2 to 7, the folding-groove generating apparatus 100 according to the present embodiment includes a fixed body 110, a moving body 120, a first folding-groove generating member 131, A folding groove creating member 132, a third folding groove creating member 133, and a supporting member 140. [

This folding groove forming apparatus 100 is configured such that when the front cover (see 16 in Fig. 1) of the paper tube (see Fig. 1) is moved toward the rear side of the paper tube (See FIG. 1, see FIG. 1) is formed on the front cover (see FIG. 1, 16) so that the folded sheets (see FIG. This will be described later.

The fixed body 110 extends in one direction.

The fixed body 110 may have a columnar shape extending in one direction. At this time, the fixed body 110 may have a rectangular cross section, but not limited thereto, and may have various cross sections. Corner portions of the fixed body 110 may be tapered or rounded.

A protruding portion 111 of a rack gear shape extending in the extending direction of the fixed body 110 may be formed on one surface of the fixed body 110. The protrusions 111 may protrude from one surface of the fixed body 110, but the present invention is not limited thereto.

The width of the concave and convex portions 111 may be narrower than the width of the fixed body 110. The convex-concave portion 111 doubles the effect of the movement restricting means 150, which will be described later.

The movable body 120 is coupled to the fixed body 110 so as to be movable in the extending direction of the fixed body 110.

For example, the movable body 120 may be formed with a sliding groove 121 through which the fixed body 110 is inserted to allow sliding movement. The sliding groove 121 extends in the sliding direction of the moving body 120. At this time, the end face of the sliding groove 121 may have a shape corresponding to the end face of the fixed body 110.

As another example, although not shown, the fixed body may be formed with a sliding groove extending in the extending direction of the fixed body, and the moving body may be formed with a sliding coupling portion that is inserted into the sliding groove of the fixed body and is slidable.

The moving body 120 may have a rectangular parallelepiped shape, but is not limited thereto. The corner of the moving body 120 may be rounded, but is not limited thereto.

The cross sections of the openings 122 and the sliding grooves 121, which are interconnected to each other, may have a shape as shown in FIGS. 5 and 6.

The opening 122 may extend entirely in the extending direction of the moving body 120, as shown in FIGS. Or the opening may be partially extended in the extending direction of the moving body 120, although not shown.

At one side of the distal end of the fixed body 110, a latching part 113 is formed. The locking part 113 may be integrally formed with the fixing body 110 by casting or injection molding, for example.

The locking part 113 may be arranged in a direction perpendicular to the extending direction of the fixed body 110, for example.

The locking part 113 prevents the moving body 120 moving along the extending direction of the fixed body 110 from being detached from the tip of the fixed body 110. In other words, the moving body 120 moving toward the tip of the fixed body 110 is caught by the catching part 113 and can not move any more.

The distal end of the fixed body 110 and the distal end of the locking part 113 may be formed on the same plane as shown in Figs. At this time, the tip of the fixing body 110 and the tip of the locking part 113 may be placed on a plane perpendicular to the extending direction of the fixing body 110. [

The distal end of the moving body 120 facing the rear end of the locking part 113 and the locking part 113 may be placed on a plane perpendicular to the extending direction of the fixing body 110. [

The movable body 120 can advance forward of the fixed body 110 until the tip of the movable body 120 comes into surface contact with the tip of the engaging portion 113 (see FIG. 2). At this time, a step structure may be provided between the tip of the movable body 120 and the tip of the fixed body 110, which are located on the opposite side of the fixed body 110 on which the engaging portion 113 is formed. The step structure will be described later.

The distal end of the moving body 120 facing the rear end of the locking part 113 and the distal end of the moving body 120 positioned on the opposite side of the side where the locking part 113 of the fixed body 110 is formed The other end can be placed on the same plane.

In another embodiment, one end of a moving body (see 120 in Fig. 3) opposite to the rear end of the latching portion (see 113 in Fig. 3) and a latching portion 3) of the movable body (refer to 120 in Fig. 3) located on the opposite side of the side where the movable base (see 113 of Fig. 3) is formed can be placed on another plane which is parallel and different.

The ends of the first folding groove creating member 131, the second folding groove creating member 132, and the third folding groove creating member 133 may be placed on the same plane. In this case, the ends of the first folding groove creating member 131, the second folding groove creating member 132, and the third folding groove creating member 133 are provided with a first folding groove, a second folding groove, Grooves, and third folding grooves at the same time.

The first folding groove creating member 131, the second folding groove creating member 132, and the third folding groove creating member 133 respectively form the first folding groove, the second folding groove and the third folding groove The process will be described later.

A supporting member 140 is supported on the moving body 120. For example, the support member 140 may be inserted into one side of the rear end of the moving body 120 and coupled to the moving body 120 in a pin-wise manner. The support member 140 may have a columnar shape and a circular cross-section.

The support member 140 may be arranged at a right angle to the same plane where the ends of the first folding groove creating member 131, the second folding groove creating member 132, and the third folding groove creating unit 133 are located at the same time . Or the support member 140 may be disposed on a plane parallel to the plane on which the tip of the fixed body 110 is placed.

The support member 140 is formed so that the first folding groove creating member 131, the second folding groove creating member 132 and the third folding groove creating member 133 are engaged with the front cover (see FIG. 1) (Refer to FIG. 1, reference numeral 10), the folding-groove generating apparatus 100 is supported on one side surface (refer to 10a in FIG.

At this time, the tip of the support member 140 can contact one side thickness surface (see 10a in Fig. 1) of the paper tube (see 10 in Fig. 1) Can be supported in a direction perpendicular to one side thickness surface (see 10a in Fig. 1). This will be described later.

In this embodiment, the first folding groove creating member 131, the second folding groove creating member 132, the third folding groove creating member 133, and the supporting member 140 are formed by the folding groove forming apparatus 100 In order from the leading end to the trailing end.

The distance L ₁ between the end of the first folding groove creating member 131 and the end of the second folding groove creating member 132 is smaller than the distance between the tip of the fixed body 110 and the end of the moving body 120 is equal to the distance between the leading end (L _S) (see Figs. 2 and 3).

More specifically, as described above, a step structure may be provided between the distal end of the fixed body 110 and the distal end of the movable body 120 on the opposite side of the fixed body 110 on which the engaging portion 113 is formed.

The distance L _S between the tip of the fixed body 110 and the tip of the movable body 120 is equal to the step size L _S of the step structure at the end of the first folding groove creating member 131, Is the same as the distance (L ₁ ) between the ends of the folding groove generating member 132.

For reference, the step size L _S of the step structure can be varied during the sliding movement of the movable body 120 with respect to the fixed body 110 (see FIGS. 2 and 3). The distance L ₁ between the end of the first folding groove creating member 131 and the end of the second folding groove creating member 132 may be varied corresponding to the size of the step difference L _S in this embodiment (See Figs. 2 and 3).
