ABSTRACT:
A driving head for a line cutter device includes a base part; a spool driver; mounting means for mounting a spool, on the spool driver; and a set of teeth circumferentially distributed on the spool driver. An operating member is connected to the base part and having oppositely a first and a second end and a first detent at the first end and a second detent at the second end, the detents being adapted for cooperating selectively with one of the teeth of the set of teeth on the spool driver, the first end being heavier than the second end. Biasing means biases the operating member. The biasing means is such that when the operating member is rotated faster than a predetermined rotational speed the centrifugal force of the operating member acting on the biasing means causes it to be counteracted to disengage the second detent from the tooth with which it is engaged thereby allowing slippage between the operating member and the spool driver so that an increment of line is fed out from a spool mounted in the driving head and bringing the first detent into cooperation with a tooth of the set of teeth.
