Filed:

Oct 27, 2000

Appl. No.:

09/699195

Inventors:

Michael T. Dobbertin - Honeoye NY
John A. Winterberger - Spencerport NY

Assignee:

Heidelberger Druckmaschinen AG - Heidelberg

International Classification:

G03G 1500

US Classification:

399388, 399389, 399396

Abstract:

An apparatus and method for moving a receiver having a lead edge and a trailing edge from an upstream engaging nip into registered relationship with an image-bearing member moving at an image-bearing member speed. A motor, a drive member operable to engage the receiver, and a drive coupling connecting the motor with the drive member are provided. A controller drives the motor in accordance with a velocity profile if the receiver is of a predetermined optimal receiver length, and drives the motor in accordance with a second velocity profile if the receiver is longer than the predetermined optimal receiver length.

Heidelberger Druckmashinen AG - Heidelberg

International Classification:

B65H 312

US Classification:

271 90

Abstract:

A method of operating a vacuum corrugated belt feeder, which may or may not have a positive air pressure separator, during non-feed cycle time. âThe result beingâ to separate a sheet from a sheet supply stack, which method comprises agitating the top sheets in the stack by actuating the vacuum and/or the positive air pressure separator during non-feed cycle time.

Assignee:

Heidelberger Druckmaschinen AG - Heidelberg

International Classification:

G05B 1101

US Classification:

318560, 271 315

Abstract:

An apparatus and method for moving a receiver into a registered relationship with a moving image-bearing member in a registration mechanism. The apparatus and method account for receivers that arrive at the registration mechanism outside a normal operating time window. When a receiver arrives too late, the receiver is accelerated to a speed greater than that of the moving image-bearing member for a period of time sufficient to account for the arrival delay. The receiver is then decelerated to a speed substantially equal to that of the image-bearing member. When a receiver arrives too early, the receiver is brought to a stop for a period of time sufficient to account for the early arrival. The receiver is then accelerated to the image-bearing member speed.

Appl. No.:

09/751193

Inventors:

Michael T. Dobbertin - Honeoye NY
James G. Amorese - Webster NY

Assignee:

Heidelberger Druckmaschinen AG - Heidelberg

International Classification:

B65H 108

US Classification:

271148

Abstract:

A leveling device is useful for paper having at least two different thicknesses for a paper supply tray having a given depth, for a sheet feeder. This leveling device comprises a support upon which the paper having at least two different thicknesses rests, wherein the support height is self adjusting to compensate for the different thicknesses of the paper such that a top sheet of paper is in a position to feed properly into the sheet feeder.

International Classification:

B65H 900

US Classification:

271226, 271270, 271264, 27126501, 399396

Abstract:

An apparatus and method for advancing a receiver into registered relationship with a moving image-bearing member. A motor is provided that is responsive to motor drive pulses. A drive member engages the receiver, and a drive coupling connects the drive member and the motor. An encoder generates encoder pulses that correspond with movement of the image-bearing member. A pulse generator generates motor drive pulses in response to the encoder pulses to accelerate the receiver to a speed approximately equal to the speed of the image-bearing member speed. A timer determines an amount of delay time between detection of the receiver by an in-track sensor and the beginning of a subsequent movement of the motor. A delay mechanism delays the acceleration of the receiver to the image-bearing member speed by the amount of delay time.

International Classification:

B65H 108

US Classification:

271 301, 271147, 271152, 271157

Abstract:

A system and method for providing the ability to more effectively control a paper stack in a reproduction apparatus. The level control behavior of the paper stack is characterized, and accordingly, additional lift commands are signaled when the behavior indicates that such increments are necessary. The behavior is characterized by sampling data during a sampling period including switch initiated increments. Upon characterization, additional increments are initiated by a source other than the switch initiated increments to more effectively control the paper stack.

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G03G 1500

US Classification:

399394

Abstract:

An image-production system includes a marking engine. The image-forming production system may also include an inserter. The marking engine includes a marking engine controller, a speed adjust system and a registration system. The registration system aligns sheets going to an imaging unit. The speed adjust system controller includes a speed adjust system controller. When at least one sheet approaches the speed adjust system, the marking engine controller transmits a synch pulse signal to the speed adjust system controller. The speed adjust system transmits a signal to the speed adjust system controller of the arrival time of the at least one sheet. The speed adjust system compares the measured arrival time with the synch pulse signal to adjust a speed and timing of the sheet before the sheet is transferred to the registration system.
