1. Assembly for fabrication of pellets from a powder material comprising:
a powder distributor, a table provided with cavities, on which the distributor is capable of moving, said powder distributor comprising a casing comprising a cover provided with means connecting it to at least one powder supply conduit connected to a hopper, two side walls and two end walls, said distributor being capable of moving the powder in a to and fro movement on a plane along a determined displacement direction (X), said assembly comprising means of guiding the distributor along the displacement direction and means of pressing the distributor in contact with the table, in which said guide means comprise at least two guide rollers installed on each side wall, said guide rollers having rotation axes (Z) perpendicular to a plane of the table, said guide rollers cooperating with a guide running track fixed relative to the table, and in which said pressure means comprise at least two pressure rollers on each side wall, said pressure rollers having rotation axes (Y1) perpendicular to the displacement direction (X) and parallel to the plane of the table, each pressure roller cooperating with a pressure running track fixed relative to the table, said pressure rollers being arranged only between the associated pressure running track and the table, and being capable of moving to and fro relative to the pressure running track, such that the pressure force is increased by moving the pressure rollers towards the associated pressure running track. |
