Claims

[Scope of utility model registration request]

A rotating table that automatically stops at a set position after rotating a set number of times, and a film unwinding device provided on a base frame independently of the rotating table,
At least the rotary table is closed so as to protrude from the upper surface of the rotary table when the rotary table is stopped, and the end of the film is clamped, and when the rotary table is rotated, it does not protrude from the upper surface of the rotary table at a set timing. The gripper is provided with a gripper that opens to release the end of the film, is provided on the base frame facing the rotary table, and has a swing radius that allows it to come into contact with the side surface of the packaged object immediately after the rotary table stops. A film guide arm having a film presser roller that swings to attach the film to the object to be packaged and moves a part of the film to a position where the gripper grips the film, and a film guide arm between the film presser roller and the gripper. In an automatic pallet stretch packaging machine equipped with a cutter for cutting the film held between the grippers, multiple layers of films wrapped around the side wall of the object to be packaged are placed on the film guide arm. An automatic pallet stretch packaging machine characterized by being equipped with a heat sealer that heat-seals multiple strips parallel to the stretching direction or at an angle of 45 degrees.
