Abstract

See full text

In the arrangement, a feed beam made of an aluminum profile comprises a slide guide frame, whereby the outer surface of the slide guide frame and respectively, the inner surface of the slide guide are shaped and dimensioned in such a manner that when the slide guide is on the slide guide frame, they are tight against one another. The other edge of the slide guide flame and respectively, the corresponding edge of the slide guide are shaped in such a manner that when the slide guide is mounted in place, its edge is shape-locked relative to the slide guide frame. The slide guide is also secured by separate securing mechanism to the feed beam in such a manner that it cannot move either in the cross or longitudinal direction relative to the feed beam.
