Abstract
A rotary screen printing machine has a number of cylindrical stencils each with an internal squeegee and at least one stencil has an impermeable area parallel to the center line of the stencil. The squeegee of the said stencil may be raised or lowered while the impermeable area is in contact with the material being printed such that the printing action may be interrupted during one or more revolutions of the stencil during continuous operation of the printing machine. The stencil will print only when the screen portion is in contact with the material and the squeegee is lowered. A pattern can thus be printed which has a repeat length greater than the circumference of a stencil.
