摘要:
A cigarette comprising a tobacco rod comprising a tobacco filler and a cigarette paper which is wrapped around the tobacco filler, a filter comprising a filter member and a filter wrapping paper which is integrally wrapped around the filter member, and a tipping member which is bonded onto the tobacco rod and the filter with a pressure-sensitive adhesive to connect the tobacco rod and the filter.

Immobilized diluents in a smoking article are provided, wherein diluents can be immobilized through absorption and/or adsorption of the diluents into immobilizing materials, such as sorbents like silica gels. By immobilizing diluents, the diluents can be available for vaporization, while still being protected from migration and/or loss of the diluents in a smoking article.
摘要:
Method and device for determining a quantity or mass of glue applied to a wrapping strip of the tobacco-processing industry, machine including the device and process. The method includes acting on the wrapping strip with ultrasound waves, receiving the ultrasound waves permeating through the wrapping strip as ultrasonic signals, and determining at least one of a quantity or mass of glue based on the ultrasonic signals received.
摘要:
A paster which serves to apply a film of adhesive material to the underside of a running web of flexible material, such as tipping paper in a filter cigarette maker, has a roller which supplies successive increments of the film to the underside of the running web and cooperates with a biasing device which rides on the web and urges certain portions of the underside of the web against the roller. The length of the area of contact between the biasing device and the upper side of the running web is less than the width of the web. This renders it possible to prevent or to minimize undesirable flow of adhesive laterally beyond the marginal zones of the web as well as into perforations which are customarily provided in webs of tipping paper.
摘要:
An applicator head, for applying a coating of material (e.g. hot-melt adhesive) to a passing ribbon comprises an extrusion slot disposed transverse to the direction of passage of the ribbon and arranged to apply a coating of material in at least one continuous band along the ribbon, and an arrangement for intermittently opening and closing an extrusion slot for applying a coating of material discontinuously in a band contiguous with said one band.

A gummer for a filter attachment machine comprises two rollers (10, 12), one of which is arranged to contact the web and the other of which is pressed against the first roller to limit the quantity of gum which is transmitted to the web from a pool of gum formed in the nip between the rollers. Gum is fed continuously into the pool at a position between the ends of the rollers at a rate in excess of the rate at which gum is applied to the web, from which position the gum flows towards the ends of the rollers. Means (15, 16, 50) are provided for collecting excess gum at the ends of the rollers and for returning it to a source (19) of the gum.
摘要:
The applicator roll is provided with two recesses to apply uniform layers of glue to a travelling stream of tipping paper. In addition, the applicator roll has a series of spaced apart grooves in each recess so as to apply additional stripes of glue onto the tipping paper near the edges. The additional stripes of glue provide for a more secure bonding of the tipping paper to the tobacco column of the filter cigarette construction.

A cigarette tipping material having non-lipsticking properties includes preselected areas of the tipping material provided with non-lipsticking coatings with other preselected uncoated areas having perforations therein.
摘要:
This disclosure involves periodically bumping webs such as a cigarette filter paper or the like against a shear surface disposed beyond a multi-nozzle adhesive extruder to provide longitudinally intermittent bands of adhesive coatings for the filters or the like, with optional provision for continuous marginal lines of adhesive along and between the bands for adhesion on the head and tail ends of such filters or other articles as well.
摘要:
A filter is formed by placing increments of glue in spaced apart relation on a moving stream of plug wrap paper and thereafter depositing alternating fibrous filter sections on the glue increments. Particulate material is then deposited between the fibrous filter sections and the plug wrap paper wrapped about the filter sections to form an endless rod. Two-filter filter plugs are severed from the rod by cutting through the unglued fibrous filter section and thereafter the charges of particulate filter material are compacted by moving the unglued outer filter sections of each plug inwardly. Each plug is then joined to two tobacco columns and cut in half. The resultant filters each have a fibrous filter section at the exposed end glued to the plug wrap paper, a compacted particulate section and an unglued fibrous filter section at the tobacco end.
