示されている。(Conventional technology) The way the fabric is bent has a great effect on the operability of the sewing process. For example, for soft fabrics, temporary hardening methods are commonly used to improve operability. . In this case, operability is stabilized by measuring the bending stiffness of the dough and constantly curing it to a constant stiffness. If the bending behavior is known not only in the temporary curing process but also in other sewing processes, good products can be made by adopting sewing conditions that correspond to that. In addition to the sewing process, we also evaluate and manage the texture of the fabric.
Measuring the bending stiffness of fabrics is very useful. In particular, when performing automatic sewing, the bending method of the fabric is a bending curvature of 7 to l.
A case with a large bending curvature such as 5cIII-1 was required. On the other hand, with regard to measuring the bending stiffness of fabrics, many measuring devices have been proposed, including devices for measuring the -g coefficient and the like.

゛験機本体に接触して、計測出来ない欠点がある。However, in measurements using these devices, the amount of bending deformation imparted to the fabric is small, with a bending curvature of less than 3 countries - 1, with a ratio of ±2.
5cIR-1 is small, and the fabric is thick (approximately 2.3 songs or more), and the tester's chi-tsuku metal fitting is measuring -1CK: [
゛There is a drawback that measurement cannot be performed due to contact with the main body of the test device.

常に不便であった。This tester measures the bending of the fabric by moving one plate closer to the other plate. -If you want to measure the bending stiffness using the bending curvature, you must set it by moving the mounting position of the motor, which is attached to the top plate, up and down to obtain the pre-calculated value while looking at the scale of the dial gauge. It was extremely inconvenient.

曲げ特性測定装置である。(Means for Solving the Problems) The present invention provides a lower tip of an elevating member that moves up and down at a constant speed (a holding plate is disposed, and a measurement fabric is placed directly connected to a dynamometer at the lower end of the elevating member that is aligned with the presser plate). This is a large deformation bending characteristic measuring device in which a placing plate is arranged, and the elevating member is connected to a motor and also connected to a small combiner for controlling the movable range of the elevating member.

The rotation of the shaft is converted into vertical motion by gears. A flat holding plate 2 is formed at the lower end of the elevating member 1. A measurement fabric mounting plate 3 is formed parallel to the pattern pressing plate 2 and at a lower position corresponding to the pattern pressing plate. The lifting distance of the lifting member 1 is controlled by a potentiometer connected to a small combination controller 11, which detects the position of the presser plate 2.

る。As a method of imparting a large amount of bending deformation to the fabric (for example, the curvature of the maximum surface deformation portion is 7a11 or more), the distance measurement fabric 8 is placed on the measurement fabric placement plate 3 in a bent manner, and By lowering the plate 2, a bending deformation that is 1 more than the deformation amount is applied. Then, the bending force at this time is detected and measured by the force meter 7 ◇ In this case, two plates, that is, the presser plate 2
Even if the distance between the measuring fabric mounting plate 3 and the measuring fabric placement plate 3 is the same, the amount of bending deformation that the fabric undergoes differs depending on the thickness of the fabric placed between them.

９は生地の最大変形時の曲率（、−’）である。Therefore, the relationship between the distance between the two, the thickness of the fabric, and the bending curvature was expressed mathematically, and this was incorporated into the machine and controlled by a small combination. In other words, when the amount of bending deformation that the fabric undergoes is expressed as a curvature, the following relationship holds between this curvature, the thickness of the fabric, and the distance between the two plates: D=2(d+1/l)...・・・・・・・・・・・・・・・
(1) where D is the distance between the two plates (α), d is the thickness of the fabric (,), and 9 is the curvature (, -') at the time of maximum deformation of the fabric.

へ出力出来るものである。In the present invention, the distance (spacing) between the presser plate (upper plate) and the measurement fabric mounting plate (lower plate), the thickness of the fabric to be measured, and the bending curvature to be measured are determined by a small computer built in the measuring device. 1) It is controlled by the relationship of formula. For example, if you want to measure the bending of different fabrics using the same bending curvature, you can input the predetermined curvature, fix it, and input only the thickness of the fabric to be measured, and the thickness will be automatically corrected. , the bending stiffness at a predetermined curvature can be measured. Also, when measuring different curvatures on the same sample,
By identifying the input of the thickness of the fabric and inputting the measurement curvature, the bending behavior at each curvature can be measured. In this way, simply by setting the dials for the thickness of the fabric and the measurement bending curvature, the bending behavior at the desired bending curvature can be measured. The measured values can be output to an X-Y recorder whose axes are the degree of bending applied to the lower plate and the displacement of the upper plate.
