摘要
A method of manufacturing rigid frame building elements filled with hard foam plastic, said method comprising the use of prefabricated, rigid, dimensionally stable, hollow skeleton frames, the hollow interior spaces of said skeleton frames are foamed and filled with closed cell hard foam plastic serving as heat insulation, and the elements are subjected in a press to compression pressure which overrules the foaming pressured exerted on the frame of an element from inside. For continuous- action manufacture, the used press is a (known as such on the basis of size presses) continuous-action press machine whose lower frame is equipped with lower conveyor means (4) and upper frame with upper conveyor means (5), said conveyor means confining between themselves a conveying gap, in which the passing elements are maintained subjected to compression pressure by means of pressure members (7) carried by said conveyor means. The conveying gap, defined by said conveyor means and limited on at least one side by a horizontal tangential plane of parallel- disposed, crosswise of the machine extending rolls (5a), is set to be smaller than prefabricated skeleton frames. The prefabricated skeleton frames are fed into the conveying gap which due to the action of elements passing in said gap expands in a manner that each roll (5a) is capable of moving vertically against the force exerted by pressure members (7). Conveying speed is adjusted in view of the length of said conveying gap in a manner that expansion of a filling foam and the pressure generated thereby has substantially ceased by the time an element leaves the conveying gap.
