Abstract
Members, such as paper machine forming board drainage foils, and the like, are adapted to be mounted in a predetermined substantially accurate attitude unaffected by possible irregularities on a metallic supporting structure, by providing the supporting structure with fixedly secured non-warping nonmetallic base means which is machined substantially accurately to receive and mount the members.
Claims18
A method of precision mounting for members on an elongate metallic supporting structure, comprising:
- forming said metallic supporting structure in a manner avoiding excessive warpage;
- preparing a facing area along substantially the full length of said supporting structure for receiving mounting base means on said area;
- applying and fixedly securing to said area mounting base means comprising easily machinable nonmetallic material which is substantially free from tendency to warp during machining and extending in the form of a continuous strip covering said area;
- and after said applying and securing of said base means substantially accurately machining an exposed receiving surface on said base means for receiving and mounting said members on said receiving surface in a predetermined substantially accurate attitude unaffected by irregularities that may be present in said area and which irregularities might otherwise make it difficult to attain said substantially accurate attitude of said members in the absence of said machined nonmetallic base means.

An elongate metallic supporting structure having means for precision mounting of members thereon, comprising:
- said metallic supporting structure being formed to avoid excessive warpage and having a facing area along substantially the full length of said supporting structure prepared for receiving nonmetallic mounting base means;
- easily machinable nonmetallic mounting base means applied to and extending in the form of a continuous strip covering said area, said mounting base means comprising a material which is substantially free from tendency to warp during machining;
- means securing said mounting base means fixedly onto said area;
- and said mounting base means having an exposed receiving surface substantially accurately machined after securing of said mounting base means onto said area, for facilitating receiving and mounting of said members on said surface in predetermined substantially accurate attitude unaffected by irregularities that may be present in said area, and which irregularities might otherwise make it difficult to attain said substantially accurate attitude of said members in the absence of said machined nonmetallic base means.
