摘要： A sack made from a tube of plastics material has its bottom constructed by folding an end portion of the tube so as to form two coplanar substantially isosceles triangular flattened portions with spaced confronting bases defined by plain edges and sides defined by fold lines. The space between the bases is bridged by a strip of material that overlaps the bases of the triangles and also projects beyond the base angles of the triangles. The projecting ends of the strip are folded over and the strip is welded to the sack bottom by seams which intersect at the fold lines.

摘要： An apparatus for manufacturing cross bottom sacks from laid-flat tubular sections consists of a frame having:- a table, means for holding the tubular section thereon in a processing station where the ends of the tubular section become opened out into a bottom square or rectangle, a suction gap arranged in the table in the zone of one of the ends of the tubular section, and suction means mounted in the frame above the suction gap and which is able to be raised and lowered for opening one end of the tubular section. Above the plane of the tubular section situated in the processing station, a slide can be extended and retracted over the table in the direction of the median line of the tubular section, the median line of the slide defining with the median line of the tubular section a plane perpendicular to the plane of the tubular section. The width of the slide is less than the interspacing of the hypotenuses of the two opened-out corner folds from each other. The two shaping plungers are designed in a mirror image arrangement and are mounted for being raised and lowered onto the table; their shape corresponds to the shape of the corner folds.

摘要： An apparatus for attaching leaves of a film of a plastic material to laid flat workpieces made of a film of plastic material, consists of a frame with a plate or a table over which the workpieces are continuously conveyed by means of a conveyor device. In a gap of the table plate, there is arranged a pair of conveyor rollers mounted in the frame, and having a roller gap substantially aligned with the table surface; the bottom roller of the pair is a counterpressure roller and the top roller is a suction cylinder. A conveyor cylinder cooperating with the suction cylinder successively delivers the leaves to the suction cylinder. A fishtail nozzle directed towards the roller gap blows heated air into the roller gap in a controlled manner so as to weld the leaf to the workpiece. The suction roller prevents the conveyor cylinder from being heated by the hot air in an inadmissible manner.

摘要： The invention concerns a method and an apparatus for manufacturing a bag or sack bottom from tubular sections of paper or plastic web. Tubular sections of web material are fed into a feeding plane where they are subsequently sealed along selected seams by a sealing means. The sections are then inverted and fed in parallel to a scoring, gluing and folding section. The tubular section is then inverted again and passed to a pressing section. The tubular sections are stacked on top of each other in a partially overlapping manner as they are passed through the pressing section. After pressing, the tubular sections are passed to a separating station for again separating them before being passed to a packaging station. The invention concerns, moreover, an apparatus for operating the above mentioned method.

摘要： An apparatus for the transfer of flat workpieces from a first conveyor to a second conveyor consists of a first conveyor with two endless pulling members circulating parallel to each other over guide wheels or drive wheels which carry in pairs supporting elements with pins. The pins perforating and conveying the workpieces project above a table forming the conveyance path by virtue of the supporting elements and the pins having attachments which run in guides that are parallel to the table and which displace the attachments towards each other. The pulling members of the second conveyor carry in pairs supporting elements with pins which project above a table forming the conveyance path. In the transfer zone of the two conveyors, a plunger is arranged in the frame and mounted in guides. The plunger can be raised and lowered and impales the workpieces onto the pins of the second conveyor. By means of this transfer apparatus, it is possible to convey flat workpieces, in particular those made of a plastic film, through various processing stations. With such an arrangement transition from an intermittent conveying to a continuous conveying is also possible.
