Abstract
A device for guiding material webs (A through D; E through H) via an angle-bar deck (2), including a folding section that is arranged on a plurality of planes (3.1, 3.2, 3.3), from where the material webs (A through D), (E through H) enter folding apparatuses (4), (5). Accommodated on longitudinal folding devices (8), (9) are infeed elements (7), which have guide sections (13), (14) that are able to be operated independently of one another.
Claims17
A device for guiding webs of material, via an angle-bar deck for a folding section that is subdivided into a plurality of planes, from which the webs enter folding apparatuses, the device comprising:
- longitudinal folding devices;
- and
- at least one infeed element accommodated at the longitudinal folding devices, the infeed element having a first and a second guide section, the first guide section being operable independently of the second guide section.
A folding-apparatus superstructure for guiding webs of material via an angle-bar deck comprising:
- folding sections disposed in a plurality of planes, from which the webs enter folding apparatuses;
- longitudinal folding devices;
- and
- at least one infeed element accommodated at the longitudinal folding devices, the infeed element having a first and a second guide section, the first guide section capable of being driven independently of the second guide section.
A folding-apparatus superstructure for guiding webs of material via an angle-bar deck comprising:
- longitudinal slitting devices for dividing the webs into at least two partial webs;
- folding sections disposed in a plurality of planes, the webs entering folding apparatuses at the planes;
- longitudinal folding devices;
- and
- at least one infeed element accommodated at the longitudinal folding devices, the infeed element having a first and a second guide section, the first guide section capable of being supported independently of the second guide section.
A folding-apparatus having a superstructure for guiding webs of material comprising:
- longitudinal slitting devices for dividing the material webs into at least two partial webs;
- folding sections disposed in a plurality of planes;
- longitudinal folding devices;
- and
- at least one infeed element accommodated at the longitudinal folding devices, the infeed element having a first and a second guide section, the first guide section being operable independently of the second guide section.
A web-processing rotary press comprising:
- a device for guiding material webs via an angle-bar deck having a plurality of longitudinal roller devices disposed on a plurality of planes;
- and
- longitudinal folding devices;
- and
- at least one infeed element accommodated at the longitudinal folding devices, the infeed element having a first and a second guide section, the first guide section being operable independently of the second guide section.
