PACKING OR LINING- MATERIAL AND THE ART OF PBODUCING THE SAME.

Specication of Letters Patent.

AppIicaton led April 15, 1918. Serial No. 228,622.

To @ZZ whom t may concern Be it known that L'JAcoB GERmrsoN a citizen of the United States, residing at Kankakee, in the county of Kankakee and State of Illinois,.have invented new and useful Im-V provementsl in Packing or Lining Materials and the Art of Producing the Same, of whichthe following is a specification.

i The present invention relates to packing or liningI material and to the art of producingthe same, and has for its objectsthe production of composite sheet structures of serviceable character and of forms which provide for the desired packing protection and are at the same time more or less pliable or flexible to permit manipulation during packing operations.

Further objects are to produce composite sheets of this character in a simple and eiicient manner and at relatively low cost.

To these and other ends, the nature of which will be readily understood as the inf vention is hereinafter disclosed, said invention consists in the composite sheets and the methods of manufacture hereinafter more and of thin pliable or flexible material' united by units c of geometrical contour and preferably of uniform thickness, the units being spaced apart and arranged on geometrical lines so that the composite sheet can be folded or manipulated on lines which are located intermediate rows of units.

The particular arrangement of the geometrical units may be varied to take care of particular conditions, but the generall preferred arrangement is such as to locate the units in parallel rows and on lines which intersect each other at approximately right angles.

he units are preferabl in the form of disks of circular contour, t us presenting no sharp angles to damage the thin sheets or affect the manipulation of the composite sheet.

By this arrangement, the thin sheets are held positively spaced apart at the points of location of the disks, and being adhesively secured to the disks, these particular portions provide practically a solid thickness to the composite sheet. IHOWeVer, the portions of the thin sheets which are not adhesively Patent-ea Mar. 29, 1921. u

connected to the disks retain their flexible character, and since these portions of the sheets are normally not connected together, the composite sheet can be bent or folded in either direction between adjacent rows of disks, since the spacing between the sheets at such point is such as to permit the thin sheet of the inner side of thefold to move toward that of the outer side and thus prevent placing any ymaterial strain or tension on the structure such as might tend to break or tear the thin sheet. -Anol since the units are arranged in rows extending in different direc tions, the sheet can be manipulated to meet the vari-ous conditions of use.

As will be understood, the serviceability ,of a vcomposite sheet of this type depends f more or less upon the accuracy with which the unitsare positioned, and this factor becomes of material importance in the commercial use of the sheet. This will be understood from the fact that it is designed more particularly for packing or lining purposes,

and should therefore be of low cost in manufacture. On the other hand, the necessity for more or less'accuracy in position of the units would., in case of hand manufacture, practically negative such low cost because yof the time required in producing the structure as well as the production under comparatively low capacity conditions.

For'these reasons, as well as to provide for decreasing the cost of manufacture, I preferto produce the composite sheet substantially in the following manner, thereby not only providing for manufacture under low cost conditions, but in addition 'making possible the production of another product which is serviceable for lining conditions. although the sheet may be otherwise produced.

One method I prefer to employ is to form the units or disks from a sheet 0l of heavy stock of suitable material. such for instance as cardboard, pasteboard, etc. by a punching action, preferably employing a plurality of punches 10 of the desired size and configuration, these punches being arranged somewhat in the nature of a gang punch. the individual punches being arranged to duplicate the spacing of the units or disks of the composite sheet. For instance, the punch may coinprise a single punch, a single row of punches. ora plurality of rows of punches, the latter providing for maximum capacity conditions. vThe punches are preferably located to cooperate with a complemental die, indicated at 11, and the sheet 0f stock-Which may be considered as a foundation sheet-is placed on the die plate. Beneath plate ll I support one of the sheets-c or b-preferably With its upper face adhesively coated. thus exposing this coated face to the units or disks Which are punched from the founv dation sheet by the action of the punches. the

v into the die plate.

units or disks passing through the die plate and on to the positioned thin plate, the latter bein properlyspaced from the bottom of the (Iie plate in order to permit the desired action, thus applying the disks by a more or less pressure action.

