Abstract

"PROCESSO DE FABRICAçãO DE UMA LAGARTA E DISPOSITIVO DE DESMOLDAGEM". Processo de fabricação de uma lagarta constituída de uma cinta contínua no sentido circunferencial em material elastomérico e compreendendo uma estrutura interior e uma superfície exterior, sendo que a superfície interior é dotada com uma pluralidade de dentes de tração distribuídos regularmente no sentido circunferencial, sendo que o processo compreende uma etapa de acordo com a qual se monta um molde interno (10) formado pelas primeiras e segunda meias-formas (11, 12), sendo que as referidas duas meias-formas podem ser deslocadas uma em relação à outra no sentido axial para entrar em contato uma sobre a outra em uma superfície de junção. O molde interno (10) compreende uma superfície de aplicação (100) radialmente voltada para o exterior dotada com uma pluralidade de cavidades (103) espaçadas regularmente para a moldagem dos dentes de tração, sendo que cada cavidade é delimitada no sentido axial por duas paredes laterais (111, 121), sendo que a superfície de junção (13) das duas meias-formas (11, 12) encontra-se axialmente mais próxima de uma parede lateral do que da outra parede lateral.
