Abstract

Patente de Invenção:<B>"PROCESSO DE DOBRAGEM PARA UM SACO DE GáS DE UMA INSTALAçãO DE AIRBAG"<D>. A invenção refere-se a um processo para a dobragem de um saco de gás conectado a um gerador de gás em uma instalação de airbag, em que ao menos uma parte da peça talhada de tecido estirada em plano, consistindo em duas camada de tecido encerrando o volume do saco de gás, é dobrada por meio de dobragem rolante, em que a peça talhada de tecido (11) estirada em plano é apanhada aproximadamente no meio de sua extensão por uma ferramenta (15) e enrolada na direção do gerador de gás (10), de modo que o segmento da peça talhada de tecido (11) posicionado sobre o lado da ferramenta (15) oposto ao gerador de gás (10), quando da rotação da ferramenta (15) na direção do gerador de gás (10) é de tal maneira retraído no rolo (16) que se forma, que resulta um rolo (16) de camada dupla do saco de gás dobrado, e que no final do processo de dobragem a ferramenta (15) é movida para fora do rolo (16).
