Description of the Invention: [Technical Profile of the Invention] The present invention relates to a suture tensioning device equipped with a suture and a tension, and, "/, and a needle for supplying a needle and... In particular, there is a line tension device for the tension of the micro-H# cloth which can be sewed by the thief. [Prior Art] In the case of sewing machine sewing machine, etc., the needle thread of the thread looper, etc., should be used for the needle thread of the supply needle, and the supply tank, and the various clothes dryers including the thread tension tension. ::The majority of the needle thread tensioning device for the needle thread and the tension, the hand: "Bomb: the disc, and the force applied to each of the discs to push each other's force. # (spring, electric cymbal, bar knife electric screw g) And in the following manner, the shackles of the door of the suture tension disc and the Fu Cheng broken are clamped at the time of pulling out, and the action of the needle and the thread retractor is applied to the suture tension disc. The friction force between the clamping faces imparts tension (for example, refer to Patent Document 1). The force of the suture tensioning device of the suture tensioner including the frictional resistance type is applied. By adjusting the pressing force of the suture tension disc; changing the position of the needle thread and the tension, although it can be applied to the tension of the sewing conditions such as the cloth, but the force is reduced. When the state of the slight tension is applied, the tension is pressed by the weak force. The state of the push, due to the position of the needle thread, the vibration during operation, etc., has a problem of being difficult to maintain and maintain tension. A suture tension device is proposed (for example, refer to the patent document, the solution 2098- 9874-PF; Ahddub 5 200928036, this problem can be assigned to a small tension. This suture tension device includes: one of the pair of thread tension discs rotating around the shaft; and adjustment means to adjust the size of these rotational resistance The needle thread is clamped between a pair of suture tension discs, and is wound to the needle after about one turn, and the suture tension disc is pulled out with the action of the needle and the thread retractor. When rotating, the needle thread is given a tension corresponding to the dynamic resistance. ❹ In the suture tensioner having the above structure (rotation resistance type suture tension), the rotation resistance of the suture tension disc can be adjusted in a small area. The needle thread is stably imparted with a small tension, and this tension is imparted, because the needle thread on the upstream side of the quilting thread tensioner itself has a tension, and the green-green + strong self-stitching thread tension disclosed in Patent Document 2 is feasible. Device 'will be on, The needle thread of the main thread tensioner is assigned to the auxiliary tension pair, ^^^, which is placed on the upstream side of the rotation resistance type thread tensioner (main seam tensioner). The secondary thread tensioner and In the patent document, the friction resistance type hand h is applied to the needle thread which is clamped to the thread tensioning device of the pair T, and the frictional resistance is applied to the needle thread between the thread tension discs. As described above, the sub-thread tensioner is used to compensate for the slightest area in the tiny area... It is compensated by the main line tensioner of the rotary resistance type, and can cope with the sewing of thin cloth and soft cloth.

The guide grooves 8a to 8d are inserted into the needle thread Z of the rotating drum 51, and have a supply side from the suture supply source, and the side is long, and the tension port is oriented toward the main suture. The leading side of the mouth 4 goes to the perimeter of ^ in order. Further, in Fig. 2, in order to prevent the drawing from becoming complicated, the symbols 8a to 8d are omitted. The reference numeral 70 of the suture hole and the reference of the guide groove are not attached to the needle thread 2 of the money thread tension ^5, and are pulled out to the lead-out side as the rotary drum 51 rotates. ^ Capture, the needle thread 2 wound around the outer circumference of the rotary cymbal 51 without overlapping, is tensioned on the respective winding loops of each of the turns, and tension is generated by the mutual pulling between the windings. _ m knife is wound around the needle thread 2 of the rotating drum 51, as described above, because the circumference is shortened to the pulling-out side, and the tension on each winding ring is good, and Produces a stable tension. As described above, the sub-thread tensioner 5 serves to supply the main suture tensioner 4 to the needle thread 2 which does not have the tension supplied from the suture supply source. The length of the pre-injury tension is applied to the needle thread 2 by the auxiliary thread tensioner 5, corresponding to the tension generated by the mutual pulling between the winding turns of the rotating drum 51 as shown above, and the minute rotation of the rotating drum 51. The combination of rotational resistance f. Wherein, the rotational resistance of the rotating drum 51 is as described above, because it can be adjusted by operating the adjusting knob 52, so the auxiliary stitching tensioner 5 can be stabilized by 2098-9874-PF/Ahddub 17 200928036 The pre-tension of the force zone can be adjusted. Therefore, under the application of the preliminary tension as described above, the action of the main suture tension #4 described above can be used to securely tighten the needle 6 through the suture in a small force region. The tension of the needle 15 and the thread 2 can be satisfactorily sewn into a thin fabric or a soft fabric including a fabric using microfibers without causing a seam defect as shown in Fig. 4. In addition, in the above embodiment, the number of windings of the needle thread 2 on the outer circumference of the rotating drum 5i is set to 4 mesh', but the plural number is wound under the condition that the width direction is not overlapped. Circle (more than 2 mesh) can be. Further, in the above embodiment, the circumferential length of the needle thread 2 is different, and the suture guide 8 extending in the direction orthogonal to the substrate 50, that is, the widening direction of the rotating drum 5i has a different depth. And forming the guide groove 8a: and engaging the needle thread 2 with the guide grooves, but it can also be realized by other (4), for example, the suture guide 8' which will form the guide grooves 8a to 8d having the equal depths The distance from the outer circumference of the rotary drum 51 is set to be smaller toward the front end side. Therefore, the sewing thread is engaged with the guide groove every time the needle thread 2 is wound, and wound around the rotary drum 51 to achieve the difference in circumference. . Further, in the above embodiment, an application example of the mineral tooth key sewing machine is described, but the present invention is of course not limited to a zigzag chain sewing machine which can be applied to a slit which requires a slight tension.
