Apparatus for the production of hinge-lid packs for cigarettes

In an apparatus for producing hinge-lid packs, especially for cigarettes, from a pack blank which is foldable around a cigarette block during transport by rotating folding turrets, said pack blanks together with said cigarette block each being held in pockets of a folding turret and being foldable by means of folding members of fixed location connected to said folding turret, non-folded pack blanks (12) being conveyable up to said folding turret (35), the improvement comprising at least one blank track (43, 44) for conveying the non-folded pack blanks (12) to said folding turret (35) in a direction tangential thereto until they come to rest against a pocket bottom (48) of a pocket (47).

In an apparatus for producing hinge-lid packs, especially for cigarettes, from a pack blank which is foldable around a cigarette block during transport by folding turrets, the improvement for providing a two-track mode of operation, wherein each folding turret (35, 36) is a double turret comprising two identical turret discs (85, 86) arranged on a common turret shaft (87).

In an apparatus for producing hinge-lid packs, especially for cigarettes, from a pack blank which is foldable around a cigarette block during transport by folding turrets, said pack blanks together with said cigarette block each being held in pockets of a folding turret and being foldable by means of folding members of fixed location connected to said folding turret, the improvement comprising:

• means for putting the cigarette block (11) in a position, ready for being packed, resting against a pack blank (12) of a pocket (47) in the region of an introduction station (54);
• and guide means for holding said cigarette block in said position while being transported further by the folding turret (35), said guide means being of fixed location extending over part of the circumference of said folding turret (35), and said guide means comprising an arcuate outer holder (61, 75) which has a corotating holding band (62) and a holding strand (65) resting against an outwardly facing side of said cigarette block (11).

In an apparatus for producing hinge-lid packs, especially for cigarettes, from a pack blank which is foldable around a cigarette block during transport by circular folding turrets, said pack blanks together with said cigarette block each being held in pockets of a circular folding turret, the improvement comprising spring means (96, 98) for elastically shifting the pockets (47, 74) of the folding turret (35, 36) in the radial direction, a pocket bottom (48) of each pocket being supported on said spring means.

In an apparatus for producing hinge-lid packs, especially for cigarettes, from a pack blank which is foldable around a cigarette block during transport by folding turrets, said pack blanks together with said cigarette block each being held in pockets of a holding turret and being foldable by means of folding members of fixed location connected to said folding turret, each pocket having a pocket bottom, the improvement comprising:

• first and second successive folding turrets;
• means for transferring a partially folded hinge-lid pack (10) in the first folding turret (35) to the second folding turret (36) by causing the hinge-lid pack to come up against the pocket bottom (48) of a pocket (74) of the second folding turret, the distance between the pocket bottoms (48) in the region of a transfer station (69) corresponding approximately to the dimension of the hinge-lid pack (10);
• and means for contrarotatingly driving the two successive folding turrets (35, 36) so that said folding turrets (35, 36) continuously rotate during transfer of the partially folded hinge-lid pack (10) in the transfer station (69).
