摘要:
A product wrapping machine comprises feed means by which products to be wrapped are directed on entry, in ordered succession, to a take-up station, a wrapping device comprising a first conveyor, rotatable continuously about a respective axis and a second conveyor rotatable intermittently about a respective axis, and a transfer device by which the products are gripped in succession at the take-up station and fed to the wrapping device. The first conveyor comprises a plurality of carriers, mounted rotatably on it and equipped with gripper heads. Each carrier is associated with a respective motion-inducing device designed to move the carrier in such a way as to enable the carrier to interface and interact with a respective gripper element of the second conveyor.

On a packing machine, pockets on a conveyor are fed in steps through a transfer station; and at least one product is transferred to/from a pocket on the conveyor when the pocket is arrested at the transfer station during a pause between two successive steps; before the product is transferred, the pocket is moved with respect to the conveyor to set the pocket to a given transfer position at the transfer station.

A method for making a hinge-lid pack of cigarettes, which finds particular application in the manufacture of a pack with rounded or beveled vertical edges having retention means to facilitate consistent lid closure, comprises: positioning an inner frame on a bundle of cigarettes; folding a first end of a blank for a hinge-lid cigarette pack over one end of the bundle of cigarettes to at least partially form the lid of the pack; and moving the inner frame relative to the blank in the direction of the at least partially formed lid. Apparatus for making a hinge-lid pack of cigarettes by folding a blank for a hinge-lid cigarette pack about a bundle of cigarettes having an inner frame thereon, includes means for forming a portion of the blank into the lid of the pack, the apparatus further comprises means for moving the inner frame relative to the blank towards the at least partially formed lid. Preferably, the apparatus comprises a wheel indexable between a number of stations, the wheel having a plurality of pockets spaced about its periphery.

A folding method and device, whereby a tubular wrapping is formed about a product by inserting the product inside a U-shaped pocket together with a sheet of wrapping material, a first lateral portion of which is interposed between the product and a first lateral wall of the pocket, and a second lateral portion of which, opposite the first, is folded outside and beyond the pocket and crosswise to the first lateral portion; the tubular wrapping being closed by moving the first lateral wall of the pocket outwards, simultaneously moving a contrast member onto the first lateral portion, and then folding the second lateral portion, by means of an external folding member, onto the product and so as to overlap the first lateral portion; and the tubular wrapping being fixed inside the pocket by withdrawing the external folding member, simultaneously closing the first lateral wall onto the product, and withdrawing the contrast member (34) from the pocket.

A machine for wrapping groups of products (7) in tubular lengths of stretch film (4) comprises a rotating carousel (1) equipped with a plurality of wrapping units (2) having bars (3) for holding and stretching to size a succession of tubular film lengths (4) fed to a station (S1) and for placing the stretched tubular film lengths (4) around respective groups of products (7) to be wrapped fed one after the other.
摘要:
In a wrapping apparatus, particularly for enclosing articles consisting of or containing groups of cigarettes in wrapper material, the articles are received in a pocketed drum in which at least one overlapped region of the wrapper material is heat scaled. Preferably opposed side seams and an end flap of the wrapper are sealed, so as substantially to complete the enclosure of the article while on the drum. Side seal heaters carried by the drum may be mounted on respective annular carriers which are rotatably displaceable to remove the heaters from contact with the articles if the drum is stopped for an extended period. End seal heaters may be pivotally mounted on the drum and operated by a cam arrangement to fold an end flap of the wrapper into an overlapped position.

Packets are overwrapped in a cellophaner unit equipped with a wheel by which the packets are directed through an assembly station together with leaves of wrapping material and toward a folding station where the leaves are bent around the packets, also a suction roller set in rotation continuously and tangentially to the wheel, on which the leaves are held by suction while advancing along a first path extending between a cutter device and the assembly station; the wheel is furnished with peripheral carriers supporting the single packets, each equipped with gripper jaws positioned to take up one end of a leaf held on the adjacent roller and detach it by degrees from the relative suction surface before effecting an initial overwrapping step of folding the leaf partly around a relative packet.
摘要:
A wrapper folding apparatus of a packaging machine has a second wheel (10) for use as a folding turret. The second wheel (10) is supplied with a cigarette bundle and an aluminized sheet (S) in an inlet position. As this is done, the aluminized sheet (S) is folded around the periphery of the cigarette bundle, and lug portions formed by the peripheral folding are folded by the use of primary lug folding guides (36). Since the lug protions are kept folded by the use of holding guides (38) thereafter, they cannot be freed until an outlet position is reached. When the cigarette bundle is discharged in the outlet position of the second wheel (10), the lug portions on the end-flap side are folded by the use of secondary lug folding guides (46). After the folding, side flaps continue to be folded without allowing the lug portions to be free.
