Abstract

bandas de rodagem de pneus e um método para formar bandas de rodagem (10) de pneus tendo uma lamela (9) com um comprimento se estendendo entre extremidades terminais opostas da lamela e tendo uma altura e uma espessura que são variáveis através do comprimento e da altura da lamela. a espessura da lamela (18) inclui uma porção de lamela disposta entre as extremidades terminais opostas definindo o comprimento da lamela e tendo uma porção espessa se estendendo pelo menos parcialmente em torno de um perímetro de uma porção fina. a porção fina é substancialmente de 0,2 milímetro ou menos de espessura e forma pelo menos 40% da área de superfície ao longo de lados opostos da lamela, os lados opostos são dispostos em lados opostos da espessura de lamela.
