Abstract

A machine wherein block-shaped arrays of cigarettes are confined in envelopes having closed ends and open ends located at the adjacent end faces of the confined arrays. Each open end includes two confronting elongated flaps alternating with narrow tucks which are to be folded against the adjacent end face of the confined array ahead of the flaps. Successive envelopes are delivered onto a platform constituting the bottom wall of a receptacle and being movable from a lower level, in which the receptacle receives an envelope, to an upper level in which it delivers the finished envelope into a pocket at the underside of an indelible turntable. The tucks of an envelope on the platform are folded over the adjacent end face of the confined array by two folding elements which are movable in a horizontal plane. The flaps are held against deformation by mobile confining elements and the upper panel of the envelope adjacent the upper flap is held against bulging by a pivotable back support which overlies the envelope adjacent its open end during folding of the tucks.
