Abstract: A machine for coating magnetic tape uses a method of replacing a running out foil band by a new foil band, where, shortly before running out, and without interrupting a continuous run, a new roller is moved in the winding machine and accelerated to replace the nearly used roller. Subsequently the bands of both rollers are joined together without altering their speed. Ultimately the end piece of the band of the nearly empty roller is cut off and the tension of the new band adjusted and the empty roller stopped. The new band roller (9) is, during its rotation through less than 360 deg. from stand still, accelerated to 90% - 98% of the speed of the running out foil band (2) and when both the bands (2, 9) are joined together, the acceleration is stopped and the tension of the new band is adjusted without subjecting it to shocks.
