CHA|N-MACH|NE FOR THE MANUFACTURE OF CORRUGATED CARDBOARD.

Specification of Letters Patent.

Patented Jan. 23, 1906.

Original application filed April 1,1903, Serial No. 150,660.- Divided and this application filed August 31, 1904. Serial No. 22 2 900- To aZZ whom, it may concern.-

Be it known that I, OAMILLE THIEBAUT, a citizen of the French Republic, residing at Vitry-sur-Seine, France, have invented certain new and useful Im movements in Chain- Machines for the Manu acture of Corrugated Cardboard, of which the following is a specification.

v This invention relates to improvements in chain-machines for the urpose of obtaining a novel corrugated cardboard.

Plaited, waved, or corrugated cardboards as hitherto manufactured do not present sufficientrigidity for large packages. It is true that in some cases there has been stuck to one or both sides of sheets of corrugated cardboard a smooth sheet uniting all the corrugations situated u on the same side; but the product so obtained is expensive, inextensi- 1e, and only imperfectly resists compression exerted at right angles .to the original plane surface 'of the corrugated sheet.

' compressionwhich it may have to support The conditions which should be fulfilled by corrugated cardboard are as follows: first,

the cost rice should be exceedin ly small;

second, t e weight should be as sma l as possi-' ble; third, the cardboard should present the greatest possible resistance to theeiforts of either in the direction of the original p ane surface before corrugation or at right an les to this planeyfourth, constant extensibi ity for the purpose of permitting the cardboard view showing the relativev to be shaped asregularly'aspossible to the objects to be packed and of causing it to assume the form of packages of the most various kinds, such as fia ons or bottles. I obtain a cardboard fulfil ing all these conditions by means 'of the improvement in known chainmachines hereinafter described.

In the accom anyin drawings, Figure 1' is a section on the ine A F of Fig. 2. Fi 2 is a lan view of my novel corrugated car board. igu3 is an elevation of the fluted shaft for driving the endless chains. Fig. 4 is a planpositions of the fluted-shaft and itsendless chain, and Fig. 5 is a sectional view showing two endless chains pressing a sheet of cardboard; Fig. 6 is a sectional view of theendless belts and rollers,-

showing the fluted arrangement of the same; and Fig.7 is a plan view of one of the rollers.

In chain-machines the driving is effected by means. of gear-Wheels cast upon a shaft.

treated is of small thickness, the folds or undulations are produced without difiicult'y;

When the paper or o er su sEi'nce id 2;

but,when the substance to be treated is of hich it affords in the operation of the ma.

0 inc, permits of obtaining a corrugated cardboard resenting all the characteristics enumerated above. It permits in particular of giving to the blades of the chains absolute rigidity, obviating give, so as to certainly effect the displacement of the cardboard and the ressing action of the blades. This novel cardboard is provided in the usual manner with corrugations, which areformed' alternately above-and below the original plane of the sheet; but instead of being smooth and continuous throughout their length these corrugations are formed with protuberances,ribs, or projections f at greater ,or le'ssintervals one from the other, which, so to speak, convert each of the folds, undulations,.o r corrugations. into a reinforced beam and the sheet of cardboard as a whole into a series of rigidly-connected reinforced beams. It will be readily understood that these protuberances impart to the corrugations considerable capacity for resisting pressure which may be exerted in a direction at right an les to theoriginal plane of the sheet-of card oard and that they render unnecessary the employment of the auxiliary sheet of cardboard stuck to the summits of each of the corru ationswhich has been referred to above.- File absence of this reinforcin -sheet results in a diminution of weight and reduction of the cost of manufacture, since the protuberances in question are obtainable in a single pressing operation. These protuberances also impart to the sheet perfect extensibility and permit it to adapt itself to all kinds of packages.

Too

Having now particularly described and as' certained the nature of my said invention and in what manner the same is to be performed, I declare what I claim is 1. A machine for the manufacture of corrugated cardboard, having the driving-shaft provided with grooves throughout their entirelength, cha1ns passing over said dnvingshafts having on their under side-grooves corresponding to the'grooves of theshafts, and means for passing a sheet of cardboard between the chains of the machine.

2. In a chain-machine for the manufacture of corrugated cardboard, grooves on the entire length of the driving-shafts, engaging corresponding grooves of the under sides of the chains for the purpose of moving the latter.

3. Ina machine for the manufacture of corrugated cardboard or paper, the combination of a plurality of endless belts having corrugatedv outer faces and grooved inner faces and arranged one above the other with their adjacent runs in contact, and a plurality of A rollers for supporting and driving the belts, and provided with grooves coacting with the grooves of the belts.

4. In a machine for the manufacture of corrugated cardboard or paper, the combination of a plurality of endless belts havin undulatory corrugations on their outer aces and grooveson their inner faces and arranged one above the other with their adiacent runs coacting.

In witness whereof I havc'hereunto set my hand, in the presence of two witnesses, at Paris, France, this 13th day of August, 1904.
