2. Description of the Related Art A lace used for women's dresses, blouses, and other underwear is usually made by cutting a desired pattern unit portion from a machine race in which predetermined patterns are continuously applied at appropriate intervals. It is being formed,
Since such a lace or embroidery of hat embroidery has the required pattern three-dimensionally applied to the surface of the fabric, it is not possible to cut accurately with a constant contour if two or more layers are stacked, so it is usually a single pattern. It is cut into individual sheets. However, in addition to manual work such as scissors and roller cutters for this cutting, as a mechanical means, conventionally, it was installed horizontally with the facing surface parallel to the upper die pressure plate that was moved up and down with a predetermined stroke. The desired pattern part of the material is sent to the upper surface of the lower die pressure plate, and the blade part of the blade type is bent and formed along the contour shape corresponding to the required cutting pattern of this material. It is placed so as to match the cutting contour and placed downward, and then the upper die is lowered to push and cut between the upper and lower pressure plates to perform cutting. It should be noted that any one of the upper and lower pressure plates has a cushioning plate such as rubber that acts as a cushion between the pressure plate and the back mounting plate.

[0003]

By the way, since the machine lace and the like are mainly made of yarn and are continuously formed for a long time, they are likely to partially expand or contract, or are affected by temperature, humidity, or other handling. At that time, it is inevitable that the pattern is partially deformed. Further, since the blade die is also formed by bending a thin steel plate having a vertical width of about 10 mm in accordance with the cutting pattern, the blade portion formed on one side of the blade die has a contour to be cut on the pressure plate with the material. Not only does it require considerable skill to place them on the line in exact alignment, but it also makes long-term work difficult.

The present invention addresses such a situation, and a required blade die is mounted on the upper surface of the lower die pressing plate in an attracting manner with the blade portion facing upward, and the material of the blade die is placed on the blade portion of the blade die. When the cutting contours are placed in conformity with each other, the material is placed in a flat state on the blade portion, so that the position of the pattern portion with respect to the blade die can be determined easily, quickly and as accurately as possible. The purpose is to let.

[0005]

According to the present invention, an upper die and a lower die are provided with an upper surface and a lower surface. A material provided with a pattern and a blade die in which a blade portion is formed in accordance with the contour shape of the material to be cut are positioned such that the blade portion of the blade die and the contour shape of the material are in contact with each other, and the upper die Is a die-cutting and cutting device for pressing down a part of the material along the shape of a blade by lowering the lower die, and the lower die is a non-magnetic support plate having a magnet on its upper surface, It is formed with a pressure plate made of a ferromagnetic material that is installed in contact with the support plate, and the blade mold is attached to the pressure plate of the lower mold with the blade portion facing upward and placed on the pressure plate. In the inner and outer spaces of the blade die, the thickness of the blade die is approximately the same as that of the blade die, and the inner and outer surfaces of the blade die are in contact with each other. Characterized in that occupies provided an inner frame and an outer frame made of an elastic plate with.

[0006]

In the cutting machine of the present invention, a blade die formed in a predetermined contour shape is mounted by adsorbing it on a pressure plate provided in a lower die in an upright state with the blade portion of the blade die facing upward. When the inner frame and the outer frame made of the elastic plate are placed in the space inside and outside the blade die on the pressure plate, the blades occupy substantially the same plane as the upper surfaces of the inner and outer frames. is there.

Then, by guiding the required material, which is fed from the side on the inner and outer frames including the blade portion, in a plane, the cut contour line of the race is set in the gap between the inner and outer frames. It is possible to exactly match as a plane state on the exposed blade portion, and then when the lower die is positioned directly below the upper die and the upper die is lowered, the pressure plate of this upper die and the blade portion It is pushed by and the contour portion of the material is cut.

The opposing surfaces of c and 10b are flat and are in contact with each other in parallel with each other.

Reference numeral 13 is a blade die formed by appropriately bending a thin strip-shaped steel sheet having a vertical width of about 10 mm so as to form a required contour shape in a plane, and the blade die has a blade portion 13 'at its rising upper edge. When the blade 13 ′ is directed upward and its lower edge is placed at an arbitrary position on the upper surface of the pressure plate 10 b having the flat shape, the blade 13 ′ is attracted to a predetermined position by the magnetic force of the pressure plate. It is.

The blade die 13 shown in FIG. 3 is formed so as to surround the entire circumference. This is a machine in which appropriate unit patterns are repeatedly shown at regular intervals in the longitudinal direction. It is used to cut a desired contour shape portion from the race (L) so that the blade die is shaped like a U-shaped one side edge (L ') of the race depending on the kind of the pattern shape. It may have an open shape.

Each of the blades 14a and 14b is made of a flexible elastic plate such as urethane foam, and is formed by the blade 12
An inner frame and an outer frame each having a thickness substantially corresponding to the vertical height of the blade mold and formed so as to extend along the inner and outer side surfaces of the blade mold, respectively, in a state where the blade mold 13 is sandwiched therebetween. By placing it on the upper surface of the pressure plate 10b, the machine race (L) can be easily moved to the upper surfaces of the inner frame 14a and the outer frame 14b including the blade-shaped blade portion 13 '.
