No. 5,156,103) describes a buttonhole slitting machine, in particular an eye-type buttonhole sewing machine comprising a 1[deg.] substrate, a top arm, and a bracket connecting the substrate and the top arm . It also includes a needle bar that is drivable up and down by a main drive motor that has a needle and is supported in the arm; a sewing clip that holds the sewing material. A hooking device for a looper thread is disposed in the substrate. There is a wire arrangement which feeds the loop line to the hook line device along a feed stroke by a line puller disposed at the loop feed stroke. The pull-out includes a suction device that cooperates with a vacuum generator for taking-up of the loop end between the two buttonhole sewing processes. A disadvantage of this known device is that the loop wire can only be pulled out for a very short length. 20 Duerkopp Adler AG brochure "Service Guide 578" No. 0791587037, issued March, 1998, describes an electric moving wire drawing device for a round buttonhole sewing machine, by which the loop wire is pulled from a bobbin . A pivotable rod is provided, the end of which has an eyelet that guides the loop. The rod is pivoted by a pneumatically actuated piston-cylinder drive 1294933 device whose operating speed can be adjusted by a throttle valve. The pulled loops are exposed in an uncontrolled state, which may cause self-tangling, which poses a risk of sewing failure. In order to pull the loop line out of the desired and desired length, the rod must have a substantial pivot angle. 5 If the rod must be pivoted at a relatively wide angle, the structure of the pneumatically actuated piston-cylinder drive that operates the rod requires a corresponding size. On the one hand, the rod must be easily accessible for the threading of the loop line; on the other hand, it must be encapsulated by a protective device to prevent any risk of injury. DISCLOSURE OF THE INVENTION 10 SUMMARY OF THE INVENTION An object of the present invention is to provide a buttonhole sewing machine in which a wire drawing device is designed to be trouble-free and has a simple structure. According to the present invention, the above object is achieved by a buttonhole slitting machine for forming a buttonhole seam in a sewing material, the buttonhole slitting machine comprising a 15 substrate, a top arm, and a connecting substrate And a support for the top arm; a needle bar drivingly reciprocally up and down by a main drive motor, the needle bar having a needle and supported in the arm; a sewing clip for holding the sewing material; a hooking device for holding a loop wire on the inner side of the substrate; a wire harness 20 for feeding the loop wire to the hook wire device along the feed stroke, and a wire pull-out device disposed along the feed line of the loop wire, the wire The pull-out device has a plurality of first ribs disposed at a distance from each other along the feed stroke, and has a plurality of second ribs which are disposed apart from each other at a distance and can be fed toward the first rib and Inserted between the first ribs so that the loop line can be pulled out in a tortuous configuration. Since the loop wire is 1294933 zigzag when it is pulled out, the first rib and the second rib are fed toward each other without requiring long-term privacy. If you have a sufficient number of ribs, only a few millimeters (stroke) is required. The loop line can be easily and arbitrarily inserted because the first rib and the second rib can be moved in a straight line between the first rib and the second rib when the first rib and the second rib are removed. 5 A loop wire conductor arrangement in the form of a loop wire conduit reflects a simple embodiment of a loop wire conductor arrangement that is of course interrupted near the rib. According to this embodiment of the invention, a corresponding gimp thread wire arrangement can be placed in the form of a core wrapped fancy, wire conduit in the vicinity of the loop wire conductor device. There are no additional requirements. A first rib, usually fixed in the sewing operation, can be formed on a wall of the bracket, the wall being a foldable cover, ensuring easy accessibility and, in particular, greatly facilitating the looping line and possible Insertion of the core wrapped fancy line. The cover is a guard that protects the operator from the moving parts of the sewing machine. On the other hand, it ensures the simplicity of threading and the excellent accessibility of the wire pull-out device. Further, the cover has a function of closing one of the fitting holes in the bracket and allowing the fitting hole to be brought close to each other. The drawn line is in a closed space and is therefore protected. 20 a second rib that can be fed is formed on a wire pull-out lever pivotally supported in the bracket, the wire pull-out lever being pivotally drivable by a linear drive, and the second rib that can be fed The insertion depth between the inserted first ribs is adjustable, and an adjustment screw is provided between the bracket and the wire pull-out lever. This embodiment achieves a very simple, compact and reliable structure.

