PURPOSE:To make it possible to enhance the efficiently of working and the quality control, by retracting a lower conveyer until an article loaded thereon comes to a position direct below the downstream end of an upper conveyer, and by advancing the upper and lower conveyers so that an article on the upper conveyer is dropped so that they are partly superposed and lined up. CONSTITUTION:An ahead uncured tube 5 on a lower conveyer 51 is conveyed to a position direct below the downstream end 37 of an upper conveyer 28 due to retraction of the lower conveyer 51 so that a sensor detects one widthwise end 5b of the tube 5 and delivers a signal to a control means. When the number of counts reaches a set value, the upper conveyer 28 is stopped. At this time one widthwise end of an uncured tube 5 makes into contact with the upper surface of center section of the ahead uncured tube 5. Then, when the upper and lower conveyers 28, 51 are advanced at an equal speed, the uncured tube 5 is dropped from the upper conveyer 28 while it is partly superposed on the ahead tube 5, and when the dropped tube 5 is conveyed to a predetermined position, the rotating direction is reversed so that the conveyer 51 travels in the direction G. Accordingly, the superposed tubes 5 are retracted until their endmost tails come to a position direct below the downstream end 37, thereby the uncured tubes are lined up with they being superposed with each other by 40% of the width thereof.
