Used in conjunction with the unique 400 Series forehearth and one
of BH-F’s temperature control systems, the type 900 feeder can produce
unrivalled efficiency, from the furnace through to gob delivery.
This high-speed high-capacity feeder has helped to set
many new glass production records.
It has been used with the very latest high-speed and multi-gob I.S. machines.
A unique feature is the opposite-handed, ‘mirror-image’ version
which can allow shear angles round to 90^o right
previously unobtainable.
