6' Claims. 1.
This. invention relates to new and. useful improvements in a hemming attachment for an automati: feeding and sewing machine.
More specifically, thev invention proposes. the provision of a folding member used in conjunction with a transverse folding bar for forming a transverse fold in a. moving web of cloth material. It is also proposed to provide a transverse guide rod beneath and to the back of said folding bar for guiding said cloth web to said bar.
The invention proposes to characterize the folding member by the fact that it is mounted upon one end of said transverse folding bar and acts, to fold, or bend a longitudinal edgev portion of said moving web upon the remaining portion of the web.
It is proposed to so construct the folding memher that it may be shifted slightly on said folding bar to better control the folding operation.
The folding member is arranged with a base wall having a bottom flange bent inwards from the front edge thereof and covering the front edge of the folding bar at one end. Said base wall has its outer. end continuing into an end curved portion. which continues into an overhanging top portion upon which an internal bending portion is mounted for forming a iongitudinal edge fold. It is proposed that. the. bottom flange of said folding member continue over said overhanging portion which assists in reversing and bending the. edge portion on the moving web to form the fold.
The folded edge portion as formed by this hemming attachment may then be guided to a sewing machine which automatically sews it down.
Still further this invention proposes the construction of a hemming attachment as briefly described which is simple, efiicient in operation, and which may be manufactured and sold at a reasonable cost.
For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appendedclaims in which the various novel features of the invention are more particularly set forth.
In the accompanying drawings forminga material part of this disclosure:
' Fig. l isv a perspective view of a hemming attachment constructed in accordance with this invention, to which a moving web has been schematically added.
Fig. 2 is a plan view of the folding member of the hemming attachment, illustrated per se.
Fig. 3 is a bottom view of Fig. 2.
Fig. 4 is a side elevational View looking in the direction of the line 4-4 of Fig. 2.
Fig. 5 is a front elevational view of the folding member looking in the direction of the line 5-5 of Fig. 2.
Fig. 6 is a rear elevational view of .Fig. 5.
Fig. 7 is a fragmentary plan view of the hemming attachment applied to an automatic sewing machine in accordance with this invention.
Fig. 8 is an enlarged vertical sectional view taken on the line 8-it of Fig. 2.
Fig. Q is a fragmentary enlarged vertical. sece tional view taken on the line 8-9 of Fig. '7.
Fig. 10 is a fragmentary schematic plan view similar to Fig. 2 but illustrating the first step in applying the cloth web to the folding member.
Fig. 11 is a fragmentary view similar to 1 but showing the moving web fully applied.
The hemming atta :hment in accordance with this invention, includes a transverse folding bar 15 for forming a transverse fold it in a moving web 01 cloth material 11. A transverse guide rod 18 is located beneath and to the back of the front edge of said transverse folding bar it for guiding said cloth web to said bar If. A folding member if! is mounted upon one end of said folding bar it. This folding member to has a. base wall tachment.
25 provided with a bottom flange 22 which is bent rearwards from the front edge thereof and which covers thefront edge of said folding bar it at one end of the folding bar it. The folding bar l5 and the guide rod it are of a relatively great length so that wide. webs of cloth material may have their edges folded with the hemming at- For example, the bar it and rod 18 may be as of asufficient length so that window curtains may be hemmed with the-instant hemming attachment.
The base wall 2! has its outer end continuing into a curved end portion 2 which continues into an overhanging portion 25. The bottom flange .22 continues at one end into an overhangingtop portion 26 which is triangularly shaped and forms a bending or reversing portion. This triangular shape top portion 26 may be clearly seen in Figs. 1 and 2. The back edge of the triangular shape top portion 26 is provided with a guiding lip 2! against which the edge of the web engages and is guided.
An'internal bending portion, 28 is mounted within the overhanging top portion 25 for forming an edge. fold 29 longitudinal along one edge of said moving web ll. Said overhanging portion 25 continues from. the overhanging top p01- tion 26 into a bent edge, or junction 39 of these parts.
The internal bending portion 28 consists of a Wall portion 34 spaced slightly above the base wall 2| and continuing into a curved end portion 35 spaced slightly inwards from the curved end portion 24 of the base wall 2|, and said curved end portion 35 continuing into an overhanging portion 36 spaced slightly downwards of the overhanging portion 25. The edge 3! of the overhanging portion 35 is connected with and attached to the curved edge 38 of the junction of the overhanging portions 25 and 36 by which the internal bending portion 28 is supported. With this construction there is a space 46 through which the fold 29 of the moving web I! passes, and by which the edge fold 29 is formed.
A lug 4| is secured to the side of the curved end portion 24 by which the folding member 29 is attached to the folding bar l5. This lug l! is provided with a transverse slot 42 through which a, clamping screw 43 is engaged. This clamping screw 43 is mounted upon the end of the folding bar I 5.
The operation of the hemming attachment may be understood from the following:
Fig. should first be studied, and it should be noted that the edge fold 29 is freely passing through the space 40. The moving web I? is free to move through the folding member 20 in this condition. However, when the hemming attachment is working, the parts are in the condition shown in Fig. 11 and to place the web I! in this position, it is necessary that that portion of the fold 29 to the front of the triangularly shaped bending and reversing portion 26 to be folded laterally with the edge A of the fold 29 engagin beneath the guiding lip so that that portion of the fold 29 which is over the bending and reversing portion 26 is opened up and folded down, so that we produce the transverse fold Iii extended across the bend of the flange 22 and also extended across the front edge of the folding bar l5.
The bottom portion of the web I I is guided behind the transverse guide rod l8, and now the web is ready to move. The mechanism for moving the web is not shown in this application since it forms no part of the invention. The web I l is intended to move in the direction indicated by the arrow B. It is intended that the web l! have its folded edge portion 29 engaged through a guide C, see Fig. 7, and then beneath the needles of the twin needle sewing machine D. With this arrangement the sewing machine D may operate continuously and the moving web I! will have its edge folded and sewed down. In this way the web I! is formed with a hem.
While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
Having thus described m invention, what I claim as new, and desire to secure by United States Letters Patent is:

A compact two way hemming attachment, comprising a transverse folding bar for forming a transverse fold in a moving web of cloth material, a transverse guide rod beneath said folding bar for guiding said cloth web to said bar, and adjacent thereto a folding member mounted on one end of said folding bar and having a base wall with a bottom flange bent rearwards from the front edge thereof and covering the front edge of said folding bar at one end, said base wall having its outer end continuin into an end curved portion which continues into an overhanging top portion and said bottom flange continuing over said overhanging top portion into a triangularly shaped bending and reversing portion, and an internal bending portion mounted within said overhanging top portion for forming an edge fold longitudinally along one edge of said moving web.
