Abstract
A bubble guide of the type employing guide members mounted on elongated, pivoted support arms. Rotation of the guide members, shown in the form of overlapping arcuate segments, results in dependent reverse rotation of the guides relative to the arms, produced by a compensating mechanism, for orientation purposes. Primary crank arms and connecting rods drive all support arms simultaneously and secondary crank arms and connecting rods produce simultaneous compensatory rotation of all guide members. Downward cantilevered mounting of sets of the guide members enables ready access from below and tilting of the sets enables variation in diameter along the assembly. Reaction of one or more guide members to change in the bubble size is employed to regulate cooling air flow into the extruding tube.
