Provided are an image forming apparatus and an image forming method capable of coping with a medium exceeding a transport limit of a pair of rollers in image formation in which the medium is transported with the medium interposed between the pair of rollers. In a case where a medium exceeding a transport limit of first transport means to which medium transport using a first roller and a second roller is applied is used, second transport means is used to assist in the medium transport performed by the first transport means. The driving of second driving means for driving the second transport means is controlled using a driving signal applied to the driving control of the first driving means for driving the first transport means. Medium transport in which synchronization is taken between the first transport means and the second transport means is realized.

A device for dispensing active ingredient-containing or active ingredient-carrying strips, including a housing in which a coil chamber for receiving an active ingredient-containing or active ingredient-carrying band is arranged, in which a gear transmission with a driven roller for conveying the band is mounted, and in which a separating device for separating the strips from the band is arranged. A method for dispensing active ingredient-containing or active ingredient carrying strips using such a device is also disclosed. An active ingredient-containing or active ingredient-carrying band is arranged between the driven roller and the pressure roller. A shift clutch transmission having a manually actuatable trigger element is arranged upstream of the gear transmission. The driven roller can be driven in incremental strips by the shift clutch transmission. A device and method is disclosed for dispensing active ingredient-containing or active ingredient-carrying strips with a largely equal dosage are developed.

The invention provides a tape dispenser for liquid-activated tape which can be used in handheld or table-top modes. A main body of the dispenser has a rear section for holding a tape reel, and a front section which houses a drive section, a cutter, an activation section, and a main reservoir located below the activation section for holding liquid to activate the tape. A pump is arranged to pump liquid from the main reservoir to the activation section, where in use liquid is applied to the tape to activate it, and means are provided to allow liquid that overflows from the activation section to return to the main reservoir, preferably under gravity. The tape reel is supported by a drum in the rear section, and the drum can be slid out of the rear section to allow the tape reel to be replaced.

A sheet conveyance apparatus includes a first conveyance portion configured to convey a sheet, a second conveyance portion configured to convey the sheet, the second conveyance portion including an abutment portion configured to form a loop on the sheet by being abutted against a leading edge of a sheet conveyed by the first conveyance portion, a curved guide portion, which is curved, configured to guide the sheet conveyed by the first conveyance portion to the second conveyance portion, and a rotary member arranged downstream of the first conveyance portion and upstream of the second conveyance portion in a sheet conveyance direction, and configured to be driven to rotate by a surface of the sheet that is guided by the curved guide portion, the surface sliding against the curved guide portion.

A device for dispensing active ingredient-containing or active ingredient-carrying strips, including a housing in which a coil chamber for receiving an active ingredient-containing or active ingredient-carrying band is arranged, in which a gear transmission with a driven roller for conveying the band is mounted, and in which a separating device for separating the strips from the band is arranged. A method for dispensing active ingredient-containing or active ingredient carrying strips using such a device is also disclosed. An active ingredient-containing or active ingredient-carrying band is arranged between the driven roller and the pressure roller. A shift clutch transmission having a manually actuatable trigger element is arranged upstream of the gear transmission. The driven roller can be driven in incremental strips by the shift clutch transmission. A device and method is disclosed for dispensing active ingredient-containing or active ingredient-carrying strips with a largely equal dosage are developed.

A system and method for advancing sticky media through printers includes one or more feed rollers comprised of a grit roller. The grit roller contacts an adhesive side of liner-less label stock removed from a roll or stack for printing. The grit roller works cooperatively with an opposing, counter-rotating roller to remove the label stock from the roll and feed it to a printer.

A sheet separation device includes a sheet separator and a conveyor. The sheet separator separates a non-bonding portion of a two-ply sheet in which two sheets are overlapped and bonded together at a bonding portion of the two-ply sheet. The conveyor conveys the two-ply sheet toward the sheet separator while bending the two-ply sheet in a direction that intersects a conveyance direction of the two-ply sheet.

The present invention pertains to a device for producing printed products comprising an arrangement of cooperating rollers that are arranged parallel to one another, wherein at least the gap width between the rollers of one roller pair is adjustable. For this purpose, one roller of the pair is pivotably mounted by means of a pivot arm, wherein a driver arranged on the pivot arm displaces a linearly movable reference element by means of a sliding block guide such that the position of this reference element corresponds to the adjusted gap width. The sliding block guide is preferably realized in such a way that the gap width and the position of the reference element are proportionally correlated.

Provided is a control unit of a conveying apparatus, the conveying apparatus including: a conveying unit that conveys recording paper along a conveying path; and an imaging unit that images the recording paper and an object not conveyed by the conveying unit, wherein the control unit acquires actual conveyance information of the recording paper from image information of the recording paper imaged by the imaging unit and image information of the object imaged by the imaging unit.

A method includes, a first step of starting rotation of a rotating axle, which is configured to detachably support a web, in a direction in which the web is wounded onto the rotating axle, a second step of detecting a tension applied to the web after the first step, a third step of performing open loop control on torque applied to the rotating axle until the tension greater than a designated value is detected with the second step, and a fourth step of performing feedback control on the torque applied to the rotating axle based on the detection value of the tension applied to the web after the tension greater than the designated value is detected with the second step.
