A TTORNE Y Patented May 19, 1931 UNITED STATES GUSTAVE ADOLPI-I NEW, PORT CLINTON, OHIO, ASSIGN'OR TO AMERICAN GYPSUM 00., OF PORT CLINTON, OHIO A CORI'QRATION O FOHIO REENFORCED Ann rnorncrnn WALL BOARD EDGE Application filed January 20, Serial No. 422,035.
margin is turned or folded into the core of the wet stucco 'mix. 1
In practice none of these methods has proved to be a complete success. A completely aper-covered edge has many objections or defects. In the manufacture of wallboard it is essential that the edge of the core should be firm and hard and substantially of the same structure as the center or otherv partsfof the core. The wet boards are dried in ovens or kilns and if the temperature varies the edges of the board are easily nipped or recalcined which means a soft and chalky edge. If such an edge is covered with paper, while the board may have a good appearance, the customer in reality pays for an inferior material, for a board which has a calcined or chalky core cannot be nailed properly to the studdings; all that. holds it is the paper through which the nails are driven.
On the other hand, if both margins are turned into the core, a partially open or raw edge is the result. The two margins sticking in the core cause a break in the solid structure in the edge of the core or board and instead of strengthening the same, they are weakened. Also when a nail is driven into such an edge, pieces of the set up core break loose due to the break in the structure caused by the dividing of the core from the two paper margins.
To have a solid, reenforced and strong edge, as well as a protective edge, which will stop suction between joints, I use the mesh cloth tape method as described in my patent application filed May 20th, 1929 Ser. No. 364,478 on which this is an improve ment.
In the accompanying drawings, Fig. 1 is j stucco. With this glue, a small percentage 2 is an enlarged verticalv section; T The stucco core or body is indicatedat -10. In the edge of'this is embedded astrip 'or tap'e'of fabric or webbing 8,theouter or projecting margin of which is foldeddown against and pressedpartly into the edge ;of thecore, as shown at 9. The top paper or cover is indicated atlland extends tothe edge of "the corejbeing cemented or otherwise fixed thereto in the usual manner. Under the core is a base or covering of rather porous or soft paper 12, which extends to the edge of the core, and covering this is bottom paper 6, preferably more dense or tough. The edge of this bottom covering 6, in --making the board, projects beyond the edge of the core. and is then folded up against the samefas shown at 7, covering the fabric margin 9 and the adjacent edge of the core, preferably'except a narrow bare strip 13 which is left open to permit water to evaporate therethrough while the board is going through the driers. It also leaves or forms a key for wet stucco mix which is I applied betweenjoints when the. boards are set up in use; The margin or lap 7 is glued to the edge of the board, preferably by animal glue which is a. retarding agent for of commercial retarder is preferably mixed, to prevent the suctiorfof fast setting between joints offreshly applied stucco, the retarder and glue preventing objectionable quick and weaksetting.
A board edge constructed as above described will be firm and hard and not sub" ject to splitting, cracking or break down by nailing, and will have other advantages apparent to those skilled in the art.
Iclaim: r
1. A plastic board comprisinga body having a textile fabric strip embedded inthe edge thereof, and paper coverings on oppo site sides of the body, one of said coverings having a marginal flap folded against said edge and across said strip.
2. A plastic board comprising a body having a textile fabric strip embedded inthe edge thereof, and paper coverings on oppoa'perspectiveof a portion ofthe board. Fig.
site sides of the body, one of said coverings having a marginal flap folded against sald edge and across said strip, the strip having a portion thereof folded against the said edge, under said flap.
3. A plastic board comprising a body having a textile fabric strip embedded in the edge thereof, and paper coverings on opposite sides of the body, one of said coverings having a marginal flap folded against said edge and across said strip, said flap being narrower than said edge is thick, whereby an exposed strip of the body is left uncovered.
4. A plastic board comprising a body having a textile fabric strip embedded in the edge thereof, and paper coverings on opposite sides of the body, one of said'coverings having a marginal flap folded against said edge and across said strip, said flap being attached to said edge by glue having a retarder mixed therewith.
In testimony whereof, I do affix my signature. p
