Pre-press and system for the continuous production of material plates, method for introducing or removing the press belt and transport device for receiving the press belt

摘要

The present invention relates to a pre-press (10) for the continuous production of material plates, comprising: at least one endlessly circulating upper press belt (12) and a lower press belt (14) for conveying a spreading material mat (60) through a press nip (16) between the press belts ( 12, 14); a plurality of lifting elements (18a, 18b) for exerting a pressing force on the spreading material mat (60), wherein a first lifting element (18a) and a second lifting element (18b) are preferably arranged oppositely on both sides of the press nip (16); wherein on a side remote from the second lifting element (18b) side of the first lifting element (18a) on the upper strand (20) and lower strand (22) each have a lever extension (28) for coupling a tension element (30) for receiving a between the two lever extensions (28) is seconded acting pulling force; and the second lifting element (18b) is releasably connected to the pre-press (10) such that in the released state the press nip (16) on the side of the second lifting element (18b) is accessible and the press belt (12, 14) is completely removable. The present invention further relates to a method for removing an endless press belt (12, 14) from a pre-press (10) and a transport device (34) for receiving a removed endless press belt (12, 14) of a pre-press (10) and a system (32 ) for the continuous production of material plates.
