ABSTRACT OF THE DISCLOSURE The apparatus for enveloping and packaging widely varying articles has a conveyor bet, to whose starting area are preferably supplied two foil webs, between which are located the articles to be packaged. Both between the articles and laterally, welds are produced by welding members, which are arranged on a three-dimensional frame, which can be moved up and down by means of a first crank drive (eccentric disk), in order to bring about the actual welding, which not only ensures the formation of a joint, but also constitutes a separation weld. The welding members are connected to the three- dimensional frame by a slide, which can be moved backwards and forwards in the feed direction and, in opposition to the feed direction of the conveyor belt on the frame, by a second crank drive (essentially) formed by a crank web, a link and a connecting rod). This ensures a synchronous movement of the welding members with the foils and articles, during the welding process. The two crank drives are jointly driven, the conveyor belt moves somewhat faster than the speed at which the foils are supplied, in order to further increase the separation of the individual packs produced by the separation weld. The apparatus operates continuously, i.e. without interruption, there being no stopping of the conveyor belt during welding. (Fig 1).
