Claim 7:
8. A machine for packaging groups of products in a wrapping sheet, comprising:
a device for spreading a wrapping sheet;
a handling device adapted to move a group of products to be packaged and the wrapping sheet with respect to one another to wrap the wrapping sheet around the group of products due to reciprocal movement between the wrapping sheet and the group of products; wherein the handling device comprises an elevator provided with a lifting and lowering movement;
temporary support members adapted to support flaps of the wrapping sheet protruding from the group of products during a phase of the 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 the surface of the wrapping sheet from below the wrapping sheet; and
wherein the temporary support members are provided with a lifting and lowering movement synchronized with an initial phase of movement of the elevator as the elevator moves toward the wrapping sheet, and during the initial phase of said movement, the flaps of the wrapping sheet projecting laterally from the group of products are supported by said temporary support members.
