Abstract
A disklike rotary switch is installed at a junction of four web-threading guideways in a rotary printing press, for use in switching a web, being threaded through the press preparatory to printing, from one to another of the guideways. The web-threading guideways are of radial arrangement, constantly spaced 45 degrees from one another, about the axis of rotation of the switch. The switch has defined therein two orthogonally intersecting, rectilinear switching guideways, each for intercommunicating one pair of web-threading guideways opposed to each other across the switch, and two arcuate switching guideways each for intercommunicating two of the web-threading guideways that are adjacent each other circumferentially of the switch. A single fluid-actuated cylinder is used for driving the switch between two preassigned angular positions. A tandem connection of two such cylinders is used in an alternative embodiment for driving the switch between three positions.
