PROBLEM TO BE SOLVED: To provide an automatically label seaming device and an automatically label seaming method in a labeling machine capable of reducing time and costs for automatic labeling operation without stopping the whole labeling machine and a conveyer at the time of replacing or supplying labels L1 and L2. SOLUTION: The first labels L1 or the second labels L2 can be fed from a first label feeding part 21 or a second label feeding part 22 to a label seaming part 23, so that one label roll is seamed by the other label roll automatically. The device is provided with an upstream side label bolding roller 30 and a downstream side label holding roller 31, an upstream side drive roller 32, a vacuum drive roller 33 capable of feeding seaming labels L3, a first end detecting sensor 26, a second end detecting sensor 27, a seaming part end detecting sensor 34, and a label loosening part 25.
