the end liners 340 and 345 stay in place during the vibration step as illustrated in fig4 e molded product 350 may remain on the pallet p as the demolding process occurs the separation of mold assembly a and pallet p may continue until all of the molded products 350 in mold assembly a are clear of the end liners 340 and 345 in one exemplary embodiment of the present invention the entire process of forming and demolding a tapered block may occur in approximately fourteen seconds however this period may be shorter or longer depending on the type of machinery and materials used to manufacture the blocks or the type of blocks being manufactured the apparatus and method of the present invention thus permit simple automatic demolding of high quality tapered molded products by separating the mold assembly a and the pallet p on which the products 350 are formed and supported the apparatus is simple in construction and in at least one embodiment does not require any external power or control devices to effect movement of the end liners 340 and 345 while the above discussion relates to molded products having two tapered edges it is contemplated that the apparatus and method of the present invention may be utilized for forming asymmetrical molded products for example a mold cavity 26 may be configured to have only one movable end liner and three fixed mold walls to form an object having only one negatively tapered side alternatively a molded product having more than two negatively tapered sides may be produced by utilizing a mold cavity 26 having more than two movable end liners furthermore while the movement of the end liners 340 and 345.
