Claims (10)

1. Fremgangsmåde til demontage af en kappe på en roterbar og radialt forskydelig valse, hvor valsen er en valse til et trykværk i en trykmaskine, eksempelvis en fle-xo-trykmaskine, hvor valsen ved en første ende er med en første akselende i et første leje og ved den anden ende er med en anden akselende i et andet leje, hvor disse lejer er arrangeret i to radialt forskydelige slæder på trykmaskinen, og hvor valsen kan frigøres fra trykmaskinen ved valsens ene ende, kendetegnet ved, at valsen forskydes aksialt i sin længderetning forud for demontage af en kappe, hvorved valsen trækkes ud af indgreb med den ene radialt forskydelige slæde, hvorefter den nævnte slæde og valsen forskydes i radial retning i forhold til hinanden, og hvorefter kappen frigøres og demonteres ved, at den trækkes af valsen i dennes længderetning.A method of disassembling a sheath on a rotatable and radially displaceable roller, wherein the roller is a roller for a printing machine in a printing machine, for example a flexo printing machine, the roller at a first end having a first shaft end in a first bearing and at the other end is with another shaft end in a second bearing, wherein these bearings are arranged in two radially displaceable slides on the printing machine and the roller can be released from the printing machine at one end of the roller, characterized in that the roller is axially displaced in its longitudinal direction prior to disassembly of a sheath, whereby the roller is pulled out of engagement with one radially displaceable carriage, after which said carriage and roller are displaced in a radial direction relative to each other, and then the sheath is released and dismounted by pulling the roller in its longitudinal direction. 2. Fremgangsmåde ifølge krav 1, kendetegnet ved, at den nævnte aksiale forskydning af valsen i dennes længderetning også omfatter en forskydning af i det mindste en del af den anden slæde, hvori valsens anden ende er lejret med det andet leje.Method according to claim 1, characterized in that said axial displacement of the roller in its longitudinal direction also comprises an displacement of at least part of the second carriage in which the other end of the roller is mounted with the second bearing. 3. Fremgangsmåde ifølge krav 1 og 2, kendetegnet ved, at den nævnte aksiale forskydning af valsen foretages med samme mekanisme, som under drift af trykværket anvendes til at regulere valsens placering i sideregisteret i forhold til yderligere trykværk i trykmaskinen.Method according to claims 1 and 2, characterized in that said axial displacement of the roller is carried out with the same mechanism which, during operation of the printing plant, is used to control the position of the roller in the lateral register relative to additional printing works in the printing machine. 4. Fremgangsmåde ifølge et hvilket som helst af kravene 1 - 3, kendetegnet ved, at den nævnte radiale forskydning foretages med samme mekanisme, som anvendes til at regulere valsens radiale placering i forhold til andre valser i trykværket.Method according to any one of claims 1 to 3, characterized in that said radial displacement is made with the same mechanism used to regulate the radial position of the roller relative to other rollers in the printing plant. 5. Fremgangsmåde ifølge et hvilket som helst af kravene 1 - 4, kendetegnet ved, at det første leje ved valsens første ende trækkes ud af den første slæde ved den nævnte aksiale bevægelse.Method according to any one of claims 1 to 4, characterized in that the first bearing at the first end of the roller is pulled out of the first sled by said axial movement. 6. Fremgangsmåde ifølge et hvilket som helst af kravene 1-4, kendetegnet ved, at den første akselende ved valsens første ende trækkes ud af det første leje ved den nævnte aksiale bevægelse.Method according to any one of claims 1-4, characterized in that the first shaft end at the first end of the roller is pulled out of the first bearing by said axial movement. 7. Trykmaskine med i det mindst ét trykværk, eksempelvis en flexo-trykmaskine, hvor en eller flere valser i nævnte trykværk er med en udskiftelig kappe på en roterbar og radialt forskydelig valse, hvor valsen kan frigøres fra trykmaskinen ved valsens ene ende, hvor valsen ved den ene ende er arrangeret med en første akselende i et første leje og ved den anden ende er arrangeret med en anden akselende i et andet leje, hvor disse lejer er arrangeret i to radialt forskydelige slæder på trykmaskinen, kendetegnet ved, at valsen er med forskydningsmidler til forskydning i sin længderetning, fortrinsvist imellem 30 og 80 millimeter, og hvor trykmaskinen ved valsens første ende er med en fast og radialt forskydelig slæde.7. A printing machine having at least one printing machine, for example a flexo printing machine, wherein one or more rollers of said printing plant have an interchangeable sheath on a rotatable and radially displaceable roller, where the roller can be released from the printing machine at one end of the roller, wherein the roller at one end is arranged with a first shaft end in a first bearing and at the other end is arranged with a second shaft end in a second bearing, these bearings being arranged in two radially displaceable slides on the printing machine, characterized in that the roller is provided with displacement means for longitudinal displacement, preferably between 30 and 80 millimeters, and wherein the printing machine at the first end of the roller has a fixed and radially displaceable carriage. 8. Trykmaskine ifølge krav 7, kendetegnet ved, at valsen ved den anden ende er lejret i et forskydeligt lejehus i en anden slæde, hvor lejehuset er forskydeligt i valsens aksiale retning, og hvor lejehuset og akselende fortrinsvist er med mere end et leje.Printing machine according to claim 7, characterized in that the roller is mounted at the other end in a slidable bearing housing in a second carriage, the bearing housing being displaceable in the axial direction of the roller and the bearing housing and shaft preferably having more than one bearing. 9. Trykmaskine ifølge kravene 7 og 8, kendetegnet ved, at trykmaskinen ved den første slæde er med midler til optagelse, fastholdelse og frigørelse af et eller flere lejer, der er fastmonteret på valsens første akselende.Printing machine according to claims 7 and 8, characterized in that the printing machine at the first carriage is provided with means for holding, holding and releasing one or more bearings mounted on the first shaft end of the roller. 10. Trykmaskine ifølge kravene 7 og 8, kendetegnet ved, at trykmaskinen ved den første slæde er med et eller flere fastmonterede lejer, hvor valsens første akselende er med midler til optagelse, fastholdelse og frigørelse af et eller flere lejer.Printing machine according to claims 7 and 8, characterized in that the printing machine at the first carriage has one or more fixed-mounted bearings, the first shaft end of the roller being provided with means for receiving, holding and releasing one or more bearings.
