Apparatus for, and method of, mounting a printing plate on a cylinder of a printing press

An arrangement for securing a (possible undersized) flexible printing plate to a printing cylinder comprises the provision on the cylinder of leading and trailing edge clamps which between them secure and tension a full sized cover sheet on the cylinder, one edge clamp being adapted to releasably receive an edge of the plate without consequential release of the underlying cover sheet. As described, the cover sheet is non-releasably secured to the leading edge clamp assembly (as by screws) and clamped by the trailing edge clamp, thereby leaving the clamp of the leading edge clamp assembly free for accepting the plate. The invention is adapted for the securement of undersized non-metallic (e.g. polyester) plates. ...

Universal under-packing for rubber-coated fabrics on offset printing press cylinders

Sheets of rubber-coated fabric are mounted on the cylinders of offset printing presses. An under-packing formed from the combination of a flexible supporting sheet (12), which may however be dispensed with, and a multiplicity of flexible graded sheets (14) has to be interposed between the cylinder surface and the rubber-coated fabric to obtain a predetermined total thickness which varies as the type of printing press varies. The total thickness of the universal under-packing (10) according to the invention is equal to a predetermined maximum thickness. The thickness of the sheets (12, 14) of the universal under-packing (10) is chosen such that by removing from the universal under-packing (10) one or more graded sheets (14), the thickness which has to be obtained for any specific case can be sufficiently approximated to.

FLEXIBLE JACKET COATING AND ITS MOUNTING METHOD

PROBLEM TO BE SOLVED: To provide an improved type method and apparatus for transferring a freshly printed sheet S supported by a movable ink repellent and electric conductive jacket cover 58 made of a flexible material which is fitted to a transfer cylinder 10. SOLUTION: Occurrence of a static electric charge on a transferable flexible jacket covering is prevented by containing an electric conductive material in the jacket covering material or processing by a charging preventive ion polymer compound which makes the jacket covering electric conductive. Since a static electric charge sent to the flexible jacket covering by friction contact to the freshly printed sheet is attracted to the transfer cylinder via an electric conductive cylinder base part covering which is low in a static friction coefficient to the jacket covering, occurrence or accumulation of a static electric charge does not occur on the flexible jacket covering.

A mandrel for printing apparatus, a printing cylinder and printing apparatus

A mandrel for use in a printing apparatus. The mandrel comprises a substantially cylindrical mandrel shaft and plastic expansion rings that are slidably and coaxially mounted on the mandrel shaft. The mandrel also includes a locking assembly including a fixed stop ring and a single locking ring that is axially movably mounted on the mandrel shaft. The expansion rings are positioned between the stop ring and the locking ring. In the unlocked position of the locking ring the expansion rings are in a released state in which the axial compression and the radial expansion of the expansion rings are smaller than in a locked position of the locking ring. A printing cylinder sleeve can be fixedly connected to the mandrel by bringing the expansion rings in the radially expanded state. When the printing cylinder sleeve has to be exchanged, this is feasible when the expansion rings are in the released state.

Anti-static, anti-smearing, pre-stretched and pressed flat, precision-cut striped flexible coverings for transfer cylinders

Freshly printed sheets are transferred from one printing unit to another by transfer cylinders each having an ink repellent, electrically conductive, striped flexible jacket covering that is movable relative to the sheet support surface of the transfer cylinder. The jacket covering is made of a flexible fabric material that is pre-stretched, pressed flat, cut to size and treated with an ink repellent compound and is also treated with an anti-static ionic compound or is otherwise rendered electrically conductive by one or more conductive strands. Electrostatic charges carried by the freshly printed sheets are discharged through the ink repellent, electrically conductive, flexible jacket covering into the grounded transfer cylinder. A low friction, electrically conductive cylinder base covering that includes center alignment marks is secured to the transfer cylinder for engaging the flexible jacket covering. The ink repellent, electrically conductive flexible jacket covering is provided with alignment center marks and alignment stripes so that the flexible jacket covering can be precisely aligned with ease and secured over the gripper edge, tail edge and side edges of the transfer cylinder. The low frictional coefficient of the conductive cylinder base covering is further reduced by nodes and/or openings.
