A unit for thermosetting printed fabrics, comprising: a heated roller rotating about a rotation axis and having a cylindrical outer surface, at least one fabric guiding element having an inner wall facing the cylindrical outer surface of the heated roller and defining a gap with the cylindrical outer surface of the heated roller, for passing the fabric wherein said fabric guiding element is carried by an adjusting device rotatable about said rotation axis to adjust the angular position of said guiding element about said rotation axis.

A unit for thermosetting printed fabrics, comprising: a heated roller rotatable about a rotation axis and having a cylindrical outer surface, at least one fabric guiding element having an inner wall facing the cylindrical outer surface of the heated roller and defining a gap with the cylindrical outer surface of the heated roller for passing the fabric, wherein said at least one fabric guiding element has a fume suction chamber connected to a suction device, and wherein said inner wall has a plurality of holes communicating with said suction chamber.

A web handling system is disclosed. The web handling system includes a roller wheel including two or more rollers configured to engage a print medium, a motor to rotate the roller wheel and a controller to transmit a signal to the motor indicating which of the two or more rollers are to engage the print medium.

When a length in a conveying direction of a margin to be cut off is shorter than a predetermined distance between a cutting part and a second conveying part, a sheet cutting machine feeds a first sheet to the cutting part using a first conveying part while keeping the second conveying part positioned at a conveying path. When the length is equal to or longer than the predetermined distance, the machine feeds the first sheet to the cutting part using the first conveying part after upwardly retracting the second conveying part from the conveying path using a retracting mechanism.

An aspect of the present invention includes: a sheet storage unit configured to store sheets; an air blowing unit configured to blow air; a duct configured as a flow passage to an air blowing outlet for blowing air sent from the air blowing unit toward the front end of an upper part of a sheet bundle stored in the sheet storage unit; a suction transport unit configured to suck a sheet floating from the sheet bundle upward and transport the sheet; a shutter member configured to block the flow passage in the duct; and an openable/closeable member configured to open an opening part of the duct, such that air staying in the duct by blocking the flow passage by the shutter member is discharged from the opening part.

A sheet conveying device includes a conveyor for conveying a sheet along a predetermined conveyance path and a feeder unit for supporting the sheet to be fed to the conveyor. The conveyor includes a first guide part for guiding the sheet toward a downstream side in the conveying direction in a direction inclined at a downward gradient, a second guide part for guiding the sheet from the first guide part toward a further downstream side in a direction inclined at an upward gradient, a suction roller arranged at the first guide part for conveying the sheet supported by the feeder unit toward the downstream side, and a first conveyance roller arranged at the second guide part and for conveying the sheet conveyed by the suction roller toward the downstream side one at a time.

An aspect of the present invention includes: a sheet storage unit configured to store sheets; an air blowing unit configured to blow air; a duct configured as a flow passage to an air blowing outlet for blowing air sent from the air blowing unit toward the front end of an upper part of a sheet bundle stored in the sheet storage unit; a suction transport unit configured to suck a sheet floating from the sheet bundle upward and transport the sheet; a shutter member configured to block the flow passage in the duct; and an openable/closeable member configured to open an opening part of the duct, such that air staying in the duct by blocking the flow passage by the shutter member is discharged from the opening part.

A document feeder for a printer may include an upper part and/or a lower part. The upper part may include a feeding roller arrangement configured to engage with an upper face of a document. The lower part may include a retaining surface. The lower part may further include a sliding element which, in at least an operation mode of the document feeder, may have a portion that projects with respect to the retaining surface for supporting a lower face of the document in such a way that at least a portion of the document is raised with respect to the retaining surface.
