In a method or apparatus for wrapping a plurality of articles in metal foil, in which a sheet of foil is wrapped around a line of articles so as to form a tube, the tube is pierced at a location between each pair of successive articles by orthogonally-arranged pairs of knives 15-18, and then is contacted by like pairs of folding elements 20-23 which cause the foil tube to tear forming flaps and severance of the tube at the location at which it has been pierced, and which fold the flaps inwardly against the articles. Each folding element may be paired with a respective knife for simultaneous movement therewith and the folding elements and knives moved at the same speed as the tube in its direction of advance during their operation. <IMAGE>
