Abstract (en)
[origin: EP0331817A2] A cylinder arrangement comprising two cylinders (3 and 4) which are parallel in respect of their axes of rotation (2) is used for consolidating fleece (1) in between them by means of heat and/or solvents. The two cylinders (3 and 4) have on their surfaces individual knobs (7 and 8) which are spaced apart and stand out relative to the actual cylinder surface (9 and 10). The knobs (7) on the one cylinder (3) fit between the knobs on the other cylinder and, in use, reach into the spaces between the knobs (8) on the other cylinder. The upper surfaces (5 and 6) of the knobs (7 and 8) on the cylinders (3 and 4) are close or very close to the smooth surface (9 and 10) of the opposite cylinder between the feet of the knobs thereon. Thus, the respective consolidation points (11) of the fleece (1) are mutually offset in height by the height of the knobs or the distance between the surfaces (9 and 10) of the cylinders (3 and 4). <IMAGE>
