ABSTRACT:
Apparatus for strapping articles, wherein the band channel (28) of the band guiding frame (13) is covered by profile strips, which consist of an elastic material, preferably an elastically curing polyurethane elastomer casting mass, into which are embedded wear and/or sliding elements in the form of metal helical spring elements (34), the helical spring axes of which run essentially parallel to the band channel (28), and the coils of which project a little bit from the elastic material into the interior (28) of the band channel and form curved sliding surfaces (35) running essentially transversely to the band channel, so that the strapping band essentially only comes into contact with the metallic sliding surfaces of the spring elements during the exit from the band channel, and thereby does not damage the elastic material of the profile strips.
