发明名称 Method and machine for producing an imprinted continuous web
摘要 The invention relates to a method associated with a machine arrangement in a machine for production of an imprinted continuous web (1) of fiber material with a cellulose content, preferably a soft paper web, at which a wet web (1) is fed through a roll nip (34) together with at least one endless clothing (32, 35), which, or of which at least one have the ability to receive and to transfer away water from the web (1) and that the roll nip (34) is a web (1) imprinting roll nip (34) and that the wet web (1) has a low enough dry solids content to allow remolding of fibers in the web (1) during the passage through the roll nip (34), so that the web (1) acquires a structure with areas with different density, after which the clothing or the clothings (32, 35) are transferred away from the web (1) after the roll nip (34), the web (1) is dried with at least an essentially maintained structure, and the dried, imprinted web (1) is reeled up in a reel-up (2). The characteristic features of the invention is that the web (1) is pressed and dried in a heat press (50), which have at least one heat transfer device (6, 45, 54) with a heatable surface (7, 51, 59), which is heated up by a heating device (38), and which surface (7, 51, 59) is in contact with the web (1), which heatable surface (7, 51, 59) runs through the roll nip (34) together with at least one clothing (32, 35) which feeds the web (1) so that the web (1) is enclosed between the clothing (32, 35) and the heatable surface (7, 51, 59) and which heat press (50) is integrated with the reel-up (2).
