A conveyor includes a first conveyance path along which a sheet is conveyed in a first direction, a second conveyance path along which the sheet is conveyed in a second direction different from the first direction, a switching part configured to switch a conveyance direction of the sheet between the first direction and the second direction, a sheet detector configured to detect the sheet at the switching part, a conveyance system driver configured to convey and stop the sheet, and circuitry configured to control the conveyance system driver to stop conveyance of the sheet in a predetermined condition, control the sheet detector to detect the sheet at the switching part, and control the switching part to switch the conveyance direction of the sheet from the first direction to the second direction when the sheet detector does not detect the sheet at the switching part.

A printing apparatus includes: a conveyor including a first pair of conveyance rollers and a second pair of conveyance rollers each configured to nip and convey a sheet; a first jam releaser configured to separate rollers of the first pair of conveyance rollers from each other; a second jam releaser configured to separate rollers of the second pair of conveyance rollers from each other; and a controller configured to control the conveyor. In stopping sheet conveyance by the conveyor upon occurrence of a failure, the controller controls the conveyor to prevent a sheet from being nipped only by the first pair of conveyance rollers prior to separation of the rollers of the first pair of conveyance rollers from each other by the first jam releaser.

In a reel-up for reeling of fiber webs, a web travelling in direction (S) is cut by two water jet nozzles moving in a transverse direction. Two cuts (C1, C2) are formed by the nozzles starting from the web edges moving to the web center where the cuts (C1, C2) cross or meet forming a V-shaped tail end (V1). After the cuts nozzle movement is stopped and after the return of the nozzles, cutting is restarted from the center toward the edges so the web W is cut by two cuts (C3, C4) forming a substantially V-shaped beginning end (V2) and between the cuts (C1, C2) for the tail end (V1) and the cuts (C3, C4) for the beginning end (V2) there is formed one web reject part (R) with two substantially V-shaped cuts. Cross-direction travel distance (L1, L2) of each nozzle is substantially shorter than the web width.

A base material processing apparatus includes a transport mechanism, a mark detector, and a calculating unit. The transport mechanism transports an elongated strip-shaped base material in a longitudinal direction thereof along a predetermined transport path. The mark detector acquires a detection result by detecting a mark continuously at a detecting position on the transport path. The mark is applied previously to an end of the base material in a width direction thereof. The calculating unit calculates a transport speed of the base material, the amount of positional deviation of the base material in a transport direction, and tension on the base material applied in the transport direction on the basis of the detection result and information about the mark applied previously to the base material.

A printing apparatus can be downsized while degradation in the print quality can be suppressed. To perform skew correction on a second print medium on which printing is to be performed subsequent to a first print medium, a first conveying unit disposed upstream of the printing position where the printing unit performs printing on the print medium is stopped. Then, driving and stopping of third conveying unit disposed downstream of a second conveying unit is controlled, depending on whether the first print medium after printing has already passed by the second conveying unit when the first conveying unit is stopped, the second conveying unit being driven by the same driving source as that for the first conveying unit and being disposed downstream of the printing position.

An embodiment of an assembly has a landing pad configured to receive media after the media is cut. The landing pad defines a first end adjacent a cutter, a second end opposite the first end, and a gap positioned between the first end and the second end. The assembly has an emitter, wherein the gap is configured to allow light from the emitter to pass through the gap when the media is not located on the landing pad.

In a turn-up method for a reel-up for reeling of fiber webs, a web travelling in direction (S) is cut by two water jet nozzles moving in a transverse direction in relation to the web travelling direction (S). Two cuts (C1, C2) are formed by two water jet nozzles starting from the edges of the web (W) and moving to the web center where the cuts (C1, C2) cross or meet forming a V-shaped tail end (V1). After the cuts the movement of the water jet nozzles is stopped and after the return movement of the water jet nozzles, cutting is started again from the center toward the edges so that the web W is cut by two cuts (C3, C4) and a substantially V-shaped beginning end (V2) to the web W is formed and between the cuts (C1, C2) for the tail end (V1) and the cuts (C3, C4) for the beginning end (V2) there is formed one web reject part (R) with two substantially V-shaped cuts. A turn-up device for a reel-up for reeling of fiber webs has two water jet nozzles, in which the cutting by the water jet nozzles (10,12) may be stopped between cutting of a tail end (V1) and cutting of a beginning end (V2) for a selected time for forming only, wherein there is one reject part (R) in the turn-up and the cross-direction travel distance (L1, L2) of each nozzle is substantially shorter than the width (L) of the web (W).

A sheet conveyance device includes: a container that accommodates loaded sheets; a feeding mechanism that continuously feeds the sheet from the container; a conveyance path on which the sheet is conveyed; and a pitch adjustment mechanism provided on the conveyance path and which adjusts a pitch of a preceding sheet and a subsequent sheet, wherein the pitch adjustment mechanism includes a pitch adjustment roller pair including a first pitch adjustment roller and a second pitch adjustment roller that sandwich the conveyance path and are in pressure contact with each other, the first pitch adjustment roller is driven and rotated in a direction following a sheet conveying direction, the second pitch adjustment roller is driven and rotated in the direction following a sheet conveying direction, and the second pitch adjustment roller is connected to a drive shaft that drives the second pitch adjustment roller via a one-way clutch.
