Abstract
PURPOSE: To prevent the occurrence of shock noise of windscreens by spot-welding the contact parts of a coarse-meshed wire gauze and a fine-meshed wire gauze in producing double wire gauzes for the windscreen of microphones.
CONSTITUTION: A coarse-meshed wire gauze 5 and a fine-meshed wire gauze 6 are let off from rolls 3, 4, and are passed through levelers 7, 8, whereby they are flattened. Next, both wire gauzes 5, 6 are superposed and are passed through electrode rollers 9, 10 and are pressure-welded by pressure-welding force; at the same time, electric power is supplied from the rollers 9, 10 to the contact parts 13 of both wire gauzes to spot weld the contact parts 13. The thus formed double wire gauzes 12 are passed through pressure type levelers 11 then through a pressing machine, whereby the windscreen for microphones is produced. Since the fine-meshed wire gauze 6 does not make contacting and spacing motion with respect to the coarse- meshed wire gauze 5 on account of wind pressure or shock, the occurrence of shock noise is prevented.
