A sheet feeding device includes a sensor, a roller, a support, circuitry, and a spool. The sensor detects a step at a leading end of a sheet roll. The roller and the sensor are disposed at different positions in a circumferential direction of the sheet roll. The support supports the sensor and the roller to bring the sensor and the roller into contact with the sheet roll. The circuitry acquires a sensor signal. The spool is insertable through a sheet tube of the sheet roll to rotate the sheet roll. The sensor and the roller face an axial center of the spool. The support is pivotable within a range in which the sensor does not contact the spool. The circuitry detects first and second inclinations of the sensor signal when the leading end passes by the roller and the sensor, respectively, to determine whether the leading end is present.

A conveyance unit conveys the sheet to an accumulation portion. A half-folding processing unit includes a folding roller pair and performs a half-folding process on the sheet bundle. A conveyance roller pair conveys the sheet bundle. A square back processing unit performs a square back process on the sheet bundle and includes a pair of clamp portions. A length of a conveyance path from the folding roller pair to the pair of clamp portions is larger than a half of a length of a long side of a sheet of a maximum size. In a state in which conveyance by the conveyance roller pair of a first sheet bundle to be subjected to the square back process is stopped, the conveyance unit conveys at least one sheet included in a second sheet bundle subsequent to the first sheet bundle toward the accumulation portion.

A spool unloading device comprising: a spindle; a first bulk spool of material is mounted on the spindle, wherein the spindle is rotatably controlled to dispense the material; a series of pulleys for receiving the unspooled material such that a variable length of the material is stored within the device before exiting the device to an upstream equipment; and a drive mechanism for indexing the unspooled material exiting the spool unloading machine at a controlled rate.

A position roller for meander control includes, in one example, a roller with a rotational axis; a first ball joint supporting a distal end among both ends of the rotational axis for pivotal movement; an XZ driver that drives a proximal end among both ends of the rotational axis into two-dimensional motion in a plane; and a base supporting the first ball joint and the XZ driver.

The present invention relates to an automatic image positioning system for a sheet material. The automatic positioning system is used to convey the sheet material from a feeding place to a paper gripper bar. The automatic positioning system includes a first conveying device and a second conveying device, the automatic positioning system further includes a photoelectric detection device used to perform positioning and positioning correction on the sheet material, and the photoelectric detection device is provided at a starting end of the second conveying device (3). Compared with the prior art, the present invention utilizes an photoelectric detection device to perform positioning and positioning correction on a material, uses a vacuum adsorption component to stabilize the material, and has advantages of high systemic positioning accuracy, high positioning correction accuracy, and strong material adaptability.

A system comprising: a source of a tape comprising a material associated with an adhesive and at least one removable liner; an applicator head; a cutting mechanism; at least one drive feeding mechanism configured to index the tape from the source to the applicator head at a controlled rate; wherein the applicator head is controllable to apply the material on a surface or a substrate; and wherein the applicator head comprises a cutting mechanism configured to sever the material while leaving the at least one removable liner intact.

A sheet conveyance apparatus includes a driving roller, a steering portion configured to change an inclination angle of a rotational axis of the driving roller, a follower roller configured to nip and convey a sheet together with the driving roller and pivot about a pivot axis, a contact/separation mechanism, a first detection portion configured to detect vibration of the follower roller, a second detection portion configured to detect positional deviation of the sheet, and a control portion configured to execute a correction operation of correcting the positional deviation of the sheet and to execute a predetermined process for causing the correction operation to be started after the driving roller and the follower roller have been switched from the separation state to the contact state and after the vibration of the follower roller has settled down within a predetermined range.

A sheet conveyance device includes a sheet conveyance passage, a mounting plate, and a sheet detection sensor. The mounting plate is fixed to a recessed portion formed in the inner wall surface of the sheet conveyance passage at its one side it. The sheet detection sensor is fitted on the mounting plate. The sheet detection sensor has a sensor surface. The mounting plate has a mounting surface on which the sheet detection sensor is mounted and a first projection piece which projects from the mounting surface toward the sheet conveyance passage and which is grounded. The first projection piece is disposed upstream, in the sheet conveyance direction, of the sheet detection sensor on the mounting plate. The distance from the mounting surface to the distal end of the first projection piece is greater than the distance from the mounting surface to the sensor surface.

One aspect of the present disclosure relates to an auto-splicing device for an electrode and an auto-splicing method, and more particularly, to an auto-splicing device for an electrode and an auto-splicing method, which can minimize connection defects between the running electrode and the new electrode, wherein the running electrode and the new electrode connected and supplied to the running electrode are aligned on the basis of their coating lines by using the auto-slicing device.

A medium feeding apparatus includes a feed roller to feed a medium, a driving source to generate a driving force for driving the feed roller, a driving force transmission assembly to transmit the driving force to the feed roller, an applying part to apply a load against rotation of the feed roller, and control circuitry to control the driving source. The control circuitry controls the driving source to stop the feed roller and keeps the driving force transmission assembly static.
