Abstract
A frictional drag arrangement for a sheet material dispenser tensions the withdrawn sheet material during each withdrawal, particularly when the sheet material supply is almost completely removed from its supporting roll. The arrangement includes leaf springs mounted within stub shafts that are insertable into the supporting roll. The leaf springs exert drag forces on the material.
