る。2. Description of the Related Art In a process of processing a raw cloth such as scouring or dyeing, the raw cloth does not always proceed in a state of being continuously spread in the width direction. In general, a raw cloth made of natural materials or rayon expands in the processing liquid, and as a result, the raw cloth is likely to fold and wrinkle in the mangle process. Since it is in a crooked state, it will be twisted and wrinkled. A screw roll for spreading a long cloth in the width direction is usually formed by continuously projecting a convex member on the peripheral surface of a cylindrical roll in order to prevent extreme bending force from being applied to the cloth. In addition, a so-called screw roll that is provided in a spiral shape clockwise and counterclockwise from the center of the roll to the left and right is frequently used. Also, if the friction between the raw cloth and the screw roll is not large enough, the spreading action cannot be sufficiently exhibited, so that the friction is increased by blowing air on the screw roll surface or forming the protrusions with brushes. ing. Generally, the peripheral speed of the screw roll is approximately three times faster than the speed of the raw cloth,
The rotation direction is set to a direction that promotes the traveling direction of the raw cloth, that is, a forward direction, but may be set to a reverse direction depending on the type of the raw cloth and processing conditions. However, there is also a problem that in a state where the cloth is partially folded, the cloth is not sufficiently spread by a single pass of the screw roll, and the screw roll must be passed many times. Hereinafter, the roll of the present invention will be described as a spreading roll to distinguish the conventional screw roll from the roll of the present invention.

A spreading roll is provided in a continuous and / or intermittent state in a direction oblique to the rotation axis direction, and a function of flapping a raw cloth by rotating the spreading roll is added.

る。Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a spreading roll 1 of the present invention. A shaft 3 for supporting both ends of the roll 2 is provided through the roll 2 so as to be rotatable at a predetermined speed by a motor (not shown). A belt-shaped convex member 4 having a height of 10 mm and a width of 3 mm is fixed to the peripheral surface of the roll 2 by welding rightward and leftward from the center of the roll. The convex member 4 is formed in advance of a steel strip having a predetermined height and width into a spiral shape by bending, and is fitted to a roll to weld a contact portion thereof. FIG. 2 is an enlarged view of a portion surrounded by a broken line shown in FIG. In the present example, the convex member 4 is cut off so that a part of the outer peripheral surface thereof comes into contact with the peripheral surface of the roll 2, and is provided as a surface 5 at a position shifted by 120 degrees in the circumferential direction. FIG. 3 shows a side view of this state as viewed from the shaft 3 side. The raw cloth 6 passes over the spreading roll in the direction of arrow B by another transport means,
The raw fabric 6 is brought into contact with the spreading roll 1 by the guide rolls 7 and 7-1 and advances. In this state, when the spreading roll 1 is rotated in the direction of arrow A at a peripheral speed of about three times the conveying speed of the raw cloth 6, the raw cloth 6 repeatedly moves up and down between positions indicated by broken lines, The spirally provided convex member 4 acts to spread the raw cloth. Therefore, the folded portion can be easily spread by the vibration and the ironing action.

る。In this embodiment, the convex member 4 is cut off at the tangent to the outer circumferential circle of the roll 2 to form the surface 5, but the length from the axis of the roll to the surface 5 is L1, the convex member 4 When the length reaching the outer edge portion is L2, at least one portion having different lengths of L1 and L2 may be formed, and the surface 5 does not necessarily need to be formed by the tangent line of the outer circumference of the roll. However, since the spreading roll is rotated, it is preferable to provide two or more locations in order to prevent the weight from being biased with respect to the rotating shaft.

ことでも拡布を行うこともできる。In the above-described example, the arrangement of the convex members 4 is helically arranged continuously. However, as shown in FIG. 4, the convex members 4 are divided to form the convex members 4-1. Spreading can also be performed by constructing, moving in parallel, and providing the same as the convex members 4-2 and 4-3.

ことができる。FIG. 5 shows a side view as seen from the shaft 3 as an example in which the length of the roll from the rotation axis is different. The convex member constitutes the spreading roll 1-1 with an elliptical basic shape. The liners 8 and 8-1 are fixed at target positions with respect to the axis of the roll 2, and the convex members 9 are spirally wound left and right from the center of the roll to the outside and fixed to the roll. Is what you do. Also in this case, if the length from the rotation axis of the roll to the outer peripheral edge of the convex member 4 is L3, L4,
There are two short length L3s and two long L4s. Similar to the above-described embodiment, the spreading roll 1-1 can be spread while applying vibration to the raw cloth by rotating the spreading roll 1-1.

工に用いることでその効果が十分に発揮できる。According to the spreading roll of the present invention, which has a function of flapping the raw cloth, wrinkles generated in the raw cloth in processing steps such as scouring and dyeing can be applied to the single spreading roll of the raw cloth. It is possible to sufficiently spread and spread the cloth only by passing through, and to spread the cloth effectively even in a place where there is little room for installation of the processing device. In addition, even if the raw cloth is partially folded, the cloth can be sufficiently spread, and the effect can be sufficiently exerted particularly when used for processing a thick woven cloth.
