Total Claims: 6
Claim 1
Independent Claim
70 words
Machine as claimed in claim 1, characterized by the fact that the said hollow pyramid has a square base, two of its opposite faces belonging to two movable members moving in the direction of the axis passing by the middle of the sides constituting the basis of these two faces, means permitting to produce the simultaneous displacement of the said movable members towards the center or in the opposite direction.
Claim 2
Dependent Claim
67 words
Machine as claimed in claim 2, characterized by the fact that the means controlling the two movable members of the support are constituted by a screw rotatably mounted on the frame of the machine, prevented from moving axially, provided with two opposite threaded portions threaded into two opposite threaded nuts, carried the first one by one of the movable members and the second one by the other.
