    摘要: In an apparatus for separating flattened valved sacks which are reeled in an overlapping formation, the reel is turned by endless belts pressing on the reel periphery as the overlapping sacks are being taken off the reel. A roller presses the overlapping sack formation onto the belts and this roller is disposed at a spacing of no more than about one sack length from the point where the sacks leave the reel.

    摘要: Bags are fabricated from tubular plastics film as they are being filled. A flattened severed tube section of the bag material is clamped across its entire width at the bottom but only near the folded longitudinal edges (or the side pleats if such are provided) at the top. The walls of the tube section are pulled apart at the top between the clamped regions to present a filling aperture and welded together at the bottom across the entire width below the clamped region. After the contents of the bag have been inserted through the filling aperture, the top of the tube section is welded shut above the clamped regions and the bag is discharged.

    摘要: Lifting gear for a filled sack comprises a pair of clamping bars between which the gathered and flattened mouth portion of the sack can be clamped after the mouth portion has been slung thereabout. The bars are in the form of parallel cantilever arms and rotatable about an axis parallel thereto, one of the bars also being displaceable to and from the other bar while remaining parallel thereto.

    摘要: Apparatus for cooling tubular plastic films extruded from a film blowing head. Air cooling means consisting of co-axial pipes extending axially through the film blowing head supply the cooling and inflating air and withdraw the same from the inflated parison. Vertically inner cooling rings are disposed substantially concentrically to the axis of the parison downstream of the annular extrusion die orifice of the blowing head. The inner cooling rings define nozzle gaps and have air guiding surfaces, which face the wall of the parison and are convexly curved in a longitudinal section of the inner cooling rings and during the operation of the apparatus are swept by the cooling air blown out of said nozzle gaps. An outer cooling air jet concentrically surrounds the extruded parison and serves to blow air in a direction which is approximately parallel to the direction of travel of the parison. The inner cooling rings are concentric to the parison. A telescopic inner pipe is provided and includes axially spaced annular gaps serving to withdraw the cooling and inflating air. The outside diameter of the lowermost internal cooling ring is substantially as large as the inner diameter of the annular extrusion die orifice. The diameters of the inner cooling rings progressively decrease in an upward direction so that the parison will assume an upwardly tapering, frustoconical shape having a small included angle before it is inflated.

    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: A separating device for severing perforated tube sections includes an advancing mechanism and a tearing mechanism which respectively include opposing rollers or cylinders which are situated on both sides of the tubular web to be separated and over which endless transport bands are guided. The rollers or cylinders of the tearing mechanism can be moved in the direction toward the tubular web by a control element. The opposing rollers or cylinders in the tearing mechanism are respectively situated in swivel arms that are arranged such that they swivel around swiveling axes that oppose one another in the transport direction of the tubular web and the swivel arms swivel apart in opposite directions.

    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.
