Abstract
A transport device for multiple layered web material consists of a transport roll and a pressure roll between which the web material passes. The pressure roll is in the form of a hollow prism mounted with play on a supporting shaft. The interior of the prism has rounded corners with a radius of curvature matching that of the shaft. During rotation of the pressure roll, the transport roll translates with the web material during some portions of its movement and rotates relative to the shaft during other portions of its movement.
