The present application relates to a mail processing system and related method containing dynamic speed control which uses real time and historical system parameters to dynamically control the cycle speed of an inserting or wrapping system to optimize system efficiency, and maximize throughput and performance. A document processing system with dynamic speed control analyzes system parameters. When the operational conditions are favorable the system will increase cycle speed of one or more of the mail processing components of the system in increments until an optimal speed is reached. Likewise, if conditions are unfavorable the system will decrease cycle speed of one or more of the mail processing components of the system in increments until an optimal speed is reached.

An apparatus is disclosed for reducing feed rate variations when unwinding a web material. The apparatus includes a rotational position and speed determining device for determining the rotational position and speed of the parent roll, a drive system for imparting rotational movement to the parent roll, a device for measuring the radius of the parent roll, and a logic device. The logic device generates an ideal speed reference signal and utilizes calculated and measured data to establish a corrected speed reference signal to make adjustments in the driving speed based upon the corrected speed reference signal to maintain a relatively constant feed rate. By dividing the parent roll into 1, 2, . . . n sectors, the data can be refined to a relatively high degree taking into account high speed data processing capabilities as well as operating system response times to make appropriate driving speed adjustments.

A sheet conveying device that makes it possible to perform printing at high speed with high accuracy by easily correcting skew of a sheet, such as an index tab sheet, without requiring troublesome operations. Sheet detection sensors for detecting a sheet and skew correction rollers for conveying the sheet are disposed in a direction crosswise to a conveying direction of the sheet. A skew correction drive controller measures a leading edge detection time between respective detections of a leading edge of the sheet by the sensors, and controls the conveying speeds of the skew correction rollers independently of each other such that a skew represented by the leading edge detection time is corrected. If the leading edge detection time is not smaller than a predetermined threshold value, the skew correction drive controller reduces a skew correction amount for correcting the skew by a predetermined amount.
