Abstract

ELEMENTO DE FILTRO COM MEIO DE FILTRO DOBRADO EM ZIGUE-ZAGUE COM LIGAÇÃO DA BORDA FRONTAL DESCONTÍNUA ASSIM COMO PROCESSO PARA A PRODUÇÃO DE TAL. A presente invenção refere-se a um elemento de filtro (10) para filtrar um fluido, particularmente ar, com um corpo de filtro (14) com um meio de filtro dobrado em zigue-zague (18), cujas dobras (20) se estendem em um sentido de dobra (22) e que é previsto para a vedação de suas extremidades de dobra com uma ligação da borda frontal (50), que é concretizada de forma descontínua na área de pelo menos um retorno (38) do contorno externo (36) do corpo de filtro (14) e apresenta pelo menos um primeiro segmento de ligação (52) disposto no lado externo, e compreende um segundo segmento de ligação (54) interno no sentido de dobra (22), em que, o segundo segmento de ligação (54), no sentido transversal ao sentido de dobra, é disposto afastado ao primeiro segmento de ligação (52) e em que ambos os segmentos de ligação (52, 54) colam pelo menos uma dobra comum (20). Além disso, a invenção se refere a um processo para a produção de um elemento de filtro (10) mencionado acima, que pode ser realizado de forma econômica com meios técnicos simples e que é particularmente adequado para a produção em massa de elementos de filtro (10).
