Method of forming a stack of interfolded sheets of web
First Claim
1. A method of forming a stack of interfolded sheets of web material, the method comprising:
- rotating first and second interfolding rolls;
issuing a stream of interfolded web material from the first and second interfolding rolls;
forming a stack of interfolded web material;
moving a first packer finger with respect to the first interfolding roll between a retracted position at least partially received within the first interfolding roll and an extended position at least partially inserted into the stream of interfolded web material; and
moving a second packer finger with respect to the first interfolding roll between a retracted position at least partially received within the first interfolding roll and an extended position at least partially inserted into the stream of interfolded web material,the first packer finger and the second packer finger alternating to both contact each interfolded sheet in the stream of interfolded web material issued from the first interfolding roll.

Abstract
An interfolding apparatus including first and second interfolding rolls. The interfolding rolls issue a stream of web material to form a stack of interfolded web material. A first packer finger is movable with respect to the first interfolding roll and includes a retracted position at least partially received within the first interfolding roll and an extended position at least partially inserted into the stream of interfolded web material. A second packer finger is movable with respect to the first interfolding roll and includes a retracted position at least partially received within the first interfolding roll and an extended position at least partially inserted into the stream of interfolded web material.

10. A method of forming a stack of interfolded sheets of web material, the method comprising:
-
rotating a first interfolding roll; conveying a first sheet of web material with the first interfolding roll; rotating a second interfolding roll; conveying a second sheet of web material with the second interfolding roll; interfolding the sheets to form a stack of interfolded sheets; contacting the first sheet with the second sheet; at least one of retracting two packer fingers at least partially into the first interfolding roll and retracting an additional two packer fingers at least partially into the second interfolding roll; altemating the two packer fingers to each contact the first sheet; and alternating the additional two packer fingers to each contact the second sheet. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
