[Action]
In the present invention, it is particularly effective in the case of a knitted fabric or the like in which the cloth to be raised or shaved is thin and easily stretched. That is, when raising a cloth, a force exceeding the pulling force of single fibers constituting the yarn must be applied to the cloth. In the case of a conventional raising machine, the cloth conveyed by a plurality of rotating rolls is placed between them. If the rubbing roll rubs, the tension is applied to the cloth, and the cloth roll itself is removed from the friction surface of the raising roll. May occur. In the continuous raising / shearing apparatus of the present invention, the cloth is fixed to an endless belt as a carrier to be conveyed, so that no extra tension is applied to the cloth, and the cloth can be raised without causing elongation or slippage. Moreover, since the distance between the raising roll and the cloth is always constant, it is possible to prevent the cloth from coming off from the friction surface of the raising roll and causing uneven raising.
[0015]
Also, in the conventional hairbrusher, similarly to the above brush raising machine, when the cloth conveyed by a plurality of rotating rolls is sheared by a rotary blade and an underknife near the bed between the rolls, the cloth becomes uneven due to the tension. As a result of stretching and thickness variation, lateral unevenness occurs on the surface of the cloth after shaving. In this respect, in the continuous raising / shearing device of the present invention, the cloth is fixed to an endless belt that is a carrier to be conveyed. It is held in the gap and finished to a uniform surface.
[0016]
Next, in response to a command from the controller, the cutting head operates in the direction of the three orthogonal axes of X, Y, and Z in conjunction with the driving of the endless belt and the raising roll, and the cutter unit is rotatably supported by the cutting head. The shaving is performed according to the pattern pattern stored in the storage device.
[0017]
Furthermore, since a plurality of types of cutter parts attached to the cutting head can be selected and used, a cutter part suitable for the pattern pattern is stored in the storage device in advance, and the cutter part is selected and used appropriately according to the pattern pattern. It is possible to perform efficient shaving. In addition, by arranging a pair of the shaving devices in the left-right direction of the belt, the right and left cloths can be simultaneously shaved separately, and when the raising capacity exceeds the shaving ability and there is a surplus capacity, the both raising apparatuses are operated to increase production efficiency. Can improve.
[0018]
The endless belt needs to fix the cloth against the pulling force of the single fiber during the operation of raising or shaving, and the glue serves as a temporary fixing. Usually, raising is performed between a flat cloth fixed to the belt and a raising roll. In the present invention according to claim 4, a back-up is provided on the back side of the endless belt at a position corresponding to the raising roll. The roll is pressed to protrude the contact portion of the endless belt to the surface, and the fabric is raised between the protruding portion and the raising roll, so that the fabric is raised in a state closer to a linear contact with the raising roll. The pulling force of the single fiber per unit area acts greatly, and the raising effect is increased accordingly.

Depending on the shape to be shaved, for example, the cylindrical rotary blade of FIG. 3A, the V-shaped cutter of FIG. 3B, the (c) square cutter, etc. are mounted on the cutting head 11 according to the shape to be shaved. Next, the arm 13 moves the cutter part 12 to the shaving start position by the moving device, pierces the cutter part to a predetermined depth of the raised part, and starts shaving by operating the cutter part.
[0027]
Simultaneously with the start of shaving, the shavings waste suction / discharge device operates to continuously eject the shavings from the suction port 19 to the outside. In this way, the cutter unit 12 starts shaving and moves along a predetermined shape that forms a pattern. However, since the cloth 4 always moves as the belt travels, the amount of movement of this belt is the same. The controller calculates the shape of the pattern after subtracting the length from the length of the stored pattern shape in the X-axis direction and moves the cutter unit 12 along the pattern shape. Further, it is necessary to move the front surface of the cutter unit 12 so as to face the traveling direction, and the direction control of the cutter unit is performed by a command from the controller based on the pattern program. In the apparatus in which the shaving device is arranged facing the belt in the left-right direction, the left and right sides of the cloth can be separately shaved by the left and right shaving devices in accordance with commands from the controller.
