Adhesive-tape cutter and adhesive tape

摘要

An adhesive tape cutter provided with a double-portion forming means that folds a longitudinal side edge of a predetermined width of adhesive tape in the direction that its adhesive face is facing to form a double portion as a non-adhesive portion by pulling out the adhesive tape through between adhesive face-side members disposed on the side faced by the adhesive face and non-adhesive face-side members disposed on the side faced by a non-adhesive face thereof with both the members contacting and pressing against the adhesive tape. The non-adhesive face-side members are supported by an open/close member that is openable and closable, and the open/close member is configured to be movable between a closed position where the non-adhesive face-side members contact and press against the adhesive tape through the double-portion forming means and an open position where the non-adhesive face-side members do not, and in the open position, the non-adhesive face-side members are apart from the adhesive face-side members such that a path for the adhesive tape to be inserted through is opened up.
