Abstract

Cette invention concerne une moissonneuse dans laquelle des corps rotatifs sans fin (55) peuvent facilement être ajustés sur une paire adjacente de dispositifs de saisie/transport (45, 45) de sorte que chaque corps rotatif sans fin se trouve dans le même état de tension. La moissonneuse comporte les éléments suivants : un support mobile (84) sur lequel repose un corps de roue rotatif (52) autour duquel tourne l'extrémité de transport du corps rotatif sans fin (55) de l'un des dispositifs de saisie/transport (45) et un corps de roue rotatif (52) autour duquel tourne l'extrémité de transport du corps rotatif sans fin (55) de l'autre dispositif de saisie/transport (45), lesdits dispositifs de saisie/transport (45, 45) étant adjacents dans le sens de la largeur de la moissonneuse de sorte que les trajets de retour (59) des corps rotatifs sans fin (55) se trouvent face à face; un support fixe (82) sur lequel pivote le support mobile (84); et un système de mise sous tension (85) qui peut fonctionner de manière à déplacer le support mobile (84) par rapport au support fixe (82) dans le sens où la tension s'exerce sur les corps rotatifs sans fin (55) par l'intermédiaire des corps de roue rotatifs (52).
