Abstract

Abstract A method of securing metallic tubing and the like to a flat metal sheet while maintaining the flatness of the sheet so that the composite tube and sheet may be used as radiant heating or cooling panels in building interiors where distortion or wrinkling of the flat sheet would be undesirable. The apparatus comprises a heating station where a composite of sheet, of suitably disposed bonding material, and a piece of tubing in properly assembled relationship and under pressure are heated to induce a bond between the tubing and the sheet while maintaining the sheet in flat condition. An assembly station is provided including a jig in which the piece of tubing may be accurately located, means for accurately locating the jig with respect to the sheet, and means for raising and lowering the jig and for releasing the jig from the raising and lowering means so that it may move with the assembly from the assembly stations to the heating station. After the heating cycle, the assembly moves to a cooling station (which may be the same as the assembly station) for a cooling cycle. A combined assembly and cooling station may be provided on each side of the heating station, each assembly station having a jig whereby production may be speeded up.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 159 words
A jig for use in joining metallic tubing to a flat sheet of metal, comprising a flat plate of a metal which will remain substantially undistorted at joining temperatures, and having a length and width at least substantially equal to those of said sheet of metal, a block of non-metallic material having good mechanical strength at said joining temperatures, and having relatively poor heat conductivity and having at least the same length and width as said plate and secured to the underside of said plate, said block having on its underside a recess configured to accommodate said tubing and of a depth greater than the diameter of said tubing, and resilient means secured in said recess, said resilient means being of a material which will maintain its resilience at said joining temperatures, said resilient means exerting pressure against said tubing when said tubing is within said recess and tangent to the plane of the bottom surface of said jig.
Claim 2
Dependent Claim 159 words
A jig for use in joining metallic tubing to a flat sheet of metal, comprising a flat plate of a metal which will remain substantially undistorted at joining temperatures, and having a length and width at least substantially equal to those of said sheet of metal, a block of non-metallic material having good mechanical strength at said joining temperatures, and having relatively poor heat conductivity and having at least the same length and width as said plate and secured to the underside of said plate, said block having on its underside a recess configured to accommodate said tubing and of a depth greater than the diameter of said tubing, and resilient means secured in said recess, said resilient means being of a material which will maintain its resilience at said joining temperatures, said resilient means exerting pressure against said tubing when said tubing is within said recess and tangent to the plane of the bottom surface of said jig.
Claim 3
Dependent Claim 48 words
A jig according to claim 1, wherein locating means are provided to insure proper positioning of said tubing in said recess, and releasable means are provided for retaining said tubing in said recess during positioning on a sheet of metal to which said tubing is to be joined.
Claim 4
Dependent Claim 60 words
A jig according to claim 2, wherein said recess is of sinuous configuration for use with tubing of congruent sinuous configuration, and wherein said locating means are in the form of pins entering said recess at convex regions of said sinuous recess, and provided with means to urge them into contact with a piece of tubing disposed in saId recess.
Claim 5
Dependent Claim 52 words
A jig according to claim 1, in combination with means for raising it for insertion of a piece of tubing, and lowering it for positioning the piece of tubing on a sheet to which the tubing is to be secured, and means for releasing said jig from said raising and lowering means.
