On figs 16 the one-line seam executed by small-sized sewing machine is shown.

The small-sized sewing machine will consist of the mechanism игловодителя, the mechanism петлителя and the mechanism gear рейки (figs 1, 2).

The mechanism игловодителя contains the basis 1 on which it is fixed directing 2, moving along it(her) рейка 3, for example, by means of rollers 4, 5, 6, located with two parties(sides) from directing 2. Thus rollers 4 and 6 can settle down from above, and a roller 5 - from below directing 2, or on the contrary. On рейке 3 by means of the hinge 7 it is established иглодержатель 8 with the bent needle fixed in it(him) 9 with ушком on the end (on figs. It is not shown). The coil with threads can fasten on the basis of 1 (on figs. It is not shown). The lever 10 which is connected by one end to draft of 11 (figs 1,2) of variable length by means of the hinge 12 is attached to an axis of the hinge 7. Other end of draft of 11 variable lengths is connected with рейкой 3 by means of the hinge 13. Рейка 3 by means of the hinge 14 it is connected to draft of 15 variable lengths which is connected to the basis 1 by means of the hinge of 16 (figs 1).

Рейка 3 it can be carried out as two plates between which rollers 4 are established, 5, 6. Axes of the hinge 7 иглодержателя 8, rollers 4, 5, 6 and шарнирных support 13, 14, 16 are parallel among themselves and перпедикулярны to a plane рейки 3 and directing 2 (figs 2).

The device петлителя (figs 1, 2) will consist from motionlessly fixed on the basis of 1 vertical bar 17, the basis 18 петлителя, the rotation executed with an opportunity concerning an axis of a bar 17, draft 19 change of the length fixed motionlessly on a bar 17, a returnable spring 20 which one end is connected to the basis 18 петлителя, and other end – with a bar 18. On the basis of 18 петлителя the drive 21 turns of a hook 22 петлителя is established. The drive 21 can be carried out as screw connection or, for example, шестеренчатой transfers 23, 24 which actuates a hook 22 петлителя.

The axis шестерни 24 is connected to a returnable spring 25 which returns a hook 22 петлителя in a starting position. Draft of 19 variable lengths provides turn of the basis 18 петлителя for capture игольной strings. Draft 19 is motionlessly fixed on a vertical bar 17. The rod of draft 19 contacts to the bottom surface of the basis 18 петлителя, located under a corner to a bar 17. Thus it is formed кулачковый the mechanism providing turn of the basis 18 петлителя around of bar 17 for capture of a string at promotion of a rod of draft 19, and returning in a starting position by a spring 20 at removal of loading from a rod of draft 19.

The mechanism gear рейки will consist from gear рейки 26 and drafts of 27 variable lengths (figs 2).

Drafts 11, 15, 19, 27 variable lengths can be carried out as screw mechanisms, hydrocylinders, pneumocylinders, etc. Actuating of mechanisms игловодителя, gear рейки 26 and петлителя, making the small-sized sewing machine, is possible in manual, and also with the help энергопривода, cooperating with corresponding draft, in a preferable variant of performance – as the electromagnetic relays working on a signal from the switch or control systems (on figs. It is not shown).

The small-sized sewing machine works as follows, carrying out the offered(suggested) way.

The sewing machine is established on the spread layers of a fabric 28 (figs 1, 6, 7). Further manually or by means of 11 variable lengths connected to draft энергопривода, turn иглодержатель 8 concerning an axis of the hinge 7 fixed on рейке 3, and enter the bent needle 9 with вдетой in ушко a thread in connected layers of a fabric almost perpendicularly its(her) surfaces (figs. 6, 7). Then with the help of draft 15 move along directing 2 рейку 3. Thus the corner of an input(entrance) of the bent needle 9 in layers of a fabric, down to an arrangement of the end of a needle 9 on a tangent to a surface on which the fabric lays changes. Simultaneously with it by means of draft of 27 variable lengths gear рейка 26, being shifted, forms складку fabrics 29. Further, by means of draft 11 finish turn иглодержателя 8 around of the hinge 7 up to an output(exit) of a needle 9 of a fabric. Then draft 11, coming back in a starting position, turns иглодержатель 8 in the opposite direction, forming from a thread a loop as the letter "ï" (figs 12).

Further with the help of draft 19 the basis 18 петлителя which, moving around of a bar 17, removes the formed loop from a needle 9 is actuated. After that draft 21 actuates a hook 22 петлителя which, being with a underside of a loop together with носиком 30 петлителя (figs 13), doing(making) turn around of an axis 31 шестерни 24, bends around the party(side) of a loop (figs 14) which leaves a fabric and grasps the second party(side) of a loop (figs 10). Further, removing loading from draft 21 with the help of a returnable spring 25, the hook 22 петлителя moves in the opposite direction together with the seized string and is kept on носике 30 петлителя (figs 11). Further, removing loading of draft 19 with the help of a returnable spring 20, the basis 18 петлителя, coming back in similar position, passes удерживаемую on носике 30 петлителя a string in a loop (figs 14). Further, removing loading from draft 11, the needle 9, coming back in a starting position, tightens(delays) unit (figs. 15).

Simultaneously with reverse motion of a needle 9 the effort to draft 21 moves, thus the hook 22 turns concerning an axis 31, releasing(exempting) удерживаемую a string on носике 30 shuttles. In result on a thread 32 going behind a needle 9, the unit fixing position of a stitch on a surface of a fabric, with formation(education) of the seam shown on fig 16 is tightened(delayed). Further the thread 32 обрезается, or the basis 1 is transferred to the distance equal to a step of a stitch, and the cycle repeats.

The arrangement of mechanisms игловодителя, петлителя and gear рейки on one party(side) of a surface of a fabric allows to execute seams directly on the spread layers of a fabric. In result accuracy of performance of a seam raises, convenience to the approach to connected layers of a fabric is provided and the seam strong enough, nonstop, elastic and easily dismissed is formed.
