A continuously operable belt-type press for making particleboard, fiberboard and the like pressedboard products comprises an endless upper press belt circulated over at least one upper belt guide roller, a corresponding endless lower press belt circulated over at least one lower belt guide roller, these press belts forming a pressing gap in a pressing region, and a press framework having a lower and upper platen as well as a drive mechanism. The rod circulating mechanisms each comprise two first chains each guided over at least one sprocket and at least one first chain drive wheel with support bolts for connection of the rolling rods, chain link members with chain bolts therein, outer running rollers mounted on the chain bolts, and guide rails for the running rollers. In the entrance region of the pressing gap and of the upper and lower platens correspondingly two second chains comprising a plurality of chain rollers in triangular configuration are positioned each guided over at least one second chain guide wheel. The chain link members are provided with rolling rod holders on their ends furthest from the guide rails, in the pressing region their ends closest to the press belt, which allow an equalizing free play for the rolling rods. |
