Description

The present invention relates to a method for manufacturing a core having an adhesive tape wound layer in which an adhesive tape is wound around a surface of a flat core body rotatably suspended on a flat frame.

Conventionally, there is an adhesive tape body in which an adhesive tape or other adhesive tape is wound around a core formed in a flat shape, such as a ring or a plate, but these adhesive tape bodies are manually supported and required for the wound adhesive tape. It is used by peeling off the length by hand.It is not intended to be used by suspending it on a frame or the like.It is difficult to rewind or cut the required length of adhesive tape when using. There are disadvantages such as.

The present invention makes it possible to easily manufacture a core body provided with a wound layer of an adhesive tape on the surface of a flat core body that is rotatably suspended on a flat frame body. The core can be used by attaching it to the flat frame, and the adhesive tape can be easily rewound and cut, and is easy to use.

 Hereinafter, the present invention will be described with reference to examples.

A flat core body (2) is rotatably suspended via a support portion (3) on opposite side walls (4) of a hollow portion (1a) of a flat frame (1). . In this supporting example, for example, bearings (3a) or protruding shafts are provided on opposite side walls (4) of the hollow portion (1a), and the hollow portion side walls (4) are provided on both side surfaces (5) of the core body (2). The bearing (3a) or the protruding shaft (13b) or bearing corresponding to the protruding shaft
The core body is rotatably formed by fitting each other.
(7) is a penetrating or recessed hole provided in the side surface portion (5) of the core body (2), which is used for holding the adhesive tape when it is wound, and is engraved as necessary. The flat core body (2) has a core (6a) having an adhesive tape wound layer (6a) formed by winding a predetermined length of an adhesive tape having a required width, for example, 2 to 5 m around an outer peripheral surface (2a) thereof. ), And is wound around the flat frame body (1) to rewind the wound layer (6a) of the adhesive tape for use.

A core (6) having an adhesive tape wound layer (6a) in which a fixed length wound layer (6a) such as an adhesive tape is formed on the outer peripheral surface (2a) of the flat core body (2) is It is manufactured as follows. An outer peripheral surface (2a) of the flat core body (2), that is, an outer peripheral surface (12a) formed to have a peripheral length substantially corresponding to the peripheral length of the adhesive tape winding surface, and a circular cross section On the outer peripheral surface (12a) of the core (12), a predetermined length of an adhesive tape having a required width, for example, 2 to 5 m, is wound by a conventional method with or without a flexible paper layer or the like. Thus, a circular wound tape body (14) having the wound layer (14a) of the adhesive tape on the core (12) is formed. The above-mentioned circular tape (1
4) The core (12) has the required shape-retaining properties of paperboard, rubber, plastic such as synthetic resin, metal, wood and bamboo, or a composite material of these, and is moderately applied by external force such as pressing if necessary. The width of the outer peripheral surface (12a) of the winding core (12) can be adjusted as necessary to the outer peripheral surface (2) of the core body (2).
The width of a) or the width of the adhesive tape to be wound can be substantially the same.

The circular wound tape body (14) formed as described above is pressed, for example, from the outer peripheral surface thereof, and is appropriately flattened, and then the deformed winding core (22) is flattened. To obtain a flattened adhesive tape wound layer (24a) (FIG. 8). Alternatively, after the core (12) is extracted from the circular wound tape body (14) by an appropriate method, the adhesive tape wound layer (14a) of the remaining circular wound tape body (14) is removed from its outer peripheral surface. The wound layer (24a) of the pressure-sensitive adhesive tape which is pressed in the direction of the center to be appropriately flattened is obtained (FIG. 9).

Next, the flat core body (2) is pressed, if necessary, into the hollow portion (15) from which the core of the flattened pressure-sensitive adhesive tape winding layer (24a) is extracted. A core body (6) fitted from one side and having a required adhesive tape wound layer (6a) without a gap or the like between the wound layer (24a) and the core body (2). Is obtained. The flat core body (2) to be fitted into the hollow portion (15) can be easily fitted by appropriately removing the corners of the side edges of the fitting tip.
Further, an adhesive, an adhesive, a thin paper, or the like can be fitted into the outer peripheral surface (2a) of the flat core body as necessary.

The present invention has a configuration as described above, and the core having the adhesive tape wound layer can be easily manufactured without requiring skill or special equipment, and is formed into a flat frame. If installed, it is lightweight and bulky, suitable for carrying, etc., and the wound adhesive tape can be easily rewound and used conveniently.
