1. A method for assembling a hollow cylinder on a further cylinder, wherein the hollow cylinder comprises a cylindrical body in which openings for creating an air cushion are arranged within a first portion of a shell and a second portion of the shell is designed to be gas-impervious or has openings, for creating an air cushion, of a reduced quantity and/or size compared to the first portion, wherein the openings in the first portion of the shell is connected to at least one gas feed, which is connected to at least one gas inlet on the inside of the cylindrical body, and wherein the further cylinder has openings on a shell and gas can be fed through the openings in the further cylinder via an internal gas supply,
wherein the method for assembling comprises the following steps:
a) providing the hollow cylinder,
b) applying a seal to the first portion of the shell of the hollow cylinder so as to prevent or reduce an escape of gas from the first portion of the shell,
c) providing the further cylinder,
d) applying gas to the further cylinder so that gas escapes from the openings in the further cylinder,
e) pushing the hollow cylinder onto the further cylinder, and
f) removing the seal.
