Claims.
1) Automatizing machine for loading-unloading operations of the skeins with double wringing and overturning in continuous cycle, characterized by the fact that a first squeezing assembly (5) is foreseen with a robot device- (6) for upturning the hanks another squeezing- ssembly (7) and an automatizing device consisting of a charging robot (8) which takes away the hanks (2) with the relevant sticks (23 and 24) from the preparation unit (4) and lays than down on the arm (12) of the drying device.

2) Automatizing machine for loading-unloading operations of the skeins with, double wringing and overturning in continuous cycle, as per claim

1 , characterized by the fact that the sticks on which the skeins (2) are hanging, are laid down on the transporting chain (3) of the prepa-ration machine (4) , which chain with its continuous motion carries the sticks and hanks to the first squeezing assembly (5) consisting of a pair of squeezing cylinders, where the hanks are partially squeezed.
Sticks and hanks reach then the automatic device (6) which upturns the skeins and shifts one stick at a time (23 and 24) on which the hanks groups are suspended, allowing their complete rotation and, consequent ly, their upt_urning. The hank part (25) which was leaning on the sticks and had not been squeezed during the first phase, is now in an opposite position to the sticks and, therefore, is squeezed in the subsequent phase by the squeezing assembly (7) . A complete and uniform squeezing of the hanks is therefore performed.

3) Automatizing machine for loading-unloading operations of the skeins with double wringing and overturning in continuous cycle, as per claim

2, characterized by the fact that the hanks upturning device (6) takes away one stick (24) after the first upturning, whereas the second stick

(23) is transported by the chain (3) and advances_ The first stick (24) is again laid down on the chain (3) , while the second stick, in its turn.

is taken away by the pliers by the robot mechanism (6) ; when the first stick (24) is in vertical correspondence with the second above one (23) , the robot mechanism (6) lays down one stick (23) on the other

(24) , thus- allowing the hanks upturning and transfer of the not squeez_ ed (25) from below-to above, i.e. from the part opposite to the sticks. In the sebsequent squeezing phase, this allows to treat also the part (25) still wet frcm the previous squeezing phase due to the presence - of the supporting sticks (23 and 24) .

4) Automatizing machine for loading-unloading operations of the skeins with double wringing and overturning in continuous cycle, as per claim 2, characterized by the fact that after the end of the squeezing phases, the two sticks (23 and 24) supporting the skeins are separated to one from the other and, consequently, the skein inside is widened thus facilitating the introduction of the drying device arm (12) . The same loading robot (8) transfers and charges the skeins on arm (12) by lift. ing a stick (23) , by a side shifting the other stick (24) , by transferr - ing the hanks on arm (12) , by lowering the two sticks (23 and 24) to facilitate their removal from the skeins, by taking them away and by their fall into the collecting container (14) .

5) Automatizing machine for loading-unloading operations of the skeins with double wringing and ove__txιrning in continuous cycle, as per claim 1 , characterized by the fact that the squeezing assemblies (5 and 7) can be driven by means of pneumatic, oildynamic and mechanical systems.
