The system (1) is equipped with a feed station (7) supplying a forming material (9), a scoring station (18) by which crease lines (4a) are generated, and a cutting station (19), combining to prepare a succession of blanks (4). The system (1) also includes a prefolding station (21) where each blank (4) is bent initially along the creases lines (4a), a folding station (24) where the single blank (4) is fashioned to the shape of the container (5), and a sealing or welding station (26) at which the shape of the container (5) is fixed definitively.

Abstract: Packets of cigarettes with a predominating longitudinal axis, presenting two larger side faces, two smaller flank faces and two end faces, are overwrapped by a unit incorporating a first conveyor rotatable about a relative axis, on which a sheet of transparent film is folded initially around the side and flank faces of each packet by one of a set of peripheral holder mechanisms pivotable about respective axes parallel to the axis of the conveyor. Each holder mechanism supports a relative packet, gripped between a pair of jaws and disposed with the longitudinal axis parallel to the axis of the conveyor, and comprises a clip serving to grip and retain one end of the sheet, operating in conjunction with suction holes by which the remaining free end of the sheet is attracted and restrained and thus kept perfectly under control during the transfer of the packet to a second conveyor that will complete the initial overwrapping step.

Abstract: A curling device for a filter tip attachment comprises at least one blade-like element offered to a continuous strip of paper material at a selected contact zone in such a way as to deform the material as it advances, so that single tipping papers separated from the strip by a cutting unit of the attachment are given a curved profile and as a result more easily wrapped around and affixed to the assembled filters and cigarette sticks when these are joined together; the curling device also comprises a delivery system by which the contact zone is flooded with a cushioning fluid designed to favor a smooth sliding contact between the curling element and the running strip, and at the same time equalize the tensions in the strip preceding and following the contact zone.

Abstract: On an apparatus for electrochemical precision machining, the tool holder (1) performing the oscillatory motion is supported by bearing bushes (25, 26) made of a swelling material within a casing (2) performing the feed motion. The swelling, cooling and lubricating liquid is supplied from liquid chambers (4, 5) provided in the casing. A further liquid chamber (6) prevents electrolyte from ingressing into the bearing bushes. The linear oscillatory motion of the tool holder is generated by a rocker (33) which is arranged vertically to the tool holder, extends through the casing and is driven by the eccentric (30) of a drive motor (29) with an associated frequency converter. A measuring device (42) and a fastener (43) enable the tool holder to be locked in a defined position, this permitting the apparatus to be operated with high accuracy also in the non-oscillating mode of the electrode.

Abstract: Cigarette sticks are transferred from a cigarette maker to a filter tip attachment by a unit that includes a conveying roller made to rotate in a first feed direction and furnished with channels aligned on a second direction transverse to the first direction. Each channel accommodates a single stick, directed onto the conveying roller by way of an impeller device, and presents two longitudinal areas designed to make contact progressively with corresponding longitudinal areas of the stick as it advances into the channel, the effect being to create a chamber between the stick and the part of the channel lying between the two longitudinal areas of contact, which is connected to a source of negative pressure.
