Abstract
The present invention relates to an apparatus and method for forming molded tapered products, such as masonry blocks, whereby high quality finished products are removed from their mold without the need for complex machinery for demolding. The mold may include one or more mold cavities having one or more movable cavity walls. The movable cavity walls may include an end liner having a planar product forming surface capable of moving from a vertical position to an angled position. Tapered products may be formed by moving the mold towards a pallet so that the pallet engages with the end liner and causes the end liner to move from the vertical position to the angled position. Moldable material may then be introduced into the mold cavity and may be allowed to remain in the mold cavity until it is self-sustaining.
