ABSTRACT:
A machine for forming blocks of fibrous insulation from a continuous fibrous blanket. These folded blocks may be used in furnace linings or the like. A pair of oscillating folder vanes form folds which extend in alternating directions. The vanes are oscillated by a continuously driven motor through a crank linkage. A reciprocating support vane engages the newly formed folds and supports them while the folder vanes are being disengaged from the blanket. A feeder drum and bearing member co-act to form a material supply loop from which the folds are made. The same motor drives all moving parts making the controls simple and inexpensive.
