CENTER DECK ASSEMBLY FOR TIRE BUILDING DRUM

The invention is directed to a center deck assembly for a tire building drum. The tire building drum is rotatably mounted on a central drive shaft and includes a center section. The center deck assembly is disposed in the center section of the drum and includes a hub that seats on and is secured to the central drive shaft. At least one piston extends circumferentially in the tire building drum about the hub and a plurality of segment bars are disposed about the circumference of the center deck assembly. The at least one piston is operably connected to the segment bars by a plurality of linkages, in which each of the linkages includes a scissor-lever mechanism.

METHOD OF FORMING AN ELASTOMERIC STRIP
20180001536 · 2018-01-04 ·

A method for applying a strip of elastomeric material to a surface is described. The method of forming a strip of elastomeric material includes the steps of: pumping an elastomeric material through a nozzle, positioning an opening of a nozzle in mating engagement with a rotatable roller, rotating the roller so that rotation of the roller pulls the elastomer material through the outlet of the nozzle, forming a strip.

A pair of annular inserts of elastomeric material is circumferentially applied by spiraling around a laying surface of an auxiliary drum. Then a plurality of strip-like elements disposed in parallel side by side relationship with each other in the circumferential extension of the laying surface is applied onto the auxiliary drum, so as to form at least one first belt layer. Respectively opposite end portions of each strip-like element are radially superposed, each against one of the annular inserts, so that each of the annular inserts projects from a respective end edge of the strip-like element. The cap structure formed on the auxiliary drum is coupled to a carcass structure through toroidal conformation of the latter, in such a manner that the radially external ends of sidewall portions previously manufactured on the carcass plies are associated with the axially external ends of the annular inserts.

TIRE MEMBER-FORMING APPARATUS
20170165934 · 2017-06-15 · ·

The present invention glues a rubber strip on the surface of a non-right circular cylindrical winding body with good precision. The present invention reduces the space occupied by the apparatus. The tire member-forming apparatus is provided with a transport conveyor with a conveyor belt that is guided by guide rollers so that the conveyor belt is able to circle. The conveyor surface of the conveyor belt is provided with a conveyor surface width center line that extends in a straight line over the entire length thereof. The guide rollers are grouped into guide rollers on the front side of the conveyor direction and guide rollers on the back side of the conveyor direction. The front guide rollers are held so as to be capable of tilting around the conveyor surface width center line. As a result, on the conveyor surface, a twistable twisting conveyor surface section is formed between a front conveyor surface section, which is supported by the front guide rollers, and a back conveyor surface section, which is supported by the back guide rollers.

FOLLOW-UP CONTROL METHOD AND SYSTEM FOR FORMING MACHINE

Disclosed are a follow-up control method and follow-up control system for a forming machine. The follow-up control method comprises: responding to an instruction for a forming drum module to move from a fitting station to a locking ring station, controlling the forming drum module and the stitching and pressing roller module to move towards the ring locking station, in which the moving speed of the stitching and pressing roller module to the ring locking station has a pre-set speed difference from the moving speed of the forming drum module to the ring locking station, controlling a sewing pressure roller module to perform a sewing operation on a compound joint on a molding drum module, and when the molding drum module reaches a pre-set position before a loop locking position of the loop locking station, the sewing pressure roller module completes the sewing operation. The follow-up control method can enable a sewing operation of a sewing roller module to be performed at the same time as a loop-locking process of a shaping drum module, greatly shortening the action execution cycle in the whole control process of a shaping machine compared with a traditional step-by-step execution method.

Tire overlay composition

A tire comprising an overlay ply wherein (i) the shoulder section of the overlay comprises an elastomer and short polymeric or non-polymeric reinforcing fibers present in an amount of from 0.1 to 10 parts fiber per hundred parts of elastomer, the short fibers having a tenacity of at least 2 grams per dtex, a modulus of at least 10 grams per dtex and a length of from 0.1 to 8 mm and wherein the fibers are aligned substantially parallel to each other in a controlled angle of orientation within the overlay wherein the orientation is selected such that it decreases tire noise, and (ii) the section of overlay in the crown of the tire comprising cords of continuous filament polymeric fibers or continuous strands of metal or combinations thereof, the cords being aligned in a circumferential direction around the tire.
