Specification of Letters Patent.
Patented July 12, 1921.
Application filed July 6, 1920. Serial No. 394,093.
To all whom it may concern:
Be it known that we, CONRAD M. CommosoX and PRENTICE (oxnaosom citizens of the l'nited States, residing at Madison, in the county of Dane and State of Visconsin, have invented certain new and useful Improvements in Paper Towels, of which the following is a specification.
The object of our invention is to provide a paper towel having a multiplicity of rough, broken edges which will rapidly absorb the moisture when the towel is rubbed over the hands or on the face.
The invention consists in a paper towel, as hereinafter described and particularly pointed out in the claims.
In the accompanying drawings forming part of thi specification,
Figure 1 is a view of a paper towel embodying our invention,
Fig. 2 is an enlarged detail view of a portion of the towel,
Fig. 3 is an enlarged section.
In the drawing, 2 represents a paper towel provided with a series of elongated perfora tions 3. These perforations are preferably made in the paper without removing any of the material, leaving ragged fibrous edges which will more readily absorb moisture than the machine-finished surface of the paper. The perforations may be made by dies or rolls, the material being pressed outwardly beyond the plane of the paper sheet and preferably the projecting edges of the perforations alternate on opposite sides of the paper. The perforations may be of any suitable shape, elongated, circular or oval, and they may be made as a step in the papertowel making operation or they may be made by a separate process.
'lhe perforations may be arranged to cover the entire surface of the sheet or made in any design or pattern, or the edge of the sheet may be left unperforated or with one or more strengthening bars of the paper across 1t.
As shown in Fig. 3, the perforations provide a series of rough edges 4 which, when the towel is rubbed over the hands or on the face, will contact with the wet surface and rapidly'absorb the moisture. In this way a paper towel may be much more eflicient than where the paper presents an unbroken finished surface.
lVe claim as our invention:
1. As a. new article of manufacture, a paper towel having a plurality of openings therein, the edges of said openings being rough and exposed for absorbing the moisture contacting therewith.
2. As a new article of manufacture, a paper towel having a plurality of perforations therein, the edges of said perforations being rough and pressed outwardly beyond the plane of the towel to absorb the moisture contacting therewith.
3. As a new article of manufacture, a paper towel having a series of perforations therein, the edges of said perforations being pressed outwardly upon opposite sides of the towel and adapted to rapidly absorb moisture on the hands and face.
4. As a new article of manufacture, a paper towel having a series of elongated slits formed therein in staggered relation, with the edges of said slits pressed outwardly beyond the plane of the towel, said edges being raw and broken for edgewise contact with the skin and the absorption of the moisture thereon.
In witness whereof, we have hereunto set our hands this 30th da of June, 1920.
