ABSTRACT:
A method and apparatus for providing or maintaining accurate register of a web with mechanisms operating on the web. The web is driven substantially without slippage at a first position on the web path and a register roller is positioned at a second position on the web path. The register rollers and web are caused to engage without substantial slipping relative to each other. The web is driven at the first position and by the register roller at speeds which have a substantially constant ratio to one another so that web elongation therebetween is substantially constant.
