ABSTRACT:
The machine comprises a main carousel including a horizontal axis having seats which are angularly equidistant and open outwardly and including at the front a gripper and at the rear a folding device. Each seat passes first adjustable means with the gripper open to supply the gripper with a packaging sheet arranged on the seat, and cooperating with a first auxiliary carousel which inserts a roll into each seat, oriented with its axis parallel to that of the main carousel, while the roll is partially wrapped with the packaging sheet retained by the closed gripper. In succession, the rear folding device intervenes and the gripper opens and folding means intervene in order to fold the front edge of the sheet onto the rear edge, while the folding device returns to the rest position and the edges are fixed together by a heat-sealing carousel. The seats then pass opposite the folding devices which fold and arrange on one another several end portions of the tubular sheet and then the packaged roll is unloaded by a second auxiliary carousel which transfers it to downstream conveying means for heat-sealing the end folds of the package.
