Abstract
On a housing (10) which has a mount (20) for a roll (22) of paper, a roller (30) is mounted, by means of a spindle body (32), beneath said mount. A spring (40) is wound in the form of a coil around the spindle body (32) and, in the event of forwards rotation of the roller (30), is subjected to stressing and rotates said roller into a rest position after the paper web (24) has been severed. An end section (42, 48) of the spring (40) is formed by spring coils which always rest against the spindle body (32) in a close-fitting manner, with the result that they act as a directional lock. Between its end sections (42, 48), the spring (40) has a main part (46) comprising spring coils which, in the non-stressed state, enclose the spindle body (32) with radial spacing, only rest against the spindle body (32) in a close-fitting manner after a predetermined forwards rotation of the roller (30), and consequently prevent further rotation of the roller (30). This means that a paper web (24) of predetermined length can be drawn off the roll (22) via the roller (30). The drawn-off paper length can then be severed from the paper web (24) by means of a severing device (50).
