ABSTRACT:
A foamed article having zones of varying hardness is prepared by moving a shaping means relative to at least two foam pouring means to distribute a foamable mixture over the surface of the shaping means in a fan-shaped pattern in response to the relative motion between the pouring means and the shaper, adjusting the fan-shaped pattern to define zones in the foamed article having the desired physical characteristics.
