Abstract: A heating device of a two-sided machine has a stand which has a first arcuate hot plate and a wall on which a sleeve is provided. A second arcuate hot plate is arranged above the first arcuate hot plate. The second arcuate hot plate is connected to the sleeve by a connecting stem. The stand includes a cylinder unit, the piston rod of which is connected to the trailing end of the second arcuate hot plate. A second corrugated-cardboard ply and a first corrugated-cardboard ply are guided so as to run between the hot plates, whereas a third corrugated-cardboard ply is guided so as to run, above the second arcuate hot plate, through the second arcuate hot plate. The second arcuate hot plate is lowered by the cylinder unit in order to be placed in connection with the second corrugated-cardboard ply.

Abstract: A hollow roller, which is heatable with steam, has an inner wall. It is rotatably mounted and has a steam supply channel opening into the interior and a siphon pipe, which opens into the interior coaxially to a centre longitudinal axis, with a suction opening located adjacent to the inner wall. The siphon pipe is held in a rotary feed-through, which is pivotable relative to the centre longitudinal axis of the hollow roller about a pivot angle ? in such a way that the spacing b of the suction opening from the inner wall is adjustable.

Abstract: A heating device (1) for a corrugated cardboard installation includes several heating plates (3), arranged successively in the direction of advance of a corrugated cardboard web (2). Heating device (1) also includes at least one pressure unit (5), consisting of a bearing (6) arranged diagonally or transverse with respect to the direction of advance of the corrugated cardboard web (2). At least one pressure element (7) is attached to the bearing (6). The pressure element (7) is connected with the bearing (6) in a freely movable manner via at least one elastic medium (11). The elastic medium transfers the weight of the bearing (6) to the pressure element (7).

Abstract: A heating device (1) for a corrugated cardboard facility includes several heating plates (3) arranged sequentially along a path in the advancing direction of a sheet of corrugated cardboard (2). Compression elements (4) are arranged above the heating plates (3) in position to act on the sheet of corrugated cardboard (2) as it advances along the path. An intake belt (e) is located in a starting area (a) of the heating plates (3) between at least a part of the sheet of corrugated cardboard (2) and at least one compression element (4.1, 4.2).

Abstract: Apparatus for feeding a web of material, in particular a web of cardboard, having at least one driven element which engages one surface of the web of material to be fed, and which cooperates with at least one bearing element acting upon the other surface of the web of material, a contact-pressure force for generating a frictional force exerted on the web of material, at least one bearing element or the at least one driven element is acted upon by a contact-pressure device, a sensor for detecting the feeding speed of the web of material which delivers to a control unit which operates to control the feeding speed signal of the contact-pressure device so that the difference between the detected web speed and a set-point speed signal applied to the control unit is essentially equal to zero.
