A method and a device combine auxiliary and main stacks in a delivery or feeder of a machine for processing printing materials. The device includes a rake that can be moved in and out between the main and auxiliary stacks by a motor drive. A control computer controls the motor drive of the rake. Different speed profiles are stored in the control computer for the drive of the rake as a function of the printing materials in the stacks. A sheet-fed offset printing press having the device is also provided.

Method and device for combining auxiliary and main stacks in a delivery or feeder of a machine for processing printing materials and sheet-fed offset printing press having the device

A method for synchronizing the motion sequences of at least one main pile and at least one auxiliary pile in a feeder or delivery device of a printing material processing machine () having the following features: a drive () for moving the main pile () and a main pile controller () associated with the drive (), an additional drive () for moving the auxiliary pile () and an auxiliary pile controller () associated with the additional drive (). The auxiliary pile controller () receives from main pile controller () or from a further, higher-level machine controller () a start signal to move the auxiliary pile (), the start signal simultaneously initiating a movement of the main pile (). A related device is provided.

Method for synchronizing the main pile and the auxiliary pile

An apparatus for picking up an auxiliary pile during a renewal of a main sheet pile when feeding sheets to a printing machine. The apparatus has loadbearing elements arranged on a holder for the auxiliary pile, and a positioning device for the loadbearing elements under the auxiliary pile. The loadbearing elements are flexible with respect to positioning forces acting from outside.

A machine for processing flat printing material, in particular a sheet processing rotary printing press, includes at least one processing station in the form of a printing unit, a feeder for loading the processing station with sheets of the printing material, a delivery for combining the processed sheets into piles, and an auxiliary pile carrier displaceable in an insertion direction from a standby position into an operational position and vice versa. Supporting members follow one another in the insertion direction and axially parallel swivel joints articulatingly connect the supporting members directly to one another. The supporting members have extensions projecting beyond the swivel joints thereof. One of the extensions directed counter to the insertion direction of a respective one of the supporting members engages underneath one of the extensions directed in the insertion direction of the respective supporting member after the next which trails in the insertion direction.

A flexible bearing bar includes a flexurally soft tensile member carrying, on one side thereof, a multiplicity of compressive elements disposed successively in series and formed with respective contact surfaces, said tensile member being supportable on two supports, and said contact surfaces being subjectible to a load acting between said supports, from said compressive elements in a direction towards said tensile member for keeping said contact surfaces, respectively, in contact with one another.

Flexible bearing bar for accommodating a sheet pile in a sheet-processing machine

A device for handling a sheet pile in a printing press includes a pile chamber with at least one opening of a size at least through which the pile is passable horizontally, a lifting platform in the pile chamber for receiving the sheet pile thereon, a lift drive for vertically adjusting the platform, and a screen assigned to the opening and adjustable between a first operating condition wherein the screen covers the opening, and a second operating condition wherein the opening is free from being covered by the screen. A conveyor section horizontally shifts the pile through the opening when the lifting platform is at a transfer level. The conveyor section includes a first conveyor subsection within the pile chamber and at least a second conveyor subsection outside and adjoining the pile chamber. The first and second subsections have alternating states of occupancy during operation. They are alternately occupied by a pile and not occupied by a pile. A conveyor section drive shifts the pile along the conveyor section. The screen is operationally independently changeable from the first to the second operating state for predetermined states of occupancy of the conveyor subsection and when the lifting platform is at the transfer level and, the screen is operationally independently changeable from the second to the first operating state thereof after the pile has been shifted completely from one of the conveyor subsections to the other.
