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.

A system for in-line treatment of thread for use with a thread consuming device is provided. The system comprises at least one treatment unit being configured to dispense one or more coating substances onto the at least one thread when activated and a thread speed sensor being driven by the motion of the at least one thread. A method is further provided.

A sensor unit includes a light-emitting unit including a light-emitting element configured to emit light, a light-receiving unit including a light-receiving element configured to receive the light emitted from the light-emitting element, a flag configured to pass through a space between the light-emitting unit and the light-receiving unit, and a board, wherein a cutout or a hole is formed in the board, wherein the light-emitting unit and the light-receiving unit are mounted on the mounting surface of the board so that the light-emitting element and the light-receiving element face each other, and the light emitted from the light-emitting element travels straight along the mounting surface of the board over the cutout or the hole, and wherein the flag moves in a direction intersecting the mounting surface of the board and enters the cutout or the hole, thereby blocking the light traveling from the light-emitting element to the light-receiving element.

A system for in-line treatment of thread for use with a thread consuming device is provided. The system comprises at least one treatment unit being configured to dispense one or more coating substances onto the at least one thread when activated and a thread speed sensor being driven by the motion of the at least one thread. A method is further provided.

A medium conveying apparatus includes a first optical sensor located on an upper part of the housing and in a central part of the housing in a direction perpendicular to a medium conveying direction, a second optical sensor located on an upper part of the housing and on a side of the first optical sensor in the direction perpendicular to the medium conveying direction, and a processor to detect a folding of a medium based on the first signal or the second signal, and stop feeding of the medium by the feed roller in accordance with a detection result of the folding of the medium. The first light emitter emits first light toward a downstream side of the medium in the medium conveying direction, and the second light emitter emits second light toward an upstream side of the medium in the medium conveying direction.

An electrode sheet transporting apparatus includes a first transporting conveyor having a supply area receiving an electrode sheet, the first transporting conveyor being configured to transport the electrode sheet in a first direction, a supply member configured to supply the electrode sheet to the supply area, a lighting member configured to radiate light to the supply area, and a sensing member facing the lighting member, the sensing member being configured to detect light reflected from the electrode sheet on the supply area.

An apparatus for removing wrinkles from a sheet material, includes: an expander roll that rotates in a bent state with respect to a rotation axis bent to straighten and remove wrinkles formed in a sheet material being transferred to be wrinkle-removed; a roll bender that generates a bending moment to bend the expander roll; a roll rotator that rotates the expander roll; a roll controller that controls the operation of the roll bender and the roll rotator; a vision camera that photographs one surface of the sheet material being wrinkle-removed, so as to generate an input image; and a wrinkle detection module that detects wrinkles in the sheet material to be detected, using the input image.
