    摘要: Automatic splicing apparatus includes a first supply containing a first web (a1) and a second supply containing a second web (a2). An operable puller (4) is engaged with the first web (a1) for intermittently withdrawing the same from the first supply and moving the first web along a predetermined path in a periodic manner. Cutters (12,12') are provided for establishing a trailing end on the first web and a leading end (Q) on the second web (a2), cutting each web midway of a lenghtwise repeated pattern. The presence of the trailing end in the predetermined path is detected and a splicing station (10) is positioned in the path for butt-splicing the leading edge (Q) of the second web (a2) to the trailing end of the first web (a1) in response to detecting the presence of the trailing edge. The splicing is effected with maintained during one of the dwell periods of the first web without interrupting the step by step operation of the puller (4).
