Mixing apparatus for pastes

A mixing apparatus for pastes, comprising

• a rotor mounted for rotation about a first axis,
• a mount having a longitudinal axis and adapted to receive a mixing container holding components of the paste, said container being generally cylindrical and elongate and having a longitudinal axis, the mount being supported on said rotor so as to be rotatable about a second axis eccentric with respect to the first axis,
• said mixing container including a piston disposed within said container at one end thereof for longitudinal movement to dispense paste from the container following mixing and removal of the container form the apparatus, said longitudinal axes of said mount and said container being substantially transverse to said first and second axes, and wherein the center of gravity of a unit constituted by said mount and said container inserted in the mount is disposed between said second axis and said piston irrespective of the position of the paste inside the container,
• transmission means for causing the mount to rotate about said second axis while the rotor rotates about the first axis, and
• means for switching said transmission means to a condition in which said mount is released so as to rotate freely about said second axis relative to the rotor.
