Abstract

PURPOSE:To make a core member light in weight as well as to facilitate handling by employing a bag body made of resinous films in which air is injected as a core member in a method wherein a flexible flat body is winded over the core member in a roll shape and the winded flat body is fastened with binding tapes at places as required thereafter. CONSTITUTION:In a winding method wherein a flexible flat body 1 such as a foot wiping mate, a soft ball and the like is winded over a core member 2 in a roll shape, and the winded flat body 1 is fastened with binding members 3 such as tapes, bands and the like at places as required thereafter, a bag body made of resinous films is employed as a core member 2 wherein the bag body is inflated with air injected. Handling of the flat body 1 winded in a roll shape can be facilitated with the core member 2 made light in weight. And when the flat body 1 is winded or just before winding is started, the bag body can be formed only with air injected, the use of the bag body is thereby advantageous in space for storing the core member 2 as compared with a hard paper core.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention winds a flat body such as a foot-wiping mat or a carpet around a core material, and then tightens the required portions of the wound flat body with a binding material such as a string or band. The present invention relates to a method for winding a flexible flat body.

[0002]

2. Description of the Related Art In a conventional method for winding a flexible flat body, a hard paper core formed by processing cardboard into a cylindrical shape is used as the core material.

[0003]

In the case of this conventional method, since the paper core itself is heavy and the volume of the core material is large, a lot of space is required for storage before the winding work. Moreover, if the flat body wound in a roll has a weak tightening force, the flat body not only shifts to the one end side in the axial direction of the roll in a bamboo shoot shape, but also causes the core material to fall out during handling. .. In order to avoid such a problem, it is necessary to tighten the flat body wound in a roll shape with a strong force, and thus various restrictions are imposed on the selection of the binding material and the tightening device.

The present invention has been made in view of the above circumstances, and an object thereof is to reduce the weight of a core material and to facilitate the handling thereof, and to wind the core material into a roll. The point is that it is possible to increase the degree of freedom in selecting a binding material, a tightening device, and the like for tightening the flat body.

[0005]

In order to achieve the above object, according to the present invention, a flexible flat body is wound around a core material in a roll shape, and the required portions of the wound flat body are bound together. A method of winding a flexible flat body tightened with a material,
As the core material, a bag made of a resin film in which air is injected is used, and the operation and effect thereof are as follows.

[0006]

[Operation] While securing the volume required for the core material,
Since only air is injected into the inside, the weight of the core material can be significantly reduced. Moreover, when the flat body wound around the core material is tightened with the binding material, the flat body portion and the bag portion corresponding to the tightening portion are constricted and deformed inward in the diametrical direction. Even if it is not necessary, it is possible to suppress the shift movement of the flat body wound in a roll shape in the direction of the roll axis and the slipping out of the core material.

[0007]

Therefore, the weight of the core material can be reduced to facilitate the handling of the flat body wound in a roll shape, and a binding material for tightening the flat body wound in a roll shape or the like. The degree of freedom in selecting the tightening device can be increased. Moreover, since the bag body is used as the core material, it becomes possible to manufacture a bag body in which air is injected at the time of winding the flat body or immediately before the start of the winding work. The material can be stored advantageously in terms of space.

That is, it is possible to specify the push-up position by the lifting mechanism D. Therefore, it is possible to prevent a winding error due to the raised portion generated in the unwound portion of the flat body 1 positioned inside reaches the winding device B and is wound as it is. Moreover, by specifying the position where the strip-shaped insect-like ridges are generated to be pushed up by the group of rollers 53, at this position, the flattened flat bodies 1 overlapped with each other.
Since an air gap S is generated between the unwound portions of the flat body 1, when the unwound portion of the flat body 1 passes through the group of rollers 53, the unwound portions of the flat body 1 are relatively moved in the transport direction. It will slide and move, and the worm-like bump will be completely eliminated. In addition, when the left and right fluid pressure cylinders 51 are rapidly extended and the rollers 53 are pushed up and rapidly switched to the working state, the flat body 1 being wound by the winding device B is rewound in the rewinding direction.
