An operating rod 21 of a push-pull mechanism 20 is fixed to 19. The first guide rod 18 is movable in the front-rear direction along the longitudinal direction of the band-shaped material V loaded on the material table A, and the movable body 19 is moved by retracting the operating rod 21 of the push-pull mechanism 20. It is adapted to be moved in the front-rear direction between the sewing section M and the band-shaped cloth stacking section X. The movable body 19 is provided with a shaft body 23 which is rotationally driven within a range of 90 degrees by a rotary drive means 22 such as a rotary cylinder. As shown in FIGS. 5 to 10, one end of an arm-shaped frame body 24 is fixed to the shaft body 23, and the frame body 24 is rotated between the standing posture and the lying posture by the rotation driving means 22. It is supposed to be done. Frame
The rotation driving means 25 is provided at the other end of 24. Further, while the shaft body 23 is oriented in a direction orthogonal to the longitudinal direction of the strip-shaped fabric V loaded on the fabric base A, the rotation axis of the rotation driving means 25 is orthogonal to the shaft body 23. It is in the direction to do. The fixed teeth 27a of the chuck 27 are fixed to the rotary shaft 26 of the rotary drive means 25.

As shown in FIG. 8, the rotary drive means 25 has two wheels 28 and 29 fixed to a rotary shaft 26. The wheels 28 and 29 are provided with a torque applying means 30 such as an air cylinder and a spring. The urging means 31 is specially connected to the constant urging means 31, and rotational means of opposite directions are applied to the respective wheel bodies 28, 29 by these means 30, 31. Also, the lever 32 is attached to the rotary shaft 26.
Is provided, and the lever 32 corresponds to stoppers 33a and 33b arranged at two positions displaced by 180 degrees. Therefore, when the rotational force imparting means 30 is pulled in and the rotating shaft 26 together with the wheel body 28 always rotates counterclockwise, for example, against the force of the biasing means 31, the lever 32 hits the stopper 33b to cause chucking. The rotation range of 27 is regulated, and conversely, the rotation force applying means 30 is set to the free state and the rotation axis
When the force of the urging means 31 always rotates the 26 in the clockwise direction, for example, the lever 32 contacts the stopper 33a to restrict the rotation range of the chuck 27. Then, the rotation range of the chuck 27 at that time is 180 degrees.

The chuck 27 includes the fixed teeth 27a and the movable teeth 27b facing the fixed teeth 27a.
And the movable teeth 27b have push and pull means 34 such as an air cylinder.

The operation of advancing to the above is performed, and the advancing operation at this time pulls out the strip-shaped cloth V ₁ from the strip-shaped cloth stacking section X. Then, when the delivery mechanism C moves to the sewing portion M, the chuck 27 is opened, and the tip end of the belt-shaped material V ₁ held by the chuck 27 is dropped from the chuck 27 and is shown by a virtual line in FIG. It is delivered to the sewing section M as shown. At this time, when the preceding band-shaped cloth V ₂ is present in the sewn portion M, the leading end of the belt-shaped cloth V ₁ overlaps the end of the band-shaped cloth V ₂ .
Incidentally, at the time when the leading end portion of the band-shaped cloth V ₁ is the passed to the sewn portion M, the end of the band-shaped cloth V ₁ was remains in the strip material stacking portion X, strip cloth V ₁ was a sewn portion M strip Dough loading section X
It will be in a state of being stretched between.

Here, when the front and back of each strip-shaped fabric are alternately reversed, as in the case where a large number of strip-shaped fabrics V loaded on the fabric base A are reversed in the middle, the strip-shaped top layer is formed in the above-described manner. Cloth
When V ₁ is pulled out from the belt-shaped material stacking section X and delivered to the sewing section M one after another, the belt-shaped material V ₁ delivered to the sewing section M one after another
The front and back of each will be in the opposite direction. Therefore, in the case where the strip-shaped cloth V that has been stretched in the middle is loaded on the cloth table A,
In the middle of the operation of advancing the entire delivery mechanism C from the belt-shaped material stacking section X to the sewing section M, every other sheet, the chuck 27 is rotated 180 degrees by the rotation driving means 25 as shown in FIG. By doing this, when the strip-shaped cloth V ₁ is twisted in the inverted state and the tip end of the strip-shaped cloth V ₁ is transferred to the sewing portion M, the front and back of the preceding strip-shaped cloth V _{2 and} the front and back of the succeeding strip-shaped cloth V ₁ are in the same direction. become. In this case, by simply rotating the chuck 27 by 180 degrees, the band-shaped material V ₁ is twisted in the inverted state, but the twisted shape is likely to be distorted,
If the band-shaped material V ₁ is twisted as described above, the delivery to the sewn portion M is likely to be hindered. In order to prevent such a situation, after the belt-shaped material V ₁ is twisted in the inverted state by the rotation of the chuck 27, the push / pull mechanism 20 is pushed / pulled only a few strokes in a small stroke to front and rear of the delivery mechanism C. You should repeat the process. By doing so, the distorted twisted shape of the belt-shaped material V ₁ is eliminated to obtain an appropriate twisted shape, and the delivery to the sewing portion M is performed without any trouble.
