Abstract

PURPOSE: To prevent cohesion of chip-like polyester molding material in drying, by forming a specific depression on the naturally cooling surface of the material.
CONSTITUTION: At least one dimple-like depression is formed on the naturally cooling surface of a chip-like polyester molding material consisting mainly of a repeating unit of an alkylene terephthalate to produce the polyester molding material which will not easily cause cohesion in drying. The polyester is melt extruded from a nozzle of elliptical, oblong, or rectangular cross-section satisfying the formula (a is the major axis or the long side; b is the minor axis or the short side) to produce a bar material, which is cut to a given length before their surfaces are solidified completely to give the desived molding material.
