b all whom it may concern Be it known that CAMILLF: TI-IIEBAUT, a citizen of the French Republic, residing at Vitry-sur-Seine, France, have invented ccr tain new and useful Improvements in Chzihr. Machines for the Manufacture of Corrie gated Gardhoard,- of which the following isi ibut when the substance to be treated is of a specification. v

This invention relates to improvements inchuiu machines :l'ortl' purpoee of obtaining a novel corrugated card-hoard.

llzuted, waved or corrugated cardboards as hitherto manufactured do not present sut" is there has been stuck.v sheets of corrugated cardboard a smooth sheet uniting all the;- corrugatious situated upon the some side;-

l cieut rigidity for large packages. It true that in some cases to one or'both sides of but the product so obtained is expensive, iii-- extensible and. only 1n1p1l [:tly ?ES1SiS com pression exerted at right angles to the origi-' nal plane surface of the corrugated sheet.

The conditions which should be fulfilled by corrugated cardboardere as followsr First, the cost price shoul'd'be exceedingly small; second. the ri cight should be us'smol'l as possible; third, the cardboard should present the greatest possible resistance to the forts ot ou'ipl'ession which it may have to support either in the direction of the original plane surface before corrugation or at right angles to this plane; fourth, constant extcu sihility tor the purpose of permitting the ijill'llbOilI'tl to be shaped :is regularly as possible to the objects to be packed and of causing it to assume the form of packages of the meet various kinds, such as fizigons or bottles. l obtain a cardboard fulfilling all these conditions by means of the i iproveiucut in known. chain machines hereinafter described.

lo the accompanying drawings: Figure l. is a section on the line A, B, of Fig. 2. Fig. 2 is 21 plan View of my novel corrugated cardboard. Fig. 3 is an elevation of the llutcrl shaft l ordriviug the endless chains. Fig. 4 is :i plan View showing the relative positions of the fluted shaft and its endless hain. Fig. 5 is a sectional View showing two endles chains pressing a sheet of cardllourd. F (l is :1 sectional \'l(\V ot the e'udh-ss belts mo. rollers, showing the fluted arrangement of the some. View oi: one of the rollers.

In chain machines the driving is effected l :by means of gear jtrcoted is of small thickness the folds'or modulations are produced without ditiiculty;

v Wheels cost upon the shaft, -When the paper or other substance'tc'be l cardboard to assume the profile of the olcdes of the chains witl'ioutrupture.

The improvement which I have intro.- ldueed into the construction of machines of this kind consists in providing the driving shafts a with grooves throughout their en tire length in such a manner as to produce the driving of these chains 7) equally throughout their Width. This improvement.

owing to the security which it aftords in tho operation or". the. machine; permits; of obtain-I iug a corrugated cardboard presenting 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 th displacement of the cardboard out. the pressing action of the blades. This novel cardboard is provided in the usual manner with corrugations. which are. formed alternately above and below the original plume of the sheet; but instead of being smooth and continuous throughout their length these corrugations are formed with protuberuuces, ribs, or projections f, at greater or less intervals one from the other, which, so to speak, convert each of the folds, undulations or corrugations into n 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 protuhcrouces import to the corrugw llOflS considerallle capacity for resisting pressure which may be exerted in. a direction at right angles to the original plane of the shcct ot czurdbourd and that they render uunecessary the employment ot the auxiliary sheet of cardboard stuck to the summits of l 1 each or the corrugations WillCfi has been re ferred to above. The absence of. time rem-- facture, since the protuberances in question.-

are obtainable in a single pressing operatlon. These protuberances also impart to the sheet perfect extensibility and permit it to adapt itself to all kinds of packages.

Having now described myinvention what I claim and desire to secure'by Letters Patcut is: g y g 1. A machine for the'l'nanufacture of corrugated cardboard, having driving shafts provided with grooves throughout their entire length, chains passing over'said driving shafts having on their under side grooves corresponding to the grooves of the shafts, and means for passing a sheet of cardboard between the chains of the machine.

2. In a machine for the i'nanufacture of corrugated cardboard or paper, the combination of a plurality of endless belts'having corrugated outer faces and grooved inner faces and arranged one above theother with their adjacent runs in contact, and a plurality of rollers for supportingfland driving the belts, and provided with grooves co-acting with ribs formed by the grooves of the belts.

3. In a machine for the manufacture of corrugatedcardboard or paper, the combination of a plurality of endless belts having undulat'ory corrugations on their outer faces and grooves on their inner faces and arranged one above the other with their adjacent runs co-acting.

4. In amachine' for the manufacture 10f corrugated cardboard or paper" a pair of 1 endless belts eachhaving undulato'ry corrugated'blades on the outer surface thereof, said "belts beingso arranged that a certain part'of one belt will be adjacent to a part of the other belt and the corrugations of the.

blades of one 'belt will intermesh with the corrugations of the blades of the other belt,

having undulatory blades connected to the outer surface thereof,- the opposite surface havin a series of transverse rooves ,a air" of rollers supporting eachlbelt and arranged transversely thereof, said rollers having longitudinal grooves -meshing with ribs 1 formed by the grooves of the belt, said rollers being so arranged that a certain por tion of one belt will be'adjacent to a part of the other and one roller of one pair will be adjacent a roller of the other pair, whereby the blades will intermesh' and will be held with rigidity as they pass over the said rollers.

In testimony whereof I, the said CAMILLE: THIEB-AUT have hereunto set my hand this second day of December 1912. V CA'MILLE THIEBAUT/ Witnesses: v
