Falztrichteranordnung zur Verarbeitung einer Bedruckstoffbahn in einer Rollendruckmaschine mit wenigstens drei quer zu einer Bahnlaufrichtung der Bedruckstoffbahn nebeneinander angeordneten Falztrichtern und wenigstens fünf in Bahnlaufrichtung vor den drei Falztrichtern und quer zur Bahnlaufrichtung zueinander versetzt angeordneten Längsschneideinrichtungen zum Längsschneiden der Bedruckstoffbahn in wenigstens zwei Teilbahnen, wobei sowohl die Falztrichter als auch die Längsschneideinrichtungen quer zur Bahnlaufrichtung jeweils separat verfahrbar sind.
摘要:
The invention relates to a printing machine comprising at least one guiding element (308, 501, 710, 720, 720') transversally extending in a transport direction for guiding a strip on a line which is fitted with air-permeable micro-orifices on the surface thereof interacting with said strip. The invention is characterised in that the guiding element (712) associated to the same single strip and inclined at an angle of 45° or 135° with respect to a feed direction, and a folding cone (732) associated to the same single strip are provided with said air-permeable micro-orifices in the area of interaction with the strip
摘要:
The invention relates to a longitudinal folding device (18) with at least two hopper flanks (22, 23) and a paper reversing device (165, 155, 61, 62) that encompasses said flanks in a saucer-type manner, whereby the paper reversing device (165, 155, 61, 62) rests against a machine frame and the longitudinal former (18, 41, 22, 23) in an electrically isolated manner and/or whereby the paper reversing device (165, 155, 61, 62) is entirely or partially connected to one or more vibrators or a mallet (277).
摘要:
The invention relates to a device for drawing in at least one paper web (05, 06, 07, 137, 138, 139, 142) into a roll rotary printing press (18, 26, 27). A draw-in member (33, 34, 87, 124) is provided with permanently fixed pointed bars (35) which can be moved in such a way that said pointed bars (35) penetrate the paper web exclusively during drawing-in.

摘要:
An elongate rail (10) for an equal path folder that has a hollow tube (12) having a a longitudinal axis and a vacuum applied thereto, and a first and second substantially planar surfaces (24, 26) parallel to the longitudinal axis and forming a folding edge (28) therebetween. The hollow tube (12) has at least one opening (18) positioned angularly away from both the first and said second surfaces (24, 26). The vacuum causes a negative pressure to be applied to the opening (18) so that a web substrate passing over the first and second surfaces (24, 26) has at least a portion of the vacuum applied to a face of said web substrate when said web substrate is proximate to at least one of the first and second surfaces (24, 26) thereby substantially reducing particulate matter build-up on the folding equipment and substantially reducing the undesirable particulate matter left on the out-going web product.
