摘要： A sheet conveying apparatus includes: a supply unit for supplying a sheet; a first switching unit disposed on a conveyance path of the sheet and configured to switch between a state of nipping the sheet supplied by the supply unit and a state of releasing the nipping of the sheet; a first tension applying unit disposed on one side of the first switching unit in a conveyance direction of the conveyance path and configured to apply tension to the sheet; and a detection unit disposed on the other side of the first switching unit in the conveyance direction of the conveyance path and configured to detect the tension of the sheet, wherein, in a state where the nipping of the sheet is released by the first switching unit, the first tension applying unit adjusts the tension of the sheet while the detection unit detects the tension of the sheet.

摘要： A roll sheet, in which a continuous sheet is wound in a roll form, is caused to rotate in a forward direction to supply the sheet to a printing unit. First and second sensors are arranged at positions facing an outer circumferential surface of the roll sheet and deviated in an axis line direction of the roll sheet. Outputs of the first and second sensors are changed in accordance with a distance to a sheet of the roll sheet. A rotation direction of the roll sheet is switched from a forward direction to a reverse direction on the basis of the outputs of the first and second sensors while the roll sheet is being rotated in the reverse direction.

摘要： A transport control method for use in transporting a medium in a predetermined direction by an upstream drive roller and a downstream drive roller, to operate the downstream drive roller by using PID control based on a detection value of a tension sensor disposed downstream of the upstream drive roller and upstream of the downstream drive roller for detecting tension. The transport control method includes a stable state determining step for determining, at time of the operation, whether a difference between the detection value of the tension sensors and a target value is within a stable width to make a stable state which maintains a stability time; and a gain decreasing step for decreasing a gain of the PID control to be less than an initial value when the difference is determined to be in the stable state.

摘要： The invention relates to a method for adapting at least one winding parameter of a winding device during winding of a film web on a winding core, having the following steps:—conveying of the film web along a measuring path between a first driven roll and a second driven roll—increasing of the web tension of the film web between the first roll and the second roll—continuous detecting of the drive parameters of the first roll and of the second roll at least in the form of the torque and the circumferential speed,—determining of a stress-strain diagram from the detected drive parameters—adapting of at least one winding parameter of the winding device on the basis of the determined stress-strain diagram in order to achieve a defined elongation of the film web during winding on the winding core.

摘要： In a method or device to sample a web movement, an incremental encoder translates the web movement into two phase-offset output signals. A quadrature decoder generates first and second digital output signals with two respective signal levels. The first output signal is designated as a forward signal and the second output signal is designated as a backward signal. An evaluation circuit outputs a control signal and has a first counter that counts a signal change of the forward signal and subtracts from the count a signal change of the backward signal. A second counter counts a signal change of the control signal. A comparator compares values of the first and the second counters. A disabling device enables the forward signal if values of both the first and second counters are the same so that the forward signal is output, and disables the forward signal if values of the two counters are different.

摘要： A mail inserter has a first web driver to move a web from a web supply and a second web driver to feed the web to a cutter for cutting the web into sheets, wherein the first and second web drivers have different velocity profiles to allow a web loop to form between the web drivers. The loop is variable between a maximum size and a minimum size. When the loop reaches the minimum size, the first web driver is running at its maximum speed. At this point the first web driver is decelerated at a rate such that when the first web driver stops, the web loop is at its maximum size. The acceleration of the first web driver is at a constant rate which is inversely proportional to the difference between the maximum loop size and the minimum loop size.

A device is arranged at a first position along a transport path of the printing substrate web, which device supplies a signal to deduce the web tension in effect at the first position or the web tensile force in effect at the first position. A device arithmetically determines the web tension in effect or the web tensile force in effect at the second position from the web tension in effect at the first position or from the web tensile force in effect at the first position as well as from forces, which at least one driven roller and/or at least one trailing roller, which is/are arranged along the transport path of the printing substrate web between the first position and the second position, introduce to the printing substrate web.
