PATENT OFFICE

Previously used to beautify toilets and protect the edge of robes, Headgear, footwear ,. Used embroidery, linen and other items Ribbons, braids, trimmings, etc. are flat in shape and have only two Sides, a top and a bottom.

If any object is caught with these ribbons, it will either by sewing on once, the fabric and the folded, both sides of the fabric edge piercing the covering tape with the needle, or by sewing twice in the following Way:

i. Sew one of the edges of the ribbon lengthways to the edge of the object to be enclosed.

2. After this first part has been sewn on, the tape is turned over in such a way that it encloses the edge of the object, and then sews on the second edge of the tape the bottom of the material in question.

The first way of edging produces a very irregular work because the worker is forced to keep the ribbon folded; the second method provides a more perfect job, but it takes more time and is consequently more costly.

Whichever of these two procedures one may use, it is always necessary to use the It is better to iron the sewn-on braids with a hot iron so that they lie flat unite the fabric and remove the frizzy spots.

In order to make edging easier, faster, more regular and cheaper, inventors Ribbons, braids, etc., which are folded directly on the lace machine and with or without a central rib. Figs. 1 and 2 of the enclosed Drawings show cross-sections of two bands folded in this way, one with, the other without a central rib.

3 and 4 show a lace machine, which for the production of folded, with central rib provided bands is appropriately set up.

If the ribbon, braid, border, tress, etc. is to be kept folded lengthways so that it shows the cross-section, Fig. 1, it must be passed between two smooth rollers mm, Fig. 5, which it as required fold in two equal or unequal parts. For this purpose, however, a guide η must be arranged in front of the two rollers m , which pre-folds the tape to the extent that it is moved further by the two rollers.

This guide is shown in section in FIG. 6; it consists of two against each other slidable metal sheets, which can be adjusted so that they accommodate what has been drawn between them The tape can be folded lengthways into two equal or unequal parts.

If this tape is sewn to the object to be bound with a single row of stitches on, it retains the appearance of a regular fold and an impeccable

without having to iron the band with an iron. The one with centraler Longitudinal rib tape, Fig. 2, can be made either by weaving or by lace making will.

For the production of ribbons with a central rib, the one in FIG. 3 is used in a vertical section and in Fig. 4 in the basic pattern shown braiding machine.

This machine consists of 36 plates AA. . . A ¹ A ^ A ² , which rotate around pegs α α and are arranged around a vertical central axis, as in the usual braiding machines for flat wefts.

In order to obtain the threads for the rib of the belt, an auxiliary plate B is arranged on the machine next to plate A ¹ , FIG. 4. Each plate A has notches bb. . . two clappers C ¹ C ² ... C ⁷⁶ , which move from one plate to the other. The plates A have 4 notches b, the two outermost plates A ^{2 - 1} each have 5, the middle A ^1, however, only 3 and the plate B has 7 notches. The number of notches b in plate B is determined. the width of the central longitudinal rib of the band to be produced. The plate B can therefore also have 9, 1.1, 13, 15, etc. notches. All these plates rotate around pegs, as in the ordinary machine, and, as in this machine, transport ^{the clapper C 1} ... C ⁷⁶ on between impellers S and the corresponding plate notches, the threads c of these clappers intertwining in one another in such a way that they form the bond. All clappers go through the same path, namely it takes z. B. the clapper C ¹ , starting from the position indicated on the drawing, moving in the direction of the arrows, Fig. 8, one after the other the positions C ¹ C ⁵ C C ⁹ C ¹¹ C ¹³ C ¹⁵ C "C ¹⁹ C ²¹ C ²³ C ²⁵ C ²⁷ C ²⁹ C ³¹ C ³³ C ³⁵ C ³⁷ on the plate A on the left, then the positions C ³⁸ C ³⁰ C ⁴⁰ C «C ³⁸ on the auxiliary plate B, finally the positions C * ³ C ⁴⁵ C ⁴⁷ C ⁴⁹ £ 51 £ 53 £ 55 £ 57 £ 59 £ 61 £ 63 £ 65 £ 67 £ 69 £ 71 £ 73 £ 75 £ 76 _au f J _6n plates ^, and the extremest plate A ² right one, then turns around and always comes back in the direction of the arrows after the outermost plate A ² on the left, one after the other the positions C ⁷⁴ C ⁷² C ⁷⁰ C ⁶⁸ C ⁶⁶ C ⁶⁴ C ⁶² C ⁶⁰ £ 58 £ 56 £ 54 £ 52 £ 50 £ 48 £ 46 £ 44 £ 42 £ 36 £ 34 £ 32 £ 30 £ 28 £ 26 £ 24 £ 22 £ 20 £ 18 £ 16 £ 14 £ 12 £ 10 £ 8 C ⁶ C ⁴ "C ^ C ^ C ¹ occupying, i.e. returning from one end of the machine to the other without passing through the auxiliary divider B. All plates are set in rotation by the shaft D, FIGS. 4 and 8, which carries a fixed and a loose belt pulley EE ^1. At one end of the shaft D a conical gear F is attached, which is in engagement with the gear G arranged on the pin α of one of the plates A. The shaft α transmits the movement by means of a spur gear J to the central gear wheel H.

Through the wheel H three wheels PI ¹ 1 \ which against / by 90 respectively. 18o ° are offset in rotation. The movement is thus transmitted to 4 plates A , which are in engagement with all other plates AA ... A ¹ A ² A ² in turn by gears /, Fig. 3, which are arranged on the pin α. A gear attached to the shaft of plate B causes it to take part in the rotary motion of the other plates. This way all plates have AA. . . A ¹ A * A ² B the same peripheral speed.

The two needles LL receive the threads of the bobbins of the outermost plates A * A ² and of those adjacent to them, which prevents the edges of the ribbon from becoming entangled in one another.

I have assigned a straight lever M ^{1 to} the usual AfAi clubs of the machine, which feeds the threads of the clapper of the plates A ¹ and B to the funnel N. The threads of these clapper form "the central rib of the ribbon.

The lever M ¹ is connected to one of the clubs M by the lever 0, so that it is set into action by the movement of this club. The rackets MM are moved by the levers Q., which are connected to the eccentric P, from the transmission organs of the machine.

All threads of the clapper C ¹ C ² ... C ⁷⁶ unite in the hopper N, which is arranged at the extremity of the guide piece R, Fig. 7 and 8. The track R can be arbitrarily on the fixed part of the machine at the rear rail S be moved in order to be able to set the hopper JV exactly in the center of the machine. The piece JR also carries two small vertical pins r r, which are quite close to each other, between which the tape passes in order to be folded thereby, and the small roller s over which the folded tape is then passed.

The folded tape then goes over the stepped pulley T, FIGS. 3 and 7, and is finally wound onto the reel U. The stepped disk T receives its movement from the helical wheel ^ and the worm X, Fig. 7 and 8, which sits on the vertical shaft V , which in turn is set in rotation again by the movement organs of the machine. The reel U is moved by the shaft of the stepped pulley T.

If you want to braid the tape Y more or less tightly, you let the same go over a disc of larger or smaller diameter, giving the tape a

greater or lesser speed is granted.

The impellers 5 lead the clapper C ¹ C ² ... C ⁷⁶ from the various plates AA ... Ä * Ä * A ¹ B to the adjacent plates in a known manner.
