1. A motor-driven conveying roll for conveying containers in a conveying system, comprising:
- a hollow roller body having inner and outer circumferences;
means for rotatably mounting said roller body in a conveying frame;
a drive unit which is mounted within said roller body, said drive unit being non-rotatable relative to said conveying frame and having an output shaft; and
a pressure-exerting unit, said output shaft of said drive unit being frictionally connected to said inner circumference of said roller body by means of said pressure-exerting unit;
wherein said pressure-exerting unit has first and second disks defining on an outer circumference thereof a V-shape, into which an elastic pressing ring is placable.
