Abstract
197,751. Evans, A. B. Feb. 23, 1922. Printing-surfaces,. blankets.-Flexible printing- plates, blankets, or the like, are secured in small gaps in the cylinder by means of radially movable tensioning-members fitted with means for engaging laterally projecting fittings secured to the ends of printing-plates &c., preferably in registered relation to the designs on such printing- plates. As shown in Fig. 1, a plate b is drilled at each end with holes to which are secured bolts d by means of nuts e, or the bolts may be riveted to the stiffening pieces f as shown at the right side of Fig. 1. The bolt heads are received in undercut recesses h formed in a bar g which is mounted on tensioning-screws c which are adjustable radially of the cylinder a, springs k being arranged to support the bar g on the screws c. The bar g may extend right across the cylinder or it may be divided into sections. In some cases it is formed of two parts, as shown in Fig. 3, the recesses h of which receive bolts on opposite ends of the plates, the two parts being independently adjustable. In a further modification, Fig. 6, a stiffening piece f is riveted to the plate b and the tensioning- member l is rotatable on the screw c bv a spanner, and is formed with a wedge-shaped under part l<1> which engages the 'bar f directly, and acts as a cam to move the piece f to effect the tensioning. The member l is rotated a quarter of a turn to apply the tension. - In a further form each end of the plate b is formed with a bar f and one member l engages both bars f, and simultaneously applies tension to both ends of a plate.
