description método para formar artigo de borracha estratificada com taxa de cura variável. a presente invenção refere-se a um método para formar uma banda de rodagem que compreende duas ou mais camadas de borracha. o método inclui as etapas de: extrudar um composto de borracha através de um extrusor e uma bomba de engrenagem e misturar com um acelerante e, então, aplicar uma tira contínua de borracha diretamente sobre uma máquina de formação de pneu para formar uma primeira camada de borracha que tem uma primeira taxa de cura; ajustar a quantidade de acelerante para obter uma segunda taxa de cura diferente da dita primeira taxa de cura e, então, aplicar uma tira de borracha que tem uma segunda taxa de cura sobre a máquina de formação de pneu, sendo que uma das taxas de cura é mais rápida que a outra taxa de cura. A method of forming a rubber article (200, 300) comprising two or more layers (220, 230) of rubber is disclosed. The method comprises the steps of extruding a first rubber compound (A) through a first extruder (20) and a first gear pump and mixing a first mixture comprising the first rubber compound (A) and an accelerant, the first mixture having a first cure rate; applying one or more first strips of rubber of the first mixture directly onto a substrate, a tire building machine, a tire building drum or a tire mandrel; adjusting the amount of accelerant and/or using an other accelerant; mixing a second mixture comprising the first rubber compound (A) and the accelerant and/or the other accelerant, the second mixture having a second cure rate different from the first cure rate; and applying one or more second strips of rubber of the second mixture. Also an apparatus (10) for manufacturing a rubber article (200, 300) is disclosed.
