ABSTRACT:
A method and apparatus are provided for forming a zero tail length splice between a new roll of web material (26) and an expiring roll (24) without interrupting continuous movement of the web (W). The method includes providing a splicing strip (60) adhesively secured to the leading edge (62) of the new roll (26) and releaseably secured to the surface of the new row (26) so that it can be rotated without unwinding until it is spliced to the moving web (W) of the expiring roll (24), placing a marker (80) on the circumference of the new roll (26), which marker (80) is located a predetermined distance ahead of the leading edge (62) of the new roll in a position to be sensed by a sensing device (162), as the roll (26) is rotated adjacent the moving web (W), sensing the location of the new roll (26) relative to the surface of the moving web (W) as it is brought into close proximity with the moving web (W) and stopping its movement so that the roll (26) is held in the desired position just above the surface of the moving web (W), bringing the new roll (26) up to a rotational speed so that its surface speed matches the surface speed of the moving web (W), forcing the moving web (W) into engagement with the rotating new roll (26) at the point of closest proximity therebetween after the leading edge on the new roll (26) has passed the point of closest proximity as determined by the sensing device (162), noting the passing of the marker (80), and then further activating a cutting means (102) upon the second passing of the marker (80), for severing the moving web (W) at a distance equal to the distance along the circumference of the new roll (26) from the leading edge (62) to the point of closest proximity between the new roll (26) and the moving web (W) so that substantially a zero tail length splice is formed when the splicing strip (60) adhesively engages the surface of the moving web (W) adjacent the tail end (168) thereof.
