The invention relates to a printing blanket assembly for a blanket cylinder of a rotary printing press. The printing blanket assembly comprises a dimensionally stable support plate (02, 18) with two ends, one of which is the forward end and the other one is the trailing end with respect to the rotation of the blanket cylinder, these ends being fastened to the blanket cylinder with folded, printing-blanket free limbs (21, 22). The assembly further comprises a printing blanket (03, 19), fastened to the outside of the support plate (02, 18) and having a forward end (12, 31) and a trailing end (11, 32). Said printing blanket assembly allows for perfect printing also in the area of a gap between the limbs (21, 22) and can be produced in a simple manner. For this purpose, both ends (11, 12; 31, 32) of the printing blanket (03, 19) project beyond the bevelled edge (08, 09; 27, 28) of the pertaining limbs (04, 06; 21, 22) of the support plate (02, 18) and one support element (13, 14; 34, 36) for supporting said projection is disposed between the bevelled edge (08, 09; 27, 28) and the inside of the printing blanket (03, 19).
