Abstract:

An apparatus and method wherein strips of elastomeric material are fed separately onto a roller at more than one position around the circumference of the roller at predetermined axial locations to form predetermined cross-sectional areas of the cross section of the band. Between the positions where the strips are applied and prior to removing the band from the roller, guide means is provided to guide the strips in the predetermined axial locations. The guide means confines the strips between a circumferentially grooved guide member and the cylindrical surface and the grooved guide member may be a replaceable insert mounted in a recess of a plate for accommodating different sizes and shapes of the formed band with different inserts.

Abstract:

A method and apparatus for controlling the discharge of an elastomeric material from a high intensity mixing machine having a mixing chamber with two rotors and an outlet with a drop door. The drop door is open when the rotors are in a predetermined preferred position for unloading the mixing machine in response to the positions of indicators on the rotor shafts. Sensors mounted in the wall of the outlet determine when the gate is clear after unloading of the mixed elastomeric material whereby the drop door may be moved into the outlet for closing of the mixing chamber as soon as the unloading is completed.
