Abstract
The sacks have a sampling opening closed by a pad, starts with a flexible tube formed from welded sheet and having a folding area parallel to its lengthwise axis. The halves of the pad are shaped to fit against the folding area on the inside, and are welded together to form the pad, holding the tube assembled after cutting out of the folding area. The tube is opened by separation of the pad, and spread out as a flat sheet, being then passed in this form over a pipe and a shaping shoulder. The edges of the flat sheet are guided towards each other, and the individual sacks are closed and separated from each other along welded joints perpendicular to the sampling openings.
