Abstract
A method and apparatus are provided for preparing discrete blanks from a wound strip comprising a plurality of connected blanks. Each blank has a determined separation point and a marker at a determined distance from the determined separation point for making soft-type wrappers. First, the wound strip is unwound under tension. Next, at least a section of a particular blank of the unwound strip is cut and any other milling and preparatory steps are performed by appropriate rollers and mechanisms. The tension of the unwound strip is slackened periodically, e.g., via chocking these rollers, and the unwound strip is realigned relative to the marker of the particular blank during this slackening, e.g, by identifying the marker via a sensor and driving the strip via rollers. The particular blank of the realigned strip is separated at the determined separation point of the particular blank to separate the particular blank from the realigned strip.
