摘要:
In a method and apparatus for withdrawing a selected number of consecutive copies of newspapers (2), for instance, from a series of said products travelling horizontally and arranged in overlapping formation (4), a gripping means in the form of a mechanical clamp (10) is caused to engage with the desired number of copies by the front edge of the clamp (10) being kept in contact with the formation along a selected distance (a), the clamp (10) being driven with a speed (V1) difference in relation to the formation (4, VO) such that a selected number of copies enter the clamp (10) along the selected distance (a). At the end of the distance the clamp (10) is closed and its speed thereafter accelerated in relation to the formation, to a speed (V2) considerably higher than that of the formation (4, VO), its direction deviating only marginally from the direction of movement of the formation. Only a few consecutive copies are withdrawn from the formation (4) so that no gaps occur in the formation (4).
摘要:
A transversal cutting equipment (41) for sheets separable from overlapped continuous forms (23H, 23L), comprising a cutting device (29); introduction devices (28H and 28L) for entering the forms into the cutting device and a singularizing device (46) for overlapped sheets including two transport paths (81 and 82), with differentiable transfer times. The singularizing device comprises a diverter (83) upstream of the transport paths (81 and 82) and in which the introduction devices (28H and 28L) are actuatable for temporarily projecting a leading edge of one of the overlapped forms (23H, 23L) with respect to the other form up to a switching zone of the diverter (83), or for advancing together the overlapped forms. The diverter (83) is configurable for addressing a form or both forms (23H, 23L) to one or to both transport paths and the introduction devices are also actuatable, for lining up the trailing edges of sheets of the one and the other form for a joint cutting of the overlapped forms by means of the cutting device (29).

Um bei einem Verfahren zum Sammeln von Folienabfällen bei Folienablösevorrichtungen, bei denen Abdeckfolien (25) von plattenförmigen Trägern (20) abgelöst und mittels einer Folientransportvorrichtung (22) einer Foliensammelvorrichtung zugeführt werden, eine hohe spezifische Dichte des Folienabfalls zu erreichen, wird vorgeschlagen, daß die Folie am Ende der Folientransportvorrichtung einer Aufwickelwalze (64) zugeführt wird, deren Umfangsgeschwindigket mindestens der der Folientransportgeschwindigkeit entspricht.

Einem von oben beschickbaren Stapelschacht (17) werden mittels einer Förderbahn (11,14) Druckereierzeugnisse (13) in einem solchen Schuppenstrom zugeführt, in dem die Druckereierzeugnisse (13) paarweise deckungsgleich aufeinanderliegen. Um eine ungerade Anzahl von Druckereierzeugnissen enthaltende Stapel bilden zu können, ist im Anschluss an den Auslauf der Förderbahn (11,14) eine Halteeinrichtung (24) vorgesehen, die bei Aktivierung das obere Druckereierzeugnis (13) vorübergehend von dem darunterliegenden abhebt.

摘要:
A combined separating, bursting and sorting apparatus for a continuous web of multi-forms having sheet divisions fixed by perforation lines, provided with a bursting device, a path of travel, and a sorting device consisting of a plurality of receptacles (46-50) for separated and bursted sheets, said path of travel beginning at a plurality of plate-shaped infeed elements (2-7) with connected, elongated, tensioned guide elements (21-26) which extend substantially linearly to a deflection at a receptacle, which infeed elements for inserting a layer of the continuous web of multi-forms are capable of being deflected or swivelled away from each other and are combined to a packet by inserting thin distance plates (14-18) in the side edge regions on both sides of the path of travel and the guide function of a guide element receding at the point of deflection is taken over by a guide plate which extends to the next deflection and follows same, and adjoins the path of travel on one side, the other side of which is formed by belt conveyor means or by conveyor wheels.
