A pair of regulating guides can guide both end edges in a sheet width direction Y of a sheet being conveyed being nipped by a conveying belt and balls. The pair of regulating guides can move to their respective guide positions each for guiding one of both end edges of the sheet and their respective retracting positions each retracting from one of the both end edges of the sheet by a distance larger than the guide position. A guide moving unit for moving the pair of regulating guides makes each of the pair of regulating guides reach the guide position from the retracting position after the rear end of the sheet passed from a conveying roller pair positioned on the upstream side to the conveying belt passes the conveying roller pair.

A trolley device is used to convey laminar elements. The trolley device includes at least one belt that defines a closed loop, a plurality of pulleys, at least one drive pulley being configured to act on the belt, the pulleys being mounted on a frame with a supporting region over which a section of the belt can be slid and wherein suction means linked to the belt are provided. The belt includes at least on the outer face thereof a projecting section of predetermined length that protrudes in height with respect to the rest of the belt, the projecting section being provided with a plurality of through holes aligned in position with through holes made in the belt.

A cardboard dispensing apparatus for providing cardboards at a food product supply area comprises a cardboard store for storing cardboards that form a cardboard stack, a cardboard buffer storage for storing a plurality of cardboards, and a cardboard conveyor for conveying the cardboards from the cardboard buffer storage to the food product supply area. A cardboard extracting device is configured to extract cardboards from the cardboard store and move the cardboards into the cardboard buffer storage, while the cardboard conveyor is configured to remove the cardboards from the cardboard buffer storage and convey them to the food product supply area.

A destacking system for cardboard blanks comprises a deposition unit for cardboard blanks with first and second deposition positions, a first destacker comprising a first stacking magazine for accommodating a first stack of cardboard blanks, a first retaining system for retaining the cardboard blanks at a first stacking position, and a first conveying unit with a first gripper to grip a first cardboard blank of the first destacker at the first stacking position and convey the first cardboard blank to the first deposition position, a second destacker comprising a second stacking magazine for accommodating a second stack of cardboard blanks, a second retaining system for retaining the cardboard blanks at a second stacking position, and a second conveying unit with a second gripper configured to grip a second cardboard blank of the second destacker at the second stacking position and convey the second cardboard blank to the second deposition position.

The apparatus (100) for realising a cardboard strip for packaging comprises: a store (M), for a stack (P) of cardboard sheets (C); gripping means (4), for picking up a cardboard sheet (F1) from the stack (P) and for positioning the second cardboard sheet (F1) on the first support (1) for the application of adhesive material; transfer means (6), for transferring the first cardboard sheet (F1) towards the second support (2), so that the first cardboard sheet (F1) is rested on the second support (2) with an end portion (E) thereof with the adhesive material projecting towards the store (M) and towards a third support (3).

The third support (3) is activatable into a raised configuration (S), to raise an end portion of a second cardboard sheet coming from the store and into a lowered configuration (A) so as to lower the end portion (E2) of the second sheet (F2) and position it at the end portion of the first sheet (F1). Pressor means (7) are activated transversally to the two sheets (F1, F2) so as to press the two superposed end portions (E, E2) of the two sheets (F1, F2) in order to fix the end portions (E, E2) to one another to form a cardboard strip (NC).

A sheet conveying apparatus for conveying a sheet in a conveying direction includes a pair of conveying rollers receiving and conveying a sheet; an endless conveying belt conveying the sheet; a plurality of balls to be rotatable in any direction while nipping the sheet with the conveying surface; a pair of regulating guides disposed on both sides of the conveying belt; a guide moving unit that moves the pair of regulating guides; and a roller moving unit that moves at least one of the pair of conveying rollers to a nip position and a nip release position. Before a rear end of the sheet passes the pair of conveying rollers, the pair of conveying rollers is moved to the nip release position by the roller moving unit, and then, the guide moving unit makes each of the pair of regulating guides reach the guide position from the retracting position.

In some examples, a printing press includes a support element with a circulatingly movable contact surface for contacting a printing substrate. An ink jet print head includes an ejection opening arranged to be directed at the support element. Additionally, the printing press includes a charging device that includes a charging electrode, which is arranged to be directed at the contact surface. The charging device further includes a counter-electrode, and the movable contact surface is at least partially arranged between the charging electrode and the counter-electrode of the charging device. A smallest distance between the charging electrode and the movable contact surface is greater than a smallest distance between the ejection opening of the ink jet print head and the contact surface. For example, the smallest distance between the charging electrode and the contact surface may be at least 50 mm.

A carton handling system for a carton blank magazine. The carton handling system includes a carriage assembly with a carton handling tool. The carriage assembly moves the carton handling tool in two axes of motion to receive a slug of carton blanks and to position the slug of carton blanks in the carton blank magazine. The carton handling system further includes a finger carried on the carton handling tool. The carton handling tool is movable to engage the finger with an underside of a fallen carton blank lying at an end of an advancing stack of blanks in the carton blank magazine so as to lift the fallen carton blank against a preceding blank at the end of the advancing stack of blanks. The carton handling tool is also movable to position the slug of carton blanks at an endmost blank in the advancing stack of blanks.

The present invention includes a lift portion lifting and inverting a sheet group including a plurality of stacked sheets and a conveyor portion that moves, along a conveying direction, each sheet transferred from the lift portion, wherein: the lift portion includes frames, a fork portion, an inversion mechanism turning the fork portion to lift and invert the sheet group, and a fork movement mechanism moving the fork portion; the lift portion is equipped with a width direction movement mechanism moving the sheet group in a width direction; and after the sheet group is mounted on the fork portion and before the sheet group is transferred to the conveyor portion, the width direction movement mechanism is controlled on the basis of detection information from a position sensor to center the sheet group within a reference width direction range.
