A method for transferring a sheet in a sheet transport assembly from a supplying conveyor to a receiving conveyor. The method includes arranging a contact side of a sheet in contact with a transport belt of the supplying conveyor, advancing the sheet on the transport belt in a transport direction along a process unit, which applies a process to a process side of the sheet opposite to the contact side, and to a transfer area where the sheet is transferred to a receiving conveyor. To correct for curl deformation of the sheet, air flow is directed onto the process side of sheet, which urges the sheet towards a supporting element. The air flow is controlled in response to a curl deformation behavior of the sheet.

An apparatus for forming and sorting informational items comprises a folding unit, a conveyor belt, a camera, a controller, and a diverter assembly. The folding unit forms a folded article from a sheet of paper. The conveyor belt transports the folded article. The camera captures an image of the folded article as it passes by the camera. The controller receives and processes the image, and the diverter assembly causes the folded article to move off of the conveyor belt when the controller determines that the folded article fails to satisfy at least one predetermined criteria.

A paper feeding device for rotating a roll paper forward and backward to feed the roll paper includes a roller, a sensor, a support, and processing circuitry. The sensor detects a level difference at an end of the roll paper. On the supports, the sensor and the roller are arranged at positions offset from each other in a circumferential direction of the roll paper with respect to a center of the roll paper. The support supports the sensor and the roller to abut on a surface of the roll paper. The processing circuitry controls rotation of the roll paper based on a sensor signal output from the sensor. The processing circuitry causes the roll paper to rotate in a paper feeding direction, and compares an inclination of a change in the sensor signal with a threshold value to detect a paper tube of the roll paper.

A method for splicing two sheets of material containing alkaloids is provided, the method including: providing a first sheet of material containing alkaloids wound in a first bobbin; providing a second sheet of material containing alkaloids wound in a second bobbin; unwinding the first sheet wound in the first bobbin; evaluating one or more of the following parameters of the unwound first sheet: moisture, thickness, width, stickiness, and presence or absence of holes or tears; and depending on a value of the evaluated one or more parameters, unwinding the second sheet wound in the second bobbin, and splicing the first sheet and the second sheet. A system for splicing two sheets of material containing alkaloids is also provided.

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).

A foil transfer film cartridge includes a supply reel on which a foil film having a widthwise dimension of a first width is wound, and a supply shaft longer in a widthwise direction of the foil film than the first width. The supply shaft is configured to support the supply reel in a manner that allows the supply reel to move in the widthwise direction between a first position and a second position different from the first position.

A method of making adhesive tape has a step of first feeding a textile substrate band formed of thermoplastic fibers or filaments from a supply roll in a longitudinal direction. Then at least one longitudinally extending track where the fibers or filaments are melted together and a thickness of the band is reduced is formed in the band. The band formed with the track is thereafter cut into longitudinal strips by longitudinally severing the band at the track with a longitudinal slitter having at least one blade.
