    At the same time, the central corners of the copier sewing control areas are 3.7511 °, 2Q and the semiautomatic device has a means for adjusting the relative position of the mounting pin and tab, having an emphasis and moktiro placed on the motor guide of the fabric; bath on the foot with the possibility of contact with the stop screw 25. 39 In FIG. 1 shows the kinematic scheme of the alina; in fig. 2 - a copier with a needle movement control track; see 3 is the same in the fabric control track of FIG. 4 shows the device for guiding the fabric in FIG. 5 - product, longitudinal section. The machine consists of a needle mechanism having a needle bar frame, the main shaft 2 of a crank drive 3. The main shaft 2 is connected to a drive (not shown) by means of a ROUND or wedge-shaped belt. The needle bar frame 1 has the ability to rotate around the trunnion 4. The frame 1 oscillations, the driver's needle in a plane perpendicular to the shaft 2, is controlled by an adjustable lever mechanism 5 using a copier 6. The control is performed via the control eccentric track 7 (Fig. 1 dashed line ). The movement of the setting plate 8 in the direction perpendicular to the rolling plane of the needle bar frame 1 is also controlled by the cam 6. The control is carried out by track 9 on the cam 6. The plate 8 is connected with track 9 of the copier 6 by means of the adjustable mechanism 10 The copier 6's lanyards consist of adjacent to each other arc sections 11 and 12 for sewing buttons, sections 13 and 14 for fixing stitches, from sections 15 and 16 for sewing, and from sections 17 and .18 for winding the legs ny govitsy. The control portions 11 or 12 for sewing on buttons have external or internal small portions 19 or 18 and 20 or 21. The radius of curvature of section 15 for controlling sewing is greater than the radius of curvature of external small section 19, which is controlled by sewing on buttons. It is also possible to decide that the radius of curvature of section 15 will be less than the radius of curvature of the inner small section 20 for sewing buttons. However, in this case, the radius of curvature of the control section 16 for sewing is chosen equal to the radius of curvature of the outer small section 18 of the main section 12 for sewing buttons. The radius of curvature of section 16 can be chosen to be equal to the radius of curvature of the inner small section 21 of the main section 12 that sews buttons on the main section 12. The main shaft 2 drives the control disk through the worm 22 and the worm gear 23. A roller 24 is located on the mounting plate 8 for turning the buttons. The roller 24 is moved together with the plate 8 and at the same time has the ability to rotate around an axis perpendicular to the rolling plane of the needle bar frame 1. On the outer end surface of the copier 6, a track 25 (dashed lines) is made into which the roller 26 of the single-arm lever 27 enters. By the controlled track 25, the movement of the one-arm lever 27 through the connecting rod 28 and the toothed rack 29 is transmitted to the gear 30 fixed on the roller 24, turning the buttons. The roller 24 with its end facing the needle is in a known manner connected to the holder 31 buttons. Thus, it is possible to change the distance between the garment and the button, as well as the leg length. The machine is also equipped with: a known device for controlling the cut, the thread and its drawing. A garment blank (not shown) presses against the plate 8 in the direction of alternating movement by the well-known lever 12, which has a fixed axis, but has the ability to inapHHpHoro rotation on the axis parallel to the rolling plane of the needle bar frame 1. The lever 32 is pressed against the sewing workpiece with a roller 33 loaded by the force of the compression spring 34, and after sewing the buttons, this lever can be lifted by the lever 35. The compression spring 36 contributes to lifting the lever. The lever 35 is activated by a starting pedal (not shown). A cam 37 is rigidly fixed on the main shaft 2, which by means of a two-arm lever 38 and a lever 40 provided with 39 actuates the blade 41. On the side surface of the cam 37 there is a control groove 42 in which the roller 39 periodically enters. The roller enters the groove in If the locking lever 43, located on the inner face of the copier 6, is lifted by the cam 44 by means of the lever 45 and against the force of the spring 46. As a result, the lever 40 under the action of another spring 47 enters the groove 42 of the cam 37. The main shaft 2. a pair of bevel gears 48 and 49 and the mechanism 50 for changing the angular speed drives. movement and looper lever 51. On the pin 8, the guide tab 52 is mounted to rotate relative to the hinge 53. The guide tab, when aligned with the part 54, abuts the set screw 55 in the fixedly mounted on the plate 8 stop 56. Thus, the position of the tab 52 with respect to the plate 34, it can be adjusted by a set screw 55. The foot 52 and the part 54 have a coincidence of notches 57, respectively 59 and 60. The notches 58 and 60 in this case are deeper than the notches 57 and 59. The sewing machine works as follows. A buttoned garment is placed on the tab 52. The foot 52 rotates clockwise until the set screw 55 stops against the abutment 56. Thus, the sewing stock is on the part 54. At the same time as the starting part is tensioned, the clamping lever 32 is lowered on the workpiece. the pedal and holder 31 buttons are rotated to a horizontal position. Then, as a result of the oscillation of the frame of the needle holder, the first pair of button hole is sewn sewn. . Button sewing operations essentially coincide with known technical solutions. But then two fixing punctures are made, and the lower layer of material is also sewn. However, the latter process contains the essence of the invention. The first locking puncture or stitch coincides with the right side stitching stitches turned in a vertical plane, buttons (Fig. 5, position 61). But the second fixing puncture (Fig. 5) due to the advancement of the material holding plate 8 coincides with the left-side punctures or stitches of sewing the buttons (position 62). After that, when the nail piercing 63 is applied, the material holding plate 8 remains in place, and the frame 1 provided with a needle moves down through section 15 of track 7 of copier 6 to control the piercing. By this puncture or stitch, the machine also securely holds the lower layer of material without any wrinkling. Upon subsequent piercing of the button holder stitching position (position 64), the needle is deflected to the middle, while the material holding plate moves backward due to movement of the control disk portion 14. Then there is the second sewing of button loops in the manner described above. With a smaller number of punctures, button loops are overlaid in the same place, and with a larger number of punctures and / or an elongated holder, buttons are sewn around with a bias. Thus, a third puncture is used for the piercing, since the thread does not slip out of the needle's eye, but is still free, so the bottom layer of material can be fixed without forming the folds. After the trim of the button holder has been completed, the lever 32, which presses the material down, is raised. Then, the finished work piece is removed from the Collating Guide Material, after which, when a new work piece supplied with buttons is inserted, the workflow cycle is repeated. According to the proposed invention, it is possible to attach high quality buttons and perfect appearance to buttons. Claim 1. Sewing semiautomatic device for sewing buttons, containing a platform with a motor guide fabric, having a mounting plate rigidly attached to it and placed above the last hingedly on the guide tab, and a control copier having arc-shaped control sections connected to the needle movement mechanism stitching buttons, areas for controlling the implementation of locking stitches and areas for controlling the winding of the thread leg, located on the paths for controlling the movement of the needle and the motor of the fabric, This is due to the fact that, in order to improve the quality of sewing on buttons, on both tracks of the copier between the locking stitch control sections and the winding control sections of the thread leg are made along the arcuate sewing control section, each of which has the shape of an arc, while the arc radius of the sewing control section, placed on the needle movement control path, larger than the arc radius of the button sewing control section, and the arc radius of the sewing control section placed on the motor control track m of fabric, is equal to the radius of the arc of one of the control areas by sewing buttons.
