Abstract
A blanket cylinder used in offset lithography includes a cylinder body, a retainer spindle and a resilient member. The cylinder body has an undercut groove with a first undercut longitudinal edge for engaging a first flange of a carrier sheet and a second undercut longitudinal edge for temporarily engaging a rim of the carrier sheet. The retainer spindle is received in the undercut groove for bi-directional rotation. The retainer spindle includes a pull-in hook that engages the rim of the carrier sheet to pull a second end portion thereof into the undercut groove with rotation of the retainer spindle in a first direction and a push-out ledge abuts against the rim of the carrier sheet in order to push a second end portion thereof out of the undercut groove with rotation of the retainer spindle in a second direction. The resilient member energizes the retainer spindle in the first direction.
