According to the embodiment, the pressing member PU may include a material having high thermal conductivity such as graphite or stainless. As a result, the pressing member PU can heat the glass GS. In one example, the pressing member PU may be heated by an external heating member. The glass GS in contact with the pressing member PU can be heated by the pressing member PU. As another example, the pressing member PU may include a heating mechanism for generating heat. By heating the pressing member PU to the heating mechanism, the heat of the pressing member PU can be transmitted to the glass GS.

The molded member MU is disposed under the pressing member PU and the glass GS is disposed between the molded member MU and the pressing member PU. The molded member MU supports the glass GS and is capable of molding the first molded portion MA1 and the second molded portion MA2 of the glass GS facing in the first direction DR1.

According to the embodiment of the present invention, the first formed portion MA1 and the second formed portion MA2 of the glass GS can be bent in the third direction DR3 through the intake operation by the opening portion OP have.

The suction unit HPU may be attached to the opening OP included in the bottom portion Hb. Depending on the operation of the suction unit (HPU), the space between the housing member (HU) and the molded member (MU) can be kept in a vacuum state. The suction unit HPU may include a suction pad PD attached to the opening OP, a connection pipe CN connected to the suction pad PD, and an inhaler VCM connected to the connection pipe CN. The inhaler (HPU) may be disposed under the housing member (HU).

The suction pad PD may be disposed on the bottom portion Hb so as to overlap with the opening OP. In addition, in the first direction DR1, the width of the suction pad PD may be larger than the width of the opening OP.

One end of the connector CN is connected to one part of the suction pad PD and the other end is connected to a part of the suction unit VCM.

The suction unit VCM is connected to the other end of the connection pipe CN to perform an intake operation. As the inhaler VCM performs the suction operation, the air filled in the spaced space between the housing member HU and the molded member MU can be absorbed through the suction pad PD.

As the pressing member PU presses the glass GS, the protrusions PT can press the springs SP in the third direction DR3, respectively. In this case, the protrusions PT can be respectively inserted into the holes HO. For example, the protrusions PT may be entirely inserted into the holes HO, or may be partially inserted.

As a result, the length in the third direction DR3 between the first supporting portion Hs1 and the first sub-surface SSb1 can be shorter than the first length L1a. The length in the third direction DR3 between the second supporting portion Hs2 and the second subordinate surface SSb2 may be shorter than the first length L1a. Illustratively, the first support portion Hs1 and the second support portion Hs2 may be in direct contact with the first sub-back SSb1 and the second sub-back SSb2, respectively, or may be shorter than the first length L1a And can be separated from each other by a length.

Thereafter, as the first shaping portion MA1 and the second shaping portion MA2 perform the operation of Fig. 4C, the projections PT can press the springs SPa, respectively. As a result, the protrusions PT can pass the holes HOa and press the springs SPa in the third direction DR3. That is, the thickness of the protrusions PT in the third direction DR3 may be greater than the depth of the holes HOa.

The inhaler HPUa may be disposed on the support SSp so as to overlap the opening OP. The structure and operation of the inhaler HPUa are omitted as they are substantially the same as the structure and operation of the inhaler HPU described in Fig.

That is, after the glass GS is heated, until the first and second molded parts MA1 and MA2 are bent beyond 90 degrees from the front part CA, the height of the cylinder Cb is increased in the third direction DR3 The first length may have a first length. Here, the glass GS can be heated by an external heating mechanism.

Referring to Fig. 7B, the cylinder Cb can be moved into the motor Ca by the operation of the motor Ca. A space for disposing the cylinder Cb may be formed in the motor Ca. In this case, the height of the cylinder Cb between the projecting portion PTa and the motor Ca may be shorter than the first length in the third direction DR3.

In addition, as the cylinder Cb is moved into the motor Ca, a protrusion PTa coupled to the cylinder Cb can be inserted into the hole HOa. Thus, each of the first and second molded parts MA1, MA2 described previously in Fig. 4C can be molded into an edge part and a back part.

Wherein the thickness of each of the projections in the thickness direction of the glass is greater than the depth of the holes. A housing member including a bottom portion parallel to the plane defined by the first direction and the second direction and having at least one opening defined therein and a support portion having a stepped portion that is bent from the bottom portion and facing the first portion, Disposing a forming member on the substrate;
A front surface facing the front surface, a rear surface facing the bottom surface, a plurality of side surfaces connecting the front surface and the back surface, two of the side surfaces facing each other in the first direction are bent from the back surface, A first sub-side having a first sub-side, a first sub-side having a stepped surface with the rear surface, a sub-surface bent from the first sub-side and facing the support portion, and a second sub-side connecting the sub- Disposing a glass on the front surface among the surfaces of the glass substrate;
A front portion of the glass superimposed on the front surface and an edge portion extending from the front portion and not overlapping with the front surface are bent in the thickness direction of the glass through the second sub side having a curved shape, Heating;
Inserting through an inhaler disposed at a lower portion of the housing member and coupled to the opening; And
The spacing between the sub-backside and the support portion being spaced apart from each other in the thickness direction is reduced,
Wherein the edge portion disposed between the sub-back and the support portion includes a sub-front portion parallel to the front portion and a bending portion connecting the front portion and the sub-front portion. 18. The method of claim 17,
Wherein the step of reducing the spacing between the sub-
