preparation of a cap ply tape from single end cords using a cross-head extruder has been developed.
  • Step 1 a process for the preparation of a cap ply tape from single end cords using a cross-head extruder is commonly known as the “Steelastice process”, and is illustrated in FIG. 1 .
  • the Steelastic® process shown generally at 1 , a plurality of cords 2 and rubber 3 are brought into a die head 4 , where the cords are encapsulated by rubber to give a good adhesion to the tire rubber.
  • a tape which comprises a plurality of rubberized single end cords is thus formed.
  • the cords must be treated with a resourcinol-formaldehyde latex dip before they are brought into the die head to ensure good adhesion to the rubber introduced in the extrusion step.
  • the Steelastic® process provides improved uniformity as compared to the slit rubberized fabric process, since there no possibility of uneven slitting and hence there is exact control of the number of single end cords in the tape. Moreover, this process has reduced scrap as compared to the slit rubberized fabric process, since there are no cut cords on the edges of the tape. In addition, longer lengths per roll of tape are possible with the Steelastice process. However, the extruder and the die heads used in this process represent a major capital investment. Moreover, the tape itself is still dependent on a rubber compounding step and the addition/application of rubber as a means to ensure good adhesion to the tire rubber compounds, hence increasing weight and cost. In addition, the Steelastic® process requires above ambient pressures and temperatures.
  • the present invention overcomes the problems associated with the prior art by providing a process which is does not require the use of extruder dies as in the Steelastic® process.
  • the process of the present invention is not as labor intensive as the slit rubberized fabric process of the prior art, as it does not involve slitting of fabric. In addition, it is not as capital intensive as the slit rubberized fabric process, as it does not require a calender roll. Moreover, the process of the present invention avoids the potential for error in that it does not have a slitting step, and hence the possibility of non-uniformity due to the possible varying number of single end cords in each strip is virtually eliminated. Also, since there is no slitting step in the process of the present invention, no edge fray is created and there are no cut cords on the edges of the tape. Thus, the process of the present invention produces less scrap than the slit rubberized fabric process. Finally, the overall weight of the tire could be reduced, since there is no need to add rubber to ensure good adhesion of the fabric to the tire rubber.
  • a process for making a tape from a fabric comprises dipping a fabric comprising a plurality of single end cords in a solvent-based cement that includes an elastomeric composition dissolved in a solvent, and drying the cement so that the majority of the solvent evaporates, thereby forming a tape comprising the fabric encapsulated in the elastomeric composition.
  • the resulting ready-to-apply tape can be produced to the dimensions of the application, such as a cap ply of ten ends.

  • the width of the greige fabric is the width of the desired cap ply, typically about 1 ⁇ 4′′-3 ⁇ 8′′.
  • This fabric can be made by running a plurality of single end cords in the warp direction. The number of single end cords per inch for cap plys or carcass applications varies depending on the cord construction, and for a particular construction, depending on the tire type and the tire manufacturer.
  • a weft yarn is run in the cross-machine direction.
  • the weft yarn is an elastic yarn which is covered with cotton. The purpose of the weft yarn is to keep the single end cords in continuous, pre-determined proximity of one another.

  • the yarns may comprise polyesters, aramid fibers, rayon, glass or carbon, etc.
  • a particularly suitable yarn for use with the present invention is T-728, which is a heat stabilized 66 nylon, commercially available from DUSA International of Wilmington, Del.

  • crests 34 a mesh with the valleys 34 b of receiving roll 32 .
  • several strips of fabric may be dipped at one time. The strips of fabric stay on the crests of the press roll and in the valleys of the dip pan roll to press the cement into the spaces between the strips of fabric as they travel through the dip pan.
  • a solvated, or wet tape is shown coming out of the grooves of the dip pan roll at 33 in FIG. 4 . If several strips of fabric are dipped, guide rolls may be used at this point forward in the process to keep the strips of fabric separate.
  • the dip that is used in the dip pan is a solvent-based cement.
  • This solvent-based cement includes an elastomeric composition, which is dissolved in a solvent, such as toluene.
  • This elastomeric composition may comprise, for example, but is not limited to, a natural rubber, or a natural rubber with styrene butadiene or styrene butadiene with polybutadiene. These constituent materials in the elastomeric composition may be mixed with reinforcing agents, activators and/or plasticizers, depending on the needs of the end user.
