The present invention relates to a method and a device for picking-up and opening in the shape of elongate bags for automatic packing of cylindrical articles, preferably can lids. The method is charaterized by picking-up essentially flattened packages from a package magazine by means of pick-up means, opening the individual package by application thereon, at least in the area of the opening-mouth end of bags, of surface-holding means to opposite sides of the package and thereafter moving said means away from the package and then moving said means apart whereby the package mouth is distended. the device comprises magazine (1) for holding essentially flattened packages, a pick-up means (2) picking up packages from said magazine, package-opening, surface-opening means (3, 6) arranged to be applied on opposite sides of the individual package in the area of the mouth-opening end thereof and to open up the mouth of said package while being displaced away from one another in an essentially perpendicular direction relative to the plane of said package, and distending means (7,8) arranged to be inserted through the opening mouth of the package and thereafter to be moved apart, thereby to force open the mouth of the package.
