Abstract

"TUBO DE DESCARGA FORMADO EM ESPIRAL" Um método é fornecido para a produção de um tubo de descarga formado em espiral (12). O material (14) tendo primeira e segunda bordas separadas (50, 52) e uma matriz (86) tendo uma ranhura (96) são fornecidos. Frestas de ventilação (32) são formadas no material (14). O material (14) é enrolado em um tubo usando a matriz (86), de forma que as frestas de ventilação (32) estendem-se para fora para longe de um eixo longitudinal (84) do tubo (12). As frestas de ventilação (32) passam através da ranhura (96) da matriz (86) quando o material (14) é enrolado no tubo (12). As primeira e segunda bordas (50, 52) do material (14) são então conectadas."SPIRAL FORMED DISCHARGE TUBE" A method is provided for the production of a spiral shaped discharge tube (12). The material (14) having first and second separate edges (50, 52) and a matrix (86) having a groove (96) are provided. Ventilation slots (32) are formed in the material (14). The material (14) is rolled into a tube using the die (86), so that the ventilation slots (32) extend outwardly away from a longitudinal axis (84) of the tube (12). The ventilation slots (32) pass through the groove (96) of the die (86) when the material (14) is wound on the tube (12). The first and second edges (50, 52) of the material (14) are then connected.
