ABSTRACT:
A scraper device for a paper machine comprises first and second scraper means that can be pivoted into engagement with a fabric web and with a guide roll, respectively. By combining at least two scraper means in a common assembly, a particularly compact and cost-saving structure is achieved. Due to the fact that the first scraper means is arranged upstream of the guide roll, viewed in the direction of travel of the fabric web, and that it can be pivoted into engagement with the fabric web from below in a manner such that a downwardly open space is left, it is guaranteed that the paper residues will be carried off completely even in case of trouble, for example in case of web failure.
