A bridle device and a method for producing a steel strip in which snaking of a steel strip that occurs during production of a high-silicon steel strip is suppressed. The bridle device includes a pair of upper and lower rotatable endless belts or a pair of upper and lower rotatable caterpillars configured to pinch a steel strip. The bridle device is movable or swingable in a steel strip width direction by using a steering mechanism. The bridle device further includes a rolling reduction mechanism configured to perform rolling reduction on a pinched portion of the steel strip by using the pair of upper and lower endless belts or the pair of upper and lower caterpillars. The steering mechanism moves or swings the bridle device in the steel strip width direction, and the rolling reduction mechanism performs rolling reduction on one of end portions in the steel strip width direction.

An apparatus and method for correcting meandering of an electrode are provided. An edge position of the electrode is feedback-controlled so that a determination edge position sensor (EPS) edge position value matches a determination EPS edge reference value, and each of a line edge position control (EPC) unit and an input clamp unit is feedback-controlled so that a direction in which the electrode is transferred from a line EPC roller is corrected and an input inclination of an input clamp roller is corrected by comparing pieces of data on the determination EPS edge position values when the determination EPS edge position values change over time to converge to the determination EPS edge reference value by the feedback control, and the determination EPS edge reference value.

A conveying apparatus includes: a conveying unit configured to convey a sheet in a conveyance direction along a conveyance path; a sheet holder arranged upstream in the conveyance direction from the conveying unit to rotate around an axis, the axis extending in a first direction intersecting with the conveyance direction; a tensioner arranged between the sheet holder and the conveying unit in the conveyance path and configured to apply tension to the sheet with the sheet being curved; and a first side guide attached to the tensioner and having a first guide surface, the first guide surface spreading along the conveyance direction and a second direction intersecting with the first direction. The tensioner includes an oblique roller configured to guide the sheet to the first guide surface.

A system for forming glass rolls is provided. The system includes a glass ribbon supply system configured to supply a glass ribbon, a cutting system configured to cut the glass ribbon to a first portion and a second portion, a first glass winding system configured to wind the first portion of the glass ribbon to form a first glass roll, and a second glass winding system configured to wind the second portion of the glass ribbon to form a second glass roll.

A printer device includes: a pair of rack gears arranged in a staircase-like shape on a paper conveyance direction side of a continuous paper accommodated in a recessed accommodation part that accommodates a roll-shaped continuous paper and having tooth rows arranged in a first direction orthogonal to the paper conveyance direction so as to face each other; a pinion gear fitted into the tooth rows; and a pair of paper guides that are respectively provided at a position of an upper rack gear that is closer to a center side in the first direction from one end portion in the first direction and a position of a lower rack gear that is closer to the center side in the first direction from another end portion in the first direction or the other end portion. The paper guide provided on the upper rack gear is mounted to an upper mounting part extending from a back surface of the upper rack gear opposite to the tooth row to the paper conveyance direction side.

Provided is a device for correcting meandering of a strip material capable of correcting meandering caused in the strip material and conducting stable conveyance even when the meandering amount is small. The device for correcting meandering in a non-contact conveyance of a strip material that supports and conveys the continuously travelling strip material at a non-contact state by floating the strip material using a group of one or more floaters arranged in series, is characterized in that a gas nozzle for jetting a gas to a lower surface of the strip material is disposed in at least one section between the most upstream floater among the floater group and a conveyance roll located immediately upstream of the floater, between adjacent two floaters and between the most downstream floater among the floater group and a conveyance roll located immediately downstream of the floater as a mechanism for imparting tilting to the strip material to operate the tilting of the strip material in the widthwise direction above the floater.

A deviation correction apparatus includes a width detecting apparatus configured to detect a width of a coating layer of an electrode plate, a processor communicatively connected with the width detecting apparatus and configured to determine a centerline position of the electrode plate based on the width of the coating layer, and a deviation correction mechanism configured to perform deviation correction for the electrode plate based on the centerline position of the electrode plate and a preset standard centerline position.
