A sheet conveyance apparatus includes a conveyance guide configured to guide a sheet along a conveyance center line extending in a conveyance direction, a reference member including an abutment surface, a conveyance unit configured to convey the sheet while abutting a first edge of the sheet against the abutment surface, a detection unit configured to detect a first angle formed between the first edge of the sheet and a second edge adjacent to the first edge, a moving unit configured to move the reference member so as to change a second angle formed between the abutment surface and the conveyance center line, and a control unit configured to perform a movement process in which the moving unit moves the reference member such that, when the first angle is referred to as α, the second angle becomes an absolute value of a difference 90 degrees minus α.

There is described a web alignment device for aligning a web comprising an engagement surface for supporting the web, a clamp assembly for clamping the web on at least a clamp portion of the engagement surface, an alignment control assembly for controlling a correct alignment of the web. The alignment control assembly comprises a control unit for generating a trigger signal if the web is correctly aligned, a first sensor device for detecting and/or determining a desired position of a first section of the web and to send at least a first signal to the control unit if the first section is positioned in the desired position, and a second sensor device for detecting and/or determining a desired position of a second section of the web and to send a second signal to the control unit if the second section is positioned in the desired position.

A tape applicator configured for applying a tape to a carton (e.g., for sealing and/or assembling the carton). The tape applicator may include an edge folder assembly having an edge folder roller operatively coupled to a support member that allows the edge folder roller to rotate around the support member. The edge folder assembly may also include an alignment assembly (e.g., a self-alignment assembly) that allows the edge folder roller to move axially along the support member. The alignment assembly may comprise one or more biasing members (e.g., springs, or the like) and/or one or more restraining members (e.g., washers, or the like) to aid in allowing the edge folder roller to rotate and/or move axially with respect to the one or more support members in order to account for shifting of the tape transversely through the tape applicator.

A method for manufacturing an electrode assembly includes a first combination step of combining a first electrode with an upper portion of a first separator to form a first combination, and a second combination step of combining the first combination so that a second electrode faces the first electrode with the first separator therebetween after the second electrode is stacked on a second separator, wherein the first combination step comprises a first electrode cutting process of moving the first electrode in an X-axis direction that is a progress direction to cut the first electrode to a predetermined size, a first electrode transfer process of transferring the cut first electrode, a first first-electrode position detection process of measuring a Y-axis position of the first electrode, a first separator meandering correction process of moving the first separator, a first stacking process of stacking the first electrode on the first separator.

An image forming apparatus configured to form images on both sides of a sheet, includes an image forming unit, which is configured to form an image on an image bearing member, and a sheet conveying device, which is configured to move the sheet being conveyed toward a width direction, which is orthogonal to a conveyance direction. After the formed image is transferred onto a first surface of the sheet, the image forming apparatus inverts and conveys the sheet to transfer an image onto a second surface. Moreover, a side edge position of the sheet in the width direction is detected during conveyance for the transferring onto each of the first surface and the second surface, and an image writing start position for the image forming unit is determined based on a result of the detection to store a result of the determination in a memory.

An image forming apparatus includes an image forming unit, a reversing roller pair, a moving unit, and an obtaining unit. The image forming unit forms an image on a sheet. The reversing roller pair nips the sheet having the image, rotates in a first direction, and then rotate in a second direction and conveys the sheet. The moving unit moves the reversing roller pair. The obtaining unit obtains the sheet length. If a first sheet having a first length is reversed and conveyed, the moving unit moves the reversing roller pair conveying the first sheet in the width direction by a first moving amount. If a second sheet having a second length greater than the first length is reversed and conveyed, the moving unit moves the reversing roller pair conveying the second sheet in the width direction by a second moving amount smaller than the first moving amount.

An image forming apparatus includes a sheet conveyance portion, a recording portion, a sheet detection portion, and a control portion. In a duplex printing including a first and a second process of printing on a first surface and a second surface of the sheet, in the first process, the control portion calculates a center position of the sheet based on an edge position of the sheet on one side in the width direction and size information of the sheet, prints a first image on the first surface such that the first image is centered on the center position calculated, and prints a reference marker on the first surface. In the second process, the control portion calculates a correction magnification ratio based on a difference between a reading position and the printing position of the reference marker, and corrects a size and a printing position of a second image.

A lateral positioning device (100) for a sheet element (20, 20′) in a sheet element processing machine; a detector lever (130) articulated relative to a horizontal axis, which performs a descending movement from a high position to a low position; a first end (132) of the detector lever (130) contacts, in a low position of the lever, with an upper face of the sheet element. A second end (133) of the detector lever (130) is fitted with a target (135) that cooperates with a position detector (140) to generate a signal dependent on the thickness of the sheet element (20, 20′) and the number of sheet elements (20, 20′) present at the level of the first end (132) of the detector lever (130).
