Application filed September 20, 1924. Serial No. 738,854.

This invention relates. to finishing welts, and a method of making the same, and among other objects aims to provide welt whichis relatively inexpensive to manufacture.

The invention may be'understood by reference to one illustrative embodiment shown in the accompanying drawings, in which:

Fig. 1 is a sectional elevation of apparatus for making welt according to thein vention; I g r v Fig. 2 is a sectional plan view of the same;

Fig. 3 is a section on line 33 of Fig. 1; Fig. 4 is a perspective view of the folder with the parts of a welt being folded thereby; V

. Figs. 5, 6 and 7 are sections on lines 55, 6-6 and 7-7 respectively of Fig. 1, showing the manner in which the welt parts are folded together; a

Fig. 8 is an enlarged sectional view of the completed welt; and v Fig. 9 is a similar view of the welt shown attached to a support. l 1

It is to be understood thatthe illustrative form showninc the drawings is simply one embodiment of the invention; and that in the following explanation of that specific form, the described details of structure and organization are merely exemplary.

sembled welt into the desired final shape and means to unite the parts.

Referring to Figs. 1 and 2, the folder shown comprises a plate or base 10 on which i is secured a tapering shell 11, constructed and arranged for'longitudinal travel of the V welt parts therethrough from the larger end to the smaller, to effect automatically the assembling of said parts. The welt is made from a flexible cover 12, conveniently of imitati on leather; a central core body 13 of some deformable material as loosely twisted. jute fibres. and a pair ofsmaller cores 14 for the marginal beads. A jute fibre is advantageous because it is very easily formed to the required contour and because it less expensive than preformed cores of many other materials. Strips of inexpensive hard twisted paper may be employed for the cores 14.

shown in 1,2 and a the welt parts The apparatus shown for the purpose of are fed into the folder with the cover- 12 surrounding the cores and with the. core 13 between the smaller cores14. The folder has two 21116.98 15, 16 st its end for the cores 14 5),and a longitudinal fin l7 extending from gu1de15 for the principal part oi: the length of the folder to segregate one of the cores 14 from tl'ie'large core 18 during the assembling process. By the folder shown and described, the covering 12 is encircled about the three cores 13, 14 individually; as

illustrated progressively in Figs. 5, 6 and 7 and at the opposite sides of Fig. 4; and the originally round central core 13 is initially shaped somewhat by the oval form of the disject-ing from the folder (Fig. 2,) and thence directly to the mechanism for flattening the welt'and for unitingits parts. In this instance the mechanism for. flattening the welt forms part of a sewing machine, which stitches the cover strip and corcstogether under sufieient pressure to efiect a permanent deformation of the inelastic jute fibre core. Referring to Fig. 1, there is shown the presser bar 20 needlesQl and guide head 22' of a known type of sewing machine. At its lower end, presser bar 20 has a presser foot 23 grooved on its under side for passage of the welt, as indicated at 24. 25 in Fig. 3 and having perforations 26 for the two needles (Fig. 2). The presser foot 23 beats againsta plate 27 designed to support the welt during the sewing operation. and by means of the pressure of a strong spring 28 (Fig. 1), shapes the deformable core 13 tofinal form in which it is held-by the longitudinal row of stitches and by the natural stiffness of the cover material 12. The machine stitches the welt longitudinally as at 29. Figs. 2 and 8, to provide two small marginal beads and a large central beadly'ing between them.

An adjustable set collar on rod 20 for transferring pressure from spring 28, permits an adjustment of the pressure of foot to varv somewhat the firnmess arid final shape of eentralbead. The welt particularly easy to secure because the central bead is hinged, as illustrated in Fig. 9, and may be lifted out ofthe Way until the securing elements 31 are driven, thereafter closing over and completely hiding such elements.

Obviously the present invention is not, re-

stricted to the particular embodiment there-j.

of herein shown and-descrlbed.

Moreover, it is not indispensable that all the features of the invention be used conj ointly since they may be employed advantageously in various combinations and sub-combinations as delined in the claims. a

Having described one invention I claim l. In a finishing WGlll, a finishing bead oomprising'in combination a core consisting of a strand of loosely twisted fiber and covering material surrounding said core and constructed and arranged to hold said core in firmly embodiment of my compressedcondition and in a shape to give the bead the desired contour.

2. As an article of manufacture, a finishing Welt having a bead formed of flexible covering material enclosing a core'consisting of a compressed strand of twisted jute fibers.

3. As an ar icle of manufacture, alinishing We'lthaving a core consisting of a strand ofloosely twisted jute fibers in firmly comv pressed condition. I I

ll As an article of manufacture, a Welt having longitudinal edge beads each With a relatively hard filler; and having a larger intermediate bead with a soft loosely'twisted,

jute fiber filler compressed to make saidbead lirm. v 7
