Patent No. EP2371749 (titled "Multi-Path Interfolding Apparatus And Method") was filed by Cgbretting Manufacturing on Jan 23, 2009. The application was issued on Jun 19, 2019.
Multi-path interfolding apparatus for producing interfolded towels of different lengths and patterns without replacing components. The apparatus has two sheet-cutting-and-overlapping arrangements and an interfolding arrangement in a common frame. The first arrangement cuts shorter sheets and the second arrangement cuts longer sheets. Both arrangements feed sheets to the interfolding arrangement to make interfolded stacks of the same width. The interfolding rolls rotate at the same speed. This allows switching between 3-panel and 4-panel towels without changing overlap speeds or cutting rolls.

Patent oppositions filed by competitors challenge the validity of a granted patent. These oppositions are typically based on claims of prior art, lack of novelty, or non-obviousness. They are a key part of the process for determining a patent's strength and enforceability.
