Abstract: Folder systems and related methods are provided for accurately and efficiently folding a paper carrier that has a card attached without bending or dislodging the card from the carrier. A movable fold chute receives a portion of the carrier with the card attached and allows the carrier to fold while protecting the card portion of the carrier. The fold chute moves between different positions which allow the carrier to enter and exit through folding rollers along a generally straight paper path without forcing the cards around small radii, thereby preventing damage to the cards or causing them to separate from the carrier sheet.
