1. A machine for packaging groups of products in a wrapping sheet, comprising
a device for spreading a wrapping sheet; and
a 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 support from below flaps of the wrapping sheet which protrude from a group of products supported on the handling device and act on a surface of the wrapping sheet facing the products to be packaged.
