strip and process of making the same, said strip being adapted to be folded along a straight line lengthwise of the strip. Such stay strips are generally used to stay the corners of boxes and their construction is such in a manner as to adapt them to be readily folded longitudinally at the corner of the box and attached to the two adjoining sides of the box in the manner well known to those skilled in the art.
Various kinds of gummed strips have been hitherto made but so far as known to me they have been found in practice to be more or less objectionable for various reasons.
The object of my invention is to provide a gummed stay strip which will fold readily, neatly and accurately along a line lengthwise of the strip, which will not be weakened at the folding line, and which will adhere smoothly and evenly throughout its entire surface to the adjoining sides of the box or other object to which it may be applied.
The nature of the invention is fully set forth in the following description taken in connection with the accompanying drawings, and the novel features thereof are particularly pointed out and clearly defined in the claim at the close of this specification.
In the drawings, Figure l is a perspective on an enlarged scale of a piece of gummed stay strip embodying my invention. Fig. 2 is an end view of the strip shown in Fig. 1, also enlarged to more clearly show the construction.
Referring to the drawings A represents a piece of gummed stay strip embodying my invention. In practice these gummed strips are made of various widths and lengths and are usually for convenience inshipment and use coiled into rolls or coils containing a given number of yards. This strip A com prises a body 2 which may be of cloth, paper Specification of Letters Patent.

or other suitable material. I form in this strip along the line lengthwise thereof at which the strip is intended to be folded a depression 3 which in cross section is rounded as shown. The depth of this depression is preferably about one-half of the thickness of the material of the strip. The depression 3 is not formed by cutting or otherwise impairing the material of the strip 2 but is formed by calendering process, that is by passing the strip between a roll having a fiat periphery and a narrow or th n roll with a rounded edge corresponding in shape with the shape of the depression 3. The effect is-to calender and densify the paper at this point and form a depression. This depression may obviously vary'considerably in width. After being thus treated the strip has a depression lengthwise on one surface and is smooth on the other surface. After this calendering operation the strip is coated with a layer of adhesive 4 in the well known manner. The adhesive fills the depression 3 and presents when dry a smooth surface so that the finished strip is smooth on both surfaces, that is has no de pression or projection on either face thereof. If a more or less transparent adhesive be used, as is generally the case, the greater depth or thickness of adhesive in the depression 3 will serve to slightly darken the surface of the material over the depression 3 and will thus make it possible to detect visually the position of the depression. A strip of this kind having in the body or backing thereof a depression formed as above set forth by calendering and having the depression entirely filled by adhesive will fold neatly and accurately along the line of the depression, will be very strong, at the folding line, in fact stronger than at other points due to the increased quantity of adhesive which fills the depression, while the strength of the strip at and beneath the depression is fully preserved, and will adhere very easily and uniformly to the surfaces to which it may be applied.
What I claim is;
As an article of manufacture, a gumined stay strip comprising a body of sheet material having in one face a longitudinal groove. the opposite face being level throughout, the portion of said body between the base of the groove and the oppo- Q I f 7 1,149,344
