A system for controlling curl in sheets passing beneath a camera includes applying a thin layer of high velocity air to a curved baffle positioned beneath the camera. 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 along the media paper path 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 thereby remove curl before the sheets pass the camera.

An apparatus for controlling cross curl in corners of sheets between in-line transports includes a curved baffle placed between the two transports. A thin layer of high velocity air is applied to the curved baffle only at lead edge corner regions of the sheets. The high velocity air layer, which will have a tendency to follow the curved baffle (Coanda effect), will divert corners of the sheets (Bernoulli effect) towards the curved baffle. By positioning a 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 corners of the sheets and ensure passage between downstream baffles and acquisition by a downstream transport.

Printing apparatuses include (among other components) a photoreceptor (that is adapted to contact and transfer marking material to a printing side of sheets of media), a transport belt adjacent the photoreceptor, a baffle, and an air outlet. The sheets of media are moved by the photoreceptor across a gap to the transport belt in a “processing direction.” The baffle is adjacent the back side of the sheets of media (the side that is opposite to the printing side of the sheets of media). The air outlet is also positioned adjacent the back side of the sheets of media, and the air outlet is adapted to direct a stream of air along the baffle and between the baffle and the back side of the sheets of media to lift the sheets of media off the photoreceptor without damaging the sheets of media or disturbing the unfused marking material thereon.

The invention relates to a device and a method for stacking card-like data carriers. The device comprises (i) a conveying device for transporting individual card-like data carriers downstream along a conveying path and (ii) a stacking unit for selectively transferring and stacking card-like data carriers conveyed along the conveying path. The conveying device is arranged to convey the card-like data carriers in such a way that they are fixed to it in a hanging mode of transport. The stacking unit is arranged to selectively release certain ones of the card-like data carriers conveyed along the conveying device from the latter in order to transfer them directly—i. e. in particular without intermediate processing, intermediate transport or intermediate storage—into a card magazine and to stack them therein when the card magazine is arranged in a stacking area at a stacking position which, in relation to the direction of gravity, is situated below the conveying path.

The invention relates to a device, in particular a roll cross-cutter, for forming a shingle stream of underlapping or overlapping sheets, in particular of paper or carton sheets, having a transport apparatus for transporting sheets, having a shingling apparatus for underlapping or overlapping sheets in regions, having a deceleration apparatus, downstream of the shingling apparatus in the transport direction of the sheets, for decelerating shingled sheets, in particular by forming a deceleration gap for the passage of shingled, combined sheets, and, preferably, having a cross-cutting apparatus upstream of the shingling apparatus for cutting a material web into individual sheets. According to the invention, the shingling apparatus is designed to be adjustable, in dependence of the cut length, in and/or opposite the transport direction of the sheets.

According to some embodiments a conveying device for conveying goods includes at least one conveyor belt with an outer contact face against which the goods to be conveyed are held during conveyance. A main negative pressure holding area is provided adjacent to the conveyor belt, the main negative pressure holding area being configured to hold or release the goods to or from the conveyor belt by negative pressure. The conveyor belt includes at least one suction chamber on the outer contact face forming an additional negative pressure holding area, the suction chamber being in fluid communication with negative pressure holding means through at least one opening transversely going through the conveyor belt.

A feeding unit to feed components in an automatic manufacturing machine; the feeding unit has: a plurality of sucking holding heads, which are each designed to receive and hold a corresponding component; a closed curved guide, which is arranged in a fixed position along the application path; a plurality of equipment, each supporting a corresponding holding head and provided with at least one slide, which is coupled to the guide so as to freely slide along the guide by means of a plurality of wheels; a suction chamber, which is mounted so as to rotate around a rotation axis; and a flexible connection system, which pneumatically connects the suction chamber to each holding head.

A carousel for transporting articles includes: a body rotated by a motor around a main axis, a stationary cam around the main axis and a plurality of transfer units mounted on the body to rotate around the main axis. Each unit includes a transfer element having a radially external portion to retain or release an article. The element is pivoted on the body around an auxiliary axis radial to the main axis and is coupled to the body to move along the auxiliary axis. The element is coupled to the stationary cam to rotate around the auxiliary axis. A pair of auxiliary cams is coupled to the element and integral with the body and auxiliary cam-followers are interposed between the element and the auxiliary cam to move on the auxiliary cams during rotation of the element around the auxiliary axis and move the element along the auxiliary axis.

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.

A transfer mechanism includes a main rotating member, a first driving unit, a support mechanism, a holding unit, a second driving unit and control unit and transfers a sheet member from a pickup position to a delivery position. The support mechanism is connected to the main rotating member and the holding unit. The control unit controls the second driving unit in such a manner that, when the sheet member is placed in at least one of the pickup position and the delivery position, a position of the holding unit is not substantially changed in a state where the main rotating member rotates around the rotational axis in the first rotation direction.
