M r h 13,. 1945. w. R. SCHINDLER PROCESS FOR MANUFACTURIflG A TYING MEMBER Filed Sept. 25, 1942 Emit iviqzwm NM Hm Patented Mar. 13, 1945 1 UNITED A PROCESS FOR MANUFACTURING TYING MEMBERS Walter R. Schindler, Los Angeles; Calif. Application September 25, 1942, Serial No. 459,696 I 1 Claim.

tional advantage that only one source of supply 7 of paper is used and the same is doubled to secure the necessary laminations. By using one supply or continuous strip of paper in the place of the two strips in my previous patent I am able to place trademarks or other descriptive matter upon the finished tying member. This is not p0s sible with the double paper supply as the markings on top and bottom of the tying member would not align with each other.

In general, my present invention consists of the process and machine for continuously feeding a wide strip of paper which is slit longitudinally, and then longitudinal strips folded substantially at their middle while feeding between each fold a continuous wire. The paper and wires are laminated together with a glueing substance preferably waterproof such as asphalt. By prior slitting of one sheet and folding the strips formed thereby, and by using a cut-off to cut ofi at a predetermined point, my machine is capable of carrying out the process of forming a plurality of tying members comprising flat bands of paper with a wir running through them, and the same are bound together with an adhesive.

My machine is entirely automatic and'needs no supervision. start the machine after inserting the paper and wire and to package the finished article.

In the drawing:

Fig; l is a diagrammatic elevation illustrating my complete machine;

Fig. 2 is an end view of the folding rolls taken on the line 2-2 of Fig. 1;

Fig. 3 is an end view of the glue wheels taken on the line 3-3 of Fig. 1;

Fig. 4 is a cross section taken on the line 4-4 of Fig. 1;

Fig. 5 is a plan view of a tying member.

In the preferred form of my invention a plurality of tying members are made at one operation. To secure this plurality of finished members I use a wide strip of paper I carried on the spool 2. This is fed into my machine between the An operator is needed only to is made of rubber or other substance to give it a grip on the paper 1. After passing through the feed rollers 3 and 4, the paper is divided into a plurality of narrow strips 8 by the slitting cutters 5 and then passed through the feed rolls 6 and 1 similar to rolls 3 and 4.

The individual strips 8 are then fed into the folding rolls 9 and In which comprise a pair of complementary rolls the lower roll 9 having its edge ll tapered to form an inverted V and the upper roll having its edge 12 in the. form of a complementary V. When the strips 8 are passed between the rolls 9 and I0, they are folded into a V shape.

After being folded the strips 8 pass through the guides l3 which comprise complementary V- shaped parts I and [5. At the apex of the V 15 a groove I6 is provided. Into these grooves the wires l1 are fed from the spool l8.

The strips 8 with the wires l1 between the folds thereof then pass between the tarring 7 rolls l9 and 2B. These rolls are identical with thetrolls 9 and III with the exception that the rolls I9 have the grooves 2| to take the wires The lower side of the rolls 19 are immersed in the asphalt bath 22 which is heated by the burner 23. As the rolls 19 are rotated by the passage of the strips 8 between them they paint power driven feed rollers 3 and 4. The roller 3 the molten asphalt on the wires l1 and strips 8. The strips 8 and the wires H are then combined by passing through the pressure rolls 24 and the cooling rolls 25 and the power-driven rolls 26, the latter being identical with the feed rolls 3 and 4.

While all of the rolls can be power-driven at the same speed by one motor, I prefer to drive only the feed rolls 3, 4, 6, 1 and 26.

The slitting cutter 5, the pressure rolls 24 and the cooling rolls 25 are the same as described in my prior Patent No. 2,290,386 and all of the rolls can be journaled as shown therein.

I prefer to place idler rolls 21 on the paper supply -I to maintain the paper taut and idler rolls 28 similarly maintain the wire H.

To prevent waste of material the shut-ofis 29 and 30 on the paper supply I and the wire supply I! are used. These shut-offs are identical with those on my prior machine described in Patent No. 2,290,386. These shut-ofis stop the machine if the paper is torn or a wire broken.

- -A feature of my present invention is that trademarks or other brands 3| can be printed on the -roll of paper and when folded in the machine 2 the tying members will always have the brands 3i opposite each other.

To cut the tying members to a correct size the paper I has marks 32 placed thereon during the printing of the brand. These marks 32 when passed under the ordinary electric eye 33 actuate the eye which energizes the solenoid 34 causing the same to draw down the knife 35 by means of the links 36. The knife 35 cooperates with the shear block 31 tocut the strips: 8.: to the. desired length. After each'stroke of the knife 35 it is returned to its original position by the spring 38. This length is fixed by the position of the mark 32 and the strips 8 are cut substantially equidistant from the ends of the brand 32.

While I have described the preferred embodiment of my invention, I am not limited to the details thereof except as set forth in the following claim. i

I claim:

The process of forming tying members having a printed legend thereon, comprising passing a roll of paper having printed thereon legends in a continuous strip through a slitting 'device and thus dividing said roll into a plurality of narrow strips, said division separating said legends longitudinally, folding said narrow strips longitudinally substantially at their center lines, simultaneously feeding a wire between: the folds of each strip, and painting the wire and interior of the folds with an adhesive, then feeding said strips through pressure rolls to permanently unite said foldedmembers with said wire and adhesive, and cutting said strips transversely between said legends to provide a printed legend on each tying member.
