    摘要: A web printing system automatically detects the location of a wrinkle in a moving web. The web has a plurality of marked reference positions including an inboard position, a center position, and an outboard position. A plurality of contact image sensors detect the reference positions after the web passes through a spreader and an inboard distance and an outboard distance are respectively measured from the center position. If the inboard distance is less than a nominal inboard distance, the wrinkle is identified as inboard of the center position. If the outboard distance is less than a nominal outboard distance, the wrinkle is identified as outboard of the center position. The machine operator is notified of the fault condition and takes action to remedy the situation.

    摘要: A method is used to set a contact pressure between a displaceable roller and another roller or for moving the displaceable roller with respect to the other roller. At least one actuator is subjectible to the action of a pressure medium and presses the displaceable roller toward the other roller with an adjustable force. The pressure of the pressure medium can be adjusted by a valve. A switchover device is provided for use in connecting the valve to different actuators, as desired.

    摘要: A process is provided for printing a graphic image onto a cue sports cloth to form a cloth layout including a bed cloth and cushion cloths. The process comprises supplying the desired dimensions of the bed cloth and cushion cloths to a digital computer, accessing a digital image, and scaling and dividing the digital image to enable the image to be printed onto a cloth, with part of the image on the bed cloth and part of the image on at least one of the cushion cloths. The image is then printed onto the cloth using a digital printing apparatus and suitable inks to create a piece of printed cloth having on it a series of image portions making up the bed cloth and the cushions. When separated and fitted to the cue sports table, the bed cloth and cushion cloths co-ordinate to create a printed image having a portion of the said image on the bed cloth and a co-ordinating portion of the image on at least one cushion cloth.

    摘要: The device has a sheet-transfer cylinder (2) with a movable setting plate (3) which bears the sheet grippers (4) and whose lateral ends are individually adjustable during each revolution of the transfer cylinder (2) with the aid in each case of a roller lever (9) in the circumferential direction in such a way that the sheet transferred to the impression cylinder is in a position which corresponds to the precise printing register. For this purpose, each roller lever (9) mounted movably on the transfer cylinder (2) is guided in a guide path (15c), surrounding the cylinder axis (1) in an annular manner, of an actuator (15, 16) which is suspended pivotably above the cylinder axis (1). Said actuator is provided with individually adjustable stops (19a, 19b) which, by interaction with peripheral cams (24a to 24d) pivot the relevant actuator (15, 16) by a predeterminable amount during each revolution of the transfer cylinder (2) and thus displace the relevant end of the setting plate (3).
