  • a separating unit may be located at the end of the duct and configured to receive the single-length longitudinal objects and to transfer the single-length longitudinal objects, one by one, to the positioning unit.
  • the positioning unit for placing the single-length longitudinal objects into the continuous filter rod may comprise a rotary positioning disc having a horizontal axis, wherein the positioning disc may comprise transporting seats for the single-length longitudinal objects.
  • the positioning unit for placing the single-length longitudinal objects into the continuous filter rod being formed may comprise a longitudinal pushing-off element for pushing the single-length longitudinal objects out of the transporting seats of the positioning disc.
  • the positioning unit for placing the single-length longitudinal objects into the continuous filter rod may comprise a rotary pushing element for pushing the single-length longitudinal objects out of the transporting seats of the positioning disc.
  • the machine may comprise a gluing unit for supplying glue onto the single-length longitudinal objects.
  • the gluing unit may have a nozzle for supplying glue is located at a circumference of the positioning disc.
  • the multiple-length longitudinal object may have a form of a tube.
  • the machine according to the present invention provides high quality of manufactured rods, the quality being indicated by both a repeatability of positioning of the tube along the rod, as well as a central positioning of the tube in a cross-section of the rod.
  • FIG. 1 An example of a filter rod 1 is presented in a cross-section in Fig. 1 . It comprises two longitudinal objects in a form of tubes 2.
  • the tubes 2 are located centrally along an X axis of the filter rod 1.
  • the tubes 2 are arranged along the X axis such that each filter rod 1 may be cut into two parts along a plane k that is perpendicular to the X axis, and each of that two parts may be cut along two planes: m and n, which are distanced from each other and from the plane k, and which are perpendicular to the X axis. Therefore, four mouthpieces 3 can be obtained from the single filter rod 1, wherein a full end 4 as well as a tube end 5 ( Fig.
  • Fig. 3 presents a multiple-length longitudinal object - a tube 6, which during the manufacturing process of the filter rods is cut into several tubes 2, which will be referenced herein as single-length longitudinal objects 2, wherein the multiple-length longitudinal object 6 is cut along several planes c perpendicular to a longitudinal axis Z of the tube 6.
  • a machine 10 for manufacturing filter rods 1 having single-length longitudinal objects 2 is shown in Fig. 4 .
  • the machine comprises a preparation unit 11 for preparing a strand of filtering fibers, a forming unit 12 for forming a continuous filter rod CR from a strand F of filtering fibers, a feeding unit 13 for feeding the multiple-length longitudinal objects 6 as a mass flow MF, a cutting unit 14 for cutting the multiple-length longitudinal objects 6 into single-length longitudinal objects 2, a transferring unit 15 for transferring the single-length longitudinal objects 2 as a flow of single-length longitudinal objects 2, a positioning unit 16 for placing the single-length longitudinal objects 2 into the continuous filter rod CR, a cutting head 17 for cutting the formed continuous filter rod CR (that comprises the filtering fibers and the single-length longitudinal objects 2), into single filter rods 1.
  • the strand F is subject to stretching, both in a transfer direction and in a direction transverse with respect to the transfer direction. Individual fibers of the strand F are separated, therefore it is possible to form a uniform rod having a circular cross-section in a preliminary forming unit 18 for forming the strand F of filtering fibers, in which the strand F of filtering fibers is gradually compressed, in order to make it possible to form a continuous rod CR having a circular cross-section at the output of the forming unit 12.
  • the machine comprises a wrapper feeding unit 19 for feeding a wrapper P.
  • the feeding unit 13 for feeding the multiple-length longitudinal objects 6 is located above the forming unit 12 for forming the continuous filter rod CR from the strand F of filtering fibers.
  • the feeding unit 13 comprises a channel 20 configured to feed the multiple-length longitudinal objects 6 in the form of the mass flow MF i.e. a multilayer stream of the multiple-length longitudinal objects 6.
  • the feeding unit 13 comprises a hopper 21 located directly above the cutting unit 14.
  • the cutting unit 14 comprises a multi-flute drum conveyor 22 and a disc knife unit 23.
  • the multiple-length longitudinal objects 6 are placed into the flutes of the drum conveyor 22 and the single-length longitudinal objects 2 obtained after cutting are received from the flutes of this conveyor in order to form the flow SF of single-length longitudinal objects 2.
  • the single-length longitudinal objects 2 are transferred as the flow SF of single-length longitudinal objects 2 along a substantially horizontal duct 25 ( Fig. 5 ).
