Abstract:
A machine for making sub-units of smoking articles comprises a conveyor, a feed unit, cutting means and at least one rotary applicator. The conveyor is configured to feed a succession of tubular segments of the tobacco industry. The feed unit is configured to feed and convey at least one continuous web. The cutting means are configured to separate a succession of closing elements from a front end of the continuous web. The rotary applicator is operatively associated with the conveyor and is configured to pick up the succession of closing elements and to apply them, preferably by gluing, to an application end of a respective tubular segment, in such a way as to form closing walls to at least partly close the application ends.
Abstract:
A sub-unit of a smoking article includes a tubular wrapper which extends along a main axis of extension and internally defines a containment chamber containing a filling material of the tobacco industry. The tubular wrapper has an access opening on at least one of its ends for access to the containment chamber. The sub-unit also includes at least one closing element applied to the at least one end of the tubular wrapper to define a closing wall for closing the access opening. The closing element extends transversely to the main axis of extension in such a way as to at least partly close the access opening.
Abstract:
A food-safe paper straw, including an outer tubular element made of paper material which extends along a longitudinal axis and a longitudinal insert made of paper material positioned inside the outer tubular element and stably connected to an inner surface of the outer tubular element, said insert having a profile, in transversal cross section, defined by a line at least partly corrugated and/or partly broken in such a way as to increase the bending strength of the straw, wherein said insert is stably connected to the inner surface of the outer tubular element in at least two connecting zones, preferably at least three connecting zones, angularly spaced from each other about said longitudinal axis.
Abstract:
A machine for making a continuous tubular element with filling from web material, including first and second means for feeding respective continuous webs, a forming station configured to perform a folding and/or deformation of a first continuous web in a shaped configuration, and a wrapping station wherein the second continuous web is wound in a tubular shape around the first continuous shaped web to obtain the continuous tubular element. Between the forming station and the wrapping station there is at least one guide bar about which the first continuous web is at least partly formed and/or guided.
Abstract:
This invention relates to a method for crimping a web of material for the tobacco industry, including the following steps: feeding a web of material for the tobacco industry along a feed path; crimping the web between two crimping rollers operatively coupled to make a plurality of longitudinal easy folding lines on the web; measuring a value of a thickness of the web before the step of crimping; The step of crimping the web is adjusted as a function of the thickness value measured during the step of measuring.

Abstract:
A machine for making sub-units of smoking articles includes a conveyor, a feed unit and an applicator. The conveyor conveys a succession of tubular segments transversely along a conveying direction. The feed unit feeds and conveys a continuous web and advances the web along a feed direction parallel to the conveying direction of the tubular segments so that the web faces respective application ends of the tubular segments. The applicator is movable along an application direction parallel to an axis of predominant extension of the succession of tubular segments and is configured to engage the web so as to separate respective closing elements from it. The applicator is also configured to apply the closing element internally or externally on an application end of a respective tubular segment in such a way as to form a closing wall to at least partly close the application end.
Abstract:
A machine for making cigarette filters and which includes a forming beam having an internal channel whose transverse cross section changes shape along the main longitudinal direction of the channel. Porous conveyor means carry the tow along a feed path in the channel complying with the shape thereof and thereby being wrapped around the tow. At least one treatment station located along the feed path includes a nozzle for blowing a flow of steam into the channel. The nozzle includes a plurality of planar sectors positioned transversely to the channel and defining an overall planar flow orifice placed directly in communication with a steam feed duct. Each planar sector defines a respective planar flow orifice and at least two flow orifices have different thicknesses.
Abstract:
A feeder device of products with reduced longitudinal dimensions in machines for the tobacco industry comprises a main feeder roller which rotates continuously and which has a plurality of active peripheral flutes acting to hold a respective product; the main roller is designed to pass the products on to respective flutes on corresponding handling rollers of a main line of feed of the products in the machine the device is associated with; the device comprises means for continuously filling the peripheral flutes of the main roller, the filling means comprising a plurality of feeding and passing-on means, in particular at least first means and second means for feeding and passing on corresponding groups of the products to corresponding groups of flutes located one after the other on the main roller.
