Method of molding a foamed mattress having a crown area with cored-out areas

摘要

A process for casting a foamed mattress having a crown area with cored-out areas therein to modify the harshness of feel of said mattress. A mold cavity having gates therein to give the cored-out pattern in the crown of the mattress is provided and a liquid foamable urethane resin reaction mixture is deposited and distributed in a fan-shaped arc in the cavity from preferably two or more distributing beads in response to the relative movement of the depositing and distributing means to that of the mold. The deposited mixture is then permitted to foam in order to fill the mold and to their cure prior to removing the product from the mold cavity.
