CYLINDER CONSTRUCTION FOR A PRINTING PRESS ABSTRACT OF THE DISCLOSURE A cylinder for a printing press in which the gap for receiving the ends of a plate or blanket is skewed at an angle with respect to an axial length on the surface of such cylinder such that streaking of the printed product as is visible to the human eye is essentially eliminated. Such improved cylinders have a linear skew width greater than the linear gap width with the trailing end of the trailing edge of the gap being located opposite a non-gap area of the other of such cylinders cooperable therewith when such gaps are in their full overlying position. Such improved cylinders have a non-rotative relative motion when the gaps cross over each other such that the cylinders gradually enter into a zone of decreased pressure therebetween and gradually exit from such zone whereby axial deflection of the cylinders is minimized. Such improved cylinder is particu- larly suited for a blanket cylinder, a pair of blanket cylinders or plate cylinders or the well known combinations of blanket and plate cylinders. Further, since the gaps are skewed, a plate or blanket in the form of a parallelogram is provided to improve the mounting of such a plate or blanket to a cylinder having a skewed gap of this invention.
