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.

The disclosure generally relates to a looped pile film roll core used for winding a polymeric film, a method of winding film on the looped pile film roll core, and a roll of film that includes the looped pile film roll core. The disclosure describes an article and a process to reduce the core impressions created by the starting end of a web on the adjacent web layers next to the core. In one particular embodiment, the present disclosure can lead to a reduction in the amount and severity of such core impressions on a wound polymeric film, by reducing the amount of stress in adjacent layers of wound web.

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 process for improving the convertability of parent rolls of convolutely wound web materials is disclosed.

A winding core covering (10) comprising a backing (45), the backing (45) having an adhesive layer (40) and a support layer (30) in contact with the adhesive layer (40), and a web contact layer (20) in contact with the backing (45), the web contact layer (20) including a thermoplastic polymer, where the outer surface (27) of the web contact layer (20) has a structured surface comprising a plurality of protrusions (25) having an average height (H) of 50 m to 600 m. A winding core (41) including the disclosed winding core covering (10).

The invention relates to a method for winding up a web of material with an apparatus including one winding-up space having a winding center; means for conveying and/or manipulating the web of material prior to and/or during winding-up; and including the following steps: operating the apparatus; monitoring the web of material and/or the resulting wound roll by means of at least one image capturing device for obtaining at least one current state of the web of material and/or of the wound roll; comparing at least one actual state to at least one target state and corresponding to the actual state, and determining at least one deviation of the actual state from the corresponding target state; if the deviation exceeds/falls below at least one predetermined limit value, performing a correction of at least one operating parameter of the apparatus which operating parameter is at least a contributing factor for the deviation.

Provided is a measurement device (10) for detecting local thickenings in a film web (20), more particularly an extrusion and/or coextrusion film, having a first roll (14) for rolling on the film web (20) that can be moved along, a second roll (18) that can be supported indirectly above the film web (20) on the first roll (14) for rolling on the film web (20) that can be moved along, wherein the second roll (18) is resiliently guided in the thickness direction of the film web (20) that can be moved along, more particularly in the vertical direction, and at least one distance sensor (24) that is stationary with respect to the first roll (14) and/or to the film web (20) that can be moved along, for detecting a distance of the second roll (18). The second roll (18), which can be displaced from a local thickening of the film web (20) in the thickness direction of the film web (20), makes it possible to quickly and easily detect local thickenings in a film web (20).

The present invention relates to a system (200) and computer implemented method for monitoring the performance of at least one winding spool (120) in the reel section (100) of a paper machine, by detecting a unique identification code, ID, associated with the winding spool (120) from a marker (130) on the winding spool (120); identifying the winding spool (120) based on the unique identification code, ID; determining at least one winding spool performance parameter for the identified winding spool (120) based on measurements from at least one sensor (160); and determining if there is a failure of the performance of the identified winding spool (120) based on if the determined at least one winding spool performance parameter fulfils a requirement indicative of failure of the performance of the winding spool (120). The invention further includes a computer program comprising software for executing the method, a non-volatile data carrier, and a paper machine comprising the system.

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.
