UNITED STATES PATENT OFFICE.

ADELMER M. BATES,'OF CHICAGO, ILLINOIS, ASSIGNOR TO BATES VALVE BAG COM- PANY, OF CHICAGO, ILLINOIS, A CORPORATION OF WEST VIRGINIA.

BAG-FORM.

Specification of Letters Patent.

Patented Mar. 9, 1920.

To all whom it may concern:

Be it known that I, ADELMER M. BATES, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Bag-Forms, of which the following is a specification.

My invention relates to bag material adapted for use in preparing filled bags which are to be formed from continuous rolls of bag material.

The operation of forming and filling such bags is, of course, commonly carried on by machinery and it is undesirable if not impracticable to print the exterior of the bags after they have been filled.

I have found, in working out my method of making filled bags from continuous rolls of material, that it is highly inconvenient owing to various conditions and business methods which prevail in this art, to print the bag material as part of the immediate process of making and filling the bags. I find that it is better to do the bag printing as a separate process and to feed from continuous rolls of such separately printed bag material into the apparatus for making and filling such bags.

It is, however, indispensable that the printed material on each bag should be properly located on the finished bag, otherwise the finished product will be unsymmetrical. It is extremely dii'licult, owing to the use of machines and the necessity of relying on those who operate the machines, to get this necessary symmetry.

For all these reasons, I have worked out the solution of the problem.

The invention is illustrated in the accompanying drawing wherein- Figure 1 is a dia rammatic representation of a method 0 forming the printed roll;

Fig. 2 is a plan view of a section of such printed roll;

Fig. 3 is a View of a filled bag formed from such roll.

Like parts are indicated by like letters throughout the several figures.

A is a roll of raw or unprinted material, B a printing ap aratus diagrammatically shown through w ich it passes and C a roll of the finished or printed material. D

is the material in question which is shown with the successively printed and similar sections E, E at the side and the intermediate indication marks F which indicate the line of severance. G, G are the stitching line indicator marks placed on o posite sides of the lines F, F in equal distance therefrom. These linesmay be made in any desired manner, the object of them being to clearly show the operator where the stitching and the severing is to be done. One or more of them may be used. The rolls of such printed marked material may be prepared anywhere and apart from or in a factory or building other than that in which the bag fillin and making operation is carried out. he rolls so formed, printed and marked are fed into the ba filling and making machine in any desired manner, and the product emerges as the finished bag with the printed material in every instance in the exact desired position on the bag. The operator has always before him as the work progresses the mark or marks indicating where the goods is to be stitched or severed or both, so that the roll will always be placed, by him, in the proper position to insure the desired symmetry.

The printed material, in a roll, and in actual practice, is first folded and stitched so as to form a tube with the seam outside and the printed matter inside. This tube is then reversed so as to bring the scam inside and the printed matter outside. The bags are then formed by successively depositing in the tube a series of measured quantities each of which occupies a section of the tube and the tube is so manipulated that the printed material comes into proper position on the outside of such tube. Two seams are then run across the tube, between successive charges and between the seams the bag material is severed and by continuing the process a series of bags will be produced from this material. This stitchmg and severing operation is made certain by the presence of the marking lines or marks so as always to bring the printed material into symmetrical relation with the edges of the side of the bag.

I have spoken of the roll of material but, of course, it will be understood that by that.

term I mean to indicate any strip of material of any length or size or shape, roll or otherwise.

I claim:

As a new article of manufacture, a. roll of bag material, adapted to be impressed, folded, severed and sewed by a continuous series of steps to form separate bags, provided with a series of transverse in icating markings, which divide it into uniform successive areas for the direction of the operator, and a series of separate uniform impressions containing matter appropriate to such pro-posed bags, arranged substantially in the middle of successive areas bounded 15 each by the indicating markings, the longitudinal edge and the middle line of the roll. In testimony whereof I affix my signature in the presence of two witnesses this 20th day of March, 1919.

EDNA B. PETERSON, AGNES C. LARSEN.
