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 wrinkle or misaligned winding caused in a separator roll is inhibited. In a slitting apparatus (6), a conveying direction of a first separator (12a) is changed to a first take-up roller (70U) side by a direction changing roller (68), the first separator is conveyed via a take-up assisting roller (69) which is provided between the direction changing roller and a first touch roller (81U) so as to shorten a roller-to-roller distance to the first touch roller, and the first separator which is being wound is pressed onto a take-up surface by the first touch roller.

The invention relates to a method for monitoring the condition of a continuous element (44) moving in a fiber web or paper finishing machine, said monitoring being performed with a rotating machine element (41), which is equipped with a sensor assembly (24) that measures force or pressure and against which the continuous element moves. In the method, the machine element is made to rotate against the continuous element, a measurement signal (25) is generated between the machine element and the continuous element with the sensor assembly, and a cross-directional profile (21) of force or pressure generated between the machine element and the continuous element is formed from the measurement signal. Said moving continuous element is a fabric (32, 33) installed in a fabric run (22, 23) traveling via the machine element. In the method, the fabric is additionally installed in a fabric run, wherein it moves via said machine element equipped with a sensor assembly, a reference profile (35) is formed for the cross-directional profile after installing the fabric in the fabric run, the cross-directional profile formed from the measurement signal and representing force or pressure generated between the machine element and the fabric is compared with the reference profile, and information (37) is produced from the comparison for monitoring the condition of the fabric. The invention also relates to a corresponding system and a computer program product.