I: Embodiment 3 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A circular head buttonhole sewing machine as shown in the drawing includes a base plate 1 in the form of a casing and a top arm 2 which are connected to each other by a bracket 3 so that the sewing machine is usually It has a general shape of a C shape. An arm shaft 4 is supported in the arm 2 and is driven by a belt drive unit 6 by a main drive motor 5 disposed in the bracket 3. A needle bar 7 having a needle 8 that is drivably reciprocable up and down is generally driven by the arm shaft 4. 1294933 10 15 A hooking device rotary support 10 is typically supported for rotation on a support 9 in a base plate 1 which supports a hooking device 11 for guiding a wire. The hooking device rotation support 10 is further provided with a thread cutting device 11a disposed above the hook wire device 11. A tangential device of this type is described in DE 195 31 727 C2 (corresponding to US Pat. No. 5,647,290). A loop wire conduit 12 and a core wrap wire conduit π are introduced from the top of the bracket 3 through the bracket 3 and the substrate 1 to the vicinity of the hook device 11, especially as shown in Fig. 2. A loop wire η is fed to the hooking device 11 through the loop wire conduit 12, and a core-wound fancy wire 15 can be fed through the core-wound fancy wire conduit 13. An upper line/needle line 16 from the top of the arm 2 is typically supplied to the needle 8. Mounted on the substrate 1 is a movable slide table 17 in the form of an x_y slide, on which a seam clamp 18 is mounted, the slit clamp having two support rods 19 on which the clamps 20, 20' are mounted 19, the sewing material 21 is clamped by the splint on the support plate 22 of the women's clothing on the slide table 17. The construction and operation of this type of sewing material clip 18 is described in DE 102 16 809 A. At the rear face 24 of the sewing machine facing away from the operator side 23, the bracket 3 is closed by a cover 可以 which can be opened and closed by a bottom hinge 26 which extends horizontally in the direction of 7. A wire pull-out device 27 is disposed on the cover 25 and the bracket 3, and the loop wire 14 and the possible core-wound fancy wire are sufficiently punctured by the money pull-out before the button-hole hole X is started. The amount. When the cover 25 is closed, the wire drawing device 27 includes a - (four) having a cross-sectional shape of a comb-shaped structure. It also includes a feedable rib 29 that can be inserted into the rib 28' such that a tortuous line pulls out the channel buckle between and around the ribs 28, 29, such as a width of 20 1294933 degrees a, and thus the entire length of the channel can be adjusted by the feed amplitude of the ribs 29. The possibility of feeding is accomplished by a rib 29 mounted on the first lever arm 31 of a double-arm line pull-out lever 32, which is disposed in the bracket 3 and can be coupled to an axis disposed in the y-direction 33 pivots. The shaft 33 is located below the first lever arm 31. A linear actuating device 35 in the form of a pneumatically actuated piston-cylinder drive acts on the lower arm 34 of the gantry 32, which extends downwardly from the vehicle 33. The cylinder 36 of the drive unit 35 is fixedly mounted on the second lever arm μ to open the opening of the air hose 37 into the cylinder 36. The piston 38, which can be moved in the cylinder 36, is itself supported on a rear wall 39 of the bracket 3. Compressed air is introduced into cylinder 36 via officer 37 from a source of gas not shown at 10 through an electromagnetically actuated valve 40 in the form of a 3/2-way directional control valve. Through the central control system of the sewing machine "trigger valve 40. An adjusting screw 42 is arranged on the rear wall 39 above the shaft 33. When the driving device 35 is actuated by compressed air, the first lever 15 arm 31 is set by the adjusting screw. The range of pivoting toward the cover 25. In other words, the adjusting screw _ = adjusts the depth at which the feedable ribs 29 can be inserted between the ribs 28, which determines the width a of the wire pull-out channel 3〇. A preload compression spring 43 is disposed between the shafts 33, by which the first lever arm 31 is pivoted when the driving device is released, so that the rib 29 is disengaged from the dragon. On the inside of the top 4, the cover 25 There are two retaining springs that are resiliently engaged with the ribs 45 from the rear when the cover is closed, the ribs 45 being formed on the inner top of the bracket 3. In the embodiment of the figures f to 5, on the one hand, the cover 25 and the ribs 28 are formed in a single piece, and the other side of the wire pull-out rod 32 and the rib 29 form a single piece of I294933, both of which are made, for example, of a hard elastic plastic material. The ribs 28 of the cover 25 pass along 2 The directionally extending side plates 46 are connected to each other. The direction of the wire pull-out lever 32 extends beyond the rib 28. In an alternative embodiment according to Figures 6 and 7, each of the feedable ribs 29, i.e., each of the ribs of the wire pull-out lever 32 is at its highest The point has a hardened steel pin 47 which serves as a wear protector which is held at its two ends in two retaining ribs 48 which define ribs 29 at their ends and which are in turn with the ribs 29 'The same way and the wire pull-out lever 32 are integrally formed. There is a free cutting/punching portion 4 9 between the retaining ribs 48 and the respective associated ribs 2 9, which help to make the ribs 48 Elastic flexibility is obtained, thereby making it possible to insert the steel pins 47. Likewise, the ribs 28 can be provided with a hardened steel pin of this type along their highest point as an anti-wear protection device. As shown in Figures 8 and 9 In conjunction with Fig. 3, the loop wire 14 and possibly the core wrap wire 15 are drawn as follows: The 15 wires 14, 15 are located in the conduits 12, 13 interrupted near the wire pull-out device 27. When the 25 is opened, the loop wire 14 and possibly the core wrap wire 15 have been inserted into the conduits 12, 13. When the cover 25 is closed and hit When the device 27, that is, the wire pull-out lever 32 is pivoted rearward, the loop wire 12 and the core-wound fancy wire 13 are located in front of the rib 28 and are smooth and straight, as shown in Fig. 8. Adjusting the correspondence of the 20 screw 42 The adjustment determines that the ribs 29 or 29 will move with the width a into the depth between the ribs 28 when the device 27 is closed. To pull the wire out, the valve 4 is briefly triggered by the control system 41 to cause the wire pull-out lever 32 to rest from it. The position is pivoted to the operative position. The ribs 29 and 29 that can be fed are moved between the ribs 28 to pull the wire. Figure 9 shows the loop line 1294933 that is bent into the device 27 without being caught in the channel 30. And possible core-wound fancy 丨5. When the wire take-up device 27 is opened by the pressure release of the drive device 35, a segment of the loop line 14 substantially corresponding to the total number of ribs 28 and 29 or 29' multiplied by the width a and possibly a tangled core wrapped flower can be obtained. Line 15. The wire has a pull-out length of 80-100 mm. After the 5-wire pull-out device 27 is applied, the loop wire 14 and possibly the core-wound fancy wire 15 will be held in friction by the ribs 28 and the side plates 46; it stays in its defined line position.
