Definitions

the invention relates to a method and its use for changing a final and seamless strip of a machine for producing and / or finishing a paper, cardboard, tissue or another fibrous web in which the band is guided around at least one roller, which the ends is held in support parts of the machine chair.
the support parts of the rollers are held by cantilevers.
the cantilever beams extend across the entire width of the machine and on the drive side of the machine beyond, where there is a fixation on the building structure.
the object of the invention is therefore to simplify the band change while sparing the band.
this object is achieved in that on one side of the machine frame one end of an axially extending to the roller and extending over the width of the belt guide carrier is connected to the support member of the roller, the guide carrier has an axially extending to the roller, outer track, the in the machine over an inner, along the roller extending running track continues, wherein there is a carriage for receiving and guiding the tape on the outer rail, which drives the tape after the removal of intermediate pieces of the machine frame into the machine.
the band By creating the outer track, the band can be prepared unrequited in its entire width outside the machine on the band change. Also, the retraction of the tape by means of the carriage in the region of the inner track designed much easier.
the roller can be held on the guide support, so that no Cantilever- or cross member is required for the Supporteile this roller.
the outer end of the guide carrier should be attached to a crane.
the tape should be brought after fixing on the carriage over axially extending to the roller drapery in a shape corresponding approximately to the course in the machine.
the drapery tubes can be fastened with advantage on the guide support.
the release of the intermediate pieces can be done relatively easily via the lifting of the guide support after loosening corresponding connections in the machine frame.
the guide carrier can be lifted with advantage over the crane or via a lifting element supported on the foundation.
the guide carrier should preferably be connected to the guide part of the machine with the support part.
Particularly non-gatherable are tapes whose surface is harder than that of press felts.
the use of the method is also advantageous in cases in which the strip is guided through at least one press nip formed by the roll and a counter roll for dewatering the fibrous web.
the counter-roller should be held at the ends in support parts, which are interconnected via a cross member, wherein the cross member is guided on the, the guide carrier opposite side of the machine frame out of the machine and fixed there to the building.
This Cantileverung keeps the counter roll with the free support part after loosening the intermediate pieces in their position, thus ensuring the appropriate space for the insertion of the tape. Since this is limited only to the counter-roller, the effort remains relatively low.
the press assembly has a press nip through which the fibrous web is fed together with an upper water-absorbing dewatering belt 2 and a smooth, impermeable belt 1.
the press nip is formed by a lower roll 3 and an upper counter roll 4. These rollers 3,4 are supported by the machine frame, which is supported on the foundation 11.
the machine chair On the driver's side, the machine chair is formed by separate support parts 5, 6 for supporting the rollers 3, 4. These support members 5,6 are releasably connected to each other, with removable spacers 7 between them.
the upper support part 6 of the leader side of the counter roll 4 is connected via an axially extending to the roller 3 cross member 8 with the opposite machine frame.
the cross member 8 is guided on the opposite drive side of the machine and connected to the foundation 11.
the bands are 1.2 guided over guide rollers 10.
the endless circulating transfer belt 1 is not only seamless but also smooth and thus not gatherable, this is performed here with a special changing device in the machine.
the old tape to be changed 1 can be easily separated and removed from the machine.
a guide carrier 14 running axially to the roller 3 is frictionally connected to the support part 5 of the roller 3 on the driver's side of the machine chair.
This guide carrier 14 has an outer, axially to the roller 3 running rail 12 for guiding a carriage 9th
This carriage 9 carries the new tape 1, which is fixed on a winding tube on the unwinding of the carriage 9.
the band 1 can be brought about axially extending to the roller 3 Drapierrohre in a shape corresponding approximately to the course in the machine.
the drapery tubes can be easily attached to the guide support 14.
the band 1 need not be gathered, which in particular protects the smooth surface of the band 1.
the carriage 9 consists here of a sub-carriage at each end of the belt first
the carriage 9 After assembly of the belt 1 in the machine, the carriage 9 can be moved out of the machine and removed together with the guide support 14.
