One or several fabric loops are disposed along the running route of a web of paper. The loops are driven via reversing rollers normally belonging to the paper machine. Air blowers extending along the running route of the fabric loops are disposed so that air jets blown through them support the tail of the web of paper and press it toward the fabric that drives the tail forward in connection with different parts of the machine, such as the calender and other rollers. An additional roller is provided as a continuation of the reversing roller and is provided with a magnetic clutch for connecting and disconnecting it as needed.
