摘要:
Process and device for applying print marks to an article that includes conveying the article along a transport direction at a predetermined conveyor speed, during a printing procedure, reducing a relative speed between a printing element and the article conveyed along the transport direction, and applying print marks to the article by the printing element. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
摘要:
Method and printing mechanism for applying print marks on an article. The method includes conveying a tobacco processing industry article along a transport direction at a predetermined conveying speed, and applying the print mark to the tobacco processing industry article via at least one ink jet printer cartridge. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
摘要:
The invention concerns a perforating apparatus for producing openings in a peripheral surface of a substantially elongate, cylindrical object, in particular a cigarette, comprising a light source for producing at least one high-energy light beam, by means of which the openings can be produced in the object, an operative zone which can be produced by a guidance tracking means for guided tracking of the light beam and within which the light beam acts on an object moving through the operative zone, to produce the openings, rolling means for producing a rotary movement of the objects about their longitudinal axis while the objects are moving through the operative zone in order to expose the peripheral surface to the light beam, and transport means for conveying the object through the operative zone. The invention is characterised by a light-refracting means through which the light beam is passed before reaching the operative zone so that upon guided tracking of the light beam the light beam remains focused substantially everywhere within the operative zone.
摘要:
An elongated strip of tipping paper is advanced in a tipping machine for the making of filter cigarettes. The strip advances past a perforating unit and thereupon past a cutting unit which subdivides the perforated strip into a series of uniting bands ready to be convoluted around abutting ends of plain cigarettes and filter rod sections. One side of the strip is coated with a film of an adhesive which can be inactivated by exposing it to coherent radiation. The perforating and cutting steps are carried out by one or two beams of coherent radiation which can further serve to inactivate the adhesive around each perforation and along the edges which extend across the strip to thus reduce the likelihood of penetration of active adhesive into the perforations and/or a contamination of the products by active adhesive being expelled beyond the marginal portions of the uniting bands. A single source can suffice to furnish coherent radiation for the carrying out of the perforating, cutting and inactivating operations.
摘要:
A running web of tipping paper (one side of which is coated with a film of adhesive) in a filter cigarette making machine is subdivided into discrete uniting bands and/or is perforated by resorting to a single source or to two discrete sources of coherent radiation. Each source is associated with a control unit which initiates the emission of short-lasting flashes of coherent radiation. Such radiation is caused to impinge upon a diffractive focusing lens which focuses coherent radiation upon one or more masks having openings for coherent radiation which is to sever the web along transversely extending linear zones and/or to provide the web with desired arrays of perforations. The perforations permit atmospheric air to enter the column of tobacco smoke in a filter cigarette wherein the tobacco-containing portion and the filter mouthpiece are united by a perforated adhesive-coated uniting band.

摘要:
Adhesive-coated bands of paper, tipping paper or plastic foil are convoluted around discrete one-piece or composite rod-shaped articles, such as coaxial plain cigarettes and filter mouthpieces, during travel through a rolling zone bounded by a pair of surfaces at least one of which moves relative to the other. The inlet of the rolling zone receives articles, each of which carries a non-convoluted band, from a conveyor which forms part of a pressing device operative immediately ahead of the inlet of the rolling zone and serving to press successively delivered bands against the respective articles and to effect an at least slight flattening of the articles immediately prior to entry into the rolling zone. The width of the path for the articles increases at the outlet of the rolling zone or immediately downstream of such outlet.
摘要:
A magazine for rod-shaped articles comprises a storage unit having at least one inlet for receiving at least one of the articles supplied to the storage unit and at least one outlet for discharging at least one of the articles positioned in the storage unit. A variable length belt element disposed in the storage unit has a length which defines a fixed storage unit for accommodating a predetermined number of articles. The length of the belt element is expandable for defining a working storage unit, the volume of which can be changed with the expansion of the belt element.

A module for a machine used in the tobacco processing industry for processing, assembling, and/or inspecting rod-shaped articles. The machine module includes a vertical conveyor.
摘要:
An apparatus for increasing the permeability of tubular wrappers of a succession of cigarettes by at least one pulsed beam of coherent radiation issuing from a laser has a hollow drum-shaped conveyor cooperating with a rolling member to define an arcuate channel wherein successive cigarettes roll while advancing sideways past a perforating station. Each beam of coherent radiation is generated in or is caused to enter the interior of the conveyor prior to being influenced by one or more deflecting and/or focussing elements to be propagated substantially radially and through an opening of the hollow conveyor and to impinge upon the wrapper of a cigarette rolling at the perforating station.
