An apparatus for controlling curl in sheets between two transports includes a curved baffle placed between the two transports. A thin layer of high velocity air is applied to the curved baffle. The high velocity air layer, which will have a tendency to follow the curved baffle (Coanda effect), will divert sheets (Bernoulli effect) towards the curved baffle. By positioning the curved baffle between the two transports and by applying a uniform air stream to it, a lower pressure area will be created. This will flatten the trajectory of the sheets and ensure acquisition by the downstream transport.

A feeding unit to feed a component in an automatic manufacturing machine, which has at least one holding head designed to receive and hold the component; a conveyor to cyclically move the holding head along an application path; and a rotation station arranged along the feeding path and in which the holding head rotates relative to the equipment and around a rotation axis to vary the orientation of the component. The conveyor has a closed curve guide arranged in a fixed position along the application path; and an equipment supporting the holding head and provided with at least one slide coupled to the guide so as to freely slide along the guide. An actuation system controls rotation of the holding head around the first rotation axis and has a cam and a cam follower roller, which can be coupled to the cam and mechanically connected to the holding head.

A unit for applying first and second tabs, obtained from first and second webs, to a chassis web includes an applicator drum rotatable about an axis and including a main body. A plurality of carriers is movable between a lowered position close to the axis and a raised position away from the axis, each including a suction portion. A first carrier first suction and non-suction portions aligned along the axis. A second carrier includes second suction and non-suction portions aligned along the axis. The first suction portions alternate with the second non-suction portions and the first non-suction portions alternate with the second suction portions. A first system holds the first web on the applicator drum upstream of a cutting device. A second system holds the second web on the drum upstream of the cutting device.

Systems and methods utilizing stationary and/or moveable cutting components provide limited interference with web processing operations, such as pad spin and pitch alteration. Heat, laser, fluid, or mechanical cutting operations may be used, including respectively, a heated element (e.g., wire, ribbon, bar, or embossing or perforating element) that may be triggered inductively, water or steam jets, or improved knife/anvil cooperation.

Disclosed is an image forming apparatus, including: a first guide guiding one surface of a sheet downstream of a fixing unit fixing a toner image on the sheet and upstream of discharging rollers discharging the sheet to a stacking portion in a sheet conveying direction; a second guide facing the first guide, the second guide guiding the other surface of the sheet; protrusions with openings provided on the second guide in a sheet width direction orthogonal to the sheet conveying direction; recesses provided on the first guide in the sheet width direction, the recesses facing the protrusions; and a blower unit blowing air toward the sheet via the openings provided on the second guide, wherein a corrugated shape is formed in the width direction on the sheet to which air is blown by the protrusions provided on the second guide and the recesses provided on the first guide.

A suction mechanism for suctioning a loop transporting belt a medium processed by a processing unit, a rotation mechanism for rotating the transporting belt, a stacker for stacking the medium transported by the transporting belt, and a change mechanism for changing a movable area are included. The rotation mechanism, after suctioning the medium to the transporting belt to rotate in a first rotation direction to transport the medium in a first transport direction, rotates the transporting belt in a second rotation direction to transport the medium in a second transport direction to stack the medium on a stacker. The change mechanism narrows a movable area when the medium is transported in the second transport direction compared to an area when the medium is transported in the first transport direction.

An apparatus is disclosed. For example, the apparatus includes a paper feed to feed print media a single sheet at a time, a plurality of rotating discs, wherein each one of the plurality of rotating discs comprises an elastomer ring to secure a leading edge of the single sheet against a registration wall and initiate a flipping process, a curved baffle positioned above the plurality of rotating discs and the single sheet, an air duct located above the plurality of rotating discs and the single sheet to force an air flow towards the curved baffle, wherein the air flow follows a shape of the curved baffle to create a low pressure zone above the single sheet to keep a trailing edge of the single sheet levitated during completion of the flipping process, and a movable platform to hold a stack of the print media.

The present invention is a paper sheet transport system including: an air blowing device that generates an air flow for transporting paper sheets; a transport device that transports paper sheets with the air flow; and a control device that controls the air blowing device, and the control device includes a measuring unit that measures the speed of paper sheets on the transport device, and an adjusting unit that adjusts the air flow according to a result of the measurement. The control device includes a detecting unit that detects arrival of paper sheets at a deceleration region, and, when paper sheets in the deceleration region are faster than a specific speed, the adjusting unit causes the air blowing device to generate an air flow in an opposite direction to that of an air flow for transporting the paper sheets.

The present invention relates to an inversion transfer module (60) for a converting machine having a printing module (16) comprising a first printing unit (17) arranged to print on a top side (S1) of the sheet (1), and a second printing unit (17) arranged to print a bottom side (S2) of the sheet. The inversion transfer module is arranged between the first printing unit and the second printing unit and comprises a first inversion vacuum transfer (62) arranged to contact the first side of the sheet and a second inversion vacuum transfer (64) configured to contact the second side of the sheet, whereby the inversion transfer module is configured to change the side of adherence and transportation of the sheet.

A sheet stacking device includes a stacker, a detector, a blower, and a moving device. A sheet is stacked on the stacker. The detector detects a stacking amount of the sheet on the stacker. The blower blows air to the sheet stacked on the stacker. The moving device moves the blower with respect to the stacker based on the stacking amount of the sheet detected by the detector.
