Abstract
A method and device for splicing a rotating new roll of material to a moving web which is nearly exhausted, each web having uniformly spaced indicia thereon and wherein the indicia on the new roll at the leading end thereof is unevenly spaced, the speed of the old web being adjusted to correspond with the peripheral speed of the new roll during a portion of its periphery and the indicia then being exactly registered along that portion so that the webs are spliced together to provide a continuing web having uniformly spaced indicia thereon.
