Mixing and plasticating machine (100) for continuous conditioning processes, comprising: a housing (10) in which a hollow interior (18) is formed that is delimited by the interior peripheral surface of the housing (10) and extends in the longitudinal direction of the mixing and plasticating machine (100); a screw shaft (12) which extends through the interior (18) of the housing (10), rotates in the interior (18) of the housing (10) during operation and simultaneously moves translationally back and forth; a drive which rotates the screw shaft (12) during operation; and a filling device (36) arranged on the housing (10), for feeding at least one starting material into the interior (18) of the housing (10), the filling device (36) extending through a cut-out (42) that extends through the housing wall (40) or being connected to a cut-out (42) that extends through the housing wall (40), the filling device (36) comprising at least two cavities (54, 54) that each extend over the height of the filling device (36), which cavities are separated from one another by at least one separating wall (52, 52).

A method and apparatus for a reciprocating kneader. A primary rotational gear is attached to a gear box primary shaft and rotates in concert therewith and engages a secondary rotational gear. The primary rotational gear drive provides a primary source of rotation for a kneading screw and for the secondary gear as a secondary source of rotation. An adjustable eccentric is coupled to the secondary oscillation gear and rotates in concert therewith for reciprocation motion.

A gear box for a reciprocating kneader. A primary rotational gear is attached to a gear box primary shaft and rotates in concert therewith. A secondary rotational gear is engaged with the primary rotation gear and rotates therewith. A secondary shaft is attached to the secondary rotational gear and rotates therewith. A primary oscillation gear is attached to the gear box primary shaft and rotates therewith. A secondary oscillation gear is rotationally engaged with the primary oscillation gear and rotates on the secondary shaft. An eccentric is coupled to the secondary oscillation gear and rotates in concert therewith. A yoke is engaged with the eccentric and oscillates on an axis perpendicular to the secondary shaft in response to the lobe. The gearbox secondary shaft moves along its axis in concert with yoke oscillation. A housing is pivotally attached to the yoke and pivotally attached to a casing at a casing.
