PADDINQ FOR ROLLS Filed July 22, 1925 INVENTOR Y /;/W J//L B J i; ATTORNEY Patented Sept. 3, 1929.

UNITED STATES JOHANNES H. UHLIG, OF DETROIT, MICHIGAN.

IPADDING FOR ROLLS.

Application filed July 22, 1925.

The present invention relates to padding materials for rolls and particularly for the rolls of ironing machines.

Heretofore, on rolls of various machines where padding is required, various forms 01 padding material have been used with varying success, but always when a strip is wrapped around the roll, there is difliculty in avoiding a seam or hump where the ends of the material come together or lap over.

The present invention has for its object the overcoming of this objection by providing a padding material that will form a lap having the same thickness as the rest of the material.

- cotton running lengthwise and tied together with a web of thread. These rovings are usually quite large and form a padding sheet of about a quarter of an lnch thick. Lapping the ends of this makes quite an appreciable bump.

In the present instance this objection is overcome by removing a portion of the material from the ends of the pad so that the lapping portion on each end gradually decreases in thickness, the two ends lapped forming together about the thickness of the body portion of the material.

In the specific embodiment shown, this is done by cutting notches in the ends of the material so that about half of the material is removed for a short distance back from the end. The remaining material will then mash down so as to taper off in thickness from the bottom to the top of the notches and the lapping edges will lie as shown in Fig. 2.

In the drawing, the body of the padding material is indicated at 5 having the rovings at 6 and the web threads at 7 well spaced. The notches are indicated at 8 with the lapping ends indicated, in Fig. 2, at 10 and 11 on the roll 12.

Serial No. 45,198.

While, in the above description, cotton rovings have been mentioned as the material used. the invention is also applicable to other padding textiles and woolen or even other woven padding may be prepared in the same manner with good results.

Having now described the invention and the preferred form of embodiment thereof, it should be understood that it is not to be limited to the precise details described and illustrated but only by the scope of the claims which follow.

Claims:

1. A padding material for rolls consisting of a sheet of'woven textile padding material of surhcient length to encircle the roll one or more times and lap a short distance, the sheet having some of the warp material removed from its ends so as to decrease the thickness thereof.

2. A padding material for rolls consisting of a sheet of textile padding material of sufficient length to encircle the roll one or more times and lap a short distance, the sheet having notched ends.

3. A padding material for rolls consisting of a sheet of cotton rovings of sufiicient length to encircle the roll one or more times and lap a short distance and having the rovin gs held by a wett of threads, the sheet having some of the material of the rovings removed trom its ends so as to decrease the thickness thereof.

4. A padding material for rolls consisting of a sheet of cotton rovings of suiiicient length to encircle the roll one or more times and lap a short distance, the sheet having sufficient material of the rovings removed from the ends so that the lapped portions are together of substantially the thickness of the sheet.

5. A padding material for rolls consisting of a sheet of cotton rovings of sutlicient length to encircle the roll one or more times and lap a short distance, the sheet tapering in thickness for a distance equal to the width of the lap.

6. A padding material for rolls consisting of a sheet of cotton rovings of suliicient length to encircle the roll one or more times and lap a short distance, the sheet having notches cut into its ends to a depth substantially equal to the width of the lap.
