An apparatus for making wedged plate has an extruder to provide melted plastic material. A die head has a channel with an inlet and an outlet. The inlet of the die head is connected to an outlet of the extruder. The outlet of the die head has a thick side and a narrow side. A rolling device has two rollers and a space between the rollers. The space has a thick portion and a narrow portion at opposite sides. The space of the rolling device is aligned with the outlet of the die head, so that the plastic material flows into the space of the rolling device via the die head and is rolled by the rollers. A cutting device is arranged behind the rolling device to cut the rolled plastic material to get wedged plates.
