Abstract: The invention relates to a turning apparatus for a production plant (2) for sanitary products, in particular adult or baby diapers, the turning apparatus having a drum (12) which rotates about a geometrical drum rotational axis (11), and at least one plate (14) which is spaced apart radially from the drum rotational axis (11) and is coupled to the drum (12), which plate (14) comprises a suction face (15) for the transport of sanitary material pieces (16), which suction face (15) holds the respective sanitary material piece (16) by means of a vacuum during the transport, the plate (14) having a geometrical vertical axis (17) which runs radially with respect to the drum rotational axis (11), the plate (14) receiving the sanitary material piece (16) with a first orientation about the vertical axis (17) in a first transfer region (18), and transporting the sanitary material piece (16) from the first transfer region (18) to a second transfer region (20) along a setpoint transfer path (19) which runs in the circumf

Abstract: A gluing station for applying glue to product elements guided in a product stream is intended to permit continuation of the production process and gluing of the product elements in a particularly simple and reliable manner even after a temporary machine stop or production standstill. For this purpose, according to the invention, a moistening system is assigned to a glue application roller that can roll on the product stream. During operation of the gluing station, in the event of a stopped product stream, the glue application roller is pivoted away from the product stream and the transfer roller for the duration of the standstill and is kept rotating, whereby the surface of the glue application roller is moistened.

Abstract: A method for supplying and inserting document sets into associated envelopes, in which the document sets are supplied to an insert station in a document material stream and the envelopes are supplied to the insert station in an envelope material stream, to allow mail pieces to be collated with high reliability. In the insert station, the document set supplied in each case is inserted into the relevant envelope supplied at the same time, wherein for each document set, the position thereof in the document sequence and an associated document identification code are determined, and for each envelope, the position thereof in the envelope sequence and an associated envelope identification code are determined, and a document set and an envelope are supplied to the insert station only as a pair when it is confirmed that the envelope pending supply is individually associated with the document set pending supply.

Abstract: An adhesive application device for applying, includes a nozzle unit having a number of nozzles for applying an adhesive to a material which is moved along a direction of transport, said nozzles being displaceable transversely to the direction of transport along a first guide spindle; and plural individual gluing heads, each being arranged separately from each other on respective second separate guide spindles, so as to be displaceable transversely to the direction of transport.

Abstract: In a method for forming product stacks of folded or unfolded product blanks made of paper or chemical pulp, product blanks are supplied consecutively to a stacking surface and placed in an upright position. A separating element is inserted between two consecutive product blanks as the product blanks are moved against a channel wall of a discharge channel for temporary support of a rear side of the product blanks, to thereby form a first product stack with a predetermined number of product blanks between the separating element and the channel wall. The channel wall is opened to thereby allow the first product stack to be transferred to the discharge channel, and a sliding element is inserted between the product stack and a subsequent second product stack, as the first product stack is moved to the discharge channel.

Abstract: An adhesive application device for applying an adhesive to a material which is moved along a direction of transport x, comprising a nozzle unit having a number of nozzles for applying the adhesive to the material should be able to process gluing patterns of different sizes particularly flexibly and efficiently in a very simple manner. For this purpose, the nozzle unit is arranged to be displaceable transversely to the direction of transport x along a first guide spindle.

Abstract: A device for folding foldable blanks device includes a conveyor belt for conveying the blanks and a folding cylinder for receiving a first region of a blank from the conveyor belt, wherein the conveyor belt is provided with a plurality of suction openings which are arranged such that, by means of a vacuum unit assigned thereto, the suction openings hold a second region of the foldable unfashioned piece on the conveyor belt at least during folding.

Abstract: A device to stamp a number of creases into a material layer is provided, the device comprising a main roller body non-rotationally arranged on a rotating shaft and a number of holding elements sunk into the main roller body that serve to position and/or affix a first foil having a first creasing ridge on the circumferential surface of the main roller body, which is characterized in that a holding device is provided that can be angularly rotated relative to the longitudinal axis of the rotating shaft and that is configured to position and/or affix at least one additional second foil having a second creasing ridge.

Abstract: A foil cutter for use on the surface area of a carrier roller of a rotary punch has a base plate with a bottom and a top, and at least one blade arranged on the top of the base plate. The top of the base plate has at least one region bordering on the at least one blade and partially or completely surrounded by the at least one blade, in which at least one foil cutter perforation is present through which at least a part of punched flat material can be drawn by suction to be held in the region and be further transported by the carrier roller. The foil cutter has at least one elevation arranged on the top of the base plate in the at least one region bordering on the at least one blade and partially or completely surrounded by the at least one blades.
