In some examples, a sheet processing machine includes at least one transport means of an infeed system, and the infeed system includes at least one cam mechanism including, in each case, at least one cam disk having an axis of rotation. At least one scanning element is arranged in each case to rest against the at least one cam disk. The at least one scanning element is connected to the at least one transport means via at least one drive lever. The at least one drive lever in each case has at least one mounting point. The mounting point and the axis of rotation may be adjusted relative to one another, and a position displacement of the mounting point relative to the axis of rotation may compensate for at least one position error of the at least one sheet.

A cassette comprises a storage portion configured to include a loading surface on which a sheet is loaded, a sheet guide configured to pivot with respect to a pivot central axis that is parallel to the loading surface, a pivot support shaft extending on two sides of the sheet guide along the pivot central axis, in the sheet guide, and a bearing portion configured to pivotably support the pivot support shaft, an insertion portion formed at a portion of the pivot support shaft, an insertion groove formed from the loading surface toward the bearing portion, and a flexible pressing portion disposed outside the insertion groove, and configured to press a leading end portion of the pivot support shaft.

In some examples, a sheet processing machine includes at least one pile formation device. The at least one pile formation device is arranged in a vertical direction beneath a multiple-up separating mechanism. The at least one pile formation device is arranged so as to be displaceable at least in an inward-moving direction. The at least one pile formation device includes at least one horizontally displaceable pile formation means and a deposit element that can be displaced relative to the at least one pile formation means.

In an example, a clamp may include a chassis, a swingarm disposed on the chassis, a clamp wheel disposed on a first end of the swingarm to engage with a drag portion of the chassis, and an auxiliary bias member to exert a force against the clamp wheel to resist a rotation of the clamp wheel. The force may periodically increase in magnitude.

The force may periodically increase in magnitude.

A sheet conveying device includes a tray, a conveyor, and a guide body. The tray is configured to stack a sheet. The conveyor is configured to convey the sheet to the tray. The guide body has a space, a height of the space being greater than a thickness of the sheet. The guide body is configured to guide the sheet conveyed by the conveyor, with a leading end of the sheet being inserted in the space. The guide body is configured to separate the sheet from the space, according to a difference of a sheet conveying speed of the conveyor and a moving speed of the guide body, and to stack the sheet on the tray.

A sheet stacker includes a tray to store a stack of sheets, a conveyor above the tray, a leading end guide above the tray, and an air exhaust. The conveyor conveys a sheet in a conveyance direction. The leading end guide is downstream from the conveyor in the conveyance direction. The leading end guide guides the sheet from the conveyor to the tray. The air exhaust exhausts air above an upper surface of the stack of sheets on the tray to an upstream from the tray in the conveyance direction. Further, the leading end guide holds a leading end of the sheet conveyed by the conveyor at a holding position and releases the leading end of the sheet at a release position downstream from the holding position in the conveyance 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.

In some examples, a die-cutting machine includes a transport system configured as a chain gripper system. The chain gripper system includes a chain gripper carriage including a holding element for holding a sheet. The chain gripper carriage is arranged to be attached to at least one chain that is arranged to guide the chain gripper carriage on a guide path through at least part of the die-cutting machine. The chain gripper carriage includes a contact element functionally connected to the holding element. A chain gripper opener includes a contact surface at which, in the presence of the gripper carriage at the contact surface, the contact element cooperates with the chain gripper opener. The holding element is transferred at least from a closed position into an open position by cooperation of the chain gripper opener with the contact element. The chain gripper opener is adjustable by at least one drive.

A conveyance mechanism includes: a lower conveyance guide disposed below an inclined conveyance path having an upward inclination or a downward inclination with which a sheet material is to be conveyed, and to guide a lower surface of the sheet material; an upper conveyance guide located above the inclined conveyance path, and to guide an upper surface of the sheet-shaped material, the upper conveyance guide being openable and closable about a rotation shaft, which is disposed on a side of the inclined conveyance path in a direction of a width of the inclined conveyance path so as to extend along the inclined conveyance path; and a first urging member to urge a portion of the upper conveyance guide away from the rotation shaft in the direction of the width of the inclined conveyance path toward the rotation shaft, the portion of the upper conveyance guide away from the rotation shaft being at an upper end of the upper conveyance guide in an inclined direction.
