An apparatus () for correcting the bending of the molten resin includes a temperature-adjusting device () arranged surrounding an extrusion passage () for extruding the molten resin () of an extrusion die head () along the direction of extruding the molten resin (), a measuring means () for measuring the horizontal position of the molten resin () extruded from an extrusion opening () of the extrusion passage (), and a control means () for controlling the temperature-adjusting device () based on the results measured by the measuring means ().

Apparatus for correcting the bending of a molten resin and method of correcting the bending of the molten resin

A compression-forming system comprising a molten resin mass-feeding device equipped with the holding portions for holding the molten resin masses, a compression-forming machine equipped with the metal molds, and a molten resin mass position detector, wherein said molten resin mass position detector is a temperature sensor, and said temperature sensor measures the temperature of a portion on the outer side of an allowable range in which the molten resin masses are fed to the metal molds, and judges the presence of the molten resin masses on said portion by the temperature of said portion of the metal molds to detect that the molten resin masses are defectively handed over.

Compression-forming system

An apparatus for feeding a molten resin is operated for extended periods of time maintaining stability without permitting volatile components of the molten resin to adhere on the surfaces of conveyer means. An extruder in the apparatus for feeding the molten resin to the compression-forming machine has an extrusion unit which discharges a molten resin through an extrusion opening of an extrusion nozzle. An air injection nozzle for injecting the cooling gas is provided along the outer circumference of the extrusion nozzle, and the cooling gas is blown onto the surface of the molten resin extruded from the extrusion opening to cool the surface of the molten resin.
