Method of packing of pet preforms and a die for packing pet preforms

摘要

The method of packing of PET preforms and a die for packing PET preforms are the object of the invention. The method of packing PET preforms is characterised by the fact that the die is provided with groups of cavities of the same amount and or comparable depth that are simultaneously filled up with the same of preforms in such an arrangement that the upper parts of the lower preforms are in contact with the bottom of the upper preforms, and when the specified level of the packing is reached, the next groups of cavities of the same depth are filled up, and then, the activity is repeated with regard to the next group of cavities of the same depth. The die for packing PET preforms is characterised by the fact that the die is provided with groups of cavities (u2/u), (u3/u) and (u4/u) of the identical outline, whose geometrical centres intersect at alpha angle of 60 DEG , and each of the groups (u2/u), (u3/u) and (u4/u) has different depth and each internal cavity (u2/u) preferably borders on three cavities (u3/u) and on three cavities (u4/u), and each internal cavity (u3/u) preferably borders on three cavities (u2/u) and on three cavities (u4/u) and each internal cavity (u4/u) preferably borders on three cavities (u2/u) and on three cavities (u3/u).
