PURPOSE: To allow the arrangement to function also as elevating mechanism at the time of splicing, by permitting a bobbin holder to operate in such a way as stopping once or more on the midway for stepping elevation, when a bobbin with completed winding shall rise from the takeup roller up to the bobbin replacement position.
CONSTITUTION: A cam 31 is provided at the center of the lower part of No.1 cover 21a for an elevating mechanism, and a lever 35 interlocked therewith rotates and sinks for a certain distance with rotation of the cam 31, so that a bobbin holder 14 is turned always a certain specific angle. Therefore the holder 14 turns for this specific angle in compliance with increase of the winding diameter on the bobbin 13, which is now heaved from the drum 12 for a certain distance. When a cut yarn sensing device senses the yarn being cut, the bobbin 13 is heaved a certain distance, and a yellow lamp will light up and the splicing machine stop for operation of splicing. After completion of splicing, the holder 14 sinks while rotating, and takeup is resumed. Accordingly the elevating mechanism for bobbin replacement can be used also at the time of splicing to ensure that the construction is made simple.
