The device for conditioning preforms in plastic material comprises a rotating turret (20), having a group of conditioning cavities (22) for inserting preforms, partly through an opening on a first side (A) of the turret and partly through an opening on a second side (B) of the turret. The conditioni
The device for conditioning preforms in plastic material comprises a rotating turret (20), having a group of conditioning cavities (22) for inserting preforms, partly through an opening on a first side (A) of the turret and partly through an opening on a second side (B) of the turret. The conditioning cavities (22) which open on the first side (A) are disposed in such a way that for part of their length (L1) they are situated side by side with the cavities which open on the second side (B). In this way the turret becomes more compact. There is also described a conditioning method for the preforms.

The invention claimed is: 1. A device for conditioning of objects in plastic material, having a length, comprising: a rotating turret comprising two opposing sides that include a first side and a second side, wherein the first side and the second side of the rotating turret face in opposite directions; and a group of conditioning cavities, each conditioning cavity having a length and being provided with a respective opening for the insertion of said objects, said group of conditioning cavities comprising first and second conditioning cavities, wherein the openings of the first conditioning cavities are located on the first side of the rotating turret, and the openings of the second conditioning cavities are located on the second side of the turret, such that the openings of the first conditioning cavities and the openings of the second conditioning cavities face in opposite directions, the first conditioning cavities being located in such a way as to be side by side with the second conditioning cavities for at least part of their own length. 2. A device as claimed in claim 1, wherein the turret comprises a box-like structure including an external casing and each conditioning cavity is enclosed in a respective individual casing contained in turn inside the box-like structure. 3. A device as claimed in claim 2, wherein the individual casings are designed to contain a conditioning fluid for the conditioning cavities. 4. A device as claimed in claim 2, wherein the box-like structure contains at least a conditioning fluid circulation circuit acting operationally on the conditioning cavities. 5. A device as claimed in claim 4, wherein the first conditioning cavities are adjacent on both sides, following the directions of lines and columns, with one of second cavities. 6. A device as claimed in claim 3 or 5, comprising means for rotating the turret at least around the rotational axis so as to turn each time said first or said second side toward a predetermined reference direction. 7. A device as claimed in claim 6 wherein the means for rotating are intended to translate the turret in order to vary the alignment of the conditioning cavities. 8. Moulding equipment for plastic objects, including a conditioning device according to claim 1. 9. Moulding equipment according to claim 8, further comprising means for tilting said turret so as to turn each time said first side or said second side upwards or downwards. 10. A method of conditioning a plurality of moulded objects in plastic material, comprising: arranging a first side of a conditioning device according to claim 1 turned upwards; introducing the rotating turret in the middle of the two open halves of a warm forming mould; transferring at least one group of moulded objects, resulting from a press operation, from said mould in which they have been formed, to said rotating turret so as to refill at least a part of said conditioning cavities of said first side; extracting the rotating turret from the two said open halves of the mould tilting the rotating turret so that said second side is turned upwards. 11. A method as claimed in claim 10, comprising: reintroducing at least a second time the rotating turret into the middle of the two open halves of said mould; transferring at least a second group of moulded objects, resulting from a successive pressing cycle, from the mould in which they have been formed, to said rotating turret so as to refill at least a part of the conditioning cavities of said second side of the turret.
