Abstract
A method and apparatus are disclosed wherein a signal proportional to the speed of a moving web is compared with a signal proportional to the speed of a motor driven rotary, printing member, and a resultant corrective signal is transmitted to the control for the motor, so that the linear speed of the rotary printing member is made equal to the web speed. A plurality of printing members are provided so that the linear speed of each of the printing members is made equal to the web speed and in synchronization one with the other. The method and apparatus as aforesaid are specifically adaptable for rotary screen printing of fabrics, wherein the fabric contactingly engages a plurality of rotating screens in series, and a color is passed through each screen in selected predetermined areas, so that the composite screen printings provides a repetitive design on the fabric.
