Abstract

"DISPOSITIVO DE EXTRUSãO PARA FABRICAR UM PRODUTO à BASE DE UMA MISTURA BORRACHOSA, E, APARELHAGEM DE EXTRUSãO DE VáRIAS MISTURAS BORRACHOSAS". A invenção se refere a um dispositivo de extrusão (1) para fabricar um produto à base de uma mistura borrachosa, que compreende um rolo rotativo (5), um orifício de entrada (15) da dita mistura borrachosa e uma abóbada (6) que recobre circunferencialmente parcialmente a superfície (51) do rolo (5), a mistura borrachosa sendo empurrada a partir do orifício de entrada (15) no entreferro situado entre a abóbada (6) e o rolo (5) na direção de um orifício de extrusão (21) que define o perfil do produto, delimitado por uma parede (20) que opera junto com a superfície exterior (51) do rolo (5), a abóbada (6) leva em sua superfície interior orientada na direção do rolo filetes salientes a fim de delimitar com a superficie (51) do rolo uma câmara de plastificação da mistura, pelo menos dois dos filetes se estendendo sensivelmente axialmente.
