A method and system for performing sheet registration are disclosed. Output values for a sheet may be identified within a reference frame. A difference between each output value and a corresponding desired output value may be determined. Input values may be determined based on at least the differences. State feedback values may be determined based on information received from one or more sensors. Jerk values may be determined for multiple drive rolls based on the input values and the state feedback values. A desired angular velocity for each drive roll may be determined based on the corresponding jerk value. A motor voltage may be determined for each drive roll that tracks an observed angular velocity value to the desired angular velocity value. The jerk values may create a linear differential relationship between the input values and the output values. The steps may be performed multiple times.

A control system and method for a sheet registration device including a general unit which determines desired contact point velocities for moving a sheet along a reference trajectory. The contact point velocity determination is independent of the sheet registration device. A specific unit is operably connected to the general unit. The specific unit determines registration device specific operating parameters for controlling registration device actuators to move the sheet along the reference trajectory.

An assembly includes two nip assemblies spaced apart along a first axis. Each nip assembly includes a driven wheel and an idler roller. The driven wheel rotatably supported about the first axis. The idler cooperates with the driven wheel to engage a sheet. The idler rotatably supported about a second axis. The second axis being selectively moveable relative to the first axis. The selective movement between a first and second orientation occurs while the sheet is moved along the transport path. In the first orientation the second axis extends parallel to the first axis. In the second orientation the second axis extends at an oblique angle to the first axis. The selective movement pivots about a third axis extending through a centerline common to both the driven wheel and the idler. The selective movement of one of the two nip assemblies being independent from the selective movement of the other.

In a sheet discharge device, sheets are sequentially discharged by a sheet discharge roller with a leading end of each of the sheets in the lead in a sheet discharge direction and stacked on a sheet receiving tray inclining relative to a vertical direction. A sheet reverse member is disposed at such a position relative to the sheet receiving tray and the sheet discharge roller that a trailing end of a first sheet discharged by the sheet discharge roller reaches the sheet reverse member before a leading end of a second sheet discharged subsequently to the first sheet collides with the first sheet when a sheet time interval between the trailing end of the first sheet and the leading end of the second sheet is set to a minimum sheet time interval available in continuous sheet discharge in the sheet discharge device.

A system for conveying mailpieces along a feed path includes a plurality of conveyances. A first conveyance is operative to convey mailpieces along the feed path and includes a singulating and drive belt. The singulating and drive belts define a throat for singulating a mailpiece from the stack of mailpieces. A second conveyance accepts mailpieces from the first conveyance and conveys singulated mailpiece downstream of the first conveyance. The system further includes a series of sensors extending from the first to the second conveyance for issuing a gap signal indicative of the relative spacing between sequential mailpieces along the feed path. Additionally, the system includes a means, responsive to the gap signal, for developing a variable opposing force between the singulating and drive belts to optimize singulation of mailpieces along the feed path.

According to one embodiment, a sheet handling apparatus includes a take-out member to take out a sheet from a take-out position by rotating in a state in which a negative pressure is applied to the sheet at the take-out position and the sheet is adsorbed to the take-out member; a conveyor portion to receive and convey the sheet taken out from the take-out position by the take-out member; and a control portion to control the take-out member such that, when the sheet at the take-out position is being adsorbed to the take-out member, the take-out member is rotated at a circumferential speed that is slower than a conveying speed of the sheet at the conveyor portion, and when the sheet adsorbed to the take-out member is being transferred to the conveyor portion, the take-out member is rotated at a circumferential speed that is the same as a conveying speed of the conveyor portion at that time.

The invention relates to a method and to a device for printing and drying a plastic film web (2), especially a PP, PS, or PE film web, comprising several offset printing mechanisms (10, 12, 14, 16) for printing the film web (2) with different ink applications and at least one flame drying station (18, 20, 22), characterized by a drawing roller (24), which is arranged between a last printing mechanism (16) and the at least one flame drying station (18), contacts the unprinted surface of the film web, and applies tension to the film web.
摘要:
In a mailpiece feed device designed to be mounted upstream from a franking machine, and comprising at least a mailpiece feed zone for receiving a stack of mailpieces supported by a plurality of drive rollers and a separation zone for individually selecting the mailpieces, there are provided control means for varying the speed of rotation of said plurality of drive rollers when, at the outlet of said separation zone, a measurement of a gap between successive mailpieces differs from a predefined gap by a predetermined correction threshold.

The present invention avoids a problem in that wound-up banknotes are located unevenly on substantially the same position on a winding drum. The paper sheet processing device is configured to process paper sheets. The paper sheet processing device includes: a receiving unit configured to receive paper sheets one by one in a predetermined receiving cycle; a transport unit configured to transport the paper sheets received by the receiving unit; a storing and feeding unit including a winding drum that winds up the paper sheets together with a tape, the storing and feeding unit being configured to receive and feed the paper sheets transported by the transport unit, by winding up and winding off the tape; a drive unit configured to drive the receiving unit, the transport unit, and the storing and feeding unit: and a control unit configured to control the drive unit to maintain a tape winding amount per receiving cycle, such that a storing pitch of the paper sheets wound up by the winding drum deviates from a predetermined range relative to an outer peripheral length of the tape wound up by the winding drum.
