ABSTRACT:
An .alpha.-shaped torsion springs having a cylindrical coiled portion and first and second leg portions projecting from opposite ends of the coiled portion is conveyed along a conveyor rail. The conveyor rail has a base wall, first and second side wall which project upward on opposite sides of the base wall and extend in parallel to each other, a coil support surface which projects horizontally above the base wall from the second side wall toward the first side wall and terminates at a free edge spaced from the first side wall, and a partition wall which projects horizontally above the base wall from the first side wall toward the second side wall and terminates near the free edge of the coil support surface above the same. The .alpha.-shaped torsion spring is conveyed along the conveyor rail with the coiled portion resting on the coil support surface in a vertical position, the first leg portion projecting above the partition wall and the second leg portion projecting below the partition wall and being spaced from the base wall. The edge of the partition wall opposed to the second side wall prevents the leg portions from interfering with the first side wall during conveyance.
