2. Description of the Related Art Clothes for clothes and Japanese clothes are supplied as a roll of a very long raw material, which is cut into a predetermined length and then sewn into various kinds of predetermined shapes. After the process, it is marketed as desired clothes. For example, in the case of suit cloth, the fabric worn by Suit 1 is less than 2 meters long and about 1 meter wide. Therefore, it is necessary to tear off the raw fabric every 2 meters or less. In the conventional tearing, after forming a notch in the tearing start position with scissors or the like in the tearing direction, the running portion of the dough tearing member is brought into contact with the notch and the running portion is run in the tearing direction. Is being torn apart.

[0003]

[Problems to be Solved] However, in this tearing method, after forming a notch, the running portion of the material tearing member is brought into contact with the notch, which is time-consuming, and the tearing at the tearing end position is also performed as described above. Since it is performed by the running part, the fabric that is torn at the tearing end position in the running direction of the running part (the yarn of the fabric in the same direction as this is hereinafter referred to as the weft, and the yarn of the fabric in the direction perpendicular to this is called the warp yarn) The broken end of the warp yarn is pulled out from the inside of the fabric to cause stringing, which not only deteriorates the appearance but also causes serious defects such as fraying of the fabric.

[0004]

OBJECTS OF THE INVENTION The object of the present invention is to solve the above-mentioned drawbacks of the prior art, and to enable easy operation at the cutting start position and elimination of stringing of the cut cloth at the end position when cutting the cloth.

SUMMARY OF THE INVENTION The present invention includes an upper blade and a lower blade above a material to be cut, at least one of which can be moved up and down, and a material severing member having substantially the same height as the material. After contacting the upper blade and the lower blade of the running member at the cutting start position of the dough to form a slit for cutting the dough, releasing the contact between the upper blade and the lower blade and cutting the dough into the slit. The cutting member is contacted and run in the breaking direction to break the dough, and after stopping the running of the dough breaking member before the cutting end position, the upper blade and the lower blade are contacted again and left. The present invention also provides a device for cutting the dough, which is characterized in that the dough is cut.

Hereinafter, the present invention will be described in detail. In the method of the present invention, a pair of upper and lower blades is used to form a cut at the start of cutting and to cut the dough at the end of cutting, and the breaking of the dough during that time is not the cutting by the blade but the cutting by the dough cutting member. Perform by disconnection. In this specification, the cutting of the dough by the blade is referred to as cutting, the cutting of the dough by the dough cutting member is referred to as cutting, and both are referred to as cutting.

The device of the present invention has a pair of blades located above and below the material to be cut and has a material breaking member at a height substantially equal to the material. At least one of the pair of upper and lower blades can be moved up and down, so that the blades can be brought into contact with each other to cut the cloth as required.
The material tearing member itself may be the same as that of the prior art, and is made of, for example, a disc-shaped member. Of the upper and lower blades, the one that can be raised and lowered is preferably the upper blade, which is performed by an air cylinder or a hydraulic cylinder.

The notch is formed by bringing the upper blade and the lower blade into contact with each other and cutting, and the length of the notch is set to be long enough for the subsequent material tearing member to start tearing by running. The place where the breaking is stopped and the upper and lower blades are brought into contact with each other is preferably immediately before the ending position of the cutting, and a slight amount of unbroken dough may remain. After that, the upper and lower blades are brought into contact with each other again, and the remaining portion is cut by the blades so that threading does not occur and the cutting of the cloth is completed. Next, a procedure for cutting the cloth using this cloth cutting device will be described with reference to FIG. 1A to 1D are schematic plan views illustrating an example of how to carry out the method for cutting a fabric according to the present invention.
