Abstract
A blower for discharging a gaseous flow to attenuate molten mineral material into mineral fibers comprises a body member and a cantilevered lid member mounted on the body member to define a gas supply manifold and a gas discharge slot. The free end of the lid member is biased toward the body member and a jackscrew is adapted to raise the free end of the lid member from the body member to adjust the slot width.
