Abstract: A method and apparatus for producing die-cut brick is disclosed. The apparatus includes a cutter box in combination with a pusher which pushes elongated green clay slugs through the box. The box operates to cut a core extending lengthwise of the slug having the cross section of the desired brick. Guide means retain scrap completely around the core as it emerges from the die box and is moved in a stepwise fashion by the pusher to a cutoff device which cuts brick slices from the core. Because scrap is retained around the core, little or no distortion occurs during such slicing operation. The apparatus is arranged for quick and easy conversion from one shape to another.

Abstract: Method and apparatus for shaping of mats composed of loose fibers with a thermosetting resin interspersed throughout. The apparatus compresses the mat and exposes its laterally extending surfaces to elevated temperatures to obtain partial curing thereof. Slits are made in the surface regions adjacent areas where extra shaping will occur in forming the final product. These slits enable more precise shapes to be impressed upon the mat and eliminate the tendency of the partially cured areas to spring back to a position of lesser compression.

Abstract: Uniform pellets of thermoplastic material are formed by centrifugally expressing strands of heated material from orifices on the rim of a hollow rotor and severing the strands with a linearly moving endless blade at a selected radial distance from the rim.
