The device for cooling an adhesive applied to a surface of bag bodies includes a transfer conveyor and a cooling conveyor. The transfer conveyor conveys the bag bodies at a transfer speed to the cooling conveyor, and the cooling conveyor conveys the bag bodies taken over from the transfer conveyor at a cooling conveyor speed. The transfer speed is higher than the cooling conveyor speed, which is why the bag bodies are arranged overlapping each other on the cooling conveyor. Due to this higher packing density, there is achieved a long dwell time of the bag bodies in the cooling conveyor at simultaneously a high flow-rate of bag bodies through the device.

An image forming apparatus includes: a holding body configured to hold a formed image; a conveyance unit configured to convey a recording medium with a leading end of the recording medium gripped by a gripping portion; and a transfer body including a recessed portion that accommodates the gripping portion and is provided along a direction substantially orthogonal to a rotational direction, configured to sandwich the recording medium conveyed by the conveyance unit between the transfer body and the holding body to transfer an image on the holding body to the recording medium conveyed by the conveyance unit, and including a slope surface provided at a leading end of a portion of an outer circumference not including a portion where the recessed portion is provided, the leading end being on a front end side in the rotational direction, a distance from the slope surface to a rotational center becoming larger toward a downstream side in the rotational direction.

A transport device includes a rotating member that rotates; a circulating member that is loop-shaped and wrapped around the rotating member, the circulating member being circulated by rotation of the rotating member; a pair of pinching members attached to the circulating member and circulated together with the circulating member, the pair of pinching members changing from a separated state, in which the pair of pinching members are separated from each other, to a closely positioned state to pinch a transport object that has entered a space between the pair of pinching members in the separated state; and a guide unit positioned to overlap the pair of pinching members in the separated state when viewed in one direction along a rotational axis direction of the rotating member, the guide unit guiding the transport object into the space between the pair of pinching members in the separated state.

To prevent deformation to relatively stiffer sheets during flipping, while ensuring reliable holding of relatively weaker sheets, a method for stacking sheets received from a printer by a sheet flipping device includes at least one slot for receiving a leading portion of a sheet. The method includes determining a respective insertion depth parameter for a first and a second sheet, wherein the second sheet has a greater stiffness than the first sheet; inserting a length of the first sheet into the at least one slot in correspondence with its respective insertion depth parameter, followed by flipping said first sheet; inserting a length (D2) of the second sheet into the at least one slot in correspondence with its respective insertion depth parameter, followed by flipping said second sheet, wherein the inserted length of the first sheet is greater than that of the second sheet.

An apparatus and method for forming a stack with advertising material compilations respectively consisting of an envelope with inserts therein, and having a common, leading folded edge. The apparatus includes a feed conveyor, a transfer conveyor and a stacking device. The transfer conveyor comprises a central wheel that rotates around a first rotational axis, a carrier wheel that rotates around a second rotational axis oriented parallel to the first rotational axis, and a number of pivoting arms with respectively one gripper. The second rotational axis is arranged below a horizontal plane extending through the first rotational axis. The grippers are respectively positioned on the pivoting arm to rotate around an axis. The grippers take over the advertising material compilations in a takeover region from the feed conveyor, transfer the adverting compilations in a transfer region to the stacking device which extends into the transfer region and deposit these on the stacking device.
