Definitions

  • the invention relates to a tire building apparatus, according to the preamble of claim 1, as well as a tire manufacturing method according to the preamble of claim 9.
  • the concentricity properties, and even the compressive strength of the finished tire depend to a considerable extent on the strength carriers being distributed uniformly in the carcass.
  • the invention has for its object to provide a tire building apparatus according to the preamble of claim 1 and a method according to the preamble of claim 9, which allows for low-cost production particularly good concentricity of the tire to be finished.
  • the tire building device has a building drum with a constant, ie non-stretchable, diameter, onto which building drum the inner liner is then applied directly as an air-impermeable layer.
  • the reinforcements are applied, which are preferably in turn already encased in elastomer, so that they can easily enter into an intensive connection with the elastomer of the innerliner. It is possible to vulcanize the blanking unit consisting of inner liner and reinforcing member, in order to make the connection between these two elements particularly intensive.
  • a radial winding of the reinforcing members takes place around the building drum.
  • a radial-belt tire is produced to that extent, which does not preclude the provision of additional diagonal or circumferentially-extending reinforcement inserts.
  • the strength members extend as exactly as possible radially.
  • the building drum is preferably mounted on one side and rotates with the drive shaft flanged there.
  • the innerliner can be set in a kind of wobbling motion and be wound while, so virtually no proper storage.
  • Another possibility is to provide a two-sided storage and make about pins, pins or any other means that are located in a radial inner region, a deflection of the reinforcements about the axes or waves.
  • Cutting device is cut. After the reinforcements have been rubberized, it is sufficient if they stick sufficiently on the inner liner, so that cutting off already half a turn after the winding can be made. Alternatively, of course, a cutting of the inner area after completion of all turns, so the entire winding can be made.
  • the reinforcement is guided over the middle of the free side of the building drum, and on the drive shaft side, the reinforcement is either guided tightly around the drive shaft, resulting in a substantially radial extension, or an exact radial application takes place to a deflecting pin, which is arranged adjacent to the drive shaft, on which deflecting pin the strength carrier is then deflected around the drive shaft.
  • the hardness of the reinforcement elastomers can be adjusted in any suitable manner, it being preferred that their hardness is slightly greater than the hardness of the surrounding rubber composition, in particular the hardness of the innerliner.
  • a tire according to the invention can be constructed automatically.
  • the winding device can be formed by a robot arm, and also the cutting of the circular cutout in the center in the area of the free body surface and the drive shaft side can be automated.
  • the cut can be made in any suitable manner, for example by laser or water jet, it being understood that the remaining length of the reinforcing elements is preferably selected such that a folding over of the ends of the reinforcing elements together with the rubber mixture around the surface is possible Wulstkern and optionally attached thereto core riders is possible.
  • Figure 1 is a schematic view of a building drum according to the invention of a tire building apparatus according to the invention with applied strength members, in a first embodiment of the invention.
  • FIG. 3 shows a side view of a building drum according to the invention, on which the inner liner and the reinforcement beams are applied, in a schematic representation
  • the tire building apparatus 10 shown schematically in FIG. 1 has a building drum 12, which is uniformly coated with an inner liner 14 in accordance with the invention.
  • the reinforcing member 16 is wound in the manner shown in FIG. The winding takes place in such a way that the reinforcing element 16 extends transversely over the free side 18, ie passes over at least approximately its central region 20, then runs over the cylinder outer surface or peripheral surface 22 of the building drum 12, then subsequently runs over the drive shaft side 24 of the building drum 12, and thereafter at the point opposite the first location back over the peripheral surface 22nd
  • the building drum 12 rotates by a certain predetermined angle, which corresponds to a tangential offset of the winding loops 26 of the reinforcing member 16.
  • This tangential offset corresponds to the angular distance of each winding loop of the reinforcing member 16, and the distance of the winding loops on the peripheral surface 22 is exactly the same viewed over the circumference of the later tire.
  • the impact between the ends of the reinforcing members preferably comes to lie in the central region 20, so that he later can be cut away and the uniformity of the extent of the later individual strength member 16 can not affect.
  • the winding of the reinforcing member 16 is preferably generated via a revolving robot arm of a winding device, which is not shown in the figures.
  • the building drum 12 is mounted on a drive shaft, which is apparent from Fig. 3 and will be described in the sequence.
  • Fig. 2 From Fig. 2 it can be seen, in which way the strength members 16 extend. The extension is viewed in the radial direction over the free side 18. From Fig. 2 is a circular cutout 30 can be seen, which cuts away the central region 20 of FIG. It is already here a bead core 32 launched, which closes the rim 34 of the tire rim side, as it is known. A projection 36 of the reinforcement 16 over the bead 32 is selected so that it is readily possible for the reinforcement 36-together with the inner liner 14-to be folded over the bead core 32 back to the outside.
  • Fig. 3 From Fig. 3 it can be seen in which way the building drum 12 is mounted on a drive shaft 38.
  • the drive shaft 38 extends on one side away from the building drum 12. It is attached to the central region 20 opposite region on the drive shaft side 24 of the building drum 12 and rotatably connected thereto.
  • the drive shaft 38 extends there over the radial center, which is thus not free for the winding process, in contrast to the free side 18th
  • deflecting pins 40 are mounted just next to the drive shaft 38, in a number which corresponds to the number of winding loops of the reinforcement 16.
  • Each winding loop of the reinforcing member 16 is now guided by a deflection pin 40, and guided around from there to the drive shaft 38 and then continued to the opposite guide pin 40 and deflected there again, so that nevertheless an exactly radial course of the reinforcement - at least outside the central region 20, which is cut out anyway later - is feasible.
  • the reinforcing elements 16 can also extend obliquely in the region of the running surface 22.
  • This strength carrier image can easily be Produce by the fact that the building drum 12 during the winding process on the tread 22 is simply further rotated a little more.
  • Fig. 5 shows a crossing of the reinforcement 16 in the tread area.
  • two strength members are applied without further ado, during application of the first reinforcement, the building drum 12 is rotated in one direction, and the application of the second strength member 16, the building drum 129 is rotated in the opposite direction.

Abstract

L'invention concerne un dispositif de montage de pneu (10) doté d'un tambour de montage (12) pour l'application d'un revêtement intérieur (14) sur celui-ci et d'un dispositif d'enroulement pour des supports de résistance (16), le tambour de montage étant monté sur un arbre d'entraînement (38) uniquement sur l'un de ses côtés, le côté d'arbre d'entraînement. Le dispositif d'enroulement enroule le support de résistance sur le revêtement intérieur dans la forme finale existante, y compris lors de l'achèvement du pneu. Le dispositif d'enroulement autour des supports de résistance sur le côté libre opposé à l'arbre d'entraînement effectue un enroulement transversal au-dessus du tambour d'enroulement et sur le côté d'arbre d'entraînement en passant devant l'arbre d'entraînement sensiblement radialement.
