8 Claims. (Cl. 154-1) Our invention relates to new and useful improvements in a machine for the manufacture of rugs, and more particularly to a machine for applying either a layer of fabric (burlap) over the rear surface of the pile fabric to act as a base or applying this fabric and also a felt base and simultaneously cementing the pile fabric, intermediate layer, and-the base into substantially one integral structure.

Another object of the invention is to provide a machine to which a strip of pile fabric is fed while, at the same time, there is passed through the machine a further fabric (burlap) that is cemented to the pile fabric, this fabric acting as a back, as will be explained. The pile fabric may then be stored and sold in this condition or it may later be run through the same machine and a further felt back cemented thereto.

Still another object of the invention is to provide a machine through which a, strip of pile 'fabric is fed, while simultaneously there is added a further fabric strip (burlap) and a felt base, the several parts being cemented to form an integral structure on the one course through the machine.

Still another object of the invention is to provide a machine, wherein a pile fabric with outstanding integral marginal strips (which are not tufted) may be passed through the machine, the machine, in turn, automatically turning over these marginal strips and cementing them to the pile fabric. Also, during the course of the pile fabric through the machine, a further strip of fabric is cemented in place and a felt back added, if desired.

Still another object of the invention is to provide a simple and inexpensive machine, wherein a roll of pile fabric, a roll of burlap, and a roll of felt are automatically passed through the machine, the roll of pile fabric first having its marginal side strips coated with acementitious rubber. Then as the fabric continues through the machine, these marginal side strips will be folded back on the fabric and cemented in position. The, roll of burlap is then applied to the back of the pile fabric, cemented in position and, at

the same time, a layer of felt is applied, so that the pile fabric now, when delivered from the machine, will be in the form of a completed strip to be made up into rugs or carpets.

Still another object of the invention is to provide a machine through which is fed the pile fabric, burlap and felt, the machine automatically folding and cementing the side marginal edges of the pile fabric, impregnating an intermediate layer of burlap with rubber in liquid form, and cementing the same and a felt back to the strip all during the one course through the machine.

Still another object of the invention is to provide a simple form of machine, wherein the pile fabric is fed from a roll at one side of the machine, passed over rollers so that the protruding marginal side edges may be gummed, and folded back on the pile fabric, after which a strip of burlap, which in turn has passed either over or under a roller, depending on whether both sides are to be coated, with a strip of felt are passed between rollers, together with the pile fabric, so that the several parts may be tightly pressed and cemented. The strip is then mechanically fed from the machine and mechanically fed onto a roller and stored until desired.

Still another object of the invention is to provide a relatively simple machine that will fold and cement the protruding marginal edges of a strip of tufted fabric and then cement either one layer of burlap or a layer of burlap and felt and then wind the completed strip on a roll at the end of the machine.

Still another object of the invention is to provide a simple machine for attaching a burlap strip and a felt base to a pile fabric, the article itself forming the subject-matter of an application filed by us on June 4, 1935, hearing Serial Number 24,940, for Rugs and carpets.

Still another object of the invention is to provide a machine for especially attaching an intermediate strip or base to a pile fabric, the pile fabric, in turn, being made on a loom which forms the subject-matter of a separate application about to be filed by us in the United States Patent Office.

With these and other objects in view, themvention-consists in certain new and novel features and combination of parts, as will be hereinafter more fully explained and pointed out in the claims.

Referring now to the drawings showing a preferred embodiment,

in line with the roller 51 is another roller 58.

- Likewise, in line with the trough 50, and to the left thereof in Fig. 1. there is another'guide roller 59, and to the right thereof is the roller 50, so that the pile fabric when entering the machine may pass over and under these rollers, as will be shortly mentioned.

Located between the rollers 59 and 60, there is mounted, as at 6| a folder 62, which is formed of metal, in the usual manner, having the bottom 83 and the flaring and folded-back wings 64, so that when the strip of pile fabric 55 (Fig. 3) passes through this folder, the marginal edges 54 will be folded back on'the pile fabric. The shaft 52 with its rollers 53 mounted in the trough 50, which is filled with a rubber cement, will apply the cement to the marginal edges 54, and the folder 62 will turn back these edges, which will afterwards be compressed by the rollers 41 and 35.

Now mounted in front of the machine is a support 65 having the bearings 66, in which the roller will be mounted and on'which has been wound the pile fabric 55. Suitably mounted above the machine in a hanger 68 will be mounted a roll of burlap 69 and a roll of felt I0, so that a burlap strip 69 may be impregnated and cemented to the pile fabric 55 and so that simultaneously there may also be applied to the pile fabric a felt base I0.

