Abstract:
A gear extruder for the extrusion of a caoutchouc mixture or plastic granulate/materials, comprising:a housing having an entry opening and an interior wall in which a pair of driven gears, each with teeth and teeth spaces, that mesh with each other are housed, said extruder being equipped with an extrusion channel and two intake channels to which two separate intake feeding rollers are allotted, characterized by the fact that each intake roller with its roller surface is directly allotted and is arranged next to one of said gears for separately feeding the same, and that said intake rollers are arranged in separate recesses of said housing, each intake roller being ahead of a point at which the teeth of said respective gear runs along the interior wall of the housing, so that separate streams of material are fed to said extrusion channel, whereby said intake rollers force the extruded material to more completely fill and pack into the teeth spaces between said gear teeth to minimize inclusion of air and maximize material outflow from said gear extruder.
