Paper 10, which may have printed matter on it, is wound onto core 11 supported between fixed rotatable drive flange 12 and longitudinally movable pressure flange 13 supported by frame 14 with a bias spring 15. Core 11 is shorter than the width of paper 10. Cradle 16 loosely supports the supply roll l7 maintained in alignment with the take-up mechanism by longitudinally movable flange 18 and bias spring 19 against end plate 20. Supply roll 17, when full, has a diameter such that when supported in cradle 16, it interferes between drive flange 12 and adjustable flange 13. With this arrangement the flanges 12 and 13 are automatically spaced to conform to the width of the paper 10.
