Abstract: A coreless paper roll rewinding machine without a winding assisting plate comprises a rewinding upper roller (1) and a rewinding lower roller (2) that are parallel with each other. Paper (3) is wound on the rewinding upper roller (1) and passes through a roller gap between the rewinding upper roller (1) and the rewinding lower roller (2). A plurality of airflow channels (4) are formed in a roller body of the rewinding lower roller (2), and each of the air flow channels (4) is interconnected with a set of air suction holes (5) on the surface of the roller body. An air suction cover (6) provided with an exhaust opening is arranged close to the end of the rewinding roller (2). When one set of air suction holes (5) on the surface of the rewinding lower roller (2) is close to the roller gap, one of the air flow channels (4) interconnected with the set of air suction holes is rotated to a region interconnected with the exhaust opening of the air suction cover (6). When the set of air suction holes (5) on the surface of the rewinding lower roller (2) is far away from the roller gap, the corresponding air flow channel (4) is rotated to a region where it deviates from the exhaust opening. This coreless paper roll rewinding machine has high winding reliability, stable rewinding function and uniform roll compactness, and can prevent the indentation on the surface of the paper roll.

Abstract: A plate configured to contact a web includes a first region having a first characteristic and a second region having a second characteristic different than the first characteristic. The plate has a substantially arcuate wall with an inner surface and an outer surface. A plurality of vacuum holes extends between the inner and outer surfaces and are configured to be in fluid communication with a vacuum source. A vacuum region is adapted to contact the first region of the web and a reduced-vacuum region is adapted to receive the second region of the web. The plurality of vacuum holes are configured such that, when attached to the vacuum source, a vacuum pressure at the vacuum region is greater than a pressure at the reduced-vacuum region so that the first region of the web is held against the plate with a greater force than the second region.

Abstract: A sheet supply system, for use in supplying overlapped sheets to an interfolder, includes a bed roll on which a web is cut into successive sheets. The sheets are supplied to a sheet supply passage leading to retard rolls, which overlap the sheets within the supply passage. The trailing portion of each downstream sheet bulges outwardly as the sheet is supplied to the supply passage. An air tube directs pressurized air into a volume within which the bulge in the downstream sheet is formed. The pressurized air prevents the leading portion of the upstream sheet from being drawn outwardly along with the trailing area of the downstream sheet, by counteracting a vacuum that results from outward movement of the trailing portion of the downstream sheet after it is released from the bed roll. The pressurized air also maintains the upstream sheet in engagement with stripper fingers that guide the sheets through the sheet supply passage, and ensures separation between the trailing end of the downstream sheet and the leading end of the upstream sheet.

Abstract: The present invention provides a device for securely holding stacked bank notes in a bank note stacker box. The device is to be assembled in an automatic money depositing and disbursing machine, and comprises a combination of a stopper and a push cover having an operation plate fitted with a frictional member. The stopper is swingably supported by the box to be held normally at the position to constrain the fore edges of the stacked bank notes, to be swung to the position to release the fore edges of the bank notes at the commencement of the operation of sucking and pulling out the notes from the box, to be restored to the normal constraining position to prevent the remaining notes from being pulled out of the box at the termination of the operation of sucking and pulling out the notes, and to be held at a position to scrape off the bank notes conveyed by and accumulating wheel while being inserted below respective paddles of the accumulating wheel to let them fall down into the box during the operation of accumulating and stacking bank notes into the box. The push cover has the operation plate adapted to be set to the closed position to push the aft end portion of the stacked notes during the operation of sucking and pulling out the notes from the box to ensure separation of the sucked uppermost note by the action of the fitted frictional member, and adapted to be set to the open position during the operation of accumulating and stacking bank notes. Further proposed is a front cover which is co-operatively associated with the stopper such that it locks the fore end portion of the stopper to prevent the same from opening when the box is disassembled from the machine body of the automatic money depositing and disbursing machine.
