Abstract
A device is provided for transferring nuclear fuel element sheaths to a fixed pellet filling station. This device comprises a sheath transfer assembly. This latter comprises a first transporter for taking as a whole a layer of several sheaths placed on the laying rack of the first means associated with the first transporter and intended for changing the spacing pitch of the sheaths in the layer and for presenting the layer at the position for simultaneous filling of several sheaths by the vibrating table machine (50) for inserting fuel pellets, second pitch change means for bringing the sheaths back to the original pitch, a transporter cooperating with a second pitch change means for bringing the layer of sheaths as a whole onto a take up rack and means for the automatic synchronized control of the components of the assembly ensuring the movements of the sheaths always in the same direction.
