ABSTRACT:
A method for the manufacture of man-made fish-gathering plates having specific gravity between about 1.2 to 1.8 comprising the steps of providing a charge of raw material consisting of subdivided composite plastic consisting of at least two types of thermofusible plastic material or at least one type of thermofusible plastic material and non-plastic material, forming a molten mass from said charge of raw material by mixing by an agitator said charge with particulate inorganic material so the molten mass contains 25 to 70 weight percent of thermofusible plastic material as a bonding agent, said inorganic material being preheated to a temperature suitable for melting the thermofusible plastic material as a bonding agent and said agitator being kept at substantially the same temperature, charging the molten mass into a mold in a press machine to form it into a shape conforming to the shape of the mold, and after cooling solidifying the resulting shaped article, removing it from the mold.
