The invention relates to a semi-automated liner insertion device and a semi-automated method of inserting a liner cut piece into an outer covering to form a combine (6). The semi-automated device comprises a height adjustable frame (10) on which a semi-automated liner insertion platform (1) is mounted and which is capable of moving on a pair of rails (3) with the help of a pneumatic cylinder (8) 10 connected to a cross member (2) provided with rolling or sliding mechanism (2A). The pneumatic cylinder (8) is controlled by a pneumatic valve (12) or a solenoid valve (12). The semi-automated method of the invention comprises facilitating an automated movement of the liner insertion platform (1) onto which a liner cut piece (4) is placed manually, followed by a manual placement of an outer 15 covering piece (5) on the liner cut piece (4) to form a combine (6), following which the liner insertion platform is retracted semi-automatically to complete one cycle.
