Abstract: An article packaging apparatus with a cylindrical cassette having a tube made of resin fitted on the outer peripheral surface thereof is mounted below a charging station for charging articles. Heated press heads for heating and fusing the resin tube are arranged below the cassette. The heated press heads are moved from a standby position remote from the resin tube to a clamping position for clamping the tube. The heated press heads are then lowered a predetermined distance from the clamping position in order to pull the resin bag and move the heated press heads to a fusing position for fusing said tube. The heated press heads are lowered a short distance from the fusing position and the heated press heads are moved to a separating position for separating an individual bag from the resin tube.

Abstract: A spring heat treating furnace in which untreated springs are charged through a charging port in the body thereof, the springs being heat-treated while being conveyed along a conveyance passageway inside the body. The heat-treated springs are discharged from a discharge port in the furnace body, said conveyance passageway being formed into a spiral passageway capable of arranging said springs in the direction of conveyance. A passageway vibrating device is disposed at the lower portion of said conveyance passageway for vibrating the passageway to convey the springs in a discharging direction.
