Abstract
The roller bar chains of a continuous press for producing pressed board provided sufficient play for the roller bars relative to the link chains by having the journaling pins for the link chains extending through bushings which articulate the overlapping link plates together, so that the outer diameters of the pins within these bushings are less than the inner diameters of the bushings. The result is that the roller bar chain has only a single guide plane in the press region between the two press plates.
Claims9
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 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 said bushings.
