The device of this invention cuts multiple extrudates to a constant length while at the same time preventing any bending and resulting weakening of the extrudates. These extrusions are cut by a gaseous pressure source by directing this gaseous pressure in the area of the extruder die face. When the extrusion is of a preprogrammed length, the gaseous force on the extrudate will be sufficient to shear the material at the die face. An essentially opposing gaseous pressure force may be used in conjunction with the basic gaseous shearing structure. Inorganic extrudates are very effectively sheared using this device. |
