Abstract

"APARELHO E MéTODO DE RETENçãO DE ESTRUTURA PAPA LâMINA DE CORTE". Um aparelho e método de retenção de estrutura para proteger a borda de uma estrutura cortada contra o movimento ou empilhamento durante as operações subseq³entes na estrutura. A invenção preferivelmente utiliza uma abertura de vácuo que suga e mantém uma porção ( por exemplo, a borda ) de uma estrutura que foi cortada. A abertura de vácuo é conectada em um gerador de vácuo que cria uma força de sucção puxando a porção da estrutura para dentro e mantendo-a dentro da abertura de vácuo. Para essa finalidade, a abertura é preferivelmente uma ranhura ou fenda alongada localizada perto da posição na qual a estrutura está cortada, dessa maneira permitindo que a porção da estrutura estenda-se perto e seja puxada para dentro da abertura de vácuo. A abertura pode ter uma garganta definida por uma ou mais paredes que se estendem abaixo da superfície na qual a abertura está localizada. A presente invenção encontra aplicabilidade particular em um rolo de corte, onde uma ou mais lâminas de corte são montadas em uma superfície do rolo de corte. Em um tal sistema, a abertura de vácuo preferivelmente corre lado a lado e atrás da lâmina de corte e puxa ( via a sucção através da abertura de vácuo) a porção da estrutura cortada para dentro da abertura de vácuo depois que a estrutura foi cortada pela lâmina de corte. Em outras modalidades da invenção, a abertura de vácuo pode ficar localizada em frente da lâmina de corte para prender essa parte da estrutura cortada que situa-se em frente da lâmina de corte. De fato, uma abertura de vácuo pode ficar localizada em ambos os lados da lâmina de corte, se desejado.
