Abstract
A system for dispensing individual sheet material segments from a roll of sheet material. The sheet material is separated into individual segments by perforated tear lines which are shaped to incrementally pass through a nip formed by nip rollers due to a pulling force exerted on an end-most segment by a user. A drag force opposed to the pulling force is exerted on the sheet material by the nip rollers so that the tear line tears as it passes through the nip. Tearing along the perforated tear line is not completed until a portion of an adjacent segment is presented for pulling by a subsequent user.
