ようにしたことを特徴とするカーペツト伸張機。 It is equipped with a piston connected to the rear end of a rod with a needle head fixed at the tip, and a cylinder in which the piston is slidably fitted, and an operating rod fixed to the top surface of the main body is operated against the force of a spring. When pressed downward, compressed air is introduced into the rear end of the air cylinder and the needle head moves forward. When the operating rod returns to its original position by the force of the spring, compressed air is introduced into the front end of the air cylinder and the needle head moves forward. A carpet stretching machine characterized by a head that moves backwards.
