Printing magnetic saddle

Claim 1

A magnetic saddle for use in printing which comprises an arcuate and substantially semicylindrical non-magnetic base plate having fibrous layers impregnated with a thermosetting resin, wherein said base plate comprises a plurality of layers of wound fibers including at least one radially inner layer of circumferentially extending fibers and a plurality of outer layers of fibers extending at an oblique angle to the circumference of said base plate, said outer layers alternatingly having fibers angled toward one axial end and toward the other axial end, respectively, of the base plate, said base plate having an outer surface, a plurality of arcuate yokes spaced longitudinally at regular intervals along said outer surface of said base plate and extending circumferentially thereof, said yokes and said base plate being of equal arcuate extent, a plurality of small magnets disposed in the space between adjacent yokes and being spaced circumferentially at regular intervals on the outer surface of the base plate and along each yoke, said magnets being of substantially lesser circumferential extent than the yokes, and a continuous mass of thermosetting resin disposed in the gaps between the magnets and defined by the base plate and yokes to thereby conjoin the foregoing constituent elements.
