Abstract

"PROCESSOS PARA FORMAR UMA PLACA DE TELA, PARA FORMAR UMA TELA CILìNDRICA, PARA FORMAR UM CILINDRO DE TELA PARA PENEIRAR MATéRIA PRIMA DE FABRICAçãO DE PAPEL, E, CILINDRO DE TELA PARA PENEIRAR MATéRIA PRIMA DE FABRICAçãO DE PAPEL" Cilindro de tela (10) e processo e fabricar o mesmo são apresentados, no qual os desejados contornos laterais de entrada (29) e de saída (31) da tela são formados nos respectivos lados de uma placa de metal precursora (40), ou similar. Os contornos podem compreender uma série e ranhuras (46) formadas ao longo dos respectivos lados de topo (42) e de fundo (44) da placa (40). As ranhuras (46) não se estendem através da placa (40) mas ficam em substancial superposição uma com a outra, de um lado da placa para o outro. A placa (40) é formada na forma desejada e os entalhes (62) cortados na placa (40) para efetuar comunicação entre os contornos de entrada e de saída, com os entalhes (62) funcionando como meio filtrante"PROCESSES FOR FORMING A SCREEN PLATE, FOR FORMING A CYLINDER SCREEN, FOR FORMING A SCREEN CYLINDER FOR SCREENING PAPER MANUFACTURING MATERIAL, AND, SCREEN CYLINDER FOR SCREENING RAW MATERIAL FOR PAPER MANUFACTURING PAPER (10" cylinder) and method and manufacture thereof are presented, in which the desired lateral inlet (29) and exit (31) lateral contours of the screen are formed on the respective sides of a precursor metal plate (40), or similar. The contours may comprise a series and grooves (46) formed along the respective top (42) and bottom (44) sides of the plate (40). The grooves (46) do not extend across the plate (40) but are in substantial overlap with each other, from one side of the plate to the other. The plate (40) is formed in the desired shape and the notches (62) cut in the plate (40) to make communication between the entrance and exit contours, with the notches (62) acting as a filter medium
