The combined ram 20 and upper chamber 35 is moved along vertical posts 29 by two or three screw-threaded shafts 10, 11 driven, through pulleys 16, 17, by a motor 7 housed in the upper ram 9. The lower chamber 39 is mounted on wheels 41 and attached to a door (6), Fig. 2 (not shown), so that opening of the door withdraws the chamber. The upper chamber is similarly mounted in the ram 20 and may be attached to the door by a catch or moved by a pivoted handle 38. Ribs 34 may be provided on the upper ram and/or in the upper chamber 35, and elastic scraping seals 32, 33 on the ends of both rams. Two switches (47) and a current switch control the motor so that the ram 20 reverses at a predetermined current and returns to the initial position or to one in which one of the scrapers 32, 33 seals the corresponding chamber. In the latter event the door (6) cannot be opened until a further switch is operated. At their tops the chambers may have internal seals to engage the rams; the chambers may also have outer beads against which a rubber ring may clamp a lining bag.

Abstract: 1366440 Plastics bags W ACHERMANN and F ACHERMANN 17 Nov 1972 [19 Nov 1971 2 Nov 1972] 53307/72 Heading B8K A plastics bag is closed at its top by tying together diagonally opposite flaps 6, the second pair being tied on top of the first pair. Alternatively, the first diagonal pair may be merely folded one on top of the other and the second pair then tied. In another form, Fig. 9, two flaps 6 are provided at one side only of the bag, the remaining material at the top being gathered as at 6<SP>1</SP> and the flaps 6 being teid therearound as indicated by the arrows. In a further form, Fig. 20, flaps 26 are formed by.a slit 24, 24a, and if the bag has a gusseted side the single slit causes a portion 31 of the gusseted side to be cut out. By providing a curve at the lower ends of the cuts the projecting portions are strengthened and are less likely to tear. The bags may be cut from a tube by sealing the tube transversely to form the bag bottom and providing a line of perforations so that the bags can be separated. The slits 24, 24a may also be merely lines of perforations which are torn when the filled bag is to be closed, these perforations being of wider spacing than those by which successive bags are separated. The pair of flaps 6 may be formed from a single cut which also separates the bags, a tap being left at the bottom of each bag corresponding to the cut-out on the following bag (Figs. 21, 22, not shown). The bags may be reinforced by inserts of ribbon, string or wire and the bag surface may be roughened.
