Abstract
An apparatus for imprinting, drying, and reeling a fibrous web comprises a hot press including a pair of press members forming a nip therebetween for passage of the web therethrough and at least one clothing arranged to pass through the nip of the press with one side of the web in contact with a surface of the at least one clothing. The apparatus also includes a heat transfer device defining a heatable surface, the heat transfer device being arranged to pass through the nip of the press with the opposite side of the web in contact with the heatable surface, and a heating device operable to heat the heat transfer device such that the heat transfer device heats and dries the web during contact therewith. The apparatus further includes a reel-up including a rotatable reel spool onto which the web is reeled to form a finished roll of web material. At least one of the clothing surface and the heatable surface comprises an imprinting surface for imparting a textured surface to the side of the web in contact therewith in the nip of the hot press. The heat transfer device is arranged to support the web from the press substantially to the reel spool, and can comprise a surface of a surface winding drum, or a substantially rigid sleeve loosely encircling a rotatable roll or a flexible belt looped about a rotatable roll. The reel spool preferably is in nipping engagement with the heat transfer device.
