Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for adjusting the width of fibers aligned in one direction.

[0002]

2. Description of the Related Art As a method for adjusting the width of a plurality of fibers aligned in one direction, a method of narrowing the pitch of each comb pin constituting an adjusting device or arranging them vertically to the longitudinal direction of the fibers. There is known a method of changing the angle of the comb to be formed (up to 45 ° with respect to the longitudinal direction of the fiber). The obtained unidirectionally aligned fibers are impregnated with a resin varnish and then dried to obtain a prepreg. This prepreg is laminated by shifting the angle of a plurality of fibers at different angles to form a laminated body. The obtained laminate is used as a laminate excellent in mechanical and thermal properties.

[0003]

The method of adjusting the fiber width by narrowing the pitch of each comb pin described above requires a long time to insert the fiber between the pins, and the comb pin 1 Since each book becomes thin and the edge of the pin becomes sharp, it is easy to damage the fiber, and it is impossible to adjust the fiber width widely.

A method of adjusting the fiber width by changing the arrangement angle of the combs arranged perpendicularly to the longitudinal direction of the fibers is a method in which a large number of combs are arranged in a horizontal row. Was limited to 45 ° at maximum, and there was a limit in adjusting the width of the fiber.

The present invention has been made in view of the above circumstances, and an apparatus capable of arbitrarily adjusting the widths of a plurality of fibers aligned in one direction by improving the structure of the comb and the method of attaching the comb. It is intended to provide.

[0006]

In order to achieve the above object, the present invention provides a comb 5 in which a plurality of fibers 1 aligned in one direction are arranged.
In the device for adjusting the fiber width by passing between the pins 6, the comb 5 is arranged on the turntable 4, and the pins 6 of the comb 5 are formed in an elliptical cross section, and the long axis thereof has a plurality of pins. 6 is provided so as to be aligned with the arrangement direction of 6.

[0007]

According to the present invention, the fiber width can be arbitrarily adjusted by changing the arrangement angle of the fiber with respect to the longitudinal direction within the range of 0 ° to nearly ± 90 °, and the cross section of the pin is elliptical. Because of the shape, even if the arrangement angle of the comb is changed in the range of 0 ° to ± 90 °, the fibers can be smoothly passed between the pins without damaging the fibers.

The fiber width adjusting device according to the present invention is a width adjusting device for arbitrarily adjusting the width of fibers aligned in one direction without damaging the fibers. A comb including a plurality of pins is arranged on the turntable, and each pin has an elliptical cross section. The pins are provided so that their long axes are aligned in the direction of arrangement of the plurality of pins.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic perspective view of an adjusting device according to the present invention, and FIG. 2 is a schematic perspective view of a comb. In each figure, a comb 5 is arranged perpendicular to the longitudinal direction of a plurality of fibers 1 aligned in one direction. The comb 5 is detachably set in the groove 8 of the support base 7 with the plurality of pins 6 facing upward, and the support base 7 is arranged on the turntable 4.

As shown in the enlarged view of FIG. 3, each of the pins 6 constituting the comb 5 has an elliptical cross section perpendicular to its axis, and the major axis of this ellipse is a plurality of pins 6, 6. It is provided so as to be aligned with the arrangement direction of.

The fiber 1 moves between the pins 6 of the comb 5 in the direction of FIG. 1, and the transport guide roll 2 is disposed in front of the comb 5 as viewed in the moving direction of the fiber 1, and the front side of the comb 5 is provided. Comb 5
The conveyance guide roll 3 for drawing in is disposed.

In the embodiment of the present invention, the fibers 1 aligned in one direction pass between the elliptical pins 6 forming the comb 5 on the turntable 4 and move to the next step. In this case, the state in which the turntable 4 is vertically arranged with respect to the moving direction of the fiber 1 is set to 0 °, and the state parallel to the fiber 1 is set to 90 °
And

The width of the plurality of fibers 1 is determined by rotating and fixing the turntable 4 on which one comb 5 is installed at an arbitrary angle from 0 ° to ± 90 °. When the arrangement angle of the comb 5 is changed, the relationship between the gap between the pins 6 and the fiber 1 changes as shown in FIG. That is, since the pin 6 is formed into an elliptical shape, the angle of the comb 5 is 90 °.
When the distance is changed to a large value, the difference between the major axis and the minor axis of the elliptical pin 6 can narrow the interval between the pins 6 when viewed in the arrangement direction of the fibers 1.

This can be easily understood by comparing with a normal pin 6a having a perfect circular cross section as shown in FIG. In other words, if the pins 6a have a perfect circular shape, there is almost no gap between the pins when viewed in the moving direction of the fiber 1 only by slightly changing the arrangement angle of the comb 5 with respect to the moving direction of the fiber 1. Moreover,
The width of each fiber 1 cannot be made narrower than the range limited by the diameter of the perfect circular pin 6a itself.
As described above, since the pin 6 according to the present invention has an elliptical shape, the width of the fiber 1 can be smoothly adjusted, and
There is no problem in the outer shape for not damaging the fiber 1.

[0015]

As described above, according to the present invention,
By making the cross-sectional shape of the pins forming the comb elliptical, the width of the fibers aligned in one direction can be adjusted arbitrarily.
Further, according to the present invention, by narrowing the pitch of each pin, it takes time to insert the fiber between the pins, and
By making the pin thin for each book, the problem that the edge of the pin becomes sharp and the fiber is damaged can be eliminated.
