Method and member for guiding a strand of filter fibers and filter rod making machine

Abstract

The object of the invention is a member for guiding a strand of filter fibers in an area of placing objects into the strand of filter fibers in a tobacco industry machine, adapted to work together with an apparatus for feeding the objects to the strand of filter fibers, having a slot in which the feeding members of the object feeder move, an inlet opening for a strand of filter fibers, an outlet opening for a strand of filter fibers, a guiding channel connecting an inlet opening and an outlet opening. The member is characterized by comprising vent holes for stabilizing a strand of filter fibers being converted and increasing the accuracy of object placing.

1 .

         2 . The member as in  claim 1  characterized in that the axes of the vent holes ( 18 ) are situated radially. 
     
     
         3 . The member as in  claim 1  characterized in that the axes of the vent holes ( 18 ) are situated substantially perpendicular to the plane of the slot ( 13 ). 
     
     
         4 . The member as in  claim 1  characterized in that the vent holes ( 18 ) are situated substantially along at least one line. 
     
     
         5 . The member as in  claim 1  characterized in that the vent holes ( 18 ) are situated on both sides of the slot ( 13 ). 
     
     
         6 . A tobacco industry machine for making filter rods containing objects, comprising a treating unit for a strand of filter fibers, a continuous filter rod converting unit, an object feeding unit, a unit for cutting a continuous rod into individual rods, the tobacco industry machine being provided with a member according to  claim 1 . 
     
     
         7 . The machine as in  claim 6  characterized in that the object feeding unit comprises a delivery wheel. 
     
     
         8 . A method of guiding a strand of filter fibers in an area of placing objects into the strand of filter fibers in a tobacco industry machine, in a member for guiding the strand of filter fibers working together with an apparatus for feeding the objects to the strand of filter fibers, the member for guiding the strand of filter fibers having a slot in which move(s) a feeding member or members of the object feeder, wherein the strand of filter fibers is guided in a guiding channel from an inlet opening for the strands of filter fibers to an outlet opening for the strand of filter fibers, wherein the excess air contained among the fibers of the filter strand is discharged through vent holes so that a converted strand of filter fibers is stabilized and the accuracy of object placing is increased.
