摘要:
A corrugated board system comprises a first and a second material supply device for a first or second material web, a corrugated board production device, and a web tension measuring regulating arrangement between the corrugated board production device and the first material supply device. The arrangement comprises a web tension measuring regulating device with a web tension measuring mechanism and a first web tension regulating mechanism, and at least a second web tension regulating mechanism. The web tension measuring regulating device is arranged between the second web tension regulating mechanism and the corrugated board production device. The arrangement furthermore has an information processing unit, which receives web tension information from the web tension measuring mechanism and is configured so that to change the web tension up to a first web tension limit value, it sends web tension regulating signals to the first web tension regulating mechanism and to change the web tension beyond the first web tension limit value, it sends web tension regulating signals to the second web tension regulating mechanism.

A control device controls a processing installation for the production of collections of printed products, wherein the processing installation comprises installation sections (1, 2, 3, 4) which combine input streams (11, 12; 21, 22; 31, 32; 41, 42) of part products into output streams (27, 27a, 37, 37a, 47, 47a) of collections of these part products. Control units are assigned to the installation sections and which, on the basis of a predefined product requirement (Pa2, Pa3, Pa4, Pa21, Pa31, Pa41), activate the assigned installation section for the production of a respective output stream.In each case a control unit (20, 30, 40) is set up to obtain product requirements (Pa2) from the master control (100) or from a different control unit (30), and to produce product requirements (Pa21) for the control unit (10) of an installation section (1) arranged upstream.

A sewing machine system is disclosed that is configured by a sewing machine and a thread spool storage device communicably connected by way of a communication element. The sewing machine is provided with a compartment identifier that searches and finds thread color information pertaining to thread color data contained in the pattern data when a selection of pattern data is validated by a pattern selection validator. The compartment identifier transmits the compartment identification for identifying a location of the compartment of the thread spool storage device that is mapped to the found thread color information. Based on the compartment identification, the thread spool storage indicates the location of the compartment identified by the compartment identification.

A method and system for determining the lateral position of an edge of a web are disclosed. The system includes an array of light transmitting elements and a corresponding array of lenses and an array of light receiving elements and a corresponding array of lenses. The light transmitting elements are each paired with a light receiving element and the light transmitting elements each transmit a beam of light energy towards the corresponding receiving element. The beams of light can be occluded by a web passing between the transmitting elements and the receiving elements, thereby reducing the light received by the receiving elements. The receiving elements can generate a signal that is proportional to the amount of they receive, and a controller can be used to determine the lateral position of an edge of the web in response to the signals generated by the receivers. A compensation light beam can be employed to enable the controller to compensate for several factors that can affect measurement accuracy.

A system for automatically releasing selected plural sheet feeding nip sets spaced along a print media sheet feeding path of a printer, wherein the idler rollers are rotatably mounted on common idler shafts and a selectable partial rotation system driven by a single low cost motor is flexibly connected to those plural idler shafts to partially rotate eccentric lift cams on each idler shaft into the underlying surface as to lift the idler shaft and thereby move the idler rollers away from their normally mating sheet feed rollers to release all the sheet feeding nips, enabling sheet deskew, inversion, acceleration, deceleration, or sheet jam clearance in that selected area of the sheet feeding path.

A printer with donor and receiver media supply trays each adapted to allow a printer to sense type of media therein, and method of assembling the printer and trays. Donor and receiver media supply trays to be loaded into the printer are adapted to allow the printer to sense type of media therein. Each supply tray comprises a tray body having a supply of the media (i.e., donor or receiver) therein. A transceiver is disposed proximate the trays. The transceiver is capable of transmitting a first electromagnetic field and sensing a second electromagnetic field A first transponder is integrally connected to the receiver supply tray and has encoded data previously stored therein indicative of the type of receiver media. A second transponder is integrally connected to the donor supply tray and also has encoded data previously stored therein indicative of the type of donor media. Each transponder is capable of receiving the first electromagnetic field to power the transponder and then generating the second electromagnetic field as the transponder is powered. The second electromagnetic field is characteristic of the data previously stored in the transponder and is indicative of type of media contained within the tray. Data stored in the receiver tray transponder attached to the receiver supply tray is necessarily different from data stored in the donor tray transponder. The printer then operates in accordance with the data sensed by the transceiver to produce quality prints consistent with the type of donor and receiver being used.

Device for controlling with adjusting members and a measuring device the lateral position of a web in a web printing machine, the controlling device, for effecting centralized control, having respective optical scanning systems for detecting edges of the web on both sides thereof and the respective positions of the edges and, upon lateral shifting of the web, activating the adjusting members for correcting the position of the web in accordance with a nominal value, including a respective bandpass filter connected to each of the optical scanning systems, and means for detecting a long-term change in the control signal by the bandpass filter of one of the optical scanning systems, the one optical scanning system being in position yet being idle with respect to controlling the lateral position of the web, the other optical scanning system being active with respect to scanning the respective web edge for controlling the lateral position of the web, the detection of the long-term change in the control signal by the bandpass filter of the one optical scanning system being an indication of fouling of the optical scanning systems, whereby compensation for the fouling may be effected.
摘要:
A relay conveyance device detachably mounted on an image forming apparatus body is provided with a fixing member that holds a mounting state of the relay conveyance device to the image forming apparatus body. The fixing member is provided with a relay connector that relays the image forming apparatus body and the post-processing device. The post-processing device is electrically connected to the image forming apparatus body via the relay connector.
摘要:
An image forming apparatus having a main body and optional trays and a communication method between the main body. optional trays. The apparatus includes the main body having a main controller, at least one optional tray detachably set up in the main body and having a tray controller for communicating with the main controller to transmit and receive data, and communication lines forming a communication channel connecting the main controller and the tray controllers, for data exchange, and for informing the main controller that the data is provided from tray controllers to the main controller. Since the main body and the optional trays communicate through a single UART communication channel, the number of communication channels is decreased.
