Application filed March 27, 19l8. serial No. 2253093.

To all whom it may concern e a Belt known that I, Gnonens Gasoline, of 3 Rue Saulmer, Paris, France, manufacturer, have invented Machines for Waxing Sheets ofCigarette-Paiaer, of which the following is a full, clear, and exact description.

The various types of machines heretofore known for waxing sheets of cigarette paper have only a very small output and do not always assurework which is entirely satisfactory especially in the event of the paper being of inferior quality or imperfectly calendered,

The subject of this invention is an imr proved m achine which by reason of itsspeclal construction offers the advantage of as suring a large output and, moreover, a per-1 fectly regular and even apphcatlon of the" paraflinwax whatever may be the quality of the paper even when the latter is notwell calendered. e

Theimproved machine isessentially char;- acterized by the combination: l

(a) of a cylinder furnished with a blanket of woolen fabric, cardboard or other flexible soft material intended to convey the sheet tobe waxed and to afford a soft or yielding supporting surface for the latter while it is submitted to-the action ofwax ing rollers.

(b) of waxing rollers rotating at pe ripheral velocity which is greater than that of the said cylinder.

By reason of this combination the waxing rollers exercise frictlon on" thesheet of paper and since the surface supporting this sheet is of a soft or yielding character this fric tion is applied in a uniform manner over all that under these" the parts to be waxed so conditions the waxing is always effected in a very rapid and perfectly regular manner whatever This' improved machine is alsocharacten izedby a special manner in which the cylin' der conveying the sheet to be waxed is: mounted, which permits this cylinder to be removed out of contact with the waxing rollers when there is no sheetof paper un= der treatment in the machine.

The accompanying drawing shows by way of example one constructional form of the improved machine, in which-- Figure 1 is a front view and Fig. 2 side view thereof.

"Fig, 3 shows a transverse section drawn a may be the quality of the paperg toan enlarged scale, taken on the line 3--3, Fig. 1.

1 As shown in this drawing, the machine comprises a frame a carrying at its ends two guidewaysb; b in which are situated sliders 0;, 0 forming shaft bearings; in these latter the ends of a shaft can rotate freely, and this; shaft carries a cylinder 6 furnished witha blanket f of woolen or other soft ma terial. a i i a a a The sliders a, 0 rest respectively on two eccentrics g, g keyed on two shafts h, h car- ,riedon the guideways b, b these two shafts are connected together by a rod 2' pivotally connected at its two ends to two arms 9', 3'' respectively keyed on the two shafts h, it. An operating lever is movable about a pivot pin Z carried on the frame, is connected by a rocl m tothe pivotal connection ofone of these arms j with the rod '5 in such a manner thatby moving this lever a simultaneous angular displacement is communicated to both eccentrics g, g whereby a rising ior falling movement is communicated to the sliders-0, c and consequently to the cylinder e, as hereinafter mentioned.

Above the cylinder 6 is arranged an in clined feed tablen on which are placed the sheets to be waxed, before they are fed to the machine.

A series of endless cords opassing around suitably placed idle pulleys p retain the sheet of paper in contact with the exterior surface of the blanket f carried by the cylinder 6, during the working period. a

The cylinder 6 receives itsrotary movement from a transmission shaft q carried by the frame of the machine, through a belt 7" passing around pulleys s, t respectively keyed on the shafts q andd. Below the cylinder e the framecarries a hollow sh aft rotating freely in bearings u, o" fined on the guideways 79, b and carrying rollers wsuitably spaced apart; this hollow shaft receives its motion of rotation from the transmission shaft g through a belt a and pulleys y, a keyedrespectively on this shaft a and on the shaft to; the diameters of thepul leys are determined so that the pe ripheral velocity of the rollers w' is greater than that of the blanket f carried by the cylinder 6. Thehollow shaft a is heated internallyby circulation of warm air, water, steam or other fluid.

a cylinder 1 furnished with a woolen covering 2 and dipping into a tank 3 containing paraflin wax heated by a row of gas jets 4. This cylinder is driven by the shaft 9 by means of a belt 5 and pulleys 6 and 7.

Opposite the rollers w are mounted doctor rollers 8 adjustably mounted on a fixed support which permits the thickness of the layer or coating of wax deposited on each of these rollers w to be regulated.

The operation of this machine is as follows:

The sheets of paper to be waxed, placed on the table u are pushed forward one by one until they come against the cylinder 6 and are seized between the latter and the cords 0, an extension of which also assists in conducting the sheets away. Each sheet of paper thus carried along is subjected to the action of the waxing rollers to, which are rotated at a peripheral velocity greater than that of the cylinder 6, as herein above mentioned, and exercise friction on this sheet While at the same time they deposit the wax with which they are coated.

On leaving the machine each waxed sheet is conducted away by a series of cords 10 and placed in a collecting box.

The sheets to be waxed, instead of being fed to the machine by hand, may be introduced mechanically by an automatic apparatus for feeding sheets one by one from a pile, similar to those employed in printing machines.

When the feeding of sheets of paper into the machine is stopped, the lever is moved in such a manner that it raises the cylinder 6 and thus contact of the blanket f against the waxing rolls to is prevented.

It is to be understood that the arrangement hereinabove described is given only by Way of example and that the form, dimensions and details of construction of the constituent members of this machine can be modified.

What I claim is:

1. A machine for waxing sheets of cigarette paper, comprising in combination, a rotary cylinder, a blanket of yielding material, adapted to convey the sheet to be waxed and provide a yielding supporting surface behind the latter during the waxing operation, and waxing rollers adjustably mounted and rotating with a peripheral velocity greater than that of the said cylinder and exercising friction on the sheet of paper and simultaneously applying the wax.

2. A machine for waxing sheets of cigarette paper, comprisincr in combination, a rotary cylinder, a blanket of yielding material, carried thereon and adapted to convey the sheet to be waxed and to provide a yield ing supporting surface behind the latter during the waxing operation, waxing rollers mounted to rotate with a peripheral velocity greater than that of the said cylinder and exercising friction on the sheet of paper and simultaneously applying wax, and means for separating at will the conveying cylinder from the waxing rollers when the feeding of sheets of paper into the machine is stopped.

3. A machine for waxing sheets of cigarette paper, comprising in combination, a rotary cylinder, a blanket of yielding material surrounding the ame, a feed table above said cylinder, idle pulleys, endless cords passing around said idle pulleys and adapted to retain the sheet of paper in contact with the surface of the blanket during the working period, waxing rollers, means for transmittin rotary motion thereto whereby their perip eral speed will be greater than that of the blanket, and means for separating at will the conveying cylinder from the waxing rollers to prevent contact of the cylinder blanket with the waxing rolls when feeding of the sheets of paper into the machine is suspended.

4:.
