摘要： A method of printing with a rotary printing press having a plurality of printing cylinders that are adapted to be adjusted on and off from a running web, with a length of a printed image being larger than a peripheral length of the largest one of the printing cylinders, the method including the steps of subdividing the printed image into elements, printing these elements with different printing cylinders, and periodically shifting at least one of the printing cylinders off from the web, each time for at least a duration of one turn of the printing cylinder.

摘要： Treatment apparatus for continuous web for producing diecut blanks (for example) has two sets of treatment rolls and the speed of these is adjusted so that although driven at web speed during the treatment portion of each cycle they are accelerated and retarded (or vice versa) during the non-treatment portion of each cycle so as to synchronize the treatment forms on the rolls with the required web areas and avoid wastage. The speed variation is by control of the drive motors for the rolls, but using roll-carried cams connected to gas springs so that energy can be absorbed during retardation and released during acceleration to supplement the motors and thus enable smaller motors to be used.

摘要： A printing machine with several groups of rotary-screen printing units, designed to print different color components of complementary portions of a recurrent pattern on an elongate web moving continuously beneath their screens, includes a programmer such as a perforated-type reader controlling the operation of the several printing units of each group in timed relationship dependent upon the web speed. A speed changer enables the peripheral velocity of the screens to be set at values different from the web speed, the timing of the printing operations being determined by two speed sensors upstream and downstream of the speed changer. These operations include a lowering of the rotating screen onto the web at the beginning of a printing cycle, a lifting of the screen off the web at the end of a working phase of that cycle, and a stoppage of screen rotation during part of the ensuing idling phase. The stoppage is caused by the release of a normally arrested output element of a differential gearing inserted between the speed changer and the drive shaft of each screen.

摘要： A rotary screen printing machine has a plurality of individual rotary screens each having a lifting device. A control element is connected to each of the lifting devices. A drive is operatively connected to the control element to synchronize the rate of rotation of each of the rotary screens and the lifting thereof by the lifting devices.
