An apparatus for feeding pasta sheet into a pasta-making machine, includes a feed device for feeding a strip of pasta sheet along a predetermined path, and a punching device designed to operate on the strip in the stop condition so as to punch the strip and obtain from the strip cut pieces of pasta sheet intended to be wrapped around respective portions of filling, thereby producing respective pieces of filled pasta. The apparatus includes a speed variator device for the feed speed of the strip, interposed between the feed device and the punching device for causing, during each machine cycle of the apparatus, a variation in the speed of a branch of the strip positioned at the punching device which, in combination with the speed at which the strip is supplied by the feed device, stops the branch of the strip.

A method for producing bags containing fiber material, comprises the steps of forming at least one continuous layer of fiber material; separating in succession portions of fiber material from the continuous layer and moving them along a predetermined path; feeding each portion of fiber material to respective containment and compaction elements of a first transfer conveyor; feeding an ordered succession of bags containing respective portions of fiber material to respective supporting elements of a second transfer conveyor; transferring the portions of fiber material inside respective containment bags carried by the second transfer conveyor; transferring the containment bags from the second transfer conveyor to a fourth transfer conveyor; and moving in succession the bags housing respective portions of fiber material to a folding unit at which the bags are closed.

A cigarette packet includes a container containing a group of cigarettes and provided with an opening defining a zone giving access to the group of cigarettes. The container includes a covering element movable between a closed position and an open position which allows access to the zone giving access to the group of cigarettes. The packet includes a mirroring element located at the access zone and having a mirroring surface at least at one portion of it, and the covering element has at least one graphic sign at least at one portion of an inside surface. The portion of the inside surface is taken, when the packet is opened, to a condition where it substantially faces the mirroring surface, such that the graphic sign is reflected on the mirroring surface and is visible to a smoker.

A cigarette packet substantially having the shape of a parallelepiped and containing a group of cigarettes includes an outer case formed by two larger lateral walls, respectively a front wall and a rear wall, and by two smaller lateral walls or sides, by a lower wall or base and by an upper wall or lid. An inner case is inserted in the outer case. The outer case includes a projection for controlling the lid, the projection being interposed between the front wall of the outer case and a front wall of the inner case and moveable between a first position in which the lid is closed and a second position in which the lid is open. A mechanism is provided for reciprocal engagement of the projection and the inner case for partially extracting the group of cigarettes from the outer case.

Tobacco products are wrapped by a unit equipped with a rotating drum carrying a set of holder mechanisms around the periphery, each rotatable about an axis parallel to the axis of the drum, by which single products are supported and carried through an assembly station together with leaves of wrapping material received from a vacuum roller turning on an axis parallel to the axis of the drum; the vacuum roller revolves tangentially to the drum at the assembly station and comprises a system by which each leaf is transferred to a gripper associated with the support mechanism. The transfer system is timed to operate in a situation of substantially zero relative peripheral velocity between the support mechanism and the vacuum roller.

Strip material used in packaging machines is fed by equipment comprising a rotary support unit carrying at least one roll of a first strip material or a second strip material, installed downstream of a feed unit supplying a first wrapping material along a first direction toward an operating station where inner wrappers are fashioned for the particular packet in production. The first strip material is decoiled by rollers and guided along the first direction to an operating station of the machine where coupons are prepared for inclusion as inserts, placed between the inner wrapper and an outer wrapper of each packet. The second strip material is taken up and diverted by further rollers along a second direction, in such a way that it can be supplied to an operating station of a cellophaner where it is cut and folded to fashion leaflets applied as onserts to the outer wrapper of each packet before being overwrapped.
摘要:
A method of manufacturing composite filters for cigarettes, cigars and similar tobacco products, on a twin track machine, involves generating a succession of filter sticks of a first type, made from a first filter material and/or having first filtration properties, and at least one other succession of filter sticks of a different type, made from a respective different filter material and/or having filtration properties different to those of the first type; cross-cutting the filter sticks of the first type and the filter sticks of the different type on at least one transverse cutting line to obtain a succession of first and second plugs of the first type and a succession of first and second plugs of the different type; arranging the first plugs of the first type and the first plugs of the different type in alternation one with another to create a first filter rod, and arranging the second plugs of the first type and the second plugs of the different type in alternation one with another to create a second filter rod; checking the position of at least one first plug of the first rod, relative to a corresponding second plug of the second rod; and correcting the position of the at least one transverse cutting line according to the relative positioning of the first and second plugs.
摘要:
A method of gumming a web of paper material in a filter tip attachment machine is implemented using a gumming device that comprises a gumming roller and a transfer roller counter-rotating tangentially one to another about horizontal and parallel axes, and creating a trough in which to hold a prescribed quantity of adhesive supplied by a feed circuit, also a drive system by which the rollers are set in rotation on their axes, and a control unit to which both the feed circuit and the drive system are interlocked. The gumming roller revolves tangentially to the web of material at a gumming station, and the method envisages a procedure, triggered in the event of a stoppage affecting the machine, that consists in the steps of suspending delivery of the adhesive, distancing the web of paper material from the gumming roller, and reversing the direction of rotation of the rollers, relative to the direction of rotation during normal operation, in such a way that the trough is emptied gradually of adhesive.
摘要:
Groups of cigarettes approaching a packer are transferred and inspected by a conveyor equipped with receptacles advancing along a set path, and an inspection device such as will verify the presence and the integrity of each cigarette in each receptacle and generate signals to indicate the outcome of the inspection. The conveyor also incorporates emitters in the form of permanent magnets, each associated with a relative receptacle and interacting with a receiver consisting in an array of magnetoresistors ordered along the conveying path; the receiver is capable of emitting signals synchronized with the steps of the inspection procedure and indicating the position of each receptacle relative to a fixed inspection position.
