Abstract

The adhesive tape cutter comprises a body bracket with a support that rotatably supports an adhesive-tape roll and a cutting section to cut adhesive tape pulled out from the adhesive-tape roll supported. A path to pull out the adhesive tape from the support to the cutting section is a double-portion forming section that comprises adhesive face-side members disposed on a side faced by an adhesive face of the adhesive tape and non-adhesive face-side members disposed on a side faced by a non-adhesive face thereof that folds a longitudinal side edge of a predetermined width of the adhesive tape in a direction that the adhesive face is facing to stick when the adhesive tape is inserted between both the member groups and pulled out pressing against the members. A tape cover is provided outside the support and pivotably coupled to the body bracket.

Claims

1. An adhesive tape cutter comprising:

a body bracket provided at its one end with a support that rotatably supports an adhesive-tape roll and at the other end with a cutting section to cut adhesive tape pulled out from the adhesive-tape roll supported by the support,

wherein provided in a path to pull out the adhesive tape through from the support to the cutting section in the body bracket is a double-portion forming section that includes adhesive face-side members disposed on a side faced by an adhesive face of the adhesive tape and non-adhesive face-side members disposed on a side faced by a non-adhesive face thereof and that, after the adhesive tape is inserted through between the adhesive face-side members and the non-adhesive face-side members, folds at least one side edge of a predetermined width of the adhesive tape in a direction that the adhesive face is facing to form a double portion as a non-adhesive portion along its longitudinal direction when the adhesive tape is pulled out, and

wherein a tape cover is provided outside the support and pivotably coupled to the body bracket so as to cover at least part of the adhesive-tape roll supported by the support, to contact an outer circumferential surface of the adhesive-tape roll and form part of a grip,

wherein the double-portion forming section comprises

a bending roller as one of the adhesive face-side members that contacts the adhesive face of the adhesive tape except the side edge of the predetermined width to be bent;

a bending guide block as one of the non-adhesive face-side members that is placed opposite an end face of the bending roller and contacts and presses against the non-adhesive face of the side edge of the adhesive tape, not contacting the bending roller, to sandwich the side edge between the end face of the bending roller and itself and bend the side edge of the predetermined width in the direction that the adhesive face is facing;

a folding guide block as one of the adhesive face-side members that has a guide portion contacting and pressing against the non-adhesive face of the bent side edge to bend the side edge to be at an acute angle and that is placed on the side faced by the adhesive face of the adhesive tape; and

a press roller that contacts and presses against the non-adhesive face of the adhesive tape having the side edge folded to stick together opposite adhesive faces of the folded adhesive tape;

wherein the bending guide block has an extending end portion which extends further toward the folding guide block side than the circumferential surface of the bending roller; and

wherein the extending end portion has a guide protrusion, the guide protrusion guiding and further bending the side edge to be at a bending angle of an acute angle with the opposite adhesive face by contacting the non-adhesive face of the side edge that is bent.
