摘要： An apparatus for fabricating a perforated web comprises an endless masking plate (4) arranged above a continuously conveyed web (5). The masking plate has a plurality of apertures (34) arranged in a predetermined pattern, the masking plate being adapted so as to be continuously circulated. The light is irradiated to the web via the masking plate so that apertures or slits are formed in the web corresponding to the apertures of the masking plate. The light source (1) may be a laser, an infrared light, or an ultraviolet light, and the light from the source is diverged transversely about the web and converged longitudinally about the web.
