A continuously operable belt-type press comprises two endless upper and lower press belts forming a pressing gap in a pressing region, an upper and lower platen, a drive mechanism and a press framework. In the pressing region two rod containers are positioned from which a plurality of rolling rods are fed with spacing from each other, these rolling rods being guided above the upper press belt and below the lower press belt by rod circulating mechanisms each comprising two synchronized first chains each guided over at least one sprocket and first chain drive wheel. In the entrance region of the pressing gap and of the upper and lower platens second chains are positioned over a second chain guide wheel. On the chain rollers of the second chains rolling rods are guided between the first chains and act similar to roller bearings. The first chains and second chains in the entrance region form an entrance V-shaped region symmetrical with respect to a horizontal center plane, in which the press belts press the rolling rods on the chain rollers of the second chain formed with equalizing free play. These second chains act as aligning means for the input of rolling rods perpendicular to the circulating direction. The sprockets and the second chain guide wheels at the entrance end of the press are positioned on a common guide wheel shaft, which is driven rotatably. The guide wheel shaft is at least at a first end supported in a sliding carriage, which by an adjusting motor is shiftable in a horizontal direction. |
