US Patent:

Filed:

Jul 15, 1996

Appl. No.:

08/683600

Inventors:

Howard Curtis Secor - Coppell TX
Ronald Merod Rendleman - Dallas TX
Paul Drake Copenhaver - Colleyville TX

Assignee:

Printing Research, Inc. - Dallas TX

International Classification:

B41F 3500

US Classification:

1014241, 101488

Abstract:

An infra-red dryer utilizes high velocity air jets which scrub and break up the moist air layer which clings to the surface of a freshly printed and/or coated sheet. The high velocity air jets are directed through multiple air flow apertures across an array of infra-red lamps onto the freshly printed and/or coated sheets. An extractor exhausts the moisture-laden air from an exposure zone while short wave infra-red radiation heats the ink and/or protective coating. The effective exposure to pressurized air is increased by the air jets which produce a balanced pressure air blanket along the sheet travel path. The moist air layer is displaced from the printed and/or coated sheet and is extracted from the press as the sheet moves through the exposure zone.

International Classification:

B41F 516

US Classification:

101177, 101185, 10135201

Abstract:

A retractable in-line inking/coating apparatus selectively applies either spot or overall ink/coating to a blanket or flexographic plate on a blanket cylinder or spot coating or overall ink/coating to a flexographic printing plate on a plate cylinder in a rotary offset printing press. The inking/coating apparatus is pivotally mounted on the tower of a printing unit or dedicated coating unit, and is extended into and retracted out of inking/coating engagement by a carriage assembly which is pivotally coupled to the printing unit tower. Because of the pivotal support provided by a cantilevered support arm, the inking/coating apparatus can be raised and lowered through a Ferris wheel arc movement between adjacent printing units. The aqueous component of the printing ink or coating is evaporated by a high velocity, hot air interstation dryer and a high performance heat and moisture extractor so that the ink on a freshly printed sheet is dry before the sheet is printed on the next printing unit. Thus, flexographic ink or coating applied at the first printing unit can immediately be overprinted on subsequent printing units.

International Classification:

B41F 22/00
B25B 27/14

US Classification:

1014161, 29270

Abstract:

In a printing press having a transfer cylinder for transferring a freshly printed substrate, a method of preparing the printing press for printing. The method comprises placing a first edge of an assembly of flexible jackets over a hook type attachment structure coupled to a first edge of the transfer cylinder and pressing the assembly of flexible jackets into contact with the hook type attachment structure, wherein the pressing is performed by rolling surface contact between the assembly of flexible jackets and an attachment tool comprising a handle and a cylinder coupled to the handle, wherein the outer surface of the cylinder is irregular in texture.

International Classification:

US Classification:

101177

Abstract:

A retractable in-line inking/coating apparatus can apply either spot or overall inking/coating material to a plate and/or a blanket on the first printing unit or on any consecutive printing unit of any rotary offset printing press. The inking/coating apparatus is pivotally mounted within the conventional dampener space of any lithographic printing unit. The aqueous component of the flexographic printing ink or aqueous coating material is evaporated and dried by high velocity, hot air dryers and high performance heat and moisture extractors so that the aqueous or flexographic ink or coating material on a freshly printed or coated sheet is dry and can be dry-trapped on the next printing unit. The inking/coating apparatus includes dual cradles that support first and second applicator rollers so that the inking/coating apparatus can apply a double bump of aqueous/flexographic or UV-curable printing ink or coating material to a plate on the plate cylinder, while simultaneously applying aqueous, flexographic or UV-curable printing ink or coating material to a plate or a blanket on the blanket cylinder, and thereafter onto a sheet as the sheet is transferred through the nip between the blanket cylinder and the impression cylinder. A triple bump is printed or coated on the last printing unit with the aid of an impression cylinder inking/coating unit.
