Abstract
A fiber block molding apparatus comprising: —a mold having a lower part and an upper part forming between them a cavity for forming a fiber blank into a fiber block article upon closing the mold; —a conveyor system for receiving the fiber blank to be molded at a receiving position, transporting the fiber blank via a heater for activation of a binding agent, and delivering the heated fiber blank into the lower part of the mold at a delivery end of the conveyor system, and —a horizontal position shifting arrangement for shifting the horizontal position of the delivery end of the conveyor system relative to the lower part of the mold between a first and a second position to lay the fiber blank on the lower part of the mold.
