glazed'paper, etc., or for anymaterial printed or embossed with a raised mark at regular: intervalsgthis object is achieved by making I V roller against the driven roller to intermit use of the difiter'enceintliickness andfric- :0 length being pulled back by suitablemeansf tion between the printed and unprinted portions of the strip, the strip beingjstopped by a brake fingerengaging with its printed surface. The strip feed is so arrangedthata section of the strip somewhat longer than required for one package is advancedat each cycle of the packaging machine, the excess :until stoppedbythe aforesaid brake finger;

The retracting meansreferred to preferably consists of a resilient take-up arm which pushes a portion'of the strip out of alignment, the said portion being limited by a? suitable guide, but may be devisedin any other manner.
