Abstract
Successive cigarette packs wherein an inner envelope surrounds an array of smokers' products are advanced against successive foremost blanks of a series of blanks to be converted into outer envelopes of the respective packs. Those portions of the inner envelopes which are secured to each other by an adhesive are mechanically held against separaton prior to complete setting of the adhesive on their way toward the blanks, during entrainment and initial deformation of the blanks and, if necessary, during conversion of the blanks into outer envelopes which surround the respective inner envelopes. The blanks can consist of a light transmitting material.
