is associated with high assembly costs and machine downtimes, because the telescopic cover boxes need to be disassembled. In other known designs, the replacement of the damaged wiper lips only possible with special tools.

Therefore, the innovation is based on the task while avoiding the aforementioned difficulties and

This task is solved according to the innovation as follows: In the drawing, FIG. 1 shows the stripping device. This consists of a protective strip 1 made of spring steel, an anchor rail 2 made of steel and a wiper lip 3, which depending on the operational requirements consists of more or less elastic material.

The protective strip 1 and the anchor rail 2 are inextricably linked to form a unit, and form the receiving strip ha

The receiving bar 4 is with your rear Leg 4a attached to the front edge of the cover box 5. The connection can be made in a known manner This is done by screwing, riveting, welding or gluing.

As can be seen from the drawing Figure 2, the wiper lip 3 is depending on the operational situation either swiveled into the mounting strip 4 from untön or, as FIG. 3 shows, pushed into the receiving strip 4 from the side.

The profile of the wiper lip 3 is dimensioned so that it extends over the anchor rail according to FIG. 2 from below 2, taking advantage of the elasticity of the lip material, into the resilient protective strip 1 can swing in.
