Abstract: An apparatus for supplying individual blanks stacked sideways in a store with an inclined conveyor channel comprises a divider with a conveyor for receiving, under control, a divided sequence of blanks from this conveyor channel, two oppositely inclined planes following closely on from the conveyor channel and above this divider and an oscillating device with a reciprocating movement provided with suction cups for taking up the blanks in individual sequence from the divided sequence and depositing them in a horizontal position on a production line.

Abstract: A sealing device with multiple differential action is provided for machines producing dual-use filter sachets for infusion products. In such machines a continuously moving strip of thermally weldable filter paper, fed with equidistantly spaced fractional doses of the infusion product, is progressively folded longitudinally into a flattened tubular shape with adjacent folded-back longitudinal edges forming a longitudinal crest. The device is constituted by two blocks having respective pairs of mirror-image stepped overlapping edges extending to the opposite sides of the adjacent folded back edges of the strip forming the longitudinal crest. The mirror-image edges of the upper overlap have bores connected to a fluid-dynamic heat source. The mirror-image edges of the lower step have a lamellar structure.

Abstract: A method of producing packaging boxes starting from pallets of sheets of board each having stamped therein a plurality of plane blanks joined in adjacent transverse and longitudinal strips by connections which can be broken and are provided with notches, fold lines and break lines defining the members for producing and closing the boxes. The method involves a sequence of steps consisting in the sequential take-up of the sheets from the pallet and the sequential separation of these sheets into strips and the separation of the strips into individual plane blanks which are supplied in individual succession to a box production line along which a respective portion defined by one of the break lines is separated and reapplied in order to obtain boxes of the flanged type after they have been folded internally around the fold lines and the production and closure members have been glued.

Abstract: An apparatus for collating dual-use filter sachets obtained from a flattened tube of thermally weldable filter paper comprising multiple bags or pouches defined by transverse thermal welds in continuously operating production machines and provided with labels, threads and tabs for attachment of the matter. The apparatus has a cutter for cutting up the tube, into portions having at least two pouches, across the attachment tabs. A device then folds in bellows-shape, these portions along the intermediate transverse thermal weld and operates in combination with a device having conveying pincers for conveying the folded bags to a pickup and transfer device through a fixed folder so as to set up the pouches back to back transferring them as thus folded to a welder for welding together the thus adjoining extremists thereof.

Abstract: An apparatus with a rotary wheel for applying, to a flattened tube of thermally weldable filter paper forming dual-use filter sachets having multiple bags or pouches defined serially by transverse thermal welds in machines for continuously producing the filter sachets, labels spaced relative to the transverse median line of the alternate transverse thermal welds, as well as a longitudinal thread transversely on the labels and thermally weldable stickers or tabs across these alternate transverse therman welds. The rotary wheel had a plurality of equidistantly spaced heads comprising heating elements as well as pickup and infeed elements for the labels, the thread and the tabs, and further a plurality of devices with pincer elements interposed between the heads designed to fold the thread in a loop. Pressure pad elements cooperate in counter-rotation of the heads.

Abstract: An apparatus for the conditioning in envelopes of individual dual-use filter sachets, obtained from a flattened tube of thermally weldable filter paper, having multiple bags or pouches defined by transverse thermal welds in continuous production machines, with labels, thread and fastening tabs for same, cutting the tube into portions comprising at least two pouches across the fastening tabs, folding the portions in fan-shape along the intermediate transverse thermal weld and setting up these pouches adjacent to each other for joining the corresponding adjacent extremities. Such an apparatus has a device for feeding portions of packing paper located underneath said multiple pouches folded into fanshape between the folding and transfer unit capable of transferring the pouches through a fixed folder effecting a U-shaped fold between the prongs of pincers of an intermittently rotating pincer wheel for joining the aforesaid adjacent extremities and for peripherally sealing the envelope enclosing the sachet.

Abstract: A filter bag for insusion products is provided having multiple successive container pockets or lobes, each for infusing a corresponding dose or unit quantity of product. The bag structure permits two usage layouts. The flat layout form is for packaging in lots for sale with said lobes superimposed or folded one over the other or side by side. The other layout form has the lobes opened out or distended following the pick up and pull of the corresponding tag (label) ending in the thread for handling the filter bag at the time of usage. The thread has a length equal to that of the bag as laid out for use with the pockets or lobes distended. The thread is fixed to the opposing ends of said bag by means of a piece of heat weldable material together with the non heat weldable paper tag (label) adjacent to one of said opposing ends.