Before tracing the course of the several strips of material through the machine, it might be stated that if just the burlap is to be cemented to the pile fabric 55, then it is only necessary that the burlap be coated on its one face with the cementitious rubber, and in that instance, the burlap 69 will take the path shown by the dotted lines, and pass under the roller 48 and then be by-passed up over the roller 46 and then under the roller 49, whereas if the felt backing is to be applied at the same time, then the burlap strip 59 (which will now act as an intermediate layer) must be coated on both its sides, and in this instance, instead of passing it over the roller 46, it will be fed down past the roller 48 and under the roller 46 and then under the roller 49.

In Fig. 1, there will be noticed right below the roller 49 a small scraper 1|, between which the strip will pass, so that any superfiuity of rubber cement may be scraped from the burlap before it is cemented under pressure to the pile fabric. Likewise, in the lower trough that cements the marginal side strips may be seen a further scraper l2.

Referring for the moment to Figs. 5 to 10, inclusive, there will be seen, as heretofore mentioned, the pile fabric 55 with the stitches 56 to form the pile 56', while in Fig. 6, there is shown the marginal edges 54 turned back on the pile fabric and cemented thereto. Likewise, there is shown the intermediate strip of burlap 69 with its cementitious coating of rubber thereon, the burlap being rolled back for the sake of clearness. There may also be seen the felt base 10, which may be of any desired make, but preferably a felt with the pockets pressed therein and known to the trade as Ozite.

In Fig. '7, there is shown the completed rug or carpet strip, the pile 56, however, not being trimmed, whereas in Fig. 8, the pile fabric has been trimmed by regular rotating blades (not shown).

As set out in the companion application on the article, shown and described in the application filed by us on June 4, 1935, bearing Serial Number 24,940, for Rugs and carpets, by turning back these marginal edges 54 and still leaving a slight projection of the edge, which is not tufted, a number of strips of the finished material can be sewed, as at 13, so that the seam will not show through the pile.

We have found that the best cement to be used in cementing the marginal edges, the intermediate strip, and the felt back is known in the trade as Statite", it being a rubber cement in liquid form, which changes from liquid to elastic form when exposed to the air. Thus, by impregnating the intermediate strip 69 with this rubber, not only are all of the stitches held in their places, but there is an elasticity and softness to the rug or carpet that is not otherwise possible. Again, by impregnating the burlap strip 59 with a rubber cement, there is a firmness and rigidity given to the article that would not otherwise be present, and the rug or carpet will lie flat on the floor and will not give or wrinkle from footsteps.

Now briefly tracing the movement of the pile fabric 55 through the machine, it will pass from its roll under the roller 51, around the roller 58, and the marginal side edges 54 will contact I with the rollers 53, which aremounted in the trough 50 and thereby apply this rubber cement to the marginal edges. As the fabric travels through the machine, it will next pass over the roller 59 and back through the folder 62, so that the edges will be folded back on the pile fabric, as may be seen from Fig. 3. The pile fabric then passes upwardly and over the roller 4|. Here, it combines with the strip of burlap 59 that is passed under the roller 46, through the trough 44, and under the roller 49, where these two fabrics are then subjected to a heavy pressure in passing through the weighted roller 35 and its complementary After the material passes under the two afore-- mentioned rollers, they will move rearwardly over the roller 28 and about the spike roller Hi, this spike roller drawing the pile fabric, the burlap, and the felt (which it is remembered are now united in the one strip) through the machine.

The finished strip then continues to be wound in a roll 22, and this roll is actuated by the spike roller l9, both of these being driven from the aforementioned reduction gear 5 which, in turn, is actuated by the motor 4.

It may not always be desirable to apply the felt base 10, and in this instance, the burlap strip 63 really becomes the backing or base. As heretofore mentioned, it will then only be necessary to coat the burlap 69 on its one face. To do this, the burlap strip is run under the roller 48 and over the cementing roller 46, rather than through the trough, and then through the machine in the ordinary way.

If, at any time, it is desirable to apply the felt base, the felt would be led under the roller 48, rather than directly under the roller 14, then over the roller 46, and then in through the pressure rollers and firmly cemented to the fabric strip and the pile fabric, in the manner aforementioned.

From the foregoing, it will be seen that we have provided a machine for gumming the outer marginal edges of a pile fabric and then turning these edges back on the pile fabric. As the pile fabric continues to pass through the machine, the strip of fabric is impregnated with a rubber cement and securely cemented under pressure to the pile fabric. Also, a felt base may be applied at the same time or may be applied at a later date, if desired.

We have found that the machine, as designed, is very efficient in service and permits of a great amount of yardage of carpet strips or rug strips being completed in a day's run.

Many slight changes are possible in the construction hereinbefore set forth without in any manner departing from the spirit of the invention.
