Abstract: Overlapping sheet articles continuously arriving on a belt conveyor are separated into groups by brake bands which are intermittently pressed against respective rails disposed between the belts substantially flush with the conveying runs. The brake bands lie loosely on the sheet articles which pass thereunder unimpeded until they are to be temporarily halted, which is done by successively lowering a plurality of weights on the brake bands starting at the leading ends of the brake bands.

Abstract: In a composite bag comprising an outer bag and an inner bag which is secured thereto by adhesive, the outer bag is provided with a cross-bottom folded closure at least at one end where no filling valve is provided. Adjacent said one end of the outer bag, the inner bag is closed by a weld seam and folded back on itself and secured in position so that, in a flattened condition of the composite bag when the cross-bottom folded closure lies snug against the bag body, the inner bag extends no further than the centre line of the cross-bottom closure.

Abstract: A bag comprising an inner lining of plastics film and an outer layer of paper comprises a folded closure at least at one end. The folding of the inner lining is incorporated in the folding of the outer layer but is secured by means of separate adhesive. The inner lining and outer layer are made from respective flattened tube sections of which the inner tube section projects from the outer tube section at that end where the folded closure is to be made. During one stage in the folding of the end closure, a tongue formed in the projecting part of the inner tube section is turned over so that at this position the inner tube section is set back from the corresponding edge of the outer tube section.
