ALIGNMENT AND TRANSPORT ROLL MADE OF FLEXIBLE MATERIAL

摘要

An alignment and transport roll made of flexible material has a curved cross-section and comprises a ring-like thicker outer circumferential part. An item to be transported is deflected in an alignment direction by the outer part. Upon rotation of the roll or movement of the paper the item is aligned and transported. The alignment force is generated in one and the same direction regardless of the direction of movement of the item. The roll can also be provided with a supporting structure on one side to avoid alignment in the wrong direction when the roll flips over by deflection in the wrong direction. Roll and supporting structure or roll per se can be joint in a pair of rollers coacting with each other. Roll or roller pair can be used in any alignment unit. It is preferably used in a passbook for printer to align the passbook for printing purposes and for reading the magnetic stripe on the passbook. The roll is versatile enough to cope with thinner and thicker material. It also can be used for aligning and transporting continuous forms. As flexible material for the roll castable plastic material like polyurethane with a hardness of 60 Shore A may be used.
