Definitions

  • the present invention relates to a curling device preferably for cigarette making machines.
  • the invention finds application to advantage in the art field of cigarette making machinery, and in particular of filter tip attachments, that is to say machine units by which filters and cigarettes are assembled. Reference is made explicitly to this art field in the following specification, albeit with no limitation in general scope implied.
  • cigarettes and filter tips are assembled by interposing a double length filter plug between two axially aligned cigarette sticks, then joining the filter to the sticks on each side by applying a previously gummed tipping paper, and ultimately cutting the double assembly in half to create two single filter-and-cigarette assemblies.
  • a filter tip attachment generally comprises a feed station from which a continuous strip of paper material is advanced at a predetermined velocity and under a predetermined degree of tension along a feed path, likewise predetermined; the feed path passes both through a gumming station at which an adhesive substance is applied to one surface of the strip destined to engage the filter-and-cigarette assembly, and through a cutting unit by which the continuous strip is divided into discrete tipping papers ready for application.
  • Each tipping paper separated by the cutting unit is positioned at an intermediate transfer station and there associated initially with a respective filter-and-cigarette assembly, before being affixed permanently to the selfsame assembly at a further station.
  • the step of affixing the tipping paper permanently to the filter-and-cigarette assembly is accomplished normally by wrapping the paper around the assembly.
  • the object of the present invention is to address and overcome the problems encountered in prior art solutions by setting forth a curling device for cigarette makers capable of deforming the fibers of a continuous strip in such a way as to facilitate the operation by which tipping papers are wrapped around filter-and-cigarette assemblies, while at the same time guaranteeing the integrity of the continuous strip and the quality of the finished cigarettes even at high operating tempos.
  • the stated object is realized according to the invention in a device for curling a continuous strip of paper material caused to advance along a predetermined feed path toward at least one cutting unit by which the selfsame strip is divided into discrete lengths.
  • a device presents at least one curling element operating on one surface of the advancing strip at a contact zone in such a manner as to deform the strip relative to its longitudinal dimension, and includes vibrator means associated with the curling element.
  • the curling device 1 denotes a curling device, in its entirety, embodied in accordance with the present invention.
  • the curling device 1 is associated with a given portion 2 of a cigarette maker, and in particular with a filter tip attachment comprising at least one feed station A from which a continuous strip 3 of paper or similar material is advanced steadily toward successive stations of the machine.
  • the continuous strip 3 is decoiled from a roll 4 , subject to a predetermined tension and at a given velocity, and advanced along a predetermined feed path P that passes in succession through a gumming station 5 , where one or more adhesive substances are applied to at least one adhesion surface 3 a of the continuous strip 3 , and a cutting unit 6 by which the gummed strip 3 is divided into discrete lengths, or tipping papers 7 , each serving to join at least one filter permanently to a respective cigarette stick.
  • the adhesive substances in question are applied at the gumming station 5 by means of at least one gumming device 8 comprising an applicator roller 9 that acts directly on the adhesion surface 3 a of the continuous strip 3 , and a reaction roller 10 acting on the surface of the strip opposite from the applicator roller 9 .
  • the strip 3 passes over a guide roller 11 positioned upstream of the curling device 1 , then through a pair of pinch rolls 12 downstream of the selfsame device 1 .
  • the cutting unit 6 generates the aforementioned tipping papers 7 utilizing a suction roller 14 and an auxiliary roller 15 of which the respective axes of rotation 14 a and 15 a are disposed substantially horizontal and parallel one with another.
  • the continuous strip 3 is taken up by the suction roller 14 , and directed through a cutting zone 16 at which the selfsame roller 14 interacts with the auxiliary roller 15 in such a way as to divide the strip 3 into single tipping papers 7 .
  • the suction roller 14 which presents a diameter greater than that of the auxiliary roller 15 and rotates at a peripheral velocity higher than the linear velocity of the advancing strip 3 , carries a plurality of angularly equispaced blades 17 with substantially straight cutting edges set skew to the axis of rotation 14 a.
  • the auxiliary roller 15 rotates at a peripheral velocity substantially matching the linear velocity of the advancing strip 3 , and carries a plurality of substantially radial blades 18 equispaced around its surface of revolution. These blades 18 present cutting edges set substantially parallel to the axis of rotation 15 a of the roller 15 .
  • the cutting unit 6 is followed along the feed path P by a conveying roller 19 of conventional embodiment, rotatable counterclockwise as viewed in the drawing, about an axis 19 a extending parallel to the axes 14 a and 15 a of the cutting rollers.
  • the conveying roller 19 affords a plurality of fluted recesses 19 b extending parallel to the straight line generators of the revolving surface, in which relative filter-and-cigarette assemblies 20 , each consisting in two cigarette sticks separated by a double length filter plug, are retained by suction in conventional manner.
  • the filter-and-cigarette assemblies 20 are caused to advance broadside by the conveying roller 19 through a transfer zone 21 where each successive tipping paper 7 generated by the cutting unit 6 is offered to the surface of a respective assembly 20 .
  • the curling device 1 is located upstream of the cutting unit 6 , considered relative to the feed direction D followed by the continuous strip 3 .
  • the device 1 will be positioned between the feed station A and the cutting unit 6 , and more exactly between the feed station A and the gumming station 5 .
  • the device 1 comprises a curling element 13 , embodied as a bar 22 appearing substantially triangular in section, of which one edge 13 a is offered to the adhesion surface 3 a of the continuous strip 3 at a contact zone denoted 23 .
  • the aforementioned guide rollers 11 and pinch rolls 12 are positioned along on the feed path P, relative to the curling element 13 , in such a way as to establish a leg presenting a Vee profile of which the vertex coincides with the edge 13 a of the bar 22 .
  • the strip 3 thus constrained to make a sharp change in direction at the contact zone 23 , the structure of the material becomes permanently deformed, assuming a predetermined curvature such that the gummed surface 7 a of each tipping paper 7 separated by the cutting unit 6 and then offered in contact to a filter-and-cigarette assembly 20 will be concavely profiled.
  • the edge 13 a of the curling element 13 is applied forcibly to the continuous strip 3 as it passes through the contact zone 23 , compressing the internal fibers beneath the surface directed toward the curling element 13 , while stretching the internal fibers beneath the surface directed away from the selfsame curling element.
  • the curling element 13 is connected by a rod 24 to vibrator means indicated schematically as a block denoted 25 , such as will cause the bar 22 to vibrate at a predetermined frequency.
  • the rod 24 might be replaced by any other means of connection capable of transferring the energy from the vibrator means 25 to the bar 22 , or alternatively, the bar 22 could be coupled direct to the vibrator means 25 .
  • the vibrator means 25 are of conventional type, for example electrical, mechanical or pneumatic in operation, and preferably will take the form of an ultrasound generator.
  • the vibratory motion transmitted to the bar 22 by the vibrator means 25 can be rectilinear, oriented along an essentially rectilinear direction parallel to the rod 24 , hence transverse to the strip 3 , or oriented along a direction transverse to the rod 24 and coinciding with the direction followed by the strip 3 as it passes through the contact zone 23 .
  • the vibratory motion can be generated by two directional components, one transverse to the other, in which case the trajectory described could be looped, elliptical or circular in outline.
