A forming assembly of multilayer packets of wet wipes includes: a feeding device of wipes assemblies; a forming device of packets including wipes assemblies; a packet removing device, where the forming device receives the wipes assemblies from an upper level and releases the packets at a lower level; first and second bands closed in a loop, moving along a path having a respective operating section extending vertically, including blades facing one another along the respective operating section creating housings for single wipes assemblies and defining a free space; a moving index in the free space ejecting a predetermined number of wipes assemblies onto the removing device; and a movement member advancing the index through the free space, the index including a fixed body associated with the movement member and a moving portion associated with the fixed body, allowing the index height to vary with respect to the removing device.

A three side trimmer has a trimming unit 1, an accumulating unit 3, a discharge unit 2 and a conveying mechanism 4 conveying trimmed booklets BK to the accumulating unit. The accumulating unit has a shelf 5 movable in a vertical direction, and a drive roller conveyor 7 on the shelf. The accumulating unit, in a mode, delivers the trimmed booklets to the discharge unit at every accumulation of a predetermined number of the trimmed booklets and, in another mode, accumulates the trimmed booklets without delivering.

A machine for folding, cutting, and stacking napkins is provided. The machine has a feeding station, at least one pair of folding rollers pivoting about horizontal rotational axes, a blade, and a pair of spacers having fingers configured to support the napkins stably downstream of the blade, with respect to a horizontal plane perpendicular to a direction of travel, the folding rollers being provided with circumferential slots for inserting the spacers.

A sheet bundle discharging apparatus K, including: a conveyance unit 66 configured to convey a sheet bundle; a guide unit 72 configured to guide the sheet bundle conveyed by the conveyance unit; a discharging unit 90 configured to discharge the sheet bundle to an outside of the sheet bundle discharging apparatus; and a receiving unit 81 configured to receive the sheet bundle guided by the guide unit, wherein the receiving unit includes: a contact portion 81c with which a leading end portion of the sheet bundle, which is guided by the guide unit, in a moving direction of the sheet bundle is to be brought into contact; and a pushing portion 81b, which is formed integrally with the contact portion, and is configured to push a first surface of the sheet bundle, and wherein the receiving unit is rotatable between a first position and a second position, and is configured to receive the sheet bundle in the first position and rotate from the first position to the second position, thereby allowing the pushing portion to push the first surface of the sheet bundle to place a second surface of the sheet bundle, which is on a side opposite to the first surface, on the discharging unit.

A sheet bundle discharging apparatus, including: a guide unit configured to guide a sheet bundle with a spine as a leading end; a receiving unit configured to receive the spine of the sheet bundle guided by the guide unit; and a discharging unit configured to discharge the sheet bundle, wherein the receiving unit includes: a first surface configured to receive the spine at a first position; a second surface configured to push the sheet bundle in a rotation direction of the receiving unit; and a third surface configured to regulate a movement of the sheet bundle in the rotation direction while the receiving unit rotates from the first position to a second position, and wherein a friction coefficient between the sheet bundle and the third surface in a direction away from the first surface is larger than a friction coefficient between the first surface and the sheet bundle.

A sheet stacking apparatus includes: a sheet stacker capable of stacking a sheet; a sheet conveyer that conveys the sheet to the sheet stacker; an openable member that can be opened/closed at time of taking out the sheet stacked on the sheet stacker; and a hardware processor that controls the sheet conveyer so as to convey the sheet to the sheet stacker in a case where an opened/closed state of the openable member is an intermediate state between a fully-opened state and a fully-closed state.

A sheet stacking system includes a conveyor for carrying sheets from a conveyor intake end to a conveyor discharge end and a hopper at the discharge end for receiving the sheets and guiding them as they fall in a cascade path onto a platform. The hopper has a backstop facing the discharge end of the conveyor and a first accumulator that includes a carrier and a support extending from the carrier through the backstop. The support is configured to rotate from a retracted position to an extended position relative to the backstop, and the carrier is movable linearly and vertically relative to the backstop with the support in the extended position from a raised location with the support outside the cascade path to a lowered location with the support in the cascade path.

An image forming system includes an image forming apparatus and a stacker that includes a discharged paper storage and a transporter, the discharged paper storage storing a sheet discharged from the image forming apparatus, and the transporter transporting the sheet to the discharged paper storage, wherein the image forming apparatus includes: an image former that forms an image on the sheet designated for a job and generates printed matter; and a hardware processor that performs control to cause the transporter to discharge a buffer sheet to the discharged paper storage, in which the printed matter is not discharged, before the job is executed, and that executes the job after the buffer sheet transported through the transporter is stored in the discharged paper storage to cause the transporter to transport the printed matter, which is generated by the image former, and cause the discharged paper storage to store the printed matter.
