## Abstract

A window manufacturing apparatus includes a transporting table on which a target substrate is to be mounted, the transporting table including a first portion and a second portion having a greater thickness than the first portion, a plurality of suctioning ports on a suctioning table, the plurality of suctioning ports being configured to suction the target substrate, and an attachment device configured to attach a protective film to the target substrate suctioned to the suctioning table. In a state in which the target substrate mounted on the transporting table is suctioned to the suctioning table, the plurality of suctioning ports overlap the second portion of the transporting table and do not overlap the first portion of the transporting table in a plan view.

## Claims

### Claim 1

A window manufacturing apparatus comprising:
a transporting table on which a target substrate is to be mounted, the transporting table comprising a first portion and a second portion on opposite sides of the first portion and having a greater thickness than the first portion, the first and second portion defining a groove in the transporting table;
a suctioning table spaced from the transporting table and comprising a plurality of suctioning ports, the plurality of suctioning ports being configured to suction the target substrate and, when suctioning the target substrate and mounting the target substrate on the transport table, the suctioning table is configured to be positioned over the transporting table such that the plurality of suctioning ports overlap the second portion of the transporting table and not overlap the first portion of the transporting table in a plan view; and
an attachment device configured to attach a protective film to the target substrate suctioned to the suctioning table.

### Claim 2 (depends on 1)

The window manufacturing apparatus of claim 1, wherein the target substrate comprises a folding portion and a non-folding portion adjacent to the folding portion, and, in a state in which the target substrate is mounted on the transporting table, the folding portion overlaps the first portion and the non-folding portion overlaps the second portion.

### Claim 3 (depends on 2)

The window manufacturing apparatus of claim 2, wherein, in a state in which the target substrate is suctioned to the suctioning table, the plurality of suctioning ports overlap the non-folding portion.

### Claim 4 (depends on 1)

The window manufacturing apparatus of claim 1, wherein the target substrate comprises glass.

### Claim 5 (depends on 1)

The window manufacturing apparatus of claim 1, wherein, in a state in which the target substrate is mounted on the transporting table, the target substrate contacts an upper surface of the second portion and does not contact an upper surface of the first portion.

### Claim 6 (depends on 1)

The window manufacturing apparatus of claim 1, wherein, in a state in which the target substrate is suctioned to the suctioning table, the target substrate contacts a lower surface of the suctioning table.

### Claim 7 (depends on 6)

The window manufacturing apparatus of claim 6, wherein the lower surface of the suctioning table has a surface roughness of about 10 μm to about 50 μm.

### Claim 8 (depends on 1)

The window manufacturing apparatus of claim 1, further comprising a transporting device configured to transport the target substrate to the transporting table and to mount the target substrate on a mounting surface of the transporting table.

### Claim 9 (depends on 8)

The window manufacturing apparatus of claim 8, wherein the transporting table comprises:
a first transporting table configured to receive the target substrate from the transporting device; and
a second transporting table configured to rotate the target substrate mounted on the first transporting table.

### Claim 10 (depends on 1)

The window manufacturing apparatus of claim 1, wherein the protective film comprises polyethylene terephthalate (PET).
