Definitions

  • This invention relates to cigarettes and is particularly concerned with an improved method and apparatus for the production of filter tip and like composite cigarettes by uniting axially aligned 5 cigarettes or lengths of cigarette rod and filter tips or mouthpiece portions by means of uniting bands or wrappers.
  • the invention has for its primary object to provide an improved method of and means for applying the uniting bands or wrappers around the assembled lengths whereby the uniting operation may be effected without any rolling or other movement of the cigarettes, and whereby the wrapping pressure may be maintained to ensure l5 proper adhesion while the assemblages are being fed axially.
  • the present invention furthermore renders it possible, in a method involving the wrapping of uniting bands around assembled lengths fed ax- 20 ially to and from wrapping means, to effect the initial application of the uniting bands to the assemblages while the same are stationary and positioned in registration with the means for applying the uniting bands or wrappers.
  • the lengths to be united, assembled in line and after uniting bands or wrappers have been brought into contact therewith, are fed axially and intermittently, and the wrapping of the uniting bands or wrap- 30 pers around the lengths to be united is effected by the action of means moving lengthwise of the assemblage in a direction opposite to the feed movement thereof, the wrapping operation taking place during a period or periods when the :13 assemblage is stationary.
  • the wrapping operation is efiected by means reciprocated in the lengthwise direction of the assemblage, the wrapping movement in a direction opposite to the direction of feed taking place when the assemblage #:H is stationary and the return movement coinciding more or less with the forward movement of the assemblage.
  • FIGS. 1 and 1a taken together show a side elevation partly in section illustrating one embodiment of apparatus adapted for carrying out 55 the invention
  • Figure 2 is a section taken on line II--II of Figure 1;

  • the operation of the cam 6e raises the suction box I3 and thus presses the leading uniting band I I into contact with the assemblage.
  • the cam Be is arranged to maintain the suction box I3 in the raised position while the stop ID is released and the assemblage is discharged axially by the feed movement of the next following assemblage on the belt 9 and in order to maintain the uniting band II in contact with the assemblage during this movement, the suction box I3 may be provided with an extension plate I31 as shown in Figure 1.
