in a conveyer system including a tubular guide way having a curved guide way section , a magnet - mounted inner slider slidably disposed in the tubular guide way , a pressure source connected to the tubular guide way to feed the interior thereof with a pressurized air thereby to move the inner slider in and along the tubular guide way , and a magnet - mounted outer slider movably disposed on said tubular guide way . the magnet of the outer slider establishes a magnetic connection with the magnet of the inner slider so that movement of said inner slider can induce movement of the outer slider in the same direction . in order to smooth the movement of the inner slider in the tubular guide way , the inner slider is so constructed as to be flexed along its longitudinal axis when an external force is applied thereto .
