Folding information and printing surface information, included in content information of a sealed letter creation job, are compared with content printing conditions stored in a storage section, and an appropriate condition (a conveyance path after printing, execution/non-execution of image rotation, and printing page order) is selected such that the position of a window of a windowed envelope is aligned with the position of specifying information printed on a print sheet P to be a content when the print sheet P is enclosed in the envelope. A convey section and a printing section are controlled based on the selected content printing condition.

A folding machine comprises a blade folding unit having a first and a second folding roller, the folding roller axes thereof defining a folding roller plane, and having a folding blade which is oriented and is movable in a folding blade plane which is oriented perpendicularly to the folding roller plane and intersects the folding roller plane in an intersection line. The folding blade is arranged in a retracted position in or below a horizontal plane which comprises the intersection line.

An apparatus for forming and sorting informational items comprises a folding unit, a conveyor belt, a camera, a controller, and a diverter assembly. The folding unit forms a folded article from a sheet of paper. The conveyor belt transports the folded article. The camera captures an image of the folded article as it passes by the camera. The controller receives and processes the image, and the diverter assembly causes the folded article to move off of the conveyor belt when the controller determines that the folded article fails to satisfy at least one predetermined criteria.

An enclosing device to insert an enclosure into an envelope conveyed to an enclosing position includes an envelope conveyor and an enclosing unit. The envelope conveyor conveys the envelope to the enclosing position. The enclosing unit opens a frontage of the envelope such that the enclosure is inserted into the envelope that has reached the enclosing position and includes an opening amount adjuster to adjust an opening amount of the frontage when the enclosure is inserted into the envelope. The opening amount adjuster adjusts the opening amount, depending on a flap length and a body length. The flap length is a length of a flap of the envelope in a conveyance direction in which the envelope is conveyed to the enclosing position. The body length is a length of a body of the envelope in the conveyance direction.

A buckle folding unit for sheets includes a buckle plate, three rollers that form a transport roller pair and a folding roller pair, and a blown-air nozzle for guiding the sheets. The at least one blown-air nozzle emits a blown-air jet in a direction radial to a common roller of the transport roller pair and the folding roller pair. The air jet places the sheet against the surface of the common roller and guides it into a nip of the folding roller pair in a defined way, advantageously resulting in an improved quality of the fold. A sheet-fed folding machine including a buckle folding unit is also provided.

A machine for folding sheets receives a stream of sheets. A first folding unit is followed by a further unit. The first folding unit has at least one buckle plate and at least two folding rollers to fold the sheets. A monitoring device checks the stream for defects. A control unit activates a removal device for removing waste products when a defect is detected. The monitoring device is disposed at the entry region of the buckle plate and monitors the stream in the buckle plate. The removal device is disposed downstream of the first folding unit and upstream of the further unit. The system, which is suitable for industrial folding machines, reliably detects unusable waste products in the folding process even before production might be affected.

A folding unit has two folding rollers with a common folding nip. A first insertion slot has a first insertion plane for a selectively insertable buckle plate and is configured so that a buckle plate mouth of the buckle plate is at an inlet side of the folding nip. A second insertion slot has a second insertion plane for a buckle plate. The second insertion plane is inclined with respect to the first insertion plane and the second insertion slot is designed for the buckle plate mouth of the selectively inserted buckle plate to be arranged on the inlet side of the folding nip. Printing substrates with different properties are processed in a high-quality and highly productive manner in a pocket folding process, especially in buckle folding units of industrial folding machines.

The present invention relates to a system (100) for adjusting positions of rollers in an outsert making machinery. There are frequent manual errors in existing outsert-making machinery during adjustment of grooving rollers. The system (100) includes an input interface (30) which receives input data regarding geometrical parameters of a strip (13) and final outsert (16) which sends data to a processor (50) configured in a workstation (40). The processor calculates an output data in the form of geometrical details of the grooving rollers (21) and positions of the grooving rollers (21) on grooving shaft(s) (22) and displays the output data on a display (60). Based on data displayed, an operator can manually adjust the positions of the grooving rollers (21) or the workstation (40) actuates a mechanism (70) to adjust grooving rollers (21) and a control unit (80) to adjust operational parameters of folding units (14a, 14b).
