Patented Mar. 25, 1930 UNITED STATES PATENT OFFICE ALFRED A. GLIDDEN AND FRANK D. BEAN, OF WATERTOWN, MASSACHUSETTS, ASSIGN-- ORS, BY MESNE ASSIGNMENTS, TO HOOD RUBBER COMPANY, INC, OLE WATERTOWN, MASSACHUSETTS, A CORPORATION OF DELAWARE METHOD OF ORNAMENTING SHEET RUBBER Application filed October 26, 1928. Serial No. 315,306.

This invention relates to an improved method of ornamenting sheet rubber and to the article produced by said method.

The effect produced by the method hereinafter described is to give the sheet rubber the appearance of a fabric.

The invention consists in the improved method and article of manufacture hereinafter described in the specification and'particularly pointed out in the claims.

Referring to the drawings:

Figure 1 is a plan view of a piece of sheet rubber embodying our invention.

Fig. 2 is a section taken on line 2-2, Fig. 1;.

Like numerals refer to like'parts in the views of the drawings.

In the drawings, 5 is a sheet of rubber. 6. are projections thereon, and 7 are different groups of lines 8. It will be seen that the lines .8 of each individual group 7 are parallel to each other, but that the lines .in each group are positioned at angles to the lines of the difi'erentgroups adjacent thereto.

The article of manufacture of this invention is manufactured by passing sheet rubber between a pair of cold calender rolls, one of which is pebbled by covering the periphery of the roll with a large number of indentations and when the sheet rubber is passed between the calender rolls it is forced into the indentations and produces on one face of the rubber a large number of small projections. After thus embossing the rubber der is dusted off of the sheet, and the sheet isthen printed on the pebbled side with any design desired, by means of a printing ress, V

'nters ink gives satisfactory resu ts. The result,

either a platen press or a rota press.

as indicated in the drawing gives the sheet rubber the appearance of a fabric. .Any desired color 0 ink-may be used for the rintin and any desired design may be emp oyed.

o obtain variety in the appearance of the article manufactured by this method, the

ber which consists in sheet of rubber may be of a different color from the ink of the design printed thereon.-

It will be noted that while the lines of indentations 1n the calender, and therefore the pro ections 6 on the sheet of rubber, are arranged parallel to each other, yet the lines printed on the pebbled surface of the rubber give the appearance of the projections being arranged in groups,'the projections in one projections in other groups adjacent thereto.

We clann 1. The method ofornamenting sheet rubber which consists in passing sheet rubber between a pair of calender rolls, one of which is pebbled, then applying powder to the pebbled surface of the sheet, then removing the surplus powder, and subsequently printing a design comprising a plurality of groups of parallel lines, the-lines of each group being positioned at different angles to lines of the other groups.

2. As an article of'manufacture, sheet rubberhaving on one face thereof a plurality of projections and said face having a design printed in ink. thereon and consisting of a plurality of groups of lines, the lines of each group being parallel to each other and positioned at an angle to the lines of other groups.

3. The method of ornamenting sheet rubassing sheet rubber between a pair of calen er rolls, one of which is pebbled, and subsequently printing a design on the pebbled surface of said sheet, comprising a plurality of groups of parallel lines, the lines of each group being positioned at different angles to lines of the other groups.

In testimony whereof we have hereunto set our hands.
