    Abstract: An interfolding apparatus including a knife roll, a first interfolding roll, a second interfolding roll, and a transfer roll. The knife roll cuts sheets from a stream of web material issuing from a source in a downstream direction. The first interfolding roll is positioned downstream of the knife roll and receives the sheets. The first interfolding roll rotates in a first direction and the second interfolding roll rotates in a second direction. The first and second interfolding rolls interfold the sheets with additional sheets received by the second interfolding roll. A transfer roll is positioned between the knife roll and the first interfolding roll. The transfer roll has a non-uniform surface configuration and rotates in the second direction and receives the sheets from the knife roll, forms a bend in each of the sheets, and transfers the formed sheets to the first interfolding roll.
