ABSTRACT:
There is disclosed an apparatus for feeding an elongate sheet material comprising a drive roller driven to rotate at a constant speed, a pressure roller rotatable in rolling contact with the drive roller, the drive roller being formed of a more resilient material than the pressure roller, the pressure roller when biased against the drive roller deforms the peripheral surface of the drive roller in contact with the elongate sheet material sandwiched between said rollers. Provision is made for changing the force of contact between said drive and pressure rollers, whereby the peripheral surface of the drive roller is varied in size thereby changing the peripheral speed of said drive roller and the speed of travel of the elongate sheet material.
