Abstract: An apparatus for folding envelope blanks comprises a plurality of platform assemblies which are rotatably mounted on a base. The platform assemblies are incrementally advanced around the base, and separate mechanisms located around the periphery of the base perform the individual folding operations. Particular advantages are achieved by including the side flap folding mechanism on the platform assemblies so that the folded flaps are held firmly in place until the envelope is removed from the machine.

Abstract: Blanks are produced from a continuous sheet (3) of material comprised of plastic-coated paper. Said blanks are conveyed on an expanding mandrel carousel (13) to a bottom weld flap forming station (17) and then transferred to a filling carousel (19). The packages which have been formed from the blanks are filled at a filling station (20) and sealed at a top seam welding station (23). A top weld flap forming station (26) and a top weld flap sealing station (29) are disposed on a top forming carousel which adjoins the filling carousel (19). The finished packages are discharged at a discharge station (30), to a discharge turntable (31). The machine may be used for manufacturing packages for liquids, e.g. milk or juices.

Abstract: A machine for the processing of packing containers of the type used for example for milk products. Such packing containers are manufactured from a filled material tube and are first given cushion-shape. With the help of the machine in accordance with the invention they are subsequently converted to a substantially parallelepipedic shape.The machine comprises a means of transport in the form of a wheel (35) having radial holding devices (37) for the cushion-shaped semi-finished products (2). The means of transport can be rotated step-by-step so that each individual packing container passes around processing stations (45-50) placed around the periphery of the means of transport for the folding of corner lugs, sealing and shaping.

Abstract: Apparatus for packaging cigarettes, the apparatus comprising means for applying a strip of packaging material about a group of the articles to form a tube and folding and gluing the ends of the wrapper to define the package is provided with a plural stage drying apparatus which permits a long glue drying operation without adversely effecting the speed of operation of the packaging apparatus. The drying apparatus includes a pair of adjacent, synchronously rotated, drums which have receiving cells for the packages. The packages are transferred, typically in pairs, into individual cells of a first drum and are subsequently simultaneously transferred from cells in the first drum into cells of the second drum.

Abstract: A packing machine for cigarettes, in particular for soft packs, with a plurality of pack-forming assemblies 1-16, has at least one operating member 21-23 in each assembly which is movable, e.g. to clamp a sheet of foil 300 or a paper lable 400 against a packet mandrel 20. The assemblies are each indexed past a number of stations at each of which a drive shaft 33 (FIG. 3) engages a coupling shaft 35 connected to the respective operating member. The shafts lie perpendicular to the direction of movement of the assemblies and they engage with one another through a tongue 34 and fork 36 coupling.The coupling shaft 35 may be connected to the operating member through an eccentric 52 or, where the operating member has to be moved linearly, through a rack and pinion 61.

Abstract: This relates to a drive system for selectively positioning a heat sealer and a cooler relative to mandrels supporting bags or pouches, which mandrels are carried by a turret and indexed thereby. A simple oscillating shaft driven by a cam oscillates a double ended lever which, in turn, serves to oscillate wedge shaped cam members so as to simultaneously actuate two sets of heat sealers and coolers with each heat sealer and cooler being carried by a separate support arm.

Abstract: This relates to a bag forming machine wherein a continuous tube is formed from a contuous web, the tube having a side seam and being cut off at predetermined intervals to form short tubes with closed bottoms. The tubes are placed on mandrel assemblies of a turret and the mandrel assemblies, as the turret is indexed, are actuated so as to axially elongate the closed tubes while holding the open end of each tube against movement, thereby generally forming a flat bottom on the tube and triangular bottom portions. The turret is next indexed so as to plow down the triangular bottom portions flat against the flat bottom portion followed by further indexing of the turret to heat seal the triangular positions to the flat bottom portion and then cool the heat seals. Finally, each closed bottom bag is gripped by a combined rotator and orientation device wherein the side seam of the bag is rotated to a selected orientation.
