A winding condition generating apparatus includes: an input unit; an output unit; and a condition calculation unit. A winding condition calculation unit includes a learning model created by machine learning using a combination of a winding parameter and a winding condition in producing a wound web that satisfies a target winding quality as training data, and calculates a winding condition of a new wound web using the learning model, from a winding parameter of a new wound web input through the input unit. The output unit outputs the winding condition. The winding parameter includes a web width, a web transport velocity, and a web winding length. The winding condition includes a tension of the web at the start of winding and a tension of the web at the end of winding.

A packaged flexible film is described. The packaged flexible film includes (i) a cylindrical core having an outer surface; (ii) a supply of flexible film wound about the core with a leading edge adjacent the outer surface and forming a connection ridge along the outer surface; and (iii) a cover strip comprising a compressed compressible cover material covering said connection ridge. Also described are a packaging system for flexible film and a multilayer flexible film packaging tape.

A control system for a converting line has a sensor configured to sense a distance between the sensor and a surface of a roll of web material as the roll of web material is unwound from an unwinder and directed to the converting line. The controller is configured to: (i) determine a diameter measurement of the roll as the roll rotates based upon the sensor signals; (ii) store a plurality of data structures in a memory of a controller of a control system wherein the data structures comprise a plurality of data items associated together as the diameter measurements of the roll of the web material; (iii) process by a statistical regression analysis the data structures associated with the diameter; and (iv) generate signals for controlling the converting line based upon the processed diameter measurements.

Machine for controlling the shape of a reel of web product, comprising a pick-up zone for at least one reel to be evaluated, a moving apparatus of said at least one reel from said pick-up zone to an unloading zone, and an evaluation apparatus of at least the outer diameter of the reel, configured to act between said pick-up zone and said unloading zone.

A method for reducing the effects of variations in an unwinding, convolutely wound roll of web material is disclosed. The method utilizes the steps of: a. selecting a reference objective relating to a downstream operation, b. choosing at least one feedback device correlated to the reference objective, c. collecting process data from the at least one feedback device at different positions within a time-varying operation cycle for at least one operation cycle at a learning speed, d. calculating an error as the difference between the collected process data from step (c) and a reference signal related to the selected reference objective, e. generating a correction signal based upon the calculated error from step (d) and, f. applying the correction signal to the actuator during a succeeding time-varying operation cycle.

A stacking apparatus for value documents, having a stack deposit device and a braking device which is arranged along the transport path of the value documents immediately before the stack deposit device. On the transport shaft of the braking device at least one driving roller is firmly mounted and at least one roller rotatably supported on the transport shaft. At least one cam roller is firmly mounted on a braking shaft of the braking device and at least one eccentric roller. By a rotation of the braking shaft, the eccentric roller can electively be brought in engagement with the opposing driving roller so that a value document becomes clamped between these, or be brought out of engagement with the opposing driving roller, so that the value document is no longer clamped between these, but rather is brakable by the engagement between the cam roller and the rotatably supported roller.

A banknote temporary storage device includes: a timing unit, configured to obtain a time period between a time when the front end of a banknote enters into a first sensor and a time when the back end of the banknote leaves the first sensor; a calculating unit, configured to calculate a width of the banknote based on the time period, calculate a bump radius based on the width, and determine a condition of generating a bump on the storage coiling block; a detecting unit, configured to detect whether the condition of generating a bump on the storage coiling block is met, based on a real-time radius; and an interval control unit, configured to change an interval between banknotes on the storage coiling block in a pre-set control manner to eliminate a bump, in a case that the condition is met.

Provided are a roller assembly, a battery cell manufacturing device, and an adjustment method of a roller, which relates to the field of battery manufacturing technology. The roller assembly includes a holder, a roller, and a first adjusting member. The roller is rotatably mounted on the holder. The first adjusting member is rotatably mounted on the holder, and one end of the roller is rotatably connected to the first adjusting member. A rotation axis of the roller does not coincide with a rotation axis of the first adjusting member. One end of the roller is rotatably mounted on the holder through the first adjusting member. The rotation axis of the first adjusting member does not coincide with the rotation axis of the roller, and therefore, rotation of the first adjusting member is capable of driving a corresponding end of the roller to rotate, thereby adjusting an extension direction of the roller.
