Abstract
Abstract For transporting a paper web an endless belt is provided running about spaced apart pulleys. Several ball or roll clamping devices are mounted on the belt to extend within the path of the belt so that the web gripping portions travel in a smaller path than the belt and hence on the curved end path about the pulleys they travel at a lower speed than the belt.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
100 words
Transport device for web-like material, particularly for paper webs in high-speed printers of data processing systems, where an endless belt driven over pulleys is used, characterized in that the axles (7,8) of the pulleys (5,6) are substantially vertical to the plane of the web (1), and that on the belt (3) ball or roll clamping devices (4) acting in transport direction (2) are provided and arranged in such a manner that during its working cycle the belt (3) travels a greater distance (3'') than the clamping points (9'') of the ball or roll clamping devices (4) with the web (1).
Claim 2
Dependent Claim
100 words
