A sheet conveying device includes a conveyor, a curved conveyance passage, a conveyance sensor, and processing circuitry. The conveyor conveys a sheet. The sheet is conveyed by the conveyor along the curved conveyance passage. The conveyance sensor detects a presence of the sheet and is disposed at a curved position of the conveyance passage. The processing circuitry determines clogging of the sheet from an output result of the conveyance sensor. When a specific type of the sheet is conveyed, the processing circuitry stops determination of clogging of the sheet for a period of time from when the conveyance sensor detects passage of a leading end of the sheet to when a trailing end of the sheet passes the conveyance sensor.

A processing machine includes at least one further processing unit following at least one processing unit configured as an application unit in a transport direction of a substrate. At least one transport unit is arranged between the at least one processing unit configured as an application unit and the at least one succeeding processing unit. The at least one transport unit includes a plurality of transport elements arranged one behind the other in the transport direction. The plurality of transport elements are individually axially adjustable, or the plurality of transport elements are groupwise axially adjustable.

A processing machine includes at least one processing unit configured as at least one shaping unit following, in a transport direction of a substrate, at least one processing unit configured as at least one application unit. Additionally, at least one transport unit is arranged between the at least one application unit and at least one succeeding processing unit. The at least one transport unit includes a plurality of transport elements that are arranged one behind the other in the transport direction. At least one transport element is axially adjustable based on detection of at least one image-producing element of a substrate by at least one sensor for substrate alignment.

A medium-feeding apparatus includes a movement detector configured to output information on movement of a medium in a first direction parallel to a feeding direction and in a second direction intersecting the feeding direction. A control unit is configured to perform abnormal feeding processing depending on the movement of the medium in the second direction. In the abnormal feeding processing, the control unit stops feeding of the medium when a first value indicating the movement of the medium in the first direction is within an allowable range and when a second value indicating the movement of the medium in the second direction exceeds a threshold, and continues feeding of the medium when the first value is outside the allowable range.

A defect detecting device includes a detection unit and a movement mechanism. The detection unit includes a support, an arm supported by the support swingably around a swing shaft, and a sensor for detecting a displacement of the arm relative to the support. The arm includes contactors. The movement mechanism keeps the contactors away from a feed plane during a feed phase of a sheet panel, and moves the contactors to the feed plane and then moves the contactors from the feed plane during a pause phase of the sheet panel. The defect detecting device further includes a determination part configured to determine whether a defect in bag making is present based on data from the sensor.

A roll medium transport apparatus includes a feed roll medium support unit that feeds a roll medium, a takeup roll medium support unit that winds up the roll medium that has been fed, a position acquiring unit that acquires a position of a side end portion of the roll medium that is to be fed, a radiating unit capable of radiating light with a position of the side end portion being used as a reference point. The radiating unit is held by the feed roll medium support unit and allows the light to be radiated to a takeup roll that winds up the roll medium.

It is an object of the present invention to provide a sheet supplying apparatus in which the user can select either automatic sheet feeding or manual sheet feeding. A sheet supplying apparatus of the present invention includes a driving unit configured to cause a roll including a wound consecutive sheet to rotate in a first direction for feeding the sheet or a second direction opposite to the first direction, a first sensor that detects a leading end portion of the sheet separated from an outer circumferential surface of the roll, a second sensor that detects the leading end portion which is manually set in a conveyance path by a user, and a determination unit configured to determine whether or not automatic sheet feeding is performed on the basis of a detection result of the second sensor.

It is an object of the present invention to specify a type of sheet to be used using a sensor that detects a sheet separated from a roll at the time of automatic sheet feeding. A sheet supplying apparatus according to the present invention includes a driving unit configured to cause a roll including a wound consecutive sheet to rotate in a first direction for feeding the sheet or a second direction opposite to the first direction, a sensor that detects the sheet separated from an outer circumferential surface of the roll, wherein, in a case in which the sensor detects a leading end portion of the sheet while the roll is being rotated in the second direction, the driving unit changes a rotation direction of the roll from the second direction to the first direction and feeds the sheet, and wherein the sheet supplying apparatus further includes a specifying unit configured to specify a type of the sheet on the basis of an output of the sensor while the roll is being rotated in the second direction.

A system and method of controlling the input and output speed of a continuous sheet of stock material is provided. More specifically, the present invention relates to a system and method used to perform an operation on a continuous sheet of stock material in a high speed manufacturing system. The continuous sheet of stock material may subsequently be received by a second system that performs a different operation on the stock material. In one embodiment, the second system forms the stock material into tabs for container end closures. The system includes an infeed accumulation device and an outfeed accumulation device. The infeed and outfeed accumulation devices enable the system to operate at a variable rate and out of phase with a high speed, coil fed manufacturing system to which the system may be removably integrated.

A printing apparatus includes a transport unit which includes a transport roller pair which transports a medium in a transport direction, a printing unit which prints onto the medium, a winding unit which winds the printed medium, and a tension application unit which applies a tension to the medium at a position between the transport roller pair and the winding unit. The tension application unit includes a pair of arms which are capable of rotating. A tension bar is supported on one end of the arms and comes into contact with the medium. The bar is rotated from an upper limit position to a lower limit position by transportation of the transport unit being performed two or more times.
