Rubber blanket for a printing machine

Printing group for a color-printing web-fed rotary press

A rubber blanket unit is structured having an underlying support plate with angled end legs, and an overlying rubber blanket with leading and trailing ends. The rubber blanket unit is secured to a blanket cylinder by insertion of the end legs into a thin cylinder slit. The rubber blanket ends are formed each having a reduced thickness and each further having a closure element. The leading and trailing blanket end closures cooperate to form an essentially seamless rubber blanket when the blanket unit is in place. The blanket ends are not dislodged by mechanical or chemical cleaning.

A plate end of a flexible printing plate is released or ejected from a narrow slit in the surface of a plate cylinder. A rotatable spindle is situated adjacent a radial inner end of the cylinder slit. This spindle carries a group of resilient ejectors having free ends that are engageable with the plate ends during rotation of the spindle and which push the plate ends out of the narrow cylinder slit.

Device for releasing plates from a cylinder

A paper supply roll leading edge securement, which is usable particularly during a flying roll change, utilizes an adhesive having sensor detectable constituents. This adhesive can be applied to or across the leading edge of the first layer of the paper web on the supply roll. The use of the sensor detectable constituents facilitates proper positioning of the paper supply roll and helps separate faulty products from the production stream.

A plate clamping device which is usable to secure at least one end of a flexible plate to a cylinder utilizes a group of spring fingers that are shiftable radially in an axially extending slit in the cylinder to engage apertures in the end of the plate. The spring fingers have barbs that are receivable in these plate end apertures. The spring fingers are shiftable radially in the cylinder slit by rotation of a spindle situated in the cylinder.

Cylinder with plate clamping device

A supply and removal device for supplying printing plates to a plate cylinder utilizes a storage container which has adjacent compartments, one for the removal of printing plates and the other for the supply of printing plates. Each compartment has a mouth opening with the two such openings being located adjacent the surface of the plate cylinder in two adjacent quadrants.
