ABSTRACT:
A blanket bar assembly for use on a printing blanket comprising a U-shaped bar having a centrally located channel and two arms extending outwardly from the channel in a substantially parallel relationship. Inwardly directed projections are provided on one or both arms and are directly aligned with holes on the opposite arm or arms. The projections are of such a length so as to be capable of extending through the holes and be deformed so as to lock the arms together. A printing blanket edge inserted into the channel and pierced by the projections is thereby securely fastened to the blanket bar.
