ABSTRACT:
A pin bar 10 for mounting flexographic printing plates 25 on print cylinders 20 is formed as an angle bar 11 having two pairs of bearing regions spaced apart on two parallel lines near the bar edges 14 so that the bearing regions can all engage the cylindrical print surface of a print cylinder to align the bar parallel with the axis 21 of the engaged cylinder. Pins 40 for mounting the plate are axially movable in a slot 50 that extends parallel with the lines for the bearing regions. A set screw 45 holds each of the alignment pins 40 in a selected axial position in slot 50, and a clamp on each end of the bar includes a chain 36 that can wrap under a cylinder shaft 24 and be tensioned by a screw 30 and a hand nut 31 for holding bar 10 firmly in position on cylinder 20.
