ABSTRACT:
To join the start of a new web to an expiring web a splicing assembly is provided which includes a light source and photoelectric cell. When a splice is to be effected, the splicer is moved towards the new reel and when the light beam is interrupted by the periphery of the reel the splicer is stopped in the correct position for splicing, and the position of the cell used as an indication of the diameter of the reel; a signal from the cell also causing the reel to be driven at such a speed that the speed of the new reel matches the linear speed of the old web so that the splice may be effected properly.
