LOOP GUIDE AND METHOD OF APPLYING LOOPS TO A MACHINE 2 Sheets-Sheet 2 Filecl March 16, 1959 QWR O T N E v m Patented Mar. 31, 1942 UNITED STATE S PATENT OFFICE LOOP GUIDE AND METHOD OF APPLYING LOOPS TO MACHINES Hugo A. Klahre, Teaneck, N. J., assignor to Consolidated Trimming Corporation, New York, N. Y., a corporation of New York 14 Claims.

This invention relates to improvements in loop guides and to a novel method of applying loops to a machine.

Its object is to provide a simple and inexpensive device for holding the loops of a looped heading and directing them to the path of a movable member of a machine for applying ornamentation to the loops and to the method of using such a device.

Another object is to provide a stationary loop holder with a bifurcated end which straddles a movable die of a fringe machine in such a way that the loops are delivered to a part of such a die one at a time, and are removed from the holder by the movement of the die. 7

Other objects will appear in the following specification in which I will describe certain structures which embody my invention, the novel features of which I will point out in appended claims.

Referring tov the drawings.

l designates the frame of a ball. fringe machine. On it are mounted a reciprocatory forming die having two prongs H and I2, a cooperating plunger die l3 and a pair of knives l4 and 15. These parts are actuated by cams l6 driven from a shaft H.

The forming die is moved from its Fig. 4 position to its Fig. position to embrace between its prongs l I and I2 atuft I8 which is fed downwardly across its path. The plunger die 13 is moved in the opposite direction to first bend into the form of a staple a piece cut off of a wire l9 and to then force the staple around the tuft and clinch it to bind the strands of the tuft together. If a loop is on one of the prongs of the forming die at the time the wire is applied, the loop is bound to the strands of the tuft.

Knives [4 and I5 are then moved to sever a short section of the tuft which has been bound together and to the loop. These parts and their operation are well known and need no further description.

to Figs. 4 and 7.

2B is a tape-like heading having loops 2| pro jecting from one of its edges at spaced intervals. These loops are loaded onto a guide rod 30, as shown in Fig. 1. The rod is of sufiicient length to hold a considerable quantity of the heading. The outer end of the guide rod is secured in a clamp 3| in a standard 32 held at a fixed distance from the frame IU of the ball fringe machine by a brace rod 33 with sufiicient rigidity to prevent its rotation. The other end of the guide rod 30 is supported by a pair of grooved rollers 34, 34 on a bracket on the machine frame I0, which bracket is laterally and vertically adjustable. (See Fig. 3.) These rollers form a loose fit with the guide rod to enable the loops 2| to pass.

The inner end of guide rod 30 is bifurcated and shaped to form two. flat spaced fingers 35 which straddle the prongs of the forming die and extend obliquely across them. One side of these fingers is cut back, as at 36, to tfiorm a clearance between them and the prongs II when the die is retracted, as shown in Fig. 4. Their other side is designated by 31. The longitudinal position of fingers 35, in relation to the forming die, may be adjusted by changing the position of the other end of the guide rod in the clamp 3!. The vertical and lateral position of the fingers may be adjusted by some such arrangement as that shown in Fig. 3. The guide rod is sufficiently flexible to provide for these vertical and lateral adjustments.

40 is a roller driven from shaft I! by suitable means, a belt 4| being shown in Fig. 1 as a diagrammatic representation of a mechanism for this purpose. Roller 40 maintains a tension on the heading 2!] in the direction indicated by the arrows.

The operation may be seen by first referring In these figures the dies are in their retracted positions with the fingers 35 overlapping the prong 12. The heading 20 has been advanced by the roller 40 until one of its loops 21A has been pulled off from the fingers 35 onto the prong l2 of the forming die and is held thereon under tension. During this part of the operation there is a slip between the roller 40 and the heading 20. As the forming die advances to the position shown in Fig. 5, the loop ZIA passes with the die between the fingersv 35. At the Fig. 5 position the wire is applied to the tuft l8 and the loop HA and then the wire enin Fig. 7 to the position of the loo-p MA in the same figure and the operation is repeated.

Structural modifications may be made within the spirit and scope of this invention and its use is not confined to the use with the particular mechanism illustrated and described, and I intend no limitations other than those imposed by the appended claims.

What I claim is:
