<p>The lever spreads across the join between the two mould halves to engage in a mounting on one half-mould and is attached to a piston on the other half-mould, with a flanged surface engaging a matching angled support. The operation of the piston on the lever forces the mould apart, overcoming initial resistance and adhesion between foam component and mould interior, the angled surface increasing the opening action and disengaging the lever.</p> |
