Classification: CPC B | IPC B

Claim 6:
7. A machine for packaging groups of products in a wrapping sheet, comprising
a device for spreading a wrapping sheet; and
handling device adapted to move a group of products to be packaged and the wrapping sheet with respect to one another, thus wrapping the wrapping sheet around the group of products due to a reciprocal movement between the wrapping sheet and the group of products; and
temporary support members adapted to support flaps of the wrapping sheet protruding from the group of products during a phase of reciprocal movement between the group of products to be packaged and the wrapping sheet;
wherein the temporary support members comprise mechanical members adapted to act on a surface of the wrapping sheet facing the products to be packaged,
wherein the handling device comprises an elevator provided with a lifting and lowering movement with respect to the wrapping sheet,
wherein the temporary support members are provided with a lifting and lowering movement synchronized with the movement of the elevator,
wherein the support members are controlled to perform a stroke synchronized with an initial phase of the movement in which the elevator moves toward the wrapping sheet, the stroke of the support members being shorter than the stroke performed by the elevator, with respect to the wrapping sheet.
