A device and a method for feeding a sheet material are provided. A conveying machine is disposed above a holding machine. A sensor detects a lateral position of a rubber sheet fed from the holding machine. At a position between a grip position below the conveying machine and a release position at an upstream side in a conveying direction above the conveying machine, a leading edge of the rubber sheet is gripped by a gripping machine. The gripping machine is revolved and moved to the release position using, as a revolution center, a position in a vertical direction midway between the grip position and the release position. The leading edge being released is pressed against a placement surface of the conveying machine by a pressing portion. The rubber sheet is placed on the placement surface and conveyed to a downstream side in the conveying direction by the conveying machine.

The invention relates to a monitoring method (100) for monitoring an unwinding process of an unwinding device (2), comprising the following steps: at least partially unwinding (101) a web material (11) from a reel (10), detecting (102) at least one irregularity (12) of the web material (11) and/or the unwinding process. Furthermore, the invention relates to an unwinding device (2) for performing an unwinding process as well as an unwinding system (5) for performing an unwinding process.

Provided are systems and methods for identifying, isolating, and/or aligning sheets. An identification system can facilitate accurate identification of a sheet by (i) vacating one or more components of the system that are not the sheet from a zone of detection, and/or (ii) determining a reference axis of the sheet. An isolation system can facilitate accurate isolation of a sheet by (i) providing targeted air flow, and/or (ii) introducing a wave into the sheet. Identification systems and/or isolation systems described herein may facilitate isolation of sheets that were previously fastened together by one or more fasteners. An alignment system can facilitate accurate alignment of a first sheet at an upstream location relative to a second sheet at a downstream location via machine learning.

A method for automatically replacing reels in an unwinding assembly capable of carrying out the handling operations of the reels, as well as preparing and joining the tail of the web of the finished reel with the head of the web of the new reel in a simple, efficient way, reducing the risk of malfunctions and maintaining the correct orientation of the new web as that of the finished web.

This disclosure relates to a banknote validator. The banknote validator comprises a banknote path disposed within an interior of the banknote validator, the banknote path including a banknote imaging zone, one or more banknote edge detection surfaces each configured to provide images of edges of a banknote in the banknote path, a banknote imaging sensor configured to provide an image of at least one portion of the banknote imaging zone, and an image sensor configured to capture the images of the edges of the banknote provided by the one or more banknote edge detection surfaces, and capture the image of the at least one portion of the banknote imaging zone provided by the banknote imaging sensor.

According to one embodiment, a paper sheet processing apparatus includes a conveyance device with a conveyor belt, and an inspection device configured to inspect a paper sheet conveyed by the conveyor belt. The inspection device includes an image detection device configured to capture an image of the paper sheet and the conveyor belt and obtain an image of the paper sheet and the conveyor belt, an image processing device configured to detect a degradation level of the conveyor belt based on an belt image of the conveyor belt, and a controller configured to transmit information encouraging replacement of the conveyor belt to a monitor.

Apparatus and methods are provided to minimize waste and improve quality and production in web processing operations. The apparatus and methods provide defect detection in deposition of acquisition material, which on current machines frequently flips and is difficult to detect when it has flipped causing manufacturers to scrap thousands of products. Using the present invention, defects are able to be detected by discerning a difference in the appearance from side to side with a vision camera, and an acquisition inverter can flip the material to a correct orientation.

Rewinder for making paper logs, including a winding station with a first winding roller and a second winding roller delimiting a nip and a third winding roller downstream of the other rollers. The rewinder includes optical elements for detecting, at a predetermined time, an actual position of each log in said winding station and an electronic unit connected to the optical elements and programmed to compare the actual position with a theoretical position of the log at the time, the electronic unit being connected to at least one motor driving the rollers and programmed to modify the speed of the at least one motor when a deviation between the actual and theoretical positions exceeds a pre-established value, the electronic unit being also programmed to operate said optical elements at the time.

A printing device is provided comprising a camera to capture an image of at least a portion of a print substrate; a controller to determine a location of a portion of a side edge of the substrate from the image to determine a distance of the print substrate from a predetermined location; and adjustment apparatus to adjust the entire substrate laterally, relative to the direction of transport of the substrate, based on the determined location.

A bag-making and packaging machine has a film supply unit that supplies film to a bag-making and packaging unit. The film supply unit has a film conveyance mechanism that conveys a first film so that a trailing end portion of the first film heads toward a film splicing position for splicing to a leading end portion of a second film, a first sensor detecting a mark on the first film, a second sensor detecting the mark at downstream, and a controller for the film conveyance mechanism. The controller judges, based on detection of the second sensor, that the trailing end portion of the first film has reached the splicing position and stops conveyance of the first film. The controller controls the conveyance mechanism so that the conveyance speed of the first film before the detection of the mark by the first sensor is faster than the speed after the detection.
