A lock-up mechanism for holding printing blankets to printing cylinders in rotary presses, which eliminates the problem of blanket pullout. The lock-up mechanism includes a substantially planar surface on a reel rod, running from the inner edge of the axial groove to a point on the reel rod circumference on the opposite side of the reel rod center. The substantially planar surface forms an angle with the inner edge of the reel rod groove and the surface of from about 85 DEG to about 97 DEG , preferably about 90 DEG . The configuration eliminates blanket pullout by redirecting the forces applied to the blanket to a direction where the forces do not tend to pull the blanket out of the groove. The lock-up mechanism can be used in any printing cylinder, but most preferably in narrow gap type cylinders.
