In general, tape cleaners are widely used because they are suitable for removing various foreign substances such as dust, hair, lint, etc. adhered to the surface of textile products such as bedding, clothing, and carpet. In general, a tape cleaner includes an adhesive tape roll on which an adhesive tape is mounted, a support roller inserted into the adhesive tape roll to support the adhesive tape roll, and both ends are coupled to both ends of the support roller to support the support roller. The support frame, and a front end is composed of a handle connected to the support frame.

A cutting line 130 for cutting is formed on the adhesive tape of such a tape cleaner for each rotation of the adhesive tape roll. When foreign matter adheres to the adhesive tape and the adhesive strength disappears, the adhesive layer to which the foreign matter adheres along the cutting line 130 may be removed once to expose a new adhesive layer.

In the case of using a tape cleaner for bedding, clothing, carpet, etc., since the adhesive strength rapidly deteriorates just by rubbing a small area, the tape cleaner tends to be quite clumsy even though the price is not cheap. However, since tape cleaners using adhesive tape rolls with cut lines must be used along the cut lines formed at regular intervals, sometimes the entire surface must be removed even if sufficient foreign matter does not adhere to the adhesive surface, and the winding surface becomes smaller as it goes inside. , There was a lot of wasted part because the unused side was removed.

Moreover, in the conventional tape cleaner, as shown in FIG. 1, in order to solve the problem of the adhesive protruding from the side of the adhesive tape, the edge portions of both sides in the width direction of the tape are non-coated adhesive portions without coating the adhesive. Forming 112. Therefore, there is a problem that the entire width of the adhesive tape is not utilized and part of the adhesive tape is discarded, resulting in wasted.
