Abstract

This disclosure is directed to an improved fluid-applicatingwick for use in applying release fluids to a fuser member surface of a fusing system for fusing toner images in an electrostatic copying device, The wick comprises a working surface material which contacts the fuser member surface and a backing material to which the working surface material is needled. A preferred fluid-applicatingwick comprises a layer of Teflon felt or fiber as a working surface material needled to a fibrous or felted Nomex material.

WICK FOR DISPENSING FUSER OIL Proposed Classification 3oseph A. Swift U.S. Cl. 118/266

mt. Cl, B05c 11/00

This disclosure is directed to an improved fluid~applicatingwick for use in applying release fluids to a fuser member surface of a fusing system for fusing toner images in an electrostatic copying device, The wick comprises a working surface material which contacts the fuser member surface and a backing material to which the working surface material is needled. A preferred fluid~applicatingwick comprises a layer of Teflon felt or fiber as a working surface material needled to a fibrous or felted Nomex material.

In accordance with the present disclosure, the wick material has two or more layers, at least some of the material of at least one of the layers extending into the material of at least one of the layers. Composite wick material made in this manner results in substantially higher release fluid throughput and uniform spreading of the release fluid on the fuser member without sacrifice of the functional or useful life of the composite wick material. The needling, i.e., extending some of the material of at least one of the layers into the material of the other layer, is described in U.S. Patents 2,840,831 and 3,090,099.

Referring to the drawing, there is shown a fragmented view of a portion of a preferred composite wicking material having the characteristics of the present disclosure. The composite wick comprises a first material o...
