  • Patent number: 11944119
    Abstract: Apparatuses are provided for manufacturing a rod member for a cigarette filter element. Each rod member defines a longitudinal axis and includes a generally longitudinally-extending filter material and a plurality of objects disposed therein along the longitudinal axis. Such an apparatus comprises a rod-forming unit configured to form a continuous supply of a filter material into a continuous cylindrical rod member. An object insertion unit is configured to introduce a plurality of objects into engagement with the rod member. A rod-dividing unit is configured to divide the rod member into a plurality of rod portions such that each rod portion includes a plurality of the objects. Associated methods are also provided.

  • Publication number: 20240042747
    Abstract: The invention features a reinforcement element including a continuous paper strip having a first side and a second side, a first adhesive composition disposed on at least one of the first side and second side. The invention further features a paper reinforced tape including a continuous paper strip, a continuous paper backing layer and a first adhesive composition disposed between the continuous paper strip and the continuous paper backing layer thereby adhering the continuous paper strip to the continuous paper backing layer. The paper reinforced tapes and reinforcement elements of this invention have improved repulpability, recyclability, compostability and biodegradability. Further, these reinforcement elements and paper reinforced tapes, despite being predominately paper, unexpectedly provide excellent container reinforcement properties and further can be used as opening tapes, closing tapes and carrying handles.

  • Patent number: 9764512
    Abstract: Systems and methods are disclosed for starting a strip material in a substrate processing machine wherein the machine is not stopped and/or operators do not have to reach into the running machine to start the strip material. Exemplary systems include a strip material guide apparatus including at least one guide arm and at least one gas stream generator configured to direct strip material from the guide arm into a substrate processing machine to join the strip material with one or more running substrates. The gas stream generator is operable to cause a leading end of a strip material dispensed from the guide arm to be conveyed via a gas stream toward the running substrates, such that the leading end of the strip material becomes engaged by the substrate processing machine and the strip material joins with the running substrate.
