摘要:
A device for feeding blanks on a cigarette packing machine, wherein a succession of blanks, arranged side by side and overlapping one another along a supporting strip wound into a reel, is fed along a supply path by unwinding the reel and feeding the supporting strip along the path, which extends through a pitch-change device for spacing the blanks to eliminate the overlapping arrangement, and for adjusting the pitch of the blanks in a given manner.
摘要:
A method and device for feeding sheet material, whereby the sheet material is fed in a given traveling direction along one face of a plate by a fluid bed movable along the face in the traveling direction; the fluid bed being formed by at least one jet of fluid, which is directed in a direction substantially tangent to the face and concordant with the traveling direction, and is fed inside a window formed through the plate.

At a certain stage in the fabrication of a rigid cigarette packet, which appears essentially as a rectangular cup or body with a coaxial lid, the partly formed packet is transferred from a first feed path onto a second feed path, still having longitudinal flaps that project on either side from a front face of the body and a front face of the lid; the transfer is effected by means of a device that includes in a rotatable platform with at least one gripper head designed to engage at least the two front faces of the single packet in such a way that the body and lid remain stably interconnected, and during the course of the transfer movement to rotate the packet through 90.degree. about an axis which is normal to the front faces.
摘要:
A unit for supplying layers of cigarettes, wherein a supply outlet, presenting an open bottom end and a number of channels converging towards the bottom end, feeds a succession of layers of cigarettes along the channels to the bottom end; and an extracting device is associated with the outlet to expel the layers one by one in an extraction direction parallel to the cigarettes in the layer and on to a fixed pickup plate presenting a bottom surface for releasably retaining the cigarettes in a single layer.

In a machine (1) for manufacturing pouches (2) filled with portions (36) of a tobacco mixture, comprising a rotating drum (8) on which a continuous stream (5) of the mixture is formed and conveyed to a station (13) where the portions (36) are divided from the stream, and where the portions (36) are transferred by a pneumatic ejection and feed system (21) to a wrapping station (7), moisturizing substances are added to the mixture by a dispensing system (22) associated with the ejection and feed system (21).

摘要:
Pouches (2) of cohesionless material, typically a smokeless tobacco product, are manufactured by conveying portions of the tobacco initially on a dispensing disc (5a) with cavities (7) from a delivery station (8) to a transfer station (9), where each portion of tobacco is then removed forcibly from the relative cavity by an ejection system (14) and directed into a duct (12) connecting with a wrapping station (10) at which the pouches (2) are formed, filled and sealed; the removal and transfer of each portion from the cavity (7) of the disc (5a) into the duct (12) is controlled in such a way as to displace the material by degrees and ensure its smooth passage toward the wrapping station.
摘要:
A container (1) for food products is fashioned in such a way that there are no interstitial spaces or stagnation traps on the inside. The bottom end (8) of the container is fashioned by bending and flattening one end portion (7) of a tubular blank in such a way as to produce two triangular stiffening folds (10) of double thickness, each penetrable along one open side coinciding with the base (10a) of the triangle; before the folds (10) are turned inward, the open sides are sealed by bonding the two triangular thicknesses together along the base (10a) so that the folds remain isolated from the inside of the container (1).
摘要:
A duct (1) applicable to a container (4) presents a connecting portion (9) with four substantially flat connecting surfaces (9a) and a internal bridging surface (13) by which the side walls (7a) of the container (4) are joined seamlessly to a spout (5) afforded by the duct (1); the bridging surface (13) is contoured in such a way that a flow of liquid food product can be directed through the spout (5) without becoming trapped and stagnating between the duct (1) and side walls (7a) of the container (4).
