The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method and process to produce and attach air spacers, compromising:
a. an adhesive composition mixture usually made up of ground wood and resin binders, such as formaldehyde based resins or methlylene diphenyl di-isocyanate, plus possibly other materials, is produced; and
b. a moving process line of a protective layer panels, such as oriented strand board (OSB), synthetic style underlayment or metal panels; and
c. die or spray heads apply the adhesive composition mixture to the panels or synthetic style underlayment in parallel mixture lines, or forming air spacers, approximately 1\xbc to 1\u215cths inches apart, 116 to \u215bth inches wide and \u215dths to 1 inch high; and
d. the adhesiveness of the adhesive composition mixture allows the adhesive composition mixture to adhere to the panels or synthetic style underlayment; and
e. forming guides may be used help form the mixture into the desired designed shape, and
f. radiant reflective materialfilm may be adhered to the top edges of the mixture line usually by the remaining adhesiveness of the mixture line; and
g. when the composition adhesive mixture hardens to the desired stiffness the panel’s air spacers and radiant reflective materialfilm is cut at the edges of the panels, separating the panels, or the synthetic style underlayment radiant reflective and venting assembly is cut to the desired length.
2. A method and process to produce and attach air spacers according to claim 1, where the adhesive composition mixture is developed and applied under pressure andor heat created by grinding such as by a conical co-rotating grinder or extruder.
3. A method and process to produce and attach air spacers according to claim 1, where heat is added to the adhesive composition mixture before being applied by the die or spray heads.
4. A method and process to produce and attach air spacers, according to claim 1, where a release agent may be applied to sections of the forming guide to help release the adhesive composition mixture from the forming guides.
5. A method and process to produce and attach air spacers, according to claim 1, where the protective layer are panels such as oriented strand board (OSB) or plywood; and
a. the panels move individually down the process line edge to edge lengthwise, and b. the form guide’s height tapers down to allow the radiant reflective materialfilm to touch and adhere to the line mixture; and
c. a non-collapse guide may be used that lies between, and does not touch, the mixture line to keep the weight of the adhered radiant reflective materialfilm from collapsing the height of the mixture line and to keep the surface top edge width mixture line connection point to the radiant reflective film surface to the desired minimum; and
d. when the mixture line hardens to the desired point a cutting device cuts perpendicular to the mixture line along with the radiant reflective material, at the edge of the finished panel.
6. A method and process to produce and attach air spacers, according to claim 1, where a synthetic underlayment style material is rolled out in a process line; and
a. the composition mixture is placed into mixture line forming guides which are placed perpendicular to the rolled out length on the synthetic underlayment material, and
b. the line mixture is filled into the forming guides, which are closed off at each end to not let the line mixture flow out each end of the guide; and
c. the forming guides may not run the full width of the underlayment material but rather may leave a small longitudinal end section or overlap tab, free of the formed mixture line, and
d. the line mixture forming guides move along parallel to each other parallel to each other and laterally down the process line at the same speed as the synthetic underlayment, and
e. the forming guides are designed and shaped to allow a certain amount of line mixture to cover and be formed on most of the entire surface (surface mixture) of the synthetic underlayment; and
f. the surface mixture is usually thicker nearest the mixture lines and usually tappers to a thinner at a point between the two mixture lines; and
g. when the linesurface mixture hardens to the desired rate the forming guides are lifted up vertically and then are moved in a circular motion back to the point on the process line and placed on the synthetic underlayment at the original point that they were first filled with the linesurface mixture and the repeated process of the forming guides moving down laterally with the filled line mixture is continually performed; and
h. once the linesurface mixture is free of the forming guides, radiant reflective material, usually unrolled reflective film, is placed upon the top edges of the line mixture and is adhered to the line mixture usually by the remaining adhesiveness of the line mixture; and
i. as the linesurface mixture hardens further at a certain point on the process line the protective layer, now composed of the synthetic underlayment and the added surface mixture, the mixture line and the reflective materialfilm is cut leaving the radiant reflective and venting assembly a desired length; and
j. the assembly is then rolled up with the now somewhat rigid protective layer being on the outside of the roll with the tapered surface mixtures center points between each mixture line being flexible enough to allow the protective layer to bend at these surface mixture center points.
