However, the binding band described in the above patent document has at least one of the problems described below.
(1) The protrusion has a shape that gradually expands in diameter from the front end side to the rear end side of the band, and when pulling out the band, a strong tensile force is applied to the enlarged diameter side of the protrusion so as to greatly deform it. The eyelet hole must be passed through, and the expected convenience cannot be obtained in actual use.
(2) Since there are two protrusions that pass through the eyelet holes, when the band is completely pulled out, the protrusion near the rear end of the band must pass through the eyelet holes on one of the sheets. The protrusion near the tip side of the sheet must pass through the eyelet holes of both adjacent sheets.
That is, when the band is pulled out, the band is strongly pulled a total of three times, which not only increases the possibility of damage to the band but also increases the labor of the operator.
(3) Due to the structure of the pull-out prevention part of the band, it is necessary to configure the band part hooked on the pull-out prevention part to have a circular cross-sectional shape, and application to other cross-sectional shapes, such as belt-shaped binding bands exhibiting a rectangular cross-sectional shape. is difficult.
