ABSTRACT:
Apparatus for transporting a material web having lateral depressions (25, 27) arranged at regular distances from one another. For the transport of a material web (10, 35) of this type in the correct position, the web bears on a conveying drum (28) which has elevations (29, 30) for positive penetration into the depressions (25, 27). In a material web (10, 35) consisting of partially prepunched blanks (11), the conveying drum (28) serves, in cooperation with an auxilary drum (51), for forming bending points (49, 50), the material web (10, 35) being capable of being grasped by suction bores (52, 53), offset relative to one another in the circumferential direction, of the conveying drum (28), on the one hand, and of the auxiliary drum (51), on the other hand.
