Abstract:
PCT No. PCT/FR84/00242 Sec. 371 Date Jun. 24, 1985 Sec. 102(e) Date Jun. 24, 1985 PCT Filed Oct. 24, 1984 PCT Pub. No. WO85/01969 PCT Pub. Date May 9, 1985.The outer side surface of the drying cylinder (1) is delimited by a plurality of coaxial rims (2) having the same radius, arranged side by side and separated two by two by an axial space (7), and made of a good heat-conducting material. Each rim (2) is heated and cooled independently from the others by a heating member (8) and a cooling member (11) housed into a subrim (3) surrounding by the rim (2). The heating is provided for example by an electric resistance and the cooling by circulation of cold water, the control being provided by means of remote controlled relays (10). Each rim (2) is rotationally integral with a hub (5) wedged to a drive shaft (6). A comb (26) having teeth (27) engaged into the spaces (7) avoids the winding of material around the cylinder (1) which is in depression conditions in order to favor the heat exchanges by suction of the material against the cylinder (1). Applications to the equipment of dry ends and post dry ends of paper-, cardboard- or other web material machines.