  • the single-length longitudinal objects 2 are transferred in groups G by means of pushers 24, wherein only one group G is presented in the drawing to improve clarity.
  • the single-length longitudinal objects 2 are transferred further by means of a transferring drum 26 having a spiral element 27 located on a side surface 28 of the transferring drum 26.
  • the spiral element 27 pushes the single-length longitudinal objects 2 during rotation of the transferring drum 26.
  • the single-length longitudinal objects 2 are transferred from the transferring unit 15 to the positioning unit 16 directly or by means of a separating unit 29.
  • the aim of the positioning unit 16 is to place the single-length longitudinal objects 2 inside continuous, cylindrically shaped strand F of the acetate fibers being formed, the single-length longitudinal objects 2 being placed by means of a positioning disc 30 with transporting seats 31.
  • the transporting path of the flow SF may be located tangentially to the positioning disc 30. Placing of the single-length longitudinal objects 2 is performed when the fibers are initially formed, loosely enough, so that when the single-length longitudinal object 2 is being inserted, the fibers of the strand F are moved apart and will surround this object during further forming of the fiber strand F, such that a uniform density of the filtering material can be obtained around the said object.
  • the density of the strand F of the filtering fibers (across the cross-section of the strand) at this stage is low and uniform enough, so as to achieve accurate central positioning of the single-length longitudinal object 2 in the filtering fibers strand F by means of the positioning disc 30 in the continuous rod CR.
  • the transporting seats 31 may be formed by means of pushers 32 on a circumference 33.
  • the rotary motion of the positioning disc 30 defining the position of the single-length longitudinal objects 2 is synchronized with the transferring of the wrapper P and the strand F of the filtering fibers, therefore the longitudinal arrangement of the single-length longitudinal objects 2 in the continuous rod CR being formed is repeatable and set with high accuracy.
  • the positioning disc 30 has a horizontal axis Y of rotation.
  • the positioning unit 16 for placing the single-length longitudinal objects 2 in the filter rod comprises a longitudinal pushing element 34, presented in a cross-section in Fig. 7 , for pushing the single-length longitudinal objects 2 out of the transporting slots 31 of the positioning disc 30 during rotation of this disc.
  • the stationary pushing elements 34, 34' may be substituted by rotary mounted pushing elements 37, 37', for example such as discs presented in Fig. 8 and presented in a cross-section in Fig. 9 .
  • the purpose of the stationary pushing elements 34, 34' as well as the rotary mounted pushing elements 37, 37' is to provide the central positioning of the single-length longitudinal objects 2 in the cross-section of the continuous rod CR, because the central positioning is set for the whole length of the inserted object.
  • the transporting seat 31' may have a form of a cylindrical groove of a diameter corresponding to the diameter of the single-length longitudinal object 2.
  • the single-length longitudinal objects 2 may be held by means of an arc guide 38.
  • the single-length longitudinal objects 2 may be held in the transporting seats 31' by means of negative pressure supplied through ducts 39.
  • a gluing unit 35 configured to supply glue onto the single-length longitudinal objects 2.
  • the gluing unit may have a nozzle 36 that supplies the glue in a cyclic pulse manner. Owing to use of the glue, a single-length longitudinal object 2 is being fixed immovably with respect to the fibers of the continuous filter rod CR that is being formed.
  • Fig. 10 presents a fragment of the machine comprising the positioning unit 16' with transporting seats 31' arranged peripherally by protrusions 40 at the circumference 33' of the positioning disc 30'.
  • Each transporting seat 31' has two protrusions 40, which limit the single-length longitudinal object 2 which is placed in the transporting seat 31' at both sides.
  • Such solution facilitates obtaining a uniform longitudinal arrangement of the single-length longitudinal objects 2 in the continuous rod CR, because the positioning of the single-length longitudinal object 2 is defined at both sides.
  • the single-length longitudinal object 2 is fed into the transporting seat 31' from the top by means of the separating unit 29.
  • the single-length longitudinal object 2 is transferred in the transporting seat 31', wherein at the outside it is held by means of a guide 38' having an inner guiding surface 41 corresponding to the diameter of the single-length longitudinal object 2 ( Fig. 11 ).
  • the guides may have any shape.
  • Side guides 42, 42' may be additionally implemented, which are referenced by dashed lines.
  • Fig. 11 presents also two gluing units 35', which supply glue onto the outer surface of the single-length longitudinal object 2. Alternatively, it is possible to locate the gluing unit only at one side of the transporting path of these objects.
