Definitions
- the present invention relates to a method of producing filter-tipped cigarettes.
- an output of a cigarette manufacturing machine is connected to an input of a production line of a filter assembly machine; and the input is supplied with a succession of "double" cigarette portions, i.e. portions twice the length of the portion which, joined by a band to a respective filter, forms a normal filter-tipped cigarette.
- the double cigarette portions are cut transversely into half to form pairs of single portions, each pair of which is parted axially and separated by inserting a double filter to form, from each double portion, a group defined by two single portions and a double filter.
- Each group is formed into a so-called "double cigarette” by winding a band about the double filter and part of the single portions as the group is fed along an intermediate rolling portion of the production line.
- Each band is fed to the intermediate rolling portion so that the leading longitudinal edge of the band contacts the respective group, and so that the band initially projects rearwards of the respective group, which must therefore be separated from the following group by a distance at least equal to the width of the band.
- Each band is normally wound about the respective double filter by rolling each group along a rolling surface, and each double cigarette so formed is fed to an output portion of the production line, along which each double cigarette is cut in half to form two opposed filter-tipped cigarettes, one of which is normally turned over to form a single succession of equioriented filter-tipped cigarettes.
- the rolling operation is particularly critical by possibly resulting, if performed over and above a given maximum speed, in tobacco fallout from the open ends of the single portions, and/or in tearing of the paper on the outside of the single portions.
- One such step provides for feeding the double portions along the input portion of the production line by means of rollers for retaining the double portions inside closely spaced peripheral suction seats - in particular, inside seats equally spaced along the periphery of the rollers with a spacing normally equal to half the width of the double cigarette bands; and the rolling portion is formed as already known from US Patent 4,745,932, i.e. by means of two parallel, superimposed rolling branches, each of which receives alternate groups from the input portion of the production line, so that the groups fed along each rolling branch are arranged with twice the spacing as along the input portion, and can therefore safely receive the respective bands.
- feeding the bands by means of two feed devices located on the same side of the production line necessarily means feeding the material from one of the feed devices across the production line, which is unacceptable.
- a method of producing filter-tipped cigarettes comprising the steps of feeding double cigarette portions into respective seats on a feed roller of an input portion of a filter-tipped cigarette production line; cutting said double portions transversely, along said input portion, to form pairs of coaxial single portions; axially parting said single portions along said input portion; inserting a double filter between each pair of coaxial single portions along said input portion to form a group of three coaxial elements; feeding a band to each said group by means of two feed devices located on the same side of said production line; and connecting each said double filter to the single portions of the respective group by means of the respective said band along a rolling portion of said production line defined by a first and a second rolling branch located parallel to each other, with said second branch interposed between said first branch and said feed devices; characterized in that said double portions are arranged along the periphery of said feed roller in pairs of adjacent double portions to form, along said input portion, pairs of adjacent said groups; said pairs of adjacent double portions being equally spaced along
- the above spacing of the double portions on the feed roller is particularly advantageous by enabling, as in US Patent 5,715,838, the feed roller to accommodate substantially twice the number of double portions which would be permitted by the band assembly operation. Unlike US Patent 5,715,838, however, the above arrangement in pairs of adjacent double portions enables at least one of the double portions in each pair - in particular, the double portion downstream in the rotation direction of the feed roller - to receive the respective band even before reaching the rolling portion of the production line.
- a first said band is supplied by a first of said two feed devices to a first group in said pair of groups, as the first group is fed along said input portion; and a second said band is supplied by a second of said two feed devices to a second group in said pair of groups, as the second group is fed along said rolling portion; said first group being located downstream from said second group with respect to a traveling direction of said groups along said production line.
- each said first group is fed along said first branch of the rolling portion of said production line, and each said second group is fed along said second branch of the rolling portion of said production line; each said second band being supplied to the respective said second group as the second group is fed along said second rolling branch.
- the present invention also relates to a machine for producing filter-tipped cigarettes.
- a machine for producing filter-tipped cigarettes comprising a filter-tipped cigarette production line in turn comprising an input portion and a rolling portion; said input portion comprising a feed roller having a number of peripheral seats, supply means for feeding a succession of double portions into said seats, cutting means for cutting said double portions transversely into pairs of coaxial single portions, each said pair of single portions being housed inside a respective said seat, parting means for axially parting the single portions in each said pair of single portions; a supply device for inserting a double filter between the single portions in each said pair of single portions to form a respective group of three coaxial elements; said rolling portion comprising a first and a second rolling branch parallel to each other; two feed devices being provided on the same side of said production line to supply a band to each said group; and said second branch being interposed between said first branch and said feed devices; characterized in that said seats are arranged along the periphery of said feed roller in pairs of adjacent seats to form pairs of adjacent said groups

Description
- The present invention relates to a method of producing filter-tipped cigarettes.
- In one known method of producing filter-tipped cigarettes, an output of a cigarette manufacturing machine is connected to an input of a production line of a filter assembly machine; and the input is supplied with a succession of "double" cigarette portions, i.e. portions twice the length of the portion which, joined by a band to a respective filter, forms a normal filter-tipped cigarette.
- On the filter assembly machine and along an input portion of the production line, the double cigarette portions are cut transversely into half to form pairs of single portions, each pair of which is parted axially and separated by inserting a double filter to form, from each double portion, a group defined by two single portions and a double filter. Each group is formed into a so-called "double cigarette" by winding a band about the double filter and part of the single portions as the group is fed along an intermediate rolling portion of the production line.
