A guide film supply mechanism feeds a guide film toward a winding mechanism. The guide film is a film in which a pair of supports, which is long in the longitudinal direction of a base film and is thicker than a product film, is disposed on both side portions of the upper surface of the base film that is formed to have a width larger than the width of the product film. A product film supply mechanism feeds the product film toward the upper surface of the guide film. The winding mechanism forms a film roll by winding the product film for each guide film. The tension of the product film is set to be smaller than the tension of the guide film.

A transportation path changing device (1) of the invention is a transportation path changing device that changes a transportation path of a continuous sheet-like object (3) that is being transported. The device includes: an oscillating section (2) that oscillates in an intersecting direction Y intersecting with a flow direction X of the transported object, and that increases/decreases the length of the transportation path of the transported object (3); a first moving means (6) that is connected to the oscillating section (2), and that moves the oscillating section (2) in the intersecting direction Y; a second moving means (7) that moves a portion or the entirety of the first moving means (6) in the intersecting direction Y; and a control section (9) that controls the first moving means (6) and the second moving means (7).

A roll-up apparatus for rolling up a continuous sheet into a roll shape, comprises a tension generation unit configured to generate a changeable tension to the continuous sheet; and a control unit configured to control the tension generation unit based on a roll-up condition of the continuous sheet.

Apparatus for dispensing paper toweling from a roll of paper toweling includes a rotary damper resisting formation of overspin slack in the paper toweling resulting from a pulling force applied to the paper toweling. Control mechanism changes the rotary damper from an operative condition to an inoperative condition responsive to reduction of the diameter of the roll of paper toweling.

An apparatus (un-interleaver) for unwinding a roll of material interleaved with another material, and for separating the materials, includes a first platform, a second platform, a tension-sensor, an edge-sensor, and a controller. The controller monitors signals generated by the tension sensor and the edge sensor, and in response to the signals: a) causes the speed at which the second platform rotates to change to maintain a predetermined tension in the second material as the second material travels from the first platform toward the second platform, and b) causes the second platform to move relative to the first platform to align the edge of the second material traveling toward the roll of second material with the edge of the second material in the roll.

A web transport system for transporting a web of media along a web-transport path including a fluid bar for guiding the web of media, and a scavenger blade positioned downstream of the fluid bar. A liquid is pumped through holes in an exterior bearing surface of the fluid bar, thereby pushing the web of media away from the fluid bar. The scavenger bar includes a blade edge facing the first surface of the web of media, the blade edge being spaced apart from the first surface of the web of media by a gap distance. The scavenger blade removes at least some liquid from the first surface of the web of media as it passes by the scavenger blade, thereby reducing the amount of liquid that is carried along to portions of the web-transport path that are downstream of the scavenger blade.

A roll-to-roll continuous coater for CCM preparation, and a coiled material connection method are provided. The coater has a coiled material connection mechanism that includes an upper rack (2) and a lower rack (3). A vacuum suction plate I (2-3) provided with a driving device for achieving displacement and a vacuum suction plate II (3-1) provided with a solid glue spraying device (3-3) are respectively disposed on the bottom of the upper rack (2) and the top of the lower rack (3). An optical fiber sensor I (2-4) and an optical fiber sensor II (3-2) are respectively disposed in the vacuum suction plate I (2-3) and the vacuum suction plate II (3-1). A tension detection device (4) is disposed between the lower rack (3) and a driving roller assembly (1).

The rewinding machine (1) includes: a winding station (3) with winding members (5, 7) operated by winding motors (8.1, 8.2); an unwinder (31.1, 31.2) with an unwinding member (35.1, 35.2) operated by at least one unwinding motor (38.1, 38.2); a guide roller (43.1, 43.2) along a feed path (P) of the web material (N, N2). There is associated with the guide roller (43.1,43.2) at least one load sensor (42.1, 42.2), adapted to detect a parameter proportional to the tension of the web material (N; N2) guided around the guide roller (43.1,43.2). There is also provided a control unit (71) adapted to modulate a difference in speed between the winding members (5, 7) and the unwinding member (35.1,35.2) as a function of a signal corning from the load sensor (42.1,42.2).
