Abstract
A wrapping device in which two rotating drums (18, 20) of identical circumferential velocities are arranged symmetrically and one of the rotating drums (18) is provided around its circumference with a number of recesses (36) adapted to receive the sheet articles from an open bottom (32) of the hopper (16) in which a number of the sheet articles are stored in superposition whereas the opposite rotating drum (20) is provided around its circumference with a number of receivers (78) which first hold the wrapping paper and then catch the sheet article transmitted from the rotating drum (18), so that the wrapping operation is continuously performed by the synchronous rotation of the wrapping drums (18, 20) with folding of the wrapping paper.
