2. The liner pasting machine (100) as claimed in claim 1, wherein the ear flap folding and pasting apparatus (106) comprises a bar (120) parallel to the rigid base (104) to mount the driver (112), the holding unit (114), the air blower (116), and the ear flap folder (118).

3. The liner pasting machine (100) as claimed in claim 2, wherein each of the driver (112), the holding unit (114), the air blower (116), and the ear flap folder (118) is mounted on the bar (120) by a coupler (124, 126, 128, 130) to move along an axis of the bar (120).

4. The liner pasting machine (100) as claimed in claim 1, wherein the glue applicator (102) applies glue on a liner pasting portion of the carton sheet (108); and the liner pasting machine (100) comprising a suction drum to paste a liner on the liner pasting portion of the carton sheet (108) received on the rigid base (104).

5. The liner pasting machine (100) as claimed in claim 1, wherein the ear flap folder (118) is a bend metallic rod (402) having one end (406) inclined at the first acute angle with respect to the plane of the rigid base (104) and the second acute angle with respect to the holding unit (114).

6. The liner pasting machine (100) as claimed in claim 5, wherein the bend metallic rod (402) and the holding unit (114) are adjacent to each other, and the air blow (116) is provisioned near the bend portion of the bend metallic rod (402), such that a nozzle of the air blower (116) points to an area of the rigid base (104) below the holding unit (114).

7. The liner pasting machine (100) as claimed in claim 1, wherein the driver (112) comprises a belt (202) rotatably mounted on bearings (204) to grip and move the carton sheet (108) against the rigid base (104).

8. The liner pasting machine (100) as claimed in claim 1, wherein the glue applicator (102) is provided on a roller (110), the roller (110) receives glue on the glue applicator (102) and transfers glue on the upper surface portions of the carton sheet (108).

9. The liner pasting machine (100) as claimed in claim 1, wherein the rigid base (104) has vacuum holes.

10. An ear flap folding and pasting apparatus (106) for a liner pasting machine (100), comprising:
a driver (112) to grip and move a carton sheet (108) over a rigid base (104);
an air blower (116) to blow a pressurized air beneath an ear flap portion of the carton sheet (108) to lift the ear flap portion about a crease defining the ear flap portion, wherein the carton sheet (108) is received by the ear flap folding and pasting apparatus (106) on the rigid base (104) from a glue applicator (102) that applies glue on an upper surface of at least the ear flap portion of the carton sheet (108);
a holding unit (114) to hold the carton sheet (108) near the crease, such that when the carton sheet (108) passes below the holding unit (114), the air blower (116) lifts the ear flap portion of the carton sheet (108) about the crease; and
an ear flap folder (118) having a curved profile and an inclined stance at a first acute angle with respect to a plane of the rigid base (104) and a second acute angle with respect to the holding unit (114), wherein, when the carton sheet (108) is moved on the rigid base (104), the curved profile and the inclined stance of the ear flap folder (118) exerts a force on the lifted ear flap portion to fold the lifted ear flap portion about the crease to paste the glued surface of the ear flap portion with an upper surface of the carton sheet (108).

11. The ear flap folding and pasting apparatus (106) as claimed in claim 10, comprising a bar (120) parallel to the rigid base (104) to mount the driver (112), the holding unit (114), the air blower (116), and the ear flap folder (118).

12. The ear flap folding and pasting apparatus (106) as claimed in claim 11, wherein each of the driver (112), the holding unit (114), the air blower (116), and the ear flap folder (118) is mounted on the bar (120) by a coupler (124, 126, 128, 130) to move along an axis of the bar (120).

13. The ear flap folding and pasting apparatus (106) as claimed in claim 10, wherein the ear flap folder (118) is a bend metallic rod (402) having one end (406) inclined at the first acute angle with respect to the plane of the rigid base (104) and the second acute angle with respect to the holding unit (114).

14. The ear flap folding and pasting apparatus (106) as claimed in claim 10, wherein the bend metallic rod (402) and the holding unit (114) are adjacent to each other, and the air blower (116) is provisioned near of the bend portion of the bend metallic rod (402), such that a nozzle of the air blower (116) points to an area of the rigid base (104) below the holding unit (114).

15. The ear flap folding and pasting apparatus (106) as claimed in claim 10, wherein the driver (112) comprises a belt (202) rotatably mounted on bearings (204) to grip and move the carton sheet (108) against the rigid base (104).
