<p>A felt, in particular a paper machine felt for the press section of a paper machine, has at least one carrier web and at least one fibre web applied thereto and joined thereto. To ensure that such a felt has improved running properties in spite of adequate transverse stability and can be manufactured at considerably lower costs, the carrier web(s) (45, 50, 57, 58, 64, 71, 72) is or are each formed from at least one carrier web strip (46, 51, 52, 59, 60, 65, 66, 73, 74, 75), whose width is less than that of the carrier web(s) (45, 50, 57, 58, 64, 71, 72) and which is or are helically wound continuously, essentially in the direction of running of the felt (42, 47, 53, 61, 67) at right angles thereto. The manufacture is carried out in principle by the following process steps: a) initially, a web of material is produced; b) at least one carrier web strip (46, 51, 52, 59, 60, 65, 66, 73, 74, 75), whose width is less than that of the finished felt (42, 47, 53, 61, 67), is fixed to the web of material; c) the web of material is moved in the peripheral direction; d) the build-up of the first carrier web (45, 50, 57, 58, 64, 71, 72) and, if appropriate, further carrier webs (45, 50, 57, 58, 64, 71, 72) takes place by means of a relative motion between the particular carrier web strip (46, 51, 52, 59, 60, 65, 66, 73, 74, 75) and the part (41), already built up, of the felt (42, 47, 53, 61, 67), helically at right angles to the direction of revolution of the web of material; e) each carrier web (45, 50, 57, 58, 64, 71, 72) is joined to at least one fibre web (43, 44, 48, 49, 54, 55, 56, 57, 62, 63, 68, 69, 79). <IMAGE></p> |
