ABSTRACT:
A machine for working the butt weld seam of a band belt, preferably having a toothed edge, includes various stations disposed successively along a feed path. The stations are a milling device, a grinding device, two ridge milling devices and a band advance device. In the milling device the welding beads are milled off on both broad sides of the band belt to form flat bases which are subsequently surface-ground in the grinding device. The succeeding milling device removes the ridge on the back of the band belt and the other milling device removes the ridge in the toothed space. The milling device for the toothed edge comprises a sensing element which is guided along a tooth of a template corresponding to the tooth space contour or another tooth space of the same band belt. The machine operates automatically under program control and achieves, without impairment of the welding seam, clean-right-angled plane faces, accurate to the required dimensions on the band belt, as well as a removal of the ridges on the narrow faces of the band belt, without damaging the saw tooth.
