Abstract

A device for manufacturing glass gobs includes a membrane body of a porous gas transmitting material. Channels for introducing compressed gas into the membrane body extend through the membrane body material and are spaced at a distance from the gas outlet surface of the membrane body. The channels run parallel to or are at an acute angle to the outlet surface. In an alternate embodiment, the channels are open channels at the opposite surface from the outlet surface.
