Patent ID: 7096778

Claim:
A continuous press for producing pressed board comprising: an upper and a lower press plate; respective endless steel belts passing between said press plates and entraining a layer of material therebetween capable of being compressed to form pressed board; respective roller bar chains displaceable around said upper and lower press plates whereby roller bars of said chains are interposed between said belts and the respective press plates, each of said roller bar chains comprising: a respective roller bar journaling pin engaged in each end of a respective roller bar, and a link chain at opposite ends of the respective roller bars and receiving said pins with play in a direction of travel of the respective chain to entrain said roller bars with said chains, each link chain comprising two rows of outer link plates, two rows of inner link plates overlapped with said outer link plates and link connecting bushings articulating overlapping inner and outer link plates together and traversing the overlapping inner and outer link plates, said roller bar journaling pins traversing said bushings and being received with play in a longitudinal direction of said pins in said bushings at both ends of each bushing; wherein at least in regions of the link connecting bushings the outer diameters of said roller bar journaling pins are less than the inner diameters of said bushings to provide said play in said direction of travel for said roller bar journaling pins in said bushings, and wherein said pins have diameters at least equal to said inner diameters outside said regions.
