The compression molding of sections, bars, molded articles, or similar, consisting of vegetable particles mixed with binding media was uneconomical, because the relatively short molding time was overlapped by the disproportionate curing time. In order to considerably improve upon this deficiency, the inventor proposes to feed the molded section, or similar, along its longitudinal axis into a curing unit, while the sections between the molding jaws should remain in clamped position. The molding jaws, together with the cured section, are then returned through the press and the section is ejected after the unlocking of the molding jaws. Within the framework of the cyclic work, the individual operating processes can be adjusted to one another.

An apparatus for the compression molding of an elongate body from particles of vegetable matter and a thermally curable binder, said apparatus comprising: means for metering a mixture of said particles and said binder into a chamber to form an elongate blank; a first plurality of molding jaws at a pressing station for subjecting said blank to compression between them, said first plurality of molding jaws engaging said elongate blank over its entire length and completely enclosing the periphery of said blank to impart a final shape to said blank conforming to the intended shape of the compression-molded body; means for transferring the first plurality of molding jaws and the blank compressed thereby as a unit and without relaxation of compression force to a curing station at a location spaced from the location of said pressing station so that another blank can be subjected at said pressing station to compression by another plurality of molding jaws advanced to said pressing station; means for curing the blank at said curing station within the confines of said first plurality of molding jaws and under the pressing forces thereof to transform said blank at said curing station to a corresponding compression-molded body; and means for separating the molding jaws of said first plurality to release the compression-molded body transformed from said blank.
