Abstract
A printer is provided with a single drive shaft mounted on plural bearings and carrying a plurality of axially aligned, individually rotatable, hollow friction rolls, each containing an electromagnetic brake and a coupling for connecting the roll to the shaft. The electromagnets are operated independently for the several rolls and feelers are disposed upstream of the paper webs to operate the brake when sensing a marking or the end of a roll of paper separately for each roll.
