Abstract
A printing press ink scraping blade is disclosed. The ink scraping blade is of a unitary construction and includes a working end as well as a mounting end. The working end is preferably substantially thicker than the mounting end to provide substantially more material at the working end. As the scraping blade engages a scraping roller of a printing press, the blade is exposed to abrasive action and the additional material provided increases the serviceable life of the blade. To ensure that the blade maintains sufficient flexibility and deflection characteristics, the remainder or mounting end of the blade, is of a substantially reduced thickness. The blade may be manufactured from spring steel to further enhance flexibility.
