<p>A housing (a) supports a reel (b) surrounded by a casing (c). The reel core (1) extends into a shaft (3) sliding in a bush (2) integral with casing (c) and supported by a second guide (3'), enabling the shaft to slide freely. A pinion (4) at the base of bush (2) engages in the teeth of a crown wheel (5) located on the perimeter of a disc (6) keyed to a shaft (7) connected to the winding handle. On the front surface of disc (6) is a spiral channel (9) whose ends are connected by a short closing section. A runner (10) sliding in the channel is connected by peg (11) to shaft (3). When disc (6) is turned by the winding handle, the runner follows the channel to transform this movement into a reciprocating shaft movement which is transmitted to reel (6) which is being rotated by crown wheel (5) and pinion (4).</p> |
