CONTRIVANCE FOR COVERING CARDBOARD, SHEET METAL, WOD, &c.,

WITH PAPER, &c.

Specification of Letters Patent.

Patented Feb. 27, 1906.

Application filed June 29, 1905. Serial No. 267,496.

To all whom it may concern:

Be it known that I, FERDINAND EMIL J AG- ENBERG, a subject of the German Emperor, residing at Dusseldorf, Germany, have invented a new and useful Contrivance for Govering Cardboard, Sheet Metal, Wood, &c., with Paper, Woven Materials, &c., of which the following is a full and complete specification.

My invention is thereby characterized that it effects the covering not only rapidly,but in 'such a manner that no creases are allowed to form and that comparatively little adhesive substance is used. Till now the covering has been effected by giving the material forming thecovering a coat of the adhesive substance either by hand or mechanically when it was pressed onto the object to be covered, or vice versa. This method has several disadvantages. As the actual covering does not take place immediately after the application of the adhesive substance, the latter has time to saturate the paper, rendering in most cases the tight and creaseless drawing of the material impossible. It also often happens that the adheringparts get askew, thus necessitating their being strai htened out later, so that to make this possi lo the adhesive substance must be put on thickly. In addition to this comes the important consideration that the operators hands being soiled by contact with the glue, &c., often greatly detracts from the appearance of the cover. Besides this, the work of covering by hand is laborious and occupies a great deal of time and can be done only by skilled labor.

The new contrivance is thereby characterized that the paper, fabric, &c., for the most part is thoroughly supplied with the'adhesive substance before it leaves the glue-roller and is simultaneously brought into contact with the board or other object to be covered by being pressed between two rollers which are placed as near as possible to the roller bearing the adhesive substance. These pressingrollers revolve at such a speed that the material coming from the glue-roller is held taut and pressed onto the object without creases. The invention is shown in the drawing, which represents a longitudinal section of my improved cardboard-covering machine.

The coverin material a is fed by rollers 12 to the gluero ler c and travels thence beneath guides d, which take it to the guideroller e in such a manner that the glued side is outward. The rollers b and e are arranged in proximity to glue-roller 0, but are placed at a distance from each other, so that the covering material a is held in contact with the surface of roller 0 between the rollers b and 0. Over the roller e there is the pressure-roller f, influenced b the spring h. In front and behind the rol ers e and f there are the feeding and taking-off tables 9. When the end of the paper, &c., arrives between the rollers e and f, the cardboard 'i is also introduced, and the covering material a is then put on the object absolutely without creases. If desired, there may be more than one roller Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, i.s

In a cardboard-covering machine, a glueroller, combined with a feed -roller and a guide-roller placed in proximity to the glueroller at a distance from the feed-roller, a pressure-roller above the guide-roller, and a divided feedtable at opposite sides of the guide-roller, substantially as specified.

Signed by me at Dusseldorf, Germany, this 8th day of June, 1905.
