  • Patent number: 4054632
    Abstract: An improved method for handling of materials having characteristics such that they are normally solid at room ambient temperatures and are prepared and used at elevated temperatures to transfer the form of the material to a liquid. The improved method provides for handling of the material in liquid form and extruding it as a stream or continuous flow, cooling the outer surface of the same to solidify it and severing the stream of material with the hardened exterior and liquid interior such that the individual segments severed therefrom seal themselves and form individual pillow-like segments which can be then further cooled to a hardened state and readily handled, packaged, shipped and used.
