End seal with insert for chambered doctor blade assembly
Abstract:
An end seal for removable attachment to a doctor blade assembly is provided. The end seal comprises a seal body having a bottom wall, opposite first and second sidewalls and a top edge configured to include a radius adapted to seal against a roller surface. At least one abrasion resistant insert is integrally secured within the seal body. The insert includes a bottom wall, opposite first and second sidewalls and a top edge configured to coincide with the body top edge so as to seal against the roller surface. The abrasion resistant insert may further include one or more holes wherein the seal body impregnates the holes. One or both of the opposite first and second insert sidewalls and/or the insert bottom wall may reside within and be encapsulated by the seal body. The abrasion resistant insert may be constructed of polytetrafluoroethylene, a perfluoroalkoxy alkane or fluorinated ethylene propylene.
