This invention has -reference to an improved tape, strip or material adapted for use in temporarily securing together substantiallyv abutting edges of veneer whereby the application of said veneer to the usual backing or base is facilitated.
One object of the present invention is to provide a veneer tape, -stri or material of considerable strength to a ord the'desired` stability to the edges of the veneer to which said material is applied, 'and secured by adhesive, that said tape or material ultimately may be removed without abrasion and hence without danger of damage to the surface 0f the veneer.
A further vobject of the invention is to rovide a veneer tape, strip or material having adhesive that` after said tape or material has been aiiixed by its adhesive to veneer the removal of the tape or material from said adhesive maybe facilitated by treating the same to diminish the strength of the bond between said adhesive and the tape or backing material. A
Other objects of the invention will appear from the following description.
The invention consists in a veneer tape, strip or material comprising a backing of .comparatively strong paper or other fabricr and an adhesive united to said backing by a bond layer `of material inherently weakerv than said adhesive, in relation to its adhesion to paper, whereby through the moistening of said backing it may be drawn or stripped from said ad esive` without unduly softening said adhesive. The invention also contemplates the use of a bond layer between said backing and said adhesive which bond layer is of a nature that, under suitable treatment, it may facilitate the removal of the adhesive.
The invention also consists .in such other novel features of construction and combi- Specication of Letters Patent. 'Y

nation of parts as shall hereinafter be more fully described and pointed out in the claims. v
Figure 1, represents a plan view lof a piece of the improved veneer tape, strip or material portions of the adhesive and the bond layer being broken away.
Fig. 2, represents an edge view of the same. l A
Fig. 3, represents a Aperspective view showing the ta as uniting the edge portions of twp a jacent pieces of veneer, the backing being partially stripped from the 'bond layer.
Referring to the drawings in Vwhiclisiiiiilarl characters of reference designate corresponding parts throughout, 5 indicates a backing strip of comparatively strong paper or fabric, adapted when applied and aiiixed to two abutting pieces a, a of veneer to constitute a substantial union thereof. If said backingds of paper I prefer to utilize paper having little or no size or adapted from the comparative looseness of its fibrous structure readily to permit the passage of moisture through said backing or to facilitate the absorption of moisture by its fibers.
To one surface of this backing 5 I apply the bond or intermediate layer 6 which may Patented Nov. 18, 1919.V

rendered tacky or adhesive bythe application 0f heat.
The purpose of having the adhesive 7 of a waterproof or water resistin nature is to prevent the weakening Aof said adhesive by the action of moisture applied oi' absorbed by the material or tape backing 5.
p To this intermediate or. bond layer 6 I apply the coating or lm' lof waterproof or melting adhesive 7 of any vordinary nature preferably adapted to be hesivc 7 from the 'workby abrasion, said bond layer 6 may contain particles of grit or abrasive matter.
This improved tape or material' may be applied to veneer in the usual manner that is, for instance, the edges of the veneer a, a are brought together as shown in Fig. 3 of the drawings and the adhesive surface is placed against the surface of the veneer bridging the line of the edges of said veneer and heat is applied in any known manner to the backing 5 to soften the adhesive 7 and to render the same tacky and adherent to said veneer.
While I have obtained good results in removing the backing 5 by abrasion or stripping I have in mind as part of the present invention the treatment of bond layer 6 to weaken it or to diminish its tenacity. The preferred method of this treatment is through the application of moisture to the backingl 5 the porosity of which is such that the moisture readily penetratesthe same and acts on some of the material of bond layer 6 causin such material to soften and to swell su ciently to render it quite pul y without affecting the adhesive 7. After t ebond layer 6 has been thus treated the backing 5 and said layer 6 may readil be stripped from the adhesive 7 and said1 adhesive, in due course, may also be removed.-
In carrying this invention into practice fabrics and I have used to good advantage bond layers 6 of gum tragacanth and other gums and where it has been desirable to render said bond layer impervious I have used the starch with wax, emulsion, borax and china cla) As stated a ve the adhesive 7 may be of any known kind but preferably is of a' b waterproof or water resisting nature. In
this latter case I have found desirable an adhesivel made from suitable (proportions of refined asphalt, mineral oil an gutta perche, rubber, balata or other elastic material.
By the use of this improved veneer strip the removal of the pa r backing by the use of sand paper or ot er abrasive material or devices is unnecessary and damage to the veneer by such material or devices is avoided.
In the building up Qf a structure of su erposed veneers (joined together at their e ges y the adhesive 7 Aas above described) it is not always necessary or desirable to remove said adhesive. In some cases however the veneers secured together by the improved tape, are then secured to some kind of base, in the usual manner, with the surface of said veneers having said tapes outermost. In thisl case the backin 5 is first moistened and removed, as above escribed, and finally the adhesive'? is removed. If it is desired to remove said adhesive by abrasion the presence of the grit or abrasive material in the bond 6 or in proximity to the adhesive will facilitate the abrasion of said adhesive.
Having thus described my invention I Y backing of water absorbent material, a bond V layer normally adhering tosaid backing and f containing abrasive matter, and adhesive I have made use of backngs 5 of various HENRY J. MILLER.
