A belt drive mechanism (16) has pulleys (26a to 26d, 28a to 28b), and endless belts (32a to 32d) wound around these pulleys, and is arranged above the table (12) and the guide member (14) so as to stride over the table (12) and the guide member (14). A first opening portion is formed on a bottom portion of the belt drive mechanism (16) to generate an upward suction force. A second opening portion is formed on the upper surface of the guide member (14) to generate a downward suction force. A magnitude of the suction force generated in the first opening portion exceeds a magnitude of the suction force generated in the second opening portion.

A film feeding apparatus and a control method thereof are provided. The film feeding apparatus comprises a delivery head. A surface of the delivery head has an air suction region and an air blowing region, and the air suction region and the air blowing region respectively include an air hole; and by cooperation of air suctioning through the air hole of the air suction region and air blowing through the air hole of the air blowing region, a film is kept nearby the delivery head in a non-contact manner in the case that the delivery head adsorbs the film.

A raw material supply device for a separator of a secondary battery includes a conveyor for causing an end portion of the supplied raw material to move to an end portion of the existing raw material; and a bonding unit for bonding the end portion of the supplied raw material and the end portion of the existing raw material. The raw material supply device may automatically bond the existing raw material and the supplied raw material by using ultrasonic waves with respect to the raw material for the separator of the secondary battery in the form of a roll.

A roll replacing device includes an unwinding member, a roll replacing member and a cutting member. The roll replacing member includes a first roll replacing mechanism and a second roll replacing mechanism arranged opposite to each other. The cutting member can cut off a first strip or a second strip pressed between the first roll replacing mechanism and the second roll replacing mechanism.

A sheet printer includes a sheet conveyor assembly including a first conveyor with a first holding device configured for exerting a holding force on a sheet proportional to a coverage of the sheet on the first conveyor and a second conveyor upstream of the first conveyor including a second holding device configured for holding and releasing the sheet, a print head assembly positioned over the first conveyor, a detector assembly for sensing the transport of the first conveyor, a controller storing on its memory a sheet media catalogue and configured to control a release timing of the second holding device for releasing the sheet partially engaged by the first conveyor based on a media type parameter selected from the media catalogue and to control the print head assembly to commence printing the sheet based on transport information from the detector assembly.

A conveyor for conveying good. According to one embodiment the conveyor includes a holding unit for holding or releasing the goods with respect to a conveyor belt. The holding unit includes vacuum holding means and magnetic holding means. The magnetic holding means includes at least one movable element that comprises at least one magnet or has a magnet attached thereto. The movable element is able to deactivate the magnetic holding means by distancing the magnet from the conveyor belt, and is also able to be arrange in a closed position in which the movable element blocks a vacuum conduit extending through the conveyor belt.

Described is a device for automatically connecting a continuously manufactured material, the device including a fixed roller rotatably fixed, the fixed roller being rotatable about the shaft of the fixed roller, a swing roller connected to the fixed roller and rotatable by the rotation of the fixed roller, the swing roller being rotatable about the shaft of the swing roller, and a holder plate, connected to the fixed roller, rotatable together with the fixed roller, and configured to hold the material. Also described are a system and a method for manufacturing a material.

A web transport assembly is provided for transporting a web along a processing unit for processing the web, the web transport assembly comprising: a transport device arranged for moving the web in a transport direction through a transport path along the processing unit, the transport device being arranged downstream of the processing unit relative to the transport direction; and a friction-based tensioning device arranged upstream of the processing unit relative to the transport direction; wherein the friction-based tensioning device comprises a guiding surface for guiding the web towards the processing unit and a plurality of suction holes distributed over the guiding surface for providing a suction force to a contact side of the web, the plurality of suction holes being arranged in fluid communication to a suction source, which generates the suction force, wherein the guiding surface is configured to exert a friction force on the web in response to the suction force provided to the contact side of the web; and wherein the friction-based tensioning device is configured for controlling a tension of the web between the guiding surface and the transport device.

Disclosed is an image forming apparatus including a conveyance section, an attraction section, an image forming section, and a hardware processor. The conveyance section includes conveyance surfaces on each of which a sheet can be placed and that conveys the sheet placed thereon. The attraction section that attracts the sheet onto the conveyance surfaces by sucking air from suction holes. The image forming section forms an image on the sheet. When a decrease of an attraction force by the attraction section is caused in executing a print job, the hardware processor causes one or more of the conveyance surfaces to suck and convey a non-print job sheet and then causes the one or more of the conveyance surfaces to consecutively suck and convey a print job sheet, and does not perform image formation on the non-print job sheet and performs the image formation on the print job sheet.
