This cloth material M was sewn into a tubular shape,
This is what is called a tube counter.

Here, a specific method of spreading will be described. First, as shown in FIG. 6A, the reversing machine S is arranged at an initial position, and the end of the cloth M is set at a predetermined position. When the reversing machine S is at the initial position, the cutting unit 80 is also at the initial position, that is, at the left end of the rail frame 70 in FIG. Further, the pair of feed rollers 28, 3 between the feed rollers 28, 30 of the main body device A.
A tentering frame W as shown in FIG. 1 is placed on the top of the tube 0, and the tentering frame W is passed through the opposite side of the tube so that no wrinkle is generated in the opposite side of the tube. In addition, the following operation of the spreading machine S is controlled by a control unit (not shown).

First, the spreading machine S draws out the cloth material M while moving on the outward path on the rails 40 and 42 in the direction of the arrow in FIG. 6A (FIG. 7, S10). The movement of the reversing machine S is performed by controlling the traveling mechanism section by the control section.
Delivery of the cloth material M is performed by the belt conveyor 24 and the feed rollers 28 and 30. That is, the control section controls the motors for driving the belt conveyor 24 and the feed rollers 28 and 30, and derives the cloth M. Then, when it comes to the end point position shown in FIG. 6B, the spreading machine S stops moving and also stops drawing out the cloth material M (FIG. 7, S11). That is, the control unit stops driving the traveling mechanism unit and the motor.

At the same time (or immediately thereafter) when the movement of the spreading machine S is stopped and the dispensing of the cloth M is stopped (or immediately thereafter).
And the cutting unit 80 travels while rotating the round blade 124 while holding down the cloth material M (FIG. 7, S11). Then, the cloth material M becomes the guide 13
4 to be cut between the round blade 124 and the tip 136 (FIG. 7, S12). When the cutting unit 80 comes to the end position, that is, the right end of the rail frame 70 in the case of FIG.
Contacts a limit switch (not shown), whereby the cutting unit 80 stops. The rotation of the round blade 124 also stops (FIG. 7, S13).

Next, when the cutting unit 80 stops running, the reversing machine S moves in the opposite direction. That is, it moves on the return route (S13). On this return path, no extension is performed because the extension is in one direction. While the reversing machine S moves on the return path, the cutting unit 80 returns to the original initial position. The reversing machine S stops when returning to the initial position (FIG. 7, S1).
4). One rolling operation is performed as described above.

Then, the spreading operation is repeated until the spreading operation is completed (S15 in FIG. 7). That is, the spreading machine S derives the cloth material M while moving on the outward path,
When the end position is reached, the reversing machine S stops moving and also stops drawing out the cloth material M. In the case where the reversing is repeatedly performed, the process of aligning the ends of the cloth material M when the reversing machine S is at the initial position is not necessary. As described above,
According to the reversing machine S of this embodiment, it is possible to automatically perform the one-way spreading without any manual work.

In the above description, it has been described that the cutting unit 80 stops when the limit switch rod 140 contacts a limit switch (not shown) after the cutting unit 80 starts running. Dough M
May be detected, the vehicle travels only in that range, stops at the end of the cloth material M, and then runs backward. Then, work time can be reduced.

When performing reciprocating rolling, the cutting device B may be removed from the main unit A and used.
Further, in the above description, the tube cloth has been described as an example of the cloth material for performing the spreading, but it is not necessary to be the tube cloth. In other words, depending on the cloth, it is necessary to perform one-way spreading. Therefore, for the cloth having such properties, the one-way spreading is automatically performed by the spreading machine S of this embodiment. Can be. In addition, when the cloth material other than the tube is extended, the width frame W (see FIG. 1)
Is removed and the interval between the feed roller 28 and the feed roller 30 is slightly widened.