Obviously, should t-he die plate have a thickness greater than the thickness of the units or disks, and the length of punch movement be such as to retain a disk or disks Within the complemental perforation of the die plate, the general result will be the saine. the particular disks to be applied being the lower ones of the die plate. Whether this one be that Which has just been taken from the foundation sheet or one which has been brought to the applying position through the successive introduction of additional disks In this latter case the die member may be considered somewhat in the character of a magazine. the magazine forming a supply source for the disks. the

geometrical arrangement of the individual supplies providing for the proper arrangement of the disks on the thin sheet. .and While I prefer to provide the disk-producing and disk-applying inthe same apparatus and inthe manuel1 indicated. it Will be readily understood that the invention is not limited inlthis respect, since the disks may be formed separate and then introduced into the several suppplies, after which the individual applicatlon ywould be made by plungers or pressers of thegeneral type of the punches here- -tofor'e referred to, it being readily understood that in either case, the disks are apniied by pressure and adhesively secured to the posltioned thin sheet With the disks arranged on geometrical lines and isolated from each other.

After the disks have been so applied to the positioned sheet, the latter is removed and anothel` thin sheet adhesively applied to the opposite unapplied faces of the applied disks. thus completing the sheet.

The advantage of the preferred arrangement lies in the fact that the desired arrangement of the disks or units is practically provided before the punching action has been had. If a single punch is employed, the foundation sheet can be properly marked on the desired geometrical lines or a tein- Dlet be employed. If a single row is being` utilized` the units of that row will be siinultaneously applied and by shifting of punches or of sheets. the proper spacing of the adjacent row can be had. Where the gang punch comprises a plurality of rows, the units or disks of a definite area of the composite sheet will be properly positioned concurrently.

The thin sheets may be of paper or of other material. The foundation sheet may also be of suitable material, but, by reason of the general arrangement of the composite sheet. this foundation sheet may be formed of practically waste material, scraps, etc. which are left over in the formation of some other article. For instance, if the general manufacture is' of pasteboard, the waste material can be employed for this purpose, so that the composite sheet is practically the Waste material disks or units and the thin sheets of material, providing for a lou' cost of material required.

While I prefer to employ an adhesively coated thin sheet and apply the disks thereto. it will be readily understood that this may be reversed. and the faces of the disks carry the adhesive andthe thin sheet remain free from adhesive, the essential feature being to adhesively connect the disks to the substantially flat sheet.

In addition. the foundation sheet d may, itself. form a distinct product by covering its opposite sides with thin sheets c of material. thus closing the-openings al formed during the disk-punching operation and producing a more or less rigid structure of considerably reduced weight and yet having practically all of the supporting qualications of a solid foundation sheet used for lining or other packing purposes, the spacing of the openings being on the geometrical lines and spaced apart so as to provide no material Weakness to the product. I have not herein specifically claimed this additional product, said product forming the subject-matter of aseparate application.

From the above it will be seen that by the use of a foundation sheet of heavy stock, and three sheets of light weight flexible material such as paper sheets; I am able to produce packing or lining sheets of two different types, one being non-flexibleinore or less rigid in character-and the other flexible; that these results are obtainable in a simple and inexpensive manner as respects the cost of material and labor, and, since the foundation sheet may be of waste material, the resulting products are practically a by-product of 'a general line of manufacture. And, as 'Y will be readily understood, the methods above pointed out provide for the production under maximum efficiency conditions, in that the entire foundation sheet is put to use in serviceable forms, and with .the least expenditure of time.

As will be understood, the thin sheets may be of any desired flexible material, as for instance fabric, paper, etc., the general formation of the composite sheets being such as to permit the use of paper for the purpose and at the same time provide a structure of suflicient strength for ordinary ffl@ usages.

Ubviously, the composite sheet may be of any desired dimensions, it being readilyy understood that such sheet can be cut into smaller dimensions at the will of the user.

While I have herein shown and described packing or lining materials as articles of manufacture, together with various wa s in which they may be produced, it wil be readily understood that changes or modifications therein may be found desirable or necessary to meet the exigencies of use, and I desire to be understood as reserving the right to make any and all such changes or modifications as may be found desirable or essential, in so far as the saine may fall within the spirit and scope of the invention as expressed in the accompanying claims when broadly construed.
