Zusammenfassung:	A drive system is configured to feed a sheet material. The drive system includes a first roller and a second roller. A circumference of the first roller has a first curved profile. A circumference of the second roller has a second curved profile. The first and second rollers are arranged such that, when the sheet material is not located between the first and second rollers, the first curved profile of the first roller contacts the second curved profile of the second roller. The first and second rollers are further arranged such that, when the sheet material is located between the first and second rollers, rotation of at least one of the first and second rollers causes the sheet material to be fed through the drive system.
