A separation member separates a sheet, conveyed by a separation roller in a conveying direction, from remaining sheets supported by a support member. At least one of a first guide and a second guide is a movable guide which moves in a width direction orthogonal to the conveying direction to increase and decrease a distance therebetween. An urging member is retained, at one end thereof, by a base portion in an elastically deformed state and urges the separation member toward the separation roller. In response to the movable guide decreasing the distance between the first guide and the second guide, an engaging mechanism reduces elastic deformation of the urging member by moving the base portion in a first direction. In response to the movable guide increasing the distance, the engaging mechanism moves the base portion in a second direction opposite to the first direction.

To prevent a support shaft from breaking during production and assembly. A transfer tool of the present invention is a transfer tool that allows a transfer tape fed out from a feed reel to be wound onto a take-up reel via a transfer head, and includes a rotation transmission means having a feed gear, a take-up gear, and an intermediate gear, that have a disc shape, and transmitting rotation of the feed reel to the take-up reel. The intermediate gear is rotatably supported by an intermediate support shaft, and the intermediate gear is provided with a stress relief means that relieves bending stress when the intermediate gear is attached to the intermediate support shaft.

A sheet folding apparatus includes a sheet folder and circuitry. The sheet folder includes a sheet folding part, and an additional folding part to reinforce a folding portion in the sheet. The circuitry is to control the sheet folder to form and reinforce the folding portion in the sheet; acquire, before completion of a folding operation, first sheet information of the sheet and first folding information indicating a type of the folding operation on the sheet; run a trained model obtained through machine learning executed using second sheet information of a training sheet, second folding information indicating a type of the folding operation on the training sheet, and multiple training datasets including a folding evaluation value; estimate the folding evaluation value after the completion of the folding operation on the sheet; and determine the type of a control content in the folding operation, based on the folding evaluation value.

The present disclosure relates to a transition method and system from helical winding to hoop winding of composite fibers. The method includes: setting a slip coefficient, and performing iterative calculation forward from an iteration starting point according to an equation set of a winding angle and a center angle of rotation to obtain a winding angle at an iteration termination point; and if the winding angle at the iteration termination point is greater than a first preset angle, adjusting the slip coefficient corresponding to a cylinder body according to the first preset angle, extending a length of a helical winding transition section to a front equator, and starting the hoop winding at the front equator at the first preset angle to complete planning of the helical winding transition section.

A conveyance apparatus includes a conveyance unit, a first cursor, a second cursor, and a controller. The conveyance unit conveys a sheet in a first direction. The first cursor regulates movement of the sheet in a second direction intersecting the first direction. The second cursor presses the sheet against the first cursor. The controller controls a speed at which the second cursor positioned away from the sheet moves toward the sheet.

Provided is a sheet feeding apparatus provided with a storage chamber for storing sheets, a sheet feeding unit including a delivery roller for contacting the sheet stored in the storage chamber to deliver the sheet from the storage chamber, a support member for supporting the storage chamber to allow the chamber to be installed and pulled out in/from an apparatus main body, and a press force switch mechanism including an operation member to switch a press force used for the delivery roller to contact the sheet, the sheet feeding unit is configured to be capable of being installed and pulled out in/from the main body apparatus integrally with the storage chamber, and the press force switch mechanism is provided in the sheet feeding unit.

A feed roller mechanism that feeds a continuous paper while nipping the continuous paper between a first roller and a second roller that face each other, the feed roller mechanism includes a plate-shaped first support member that supports the first roller, and a plate-shaped second support member that supports the first support member, wherein the first roller nips the continuous paper with the second roller by a deflection reaction force of the first support member.

A sheet feeding device includes a pick-up roller, a sensor, and a sheet feeding controller. The pick-up roller draws out a plurality of sheets one by one from a sheet table on which the plurality of sheets are loaded. The sensor detects presence or absence of the sheet. The sheet feeding controller controls drive to raise the pick-up roller on the basis of a detection result of the sensor.
