The disclosure relates to a method and apparatus for uncut material detection while lifting from an automated cutting table select pieces of thin, flexible material. The apparatus comprises a structured energy source and a structured energy sensor. The structured energy can be used to detect undesired lifting of a peripheral portion of the flexible material resulting from the presence of uncut material.

A device and a method allow for adhering sealing tape to open end of a multilayer sheet, usable at the production line and at the installation site. The device comprise means for applying pressure and heat onto the sealing tape and cutting blades for removing protruding edges of the sealing tape after it was adhered. The method comprise providing of a sealing tape, attaching and adhering the sealing tape to an open end of a multi-wall sheet by means of heat and/or pressure and adhesive and removal of protruding edges using cutting blades.

A sheet feeder includes a controller configured to perform a driving process of supplying a motor with an electric current to rotate a roller, perform a stopping process of stopping supplying the electric current in response to determining that the motor has not rotated before a second sensor detects a sheet, when an accumulated rotational quantity of the roller is less than a threshold, set a retry upper limit to a first value, the accumulated rotational quantity being detected by a first sensor in the driving process performed for a first time, when the accumulated rotational quantity of the roller is equal to or more than the threshold, set the retry upper limit to a second value more than the first value, and repeatedly perform the driving process and the stopping process until a number of retries reaches the retry upper limit or until the second sensor detects the sheet.

A header cover encloses an end of an unwoven material cylinder to protect the unwoven material from damage or debris during storage or transportation. Unwoven material cylinders are commonly used to produce products such as clean suits, baby diapers, absorbent material, etc. The header cover includes a cover disc, a plurality of lateral-interfacing flaps, and a tethering ring. The cover disc and the plurality of lateral interfacing flaps encapsulate an end of the unwoven material cylinder. The plurality of lateral-interfacing flaps is perimetrically and foldably connected to the cover disc to allow the header cover to fold over an edge of the unwoven material cylinder. The tethering ring is adjacently connected to each lateral-interfacing flap of the plurality of lateral-interfacing flaps, such that as one lateral-interfacing flap is folded, every lateral interfacing flap is folded in the same direction.

Provided is a document conveyance apparatus that conveys a document along a document conveyance path including a reading position at which an image on a surface of the document is read, the document conveyance apparatus including: a hardware processor; an end detector that detects an angle of a corner portion of a front edge of the document; and an inclination detector that detects an amount of inclination of the front edge, wherein, in a case where it has been determined that the corner portion of the front edge includes a right angle portion on the basis of information obtained from the end detector, the hardware processor determines the amount of inclination of the front edge obtained from the inclination detector as an amount of inclination of the document, and performs inclination correction of the image read at the reading position.

The disclosure relates to a method and apparatus that separates and efficiently captures from an automated cutting table select pieces of thin, flexible material in an orderly manner which prevents damage to the selected piece while preventing the undesired lifting or movement of the surrounding material. The apparatus comprises a pick head assembly including a cylinder with a plurality of orifices that communicates with the selected piece to maintain contact between the selected piece and the cylindrical surface while the selected piece is being removed.

Disclosed herein is a sheet processing apparatus comprising a sheet tray configured to hold a bundle composed of the sheets fed from conveyance rollers, a wait path configured to keep waiting following sheets upstream the conveyance rollers, an accumulating tray configured to hold a sheet bundle, delivery rollers configured to nip the sheet bundle mounted on the sheet tray and the following sheets, to set off from one another, and to deliver them to the accumulating tray, and to switch back the following sheets to the sheet tray, and a conveyance member configured to convey the following sheets from the sheet tray.