- Each band is fed to the intermediate rolling portion so that the leading longitudinal edge of the band contacts the respective group, and so that the band initially projects rearwards of the respective group, which must therefore be separated from the following group by a distance at least equal to the width of the band. Each band is normally wound about the respective double filter by rolling each group along a rolling surface, and each double cigarette so formed is fed to an output portion of the production line, along which each double cigarette is cut in half to form two opposed filter-tipped cigarettes, one of which is normally turned over to form a single succession of equioriented filter-tipped cigarettes.
- Of all the above operations, the rolling operation is particularly critical by possibly resulting, if performed over and above a given maximum speed, in tobacco fallout from the open ends of the single portions, and/or in tearing of the paper on the outside of the single portions.
- Since the rotation speed of the single portions during the rolling operation depends directly on the traveling speed of the single portions along the rolling surface, various steps are taken to reduce the speed at which the single portions are fed onto the rolling surface and, hence, the rotation speed of the single portions during the rolling operation.
- One such step, described, for example, in US Patent 5,715,838, provides for feeding the double portions along the input portion of the production line by means of rollers for retaining the double portions inside closely spaced peripheral suction seats - in particular, inside seats equally spaced along the periphery of the rollers with a spacing normally equal to half the width of the double cigarette bands; and the rolling portion is formed as already known from US Patent 4,745,932, i.e. by means of two parallel, superimposed rolling branches, each of which receives alternate groups from the input portion of the production line, so that the groups fed along each rolling branch are arranged with twice the spacing as along the input portion, and can therefore safely receive the respective bands.
- The provision described in US Patent 5,715,838 involves several drawbacks, foremost of which is the necessity to feed the bands to the respective groups as the groups are fed along the respective rolling branches, and using two distinct feed devices, which must be located on the same side of the production line - in particular, over the production line, for reasons of material supply and the position in height of the production line itself.
- In the case of US Patent 5,715,838, feeding the bands by means of two feed devices located on the same side of the production line necessarily means feeding the material from one of the feed devices across the production line, which is unacceptable.
- It is an object of the present invention to provide a method of producing filter-tipped cigarettes, which is straightforward and cheap to implement and, at the same time, is reliable and designed to eliminate the aforementioned drawback.
- According to the present invention, there is provided a method of producing filter-tipped cigarettes, comprising the steps of feeding double cigarette portions into respective seats on a feed roller of an input portion of a filter-tipped cigarette production line; cutting said double portions transversely, along said input portion, to form pairs of coaxial single portions; axially parting said single portions along said input portion; inserting a double filter between each pair of coaxial single portions along said input portion to form a group of three coaxial elements; feeding a band to each said group by means of two feed devices located on the same side of said production line; and connecting each said double filter to the single portions of the respective group by means of the respective said band along a rolling portion of said production line defined by a first and a second rolling branch located parallel to each other, with said second branch interposed between said first branch and said feed devices; characterized in that said double portions are arranged along the periphery of said feed roller in pairs of adjacent double portions to form, along said input portion, pairs of adjacent said groups; said pairs of adjacent double portions being equally spaced along the periphery of the feed roller so that the space between each pair of adjacent double portions and each adjacent pair of adjacent double portions is substantially equal to a length of a said band.
- The above spacing of the double portions on the feed roller is particularly advantageous by enabling, as in US Patent 5,715,838, the feed roller to accommodate substantially twice the number of double portions which would be permitted by the band assembly operation. Unlike US Patent 5,715,838, however, the above arrangement in pairs of adjacent double portions enables at least one of the double portions in each pair - in particular, the double portion downstream in the rotation direction of the feed roller - to receive the respective band even before reaching the rolling portion of the production line.
- Consequently, in a preferred embodiment of the above method, for each pair of adjacent groups, a first said band is supplied by a first of said two feed devices to a first group in said pair of groups, as the first group is fed along said input portion; and a second said band is supplied by a second of said two feed devices to a second group in said pair of groups, as the second group is fed along said rolling portion; said first group being located downstream from said second group with respect to a traveling direction of said groups along said production line.
- Preferably, in the method defined above, each said first group is fed along said first branch of the rolling portion of said production line, and each said second group is fed along said second branch of the rolling portion of said production line; each said second band being supplied to the respective said second group as the second group is fed along said second rolling branch.
- The present invention also relates to a machine for producing filter-tipped cigarettes.
- According to the present invention, there is provided a machine for producing filter-tipped cigarettes, the machine comprising a filter-tipped cigarette production line in turn comprising an input portion and a rolling portion; said input portion comprising a feed roller having a number of peripheral seats, supply means for feeding a succession of double portions into said seats, cutting means for cutting said double portions transversely into pairs of coaxial single portions, each said pair of single portions being housed inside a respective said seat, parting means for axially parting the single portions in each said pair of single portions; a supply device for inserting a double filter between the single portions in each said pair of single portions to form a respective group of three coaxial elements; said rolling portion comprising a first and a second rolling branch parallel to each other; two feed devices being provided on the same side of said production line to supply a band to each said group; and said second branch being interposed between said first branch and said feed devices; characterized in that said seats are arranged along the periphery of said feed roller in pairs of adjacent seats to form pairs of adjacent said groups along said input portion; said pairs of adjacent seats being equally spaced along the periphery of the feed roller so that the space between each pair of adjacent seats and each adjacent pair of adjacent seats is such as to substantially receive a said band.
