A

rllhis k; lie lier is being formed and as op and side members are being stiched g'ehef, wherebv the hat-lining` may' be coinplee in. one opera'fion on a sewing machine.

To he aainznen of he ends in view ehe Afolder is constructed with a base and a body 'formed willi an Sshaped passageway bav- L. relatively wide lower run and relao y narrow in"erniedia'e and upper runs inclined downwardly howard the delivery end of the folder. cord-guide is preferably provided between the relatively narrow upand intermediate runs to lead draw- L /k1; l l l c rr. between the upper and intermediair n ies of the f-fold forined at the edge or" the Jnrip. The folder is also preferably provided acen' Jehe upper run with a laterally eX- 'ending supporting surface upon which the op-inernber of the lfiaoliningry may rest as it is being presenred together with 1'ehe folded strip to the sewing mechanism oi the Inachine with which ille folder is assembled. lit is preferred to provide )che sewing` machine wi'h a presser-'licorJ having an edge-guide for the top-member of the hat-lining to search 192i.

In the accompanying drawings illustrating; the preferred einbodiInenl1 olf "alle invention, l is a top plan view of a sewing in`r chine work-slippers witli the 'folder secured working` position thereon. Fig. 2 is a side elevation of the same. Fig. 3 is a from elevation. 4, 57 6 and 7 are, especiively, j:sransverse sections on the lines '-ili 3*5. 6 6 and 7 7, Fig. l. Fig. 8 is perspectiye view ore a novel hat-lining in is referred @erin as 'produced in one operaby ineens oifthe present improvement. 9 is a section through jdie seani of the body 9 orined with spaced walls dening an S-snaped passageway having a relatively de lower run 10 and relatively narrow ininediae and upp runs il. and 12, respec- 'iv ly; 'ghe latter aperingi downwardly to- 85 w @he level of Jdie lower run l0 at the d .n U end oi the `older. Positioned be- Jween libe upper and intermediate runs 1l.

and l?, of the passageway is a cord-guide 14 which leads the cord c between Jche upper and intermediate plies l5 and 16,. respectively, oi ehe 'folded side strip s. Associated wil-l1 elle cord-guide le is second cordguideway 15 formed near the delivery end of the folder. The cord-guides l-l and l5, being in substantial alineinent, may9 for all ingents and puiL oses, be considered as a singie cord-guide inawo sections positioned besween Upper and .intermediate runs l2 and l1 of 'lle folder.

7. rl, strip-folder for sewing machines having a base and a body formed with spaced walls dening in cross-section an S- shaped passageway with closed ends, the lower run of said passageway being extended to one side beyond the intermediate and upper runs, and a work-support above the upper run and extending laterally at the other side of the intermediate and upper runs.

8. An attachment for sewing machines comprising a strip-guide having a relatively wide run for guiding the relatively wide side strip portion ot a hat-lining, vand other relatively narrow communicating runs for guiding a folded insert strip portion adjacent one edge of the side strip portion, a cord guide intermediate the runs for said insert strip portion, and an edge-guide disposed between the projected boundary lines of the narrow runs.

9. rlhe combination with a sewing machine having a reciprocating needle, feeding mechanism, and a presser-toot, of an edgeguide, and a strip-folder comprising spaced walls deiining an-shaped passageway, said folder and edge-guide being so related to one another and to the needle and pressertoot that the edge-guide lies between parallel lines deiined by the edges ot the upper ply ot the folded strip passing through the folder, and that the needle lies between par'- allel lines defined by the edge-guide and the tree edge of the upper ply of said folded strip.

In testimony whereof, l have signed my name to this specicationonanLns `wiNKnLiman.
