摘要

The invention relates to a device for cleaning a roller (1) of a system for machining a strip-type material, comprising at least one jet nozzle (5), which directs a fluid stream onto the surface (2) of the roller (1), and at least one suction channel (8). The at least one jet nozzle (5) and the at least one suction channel (8) are arranged in a hood (4), and the hood (4) covers part of the circumference of the roller (1). The at least one jet nozzle (5) is arranged at an angle of +/- 45° relative to the vertical on the surface (2) of the roller (1) and at a distance of less than 50 mm from the surface (2) of the roller (1).
