摘要:
A method and unit for forming a tobacco bead, whereby a forming conveyor conveying the tobacco bead cooperates with a pressing device for compacting portions of the tobacco bead equally spaced with a given spacing, and cooperates with a shaving device; and whereby a distance between the pressing device and the forming conveyor is regulated independently of a distance between the shaving device and the forming conveyor, and as a function of a linear travelling speed of the forming conveyor or a physical quantity related to it.
摘要:
A wrapping method for producing soft packets presenting an inner packet and an outer wrapping,whereby each inner packet is fed into a respective seat on a wrapping conveyor at a transfer station and together with a sheet of gummed wrapping material which is folded in a U about the inner packet; the sheet of wrapping material being subjected to a number of folding operations to form a tubular wrapping about the inner packet and to axially close the tubular wrapping by folding one end of it; and the folding operations being performed as the seat travels a minimum number of steps from the transfer station.
摘要:
A continuous strip of sheet paper material is divided into blanks by a device comprising a cutter and an anvil rendered capable of sliding movement one in relation to the other and establishing a cutting position toward which the strip is advanced by way of a passage incorporated into the anvil; the cutter is reciprocated across the anvil in such a manner as to pass through the cutting position transversely to the strip, alternating between two limit positions on opposite sides of the passage, the geometry being such that the cutter will vacate the passage entirely when occupying either one of the two limit positions.
摘要:
A unit for wrapping packets, wherein a first seat, carried on a first conveyor, closed by a sheet of wrapping material and housing a packet, is brought into engagement with a second seat on a second conveyor to insert the packet inside the second seat and fold the sheet into a U about the packet; the first seat engaging a respective packet by the end surfaces of the packet; and the second seat engaging the packet by a pair of lateral walls crosswise to the end surfaces.
摘要:
A device for the orderly supply of cigarettes; the device presenting at least one channel defined by two lateral walls and for feeding a respective column of cigarettes at a given dropdown speed and in a given traveling direction to the bottom opening of the channel; and an ordering device being provided upstream from the bottom opening in the traveling direction, and presenting at least two engaging elements located at either end of one of the two lateral walls and movable inside the channel to accompany the cigarettes along a given portion of the channel and so feed the cigarettes in orderly manner to the bottom end.
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 unit for forming and wrapping groups of cigarettes, whereby cigarettes are fed, crosswise to their respective axes, onto a supporting surface to form, on the supporting surface, a multilayer group located between two opposite retaining heads of a pocket for conveying the group; the two retaining heads leave a lateral surface of the group substantially free, and feed the group along the supporting surface, and crosswise to the respective axes of the cigarettes, through a supply line for supplying sheets of wrapping material.
摘要:
A pocket element for a packing wheel for packing groups of cigarettes in rigid packets with a hinged lid; each packet being formed by folding a precut blank; and the pocket element presenting a seat having a pair of locating elements, each having an oblique surface for supporting respective edges of a respective pair of end tabs of the blank defining a small longitudinal wall of the lid of a respective packet.
摘要:
A device for removing, from a reel of strip material, an adhesive tape secured to a peripheral surface portion of the reel via thermoplastic adhesive material; which device comprises a pair of rollers supporting the reel; one of the rollers being a drive roller for rotating the reel about its axis; at least one heating element located close to the peripheral surface of the reel and designed to substantially contact the tape; and the other roller having vacuum openings for removing the tape from the peripheral surface of the reel subsequent to the adhesive material being plasticized by the heating element.
摘要:
A method of replacing a first strip having equally-spaced preprinted graphics with a second identical strip on a manufacturing machine having an input traction unit for feeding the first strip along a first route defined by a first and second branch forming a given angle; the second strip, after being accelerated along the first branch and adjusted in relation to the first strip, being cut and fed on to the second branch by a spoon-shaped guide plate operating in a direction substantially coincident with that of the second branch.
