Abstract

"PROCESSO PARA FABRICAR UMA PLACA DE PENEIRA COM FENDAS DE PENEIRA, E, ELEMENTO DE PENEIRA". Um processo para fabricar uma placa de peneira com fendas de peneira a partir de uma placa fina (1) cujas fendas de peneira (5, 13), são conseguidas por meio de corte. A placa é formada por dobramento até uma placa de peneira de uma forma desejada. As fendas de peneira (5,13), são produzidas por meio de um feixe laser para corte, o qual atinge a placa a partir de um de seus lados, o lado de entrada. O foco para o feixe está situado sobre uma profundidade predeterminada entre ambos os lados da placa. A fenda é obtida por meio de no mínimo duas operações de corte, uma em seguida à outra, nas quais a direção (3, 4) do feixe laser forma dois diferentes ângulos com o plano principal da placa. Com isto, é obtida uma fenda de peneira (5,13) cuja seção transversal aumenta contra o outro lado da placa, o lado de saída.
