Guide apparatus for copy masters

摘要

In a guide apparatus for a copy master, guide elements are provided which define a transport plane of the copy master and which comprise lateral walls located essentially perpendicular to the plane of transport of the master and approximately parallel to the direction of copy master transport. The lateral walls guide the lateral edges of the copy master. A detector is further provided to detect the information applied near lateral edges of the copy master. The lateral walls of the guide apparatus are laterally adjustable in case of variations of the width of the copy master in the plane of transport.
