Material sheet guiding system for a thermoforming machine

A material sheet guiding system of a thermoforming machine for guiding a material sheet, the material sheet guiding system comprising:

• a pair of longitudinal rail members disposed in a spaced parallel relation to one another, each of the pair of longitudinal rail members having a first set of wheels and a second set of wheels disposed longitudinally between a first end portion and a second end portion of the each of the pair of longitudinal rail members along a length thereof, wherein each wheel of the first set of wheels configures a nip arrangement with a corresponding wheel of the second set of wheels;
• and
• a drive unit operatively coupled to the first set of wheels of the each of the pair of longitudinal rail members to rotate the first set of wheels for moving the material sheet from the first end portion to the second end portion through the nip arrangement.
