An apparatus for printing on one or both sides of flat objects. The apparatus includes a loop-shaped conveying path for the flat objects; a feed conveyor configured to feed the objects to be printed into a first section of the conveying path; a printer configured to print the objects one at a time; a first discharge conveyor configured to discharge the objects to be printed one at a time downstream of the printer from the first section towards a second section; a first collector configured to collect the objects downstream of the first discharge conveyor at the second section discharged from the first discharge conveyor in a stack; a stack conveyor configured to convey a (partial) stack of the objects along the second section; and a second collector configured to receive at least one (partial) stack and feed the objects upstream to the printer into the first section.

A first sheet conveying path extends from a sheet supply portion toward a sheet discharge portion. A second sheet conveying path extends, from a diverging position in the first sheet conveying path, toward a switch-to-back portion. A third sheet conveying path is a conveying path for the sheet that is reversed by the switch-to-back portion. A first movable guiding portion is rotatable between a first posture in which the sheet that has reached the diverging position is guided toward the sheet discharge portion, and a second posture in which the sheet is guided into the second conveying path. A second movable guiding portion is rotatable between a third posture and a fourth posture, in the second sheet conveying path. In the third posture, the second sheet conveying path is formed in conjunction with the first movable guiding portion. In the fourth posture, the third sheet conveying path is formed.

A system for the automated coating of baked good with a water based icing is provided. In particular, a system for the automated movement of icing and controls of variables such as temperature, moisture, and/or flow rate of the icing is provided to maintain the characteristics of the icing for extended periods of operation of an associated coating system.

An image forming apparatus can create various output products using a transparent sheet as intended by a user.

The invention provides a paper path structure that is able to perform the following four functions: pass a sheet of paper through the paper path structure with is original orientation maintained; pass a sheet of paper through the paper path structure with its original orientation reversed; stack a sheet of paper in a stack repository with its original orientation maintained; and stack a sheet of paper in the stack repository with its original orientation reversed. The invention also provides a method to operate said paper path structure as well as a stacker and a printer comprising said paper path structure.

Provided are systems and methods for identifying, isolating, and/or aligning sheets. An identification system can facilitate accurate identification of a sheet by (i) vacating one or more components of the system that are not the sheet from a zone of detection, and/or (ii) determining a reference axis of the sheet. An isolation system can facilitate accurate isolation of a sheet by (i) providing targeted air flow, and/or (ii) introducing a wave into the sheet. Identification systems and/or isolation systems described herein may facilitate isolation of sheets that were previously fastened together by one or more fasteners. An alignment system can facilitate accurate alignment of a first sheet at an upstream location relative to a second sheet at a downstream location via machine learning.

A sheet-processing machine includes a turning device. Sheets can be conveyed, by a sheet conveyor system, from a sheet guide cylinder in the turning device, and can be conveyed in a sheet conveyor direction on a sheet conveyor path. A sheet guide element is provided beneath or along the sheet conveyor path. A deionization device is assigned to the sheet guide element. The deionization device can provide positive and negative ions.

A sheet conveying device includes a correcting unit. The correcting unit corrects displacement of a sheet conveyed from an upstream side conveying path, and conveys the sheet to a downstream side conveying path. The correcting unit includes a first conveying part conveying the sheet, a first moving part moving a first frame supporting the first conveying part and a detecting part detecting a side end edge of the sheet at a reference position without displacement. The first conveying part stops conveyance of the sheet when a leading end of the sheet reaches the detecting part. While the driving of the first conveying part is stopped, the first moving part moves the first frame to move the sheet, and stops movement of the first frame, when detection result of the detecting part is changed, to position the side end edge to the reference position to correct displacement of the sheet.

According to the present embodiment, a control device of a conveyor system controls a moving device and a suction device to suction the transport target article so that an approximate center of an opening of at least one suction unit is located on a first imaginary line, and remaining suction unit is located on one end side in a longitudinal direction of the transport target article with respect to the first imaginary line, controls a turning-over section to be in a front-back reversing orientation, and performs control so that suction of the transport target article by the suction units is released after the suction device is in the front-back reversing orientation.
