Abstract

"PROCESSOS PARA PRODUZIR UMA BANDA DE RODAGEM DE PNEUMáTICO DE CAMINHãO INTEIRA E PARA PRODUZIR UM MOLDE PARA UMA BANDA DE RODAGEM DE PNEUMáTICO, MOLDE DE BANDA DE RODAGEM DE PNEUMáTICO, E, BANDA DE RODAGEM DE PNEUMáTICO". A presente invenção é um processo para produzir uma banda de rodagem de pneumático de caminhão inteira, compreendendo as etapas de prender segmentos de molde de banda de rodagem compreendendo placas em um suporte plano, colocar uma banda de rodagem em bruto sobre os segmentos de molde, e prensar a banda de rodagem em bruto contra os segmentos de molde. A invenção também compreende este processo em que segmentos de molde de banda de rodagem compreendendo placas são formados pelas etapas de usinar pelo menos um lado de uma placa de modo que a variação de pico a pico da superfície de placa seja menor do que 5 mícrons, prender as placas em um suporte plano; e usinar um padrão de banda de rodagem reverso sobre as placas presas. A presente invenção também compreende um processo para produzir um molde para uma banda de rodagem de pneumático compreendendo as etapas de prender segmentos de molde de banda de rodagem compreendendo placas de pelo menos duas diferentes espessuras em um suporte plano, e usinar um padrão de banda de rodagem reverso compreendendo cristas sobre as placas presas, onde a espessura da placa sob a crista é escolhida de modo que a relação entre largura e altura de uma crista em uma placa não é menor do que 1:10."PROCESSES TO PRODUCE A FULL TRUCK TIRE TRACKING AND TO PRODUCE A TEMPLATE FOR A TIRE TRACKING TEMPLATE, AND, TIRE TRACKING TRAY". The present invention is a process for producing an entire truck tire tread comprising the steps of securing tread mold segments comprising plates on a flat support, placing a raw tread on the mold segments, and pressing the raw tread against the mold segments. The invention also encompasses this process wherein tread mold segments comprising plates are formed by the steps of machining at least one side of a plate such that the peak to peak variation of the plate surface is less than 5 microns, attach the plates to a flat support; and machining a reverse tread pattern over the stuck plates. The present invention also comprises a process for producing a tire tread mold comprising the steps of securing tread mold segments comprising plates of at least two different thicknesses on a flat support, and machining a tread pattern. reverse running comprising ridges on the attached plates, where the thickness of the plate under the crest is chosen such that the ratio of width to height of a crest on a plate is not less than 1:10.
