An apparatus for supplying a coil-like padding product for packaging purposes comprises a supply device for supplying a web-type padding material and also a rolling-up apparatus, which rolls up the web-type padding material to form the coil-like padding product. It is proposed that the rolling-up apparatus should comprise a flexible delimiting means, which can form an at least partially curved delimiting wall of an at least temporarily present rolling-up space, of which the extent is preferably alterable and which has an inlet for the web-type padding material, it being possible for the web-type padding material to enter into the rolling-up space through said inlet, wherein the web-type padding material is guided by the at least partially curved delimiting wall, this resulting in the formation of the coil-like padding product.

A holding and supporting group of a winding spindle in a machine for winding plastic film onto spools includes a winding reel positioned between two uprights, wherein a first upright carries a rotating plate which cantilever-supports three spindles and a central shaft, wherein the central shaft is supported at the other end by the second upright, wherein, in correspondence with a free end of the central shaft, there is a star-shaped plate with three supporting arms for each free end of the three spindles through a respective toggle lever mechanism driven by an actuator carried on a lever articulated with respect to the star-shaped plate, and in turn caused to oscillate between an operative blocking position of the respective spindle and a rest position for releasing the respective spindle by an additional actuator.

A method accurately determines internal stress in a film roll and prevents defects in the film roll. A film winding device includes a take-up roller and a winding tension adjustment device. A calculation device uses a winding equation in which a winding tension function is explicitly expressed, the winding tension function expressing a winding tension as a function of a radius of a core. The winding tension adjustment device controls winding tension in accordance with a winding tension distribution function calculated by the calculation device.

A coiling device includes a coiler (1) having a coiling mandrel (3) for coiling a metal strip (2) which is fed (x) to the coiler (1), and a coiling swing arm (4) having a front and a rear pressure roller (5, 6) and a deflection plate (7). A swing arm drive (8) lines up the coiling swing arm (4) with the coiling mandrel (3) and is driven away from the coiling mandrel (3). An upper duct flap (9) upstream of the coiler (1) in the feed direction (x) for guiding the metal strip (2). A flap drive (10) for positioning the upper duct flap (9) such that, when the coiling swing arm (4) is lined up with the coiling mandrel (3), the upper duct flap is arranged between the coiling mandrel (3) and the front pressure roller (5) of the coiling swing arm (4) or is arranged upstream of the front pressure roller (5) of the coiling swing arm (4). In the first-mentioned case, the metal strip (2) is deflected around the coiling mandrel (3) only by the rear pressure roller (6) and the deflection plate (7) of the coiling swing arm (4) and, in the last-mentioned case, additionally also by the front pressure roller (5).

The present invention provides an adaptive control system to control a plant using direct output feedback in which a function of the full plant state, as opposed to estimates thereof, is used for feedback control of the plant. The adaptive control system of this invention is therefore highly useful in the control of plants, particularly plants for controlling the physical properties of rolls of web material and more particularly a calendering apparatus. Accordingly, in a particularly preferred embodiment the adaptive control system of this invention controls loading of a calender apparatus, such as a pair of opposed rolls forming a calendering stack, based upon the physical properties of a previously processed web.
