Definitions

  • This invention generally relates to an apparatus for use in spray etching systems and, more particularly, to apparatus for forming sealing engagement along the edges of a continuously moving web and thereby isolate one side of the web from the opposite side of the web while etchant is being applied to one of the sides of the web.
  • the present invention has its greatest utility where one side of an article is to be etched followed by a later step of simultaneously etching the article on both sides.
  • a shadow mask or aperture mask is located between the electron guns at the rear of the tube and the phosphor coated faceplate to the face of the tube.
  • An electron beam passes through the tiny openings or apertures in the shadow mask and impinge upon a suitable color producing phosphor dot on the faceplate.
  • Located along with openings on the shadow mask are three phosphor dots, a triad, one dot for each of the three primary colors.
  • the shadow mask openings are used as a guide for the electron beams.
  • one of the-uses of the present invention is for an apparatus for manufacturing of the shadow mask for use in the television tubes.
  • one of the problems overcome by the present invention is the difficulty in obtaining a seal around a moving web.
  • this problem is compounded by the fact that the web has a layer of resist on both sides which must not be flaked or peeled off by the sealing apparatus.
  • the present invention comprises an apparatus for sealing around the edges of a continuously moving resist covered web without stripping the resist from the web.
  • the apparatus comprises a pair of edge support guides and a pair of elongated air inflated bags that provide a constant force to hold a pair of pliable sealing members in a sandwich sealing arrangement along the edges of the web.
  • FIG. I is a cross section elevation view of the web sealing apparatus.
  • FIG. 2 is a schematic view of an etching system employedin the apparatus of the present invention.
  • etchant spray nozzles 22, 23 and 24 etchant spray nozzles 22, 23 and 24. Consequently, it is desired to prevent any etchant from spraying or leaking around to the top side of web 9. If etchant spray or fumes should come in contact with the opposite side of the web, one would produce pre-etching which would make it impossible to accurately etch out the openings of the final etching step. Accordingly, to prevent the leakage of etchant fluid or etchant fumes around the edges, there are provided a pair of support guides 14 and 15 which the edges of the web 9 rest on. Other suitable rollers (not shown) support the center of web 11.
  • Sealing members 16 and 17 are relatively thin flexible sections to enable the force from the air bags to be uniformly transmitted to the edges of the web. Any number of materials are suitable, however, self-lubricating sealing members of polytetrafluoroethylene are preferred because of wear resistance and ability to withstand attack from the etchant fluid.
  • an inflatable air bag 18 which is held in place by a curved mounting fixture 19 which is mounted on the side of the etching chamber.
  • an inflatable air bag 20 located on the opposite side of the etching chamber and on top of guide 17 is an inflatable air bag 20 which is held in place by a curved mounting fixture 21.
  • reference numeral 30' designates an etching system for use with thepresent invention.
  • Etching system 30 contains a first set of etching chambers' 31, 32 and 33 and a second setof etching chamb'ers 3.4, 35, 36'and 37.
  • Etching chambers 31, 32, 33, 34'and 35 respectively contain a s'etof etching nozzles 50, 51,52,53 and 54 which are located beneath the article to be etched.
  • etching chambers 36 and 37 and-nozzles 55 and 56 are located above the web 9 and spray etchant from above the web while the lower nozzles 53 and 54 spray from beneath the article.
  • the sealing apparatus shown in FIG. 1 is locatedin etcl'iing' stations 31', 32 and 33 'to prevent the etchant spray from nozzles 50, 51 and 52 from passing around the web and onto the top of the web as it passes through the successive etching stations.
  • a squeegee or wiping member for wiping clean the resist layer before it enters etching chambers 36 and 37.
  • the squeegee removes any liquid or water or othermaterial which may been the web before entering etching chambers 31, 32 and 33.
  • the wiping unit comprises a large diameter roller 40, a support member 43 ,which is mounted to the chamber and a pair of squeegees ,4l and 45 which are held in pressure contact with web 9 by a pair of,springs 42 and 46. These squeegees wipe off and clean the top of the resistlayer so that the top side of the web is ready for the final etchinginetching chambers 36 and 37.
  • the bottom side of the inflatable bag could be made of a thicker wear resistant material and this elimi nates the need for separate flexible sealing members.
  • an etching chamber for directing etchant at one face of a web
  • said flexible sealing means located in said etching chamber for supporting the opposite edges of said web including a firstpair of sealing members for contacting the edges on one I face of said web; and flexible sealing means for coacting with said first pair of sealing members for sealing the edges of said web between said first pair of sealing members and said flexible sealing means to thereby provide a barrier to etchant leaking past the edges of the web.
  • said flexible sealing means includes a second pair of flexible sealing members for contacting the edges located on the opposite face of said web.
