Abstract: A sequentially timed vacuum grip system holds a sheet and transports it through a folding nip defined by a pair of folding cylinders. At the nip, the folded edge of the sheet is released and simultaneously picked-up by the paired companion cylinder. Additional folds are achieved in the same manner by the use of additional cylinder pairs.

Abstract: A vacuum cylinder is disclosed. The vacuum cylinder may be used in an envelope manufacturing machine, or machines for manufacturing other articles, to facilitate folding of articles about a preformed fold line, such as envelope seal flaps, during the manufacturing process. The vacuum cylinder has at least two rows of suction holes which are arranged at least substantially adjacent to each other and preferably overlap to a certain extent.

Abstract: Device for trouble-free conveyance of products in a folding apparatus both through a nip between two product-guiding cylinders and through a rearwardly extending wedge region bounded laterally by circumferential surfaces of both of the cylinders and at the top by a guiding device for the product to be conveyed includes a compressible covering on a respective one of the cylinders taking over a product, the compressible covering being formed with a plurality of chambers closable off by a section of the product.

Abstract: The machine comprises: a first assembly (2) with receiving, pressure and feed elements (3, 5), through which the part-finished item is fed, and downstream of these two elements a first folder roller (9) with a line of bristles, for folding and glueing the first front flap, and a pair of pressure rollers; a second assembly (20) with receiving, pressure and feed elements in the opposite direction, with a second folder roller (29) and a pair of pressure rollers (39) for folding the second flap, now the front flap; downstream of the second assembly (20) there is an assembly (219) with a transverse conveyor (320) for moving the part-finished item in two opposite directions (fC, fD), with two assemblies (220, 222) for successively folding and glueing the remaining two flaps of the paper.

Abstract: A single continuous dough sheet (12) is conveyed by a conveyor (20) up an incline to a dough tension and drive system (38). In the system (38), the dough sheet (12) passes around a lower drive roller (40), around an intermediate drive roller (42), and around an upper drive roller (44). The dough sheet (12) extends at a downward angle to an idler roller (80) which directs the dough sheet (12) generally vertically downward in a flat condition. A wishbone pushing element (82) having a rounded V-shape forms the first face of the dough sheet (12) into a generally V-shape having two wings. The wings of the V-shape are then guided by an aligning element (96) such as laterally spaced rollers (98, 100) which roll on the opposite face of the wings to form a folded, two-ply continuous dough sheet (14).

Abstract: A folder plow for a web of material in which the plow is positionable transversely of the longitudinal movement of the web material and has a folding disk rotatable on an axis convergent with the web and being adjustable by tilting about its axis of rotation to position its folding edge at different angles to the plane of the web to obtain a wrinkle free fold without gussetting and to prevent marking. The plow has a cylindrical section rotatable about an axis parallel with the plane of the web, which section is partially telescoped over the disk and provides a shroud for a major section of the disk, the disk having a small sector projecting radially from the contiguous portion of the cylindrical section.

Abstract: Process for the production of filters whose active filtering part is made up of a folded filter material web, preferably made from paper, which folded web is delimited in the process by side edges at which the folds terminate, and end edges at which a first or last fold is located, so that in this way filter units (49) are formed. The filter units (49) are produced in an automatized process in which the filter material web is creased and pushed together to form the folds. The spacings between the folds are maintained constant by means of a screw element with threads pushing down between the folds and forming spacing elements between these. The screw element is rotataed during forward movement of the folded web. Glue-coated strips are pressed onto the said side edges of the web, so that the ends of the folds are covered over by the strips.

Abstract: Improved form, fill, and seal machine for making aseptic sealed packages incorporating a plurality of web guiding rollers and flanges for manipulating a continuously fed polyfoil web into a longitudinal tube having a triangular cross section and opposing superimposed web edges that are sealed together to form the longitudinal seal in the tube. Web advance may be continuous or intermittent. Induction heating is used to longitudinally seal the edges of the web together to form a tube.

Abstract: This invention relates to a method and apparatus for folding sheets, and more particularly, to folding sheets and adhering an outer fold to the inner fold to make "outserts" which bear information relating to the pharmaceuticals and which are inserted into the pharmaceutical packages to give instructions and warnings to the users of the pharmaceutical.

Abstract: The present invention relates to second-fold rollers for a folding device adapted for cutting and folding superposed paper webs into a folded section of superposed sheets. The second-fold rollers are arranged in a pair in parallel each other, at least one of which is provided with at least one of non-contact section so formed as to prevent from contacting with the rear corners of the paper sheet to be passed between these second-fold rollers. The non-contact section is a recess partially formed in its cylindrical surface near each end of the second-fold roller.

Abstract: The invention relates to apparatus for folding diapers (1) and like articles, in which apparatus the article is advanced to a folding station by a conveyor (2). The folding station includes a driven folding roll (4) which co-acts with a counter roll (9) in a manner to feed the article to at least one driven transport roll (11,12). The transport roll guides the forward end (10) of the article (1) onto the cylindrical surface of a folding roll (16,17) co-acting with the folding roll (4) and intended, in a first folding phase, to be driven in a first transport direction through a given distance up towards the upper part of the folding roll and, during a second folding phase, to be driven in the opposite direction (A) and move the forward part of the article down from the aforementioned upper part.

Abstract: In a packaging machine for use with a plurality of webs as a packaging material, each of the webs being formed with fold lines extending widthwise thereof and arranged longitudinally thereof at a spacing corresponding to the height of the finished containers to be eventually formed from the web, the plurality of webs being different in the spacing between the fold lines to form containers of capacities which are variable according to the height, a folding apparatus for forming folds in the web by folding the web along the fold lines, comprising a plurality of folding rollers corresponding to the plurality of webs, each of the folding rollers being movable to and retractable from an operative position in which the folding roller is rotatable by the corresponding web when the web is advanced as passed therearound, each of the folding rollers having edges extending axially thereof and coinciding with the fold lines of the corresponding web.

Abstract: A strip (10) of delicate foil is advanced longitudinally along a substantially flat path such as along a platen (104) for printing patterns of lead clusters (12) in photoresist on the foil. A margin (28) of strip (10) is formed into a guiding member such as a standing ridge (98), leaving a residue portion (29) in a desirably flat condition. Ridge (98) has a convenient reference edge (102) and a structural angle is formed by ridge (98) with adjacent foil portions. Such angle is sufficiently strong that advancing strip (10) receives no unacceptable deformation as the reference edge (102) is contacted such as to a reference wall (100) for guidance. Strip (10) is biased so the reference edge (102) maintains contact with guiding apparatus so located that the strip follows the desired path. For example, a flat member (122) is biased downward upon the residue portions (29) of strip (10) and the flat path while a side of member (122) is biased against ridge (98) and the reference wall (100).
