ABSTRACT:
A guide system for arranging a plurality of print wires from a converging arrangement into a parallel arrangement aligned with a column of dot locations to be printed on a record medium, the guide system including a first guide more remote from the record for bearing against the wires as they are bent into a direction perpendicular to the record medium. And a second guide nearer the record medium than is the first guide, for applying the bending force to the wires to bring them into alignment perpendicular to the record medium. A final guide still nearer to the record medium finally assures that the wires are in a straight, columnar line as they face the record medium. The first and second guides are freely movable in a plane substantially perpendicular to the final direction of movement of the wires, thereby accommodating some transient movement of the wire ends and to accommodate unbalanced bending forces of the wires due to an unequal number of wires approaching the guide from each side of the axis of movement of the wire ends.
