Stacking of plies of rubber compound

A method for stacking a ply which is transferred from a rubber mixing system to a stacking system, the method comprising the steps:

• transferring the ply to a stacking head of the stacking system;
• passing the ply to a motorized belt of the stacking system, the motorized belt being able to turn in both directions and being able to move in translation, and the motorized belt being situated between the stacking head and a pallet;
• and
• setting the motorized belt into movement in translation by turning the motorized belt in a first direction so as to move along a path such that the motorized belt is placed in a position to receive the ply from the stacking head at the same time as the stacking head continues to pass the ply to the motorized belt, and stopping the motorized belt from turning at the same time as the stacking head continues to pass the ply, making a downstream end of the ply to be stacked accessible in order to connect it to an upstream end of a ply of a successive pallet and form a butt joint between the plies,
• wherein the stacking head has two alternating motorized belts, and each one turns in a predetermined direction at the same time as each one pivots about its axis of rotation along a preset contour.
