摘要： The invention relates to a method for introducing elongated objects defining a longitudinal axis into a continuous flow of material, the method comprising the steps of: —providing a reservoir for holding the elongated objects to be introduced into the continuous flow of material; —introducing the elongated objects from the reservoir into a transfer chamber that is arranged such that the objects are aligned therein with their longitudinal axis parallel to each other; —moving the elongated objects along a direction parallel to their longitudinal axis in a single line path from the transfer chamber to a delivery channel by a rotatable wheel, the rotatable wheel arranged adjacent the transfer chamber and adapted to move the elongated objects located in the transfer chamber by contacting the elongated objects with a peripheral surface of the rotatable wheel; —inserting the elongated objects from the delivery channel to a location where the elongated objects are to be introduced into the continuous flow of material; and —regulating an insertion speed of insertion of the elongated object from the delivery channel to a location where the elongated objects are to be introduced into the continuous flow of material on the basis of a speed of the continuous flow of material at the location in which the elongated object is to be introduced.

摘要： A filter strip is provided for rolling sheets to construct custom cigars and/or cigarettes. The filter strip may be made of a deformable material which can be positioned on one end of the rolling sheet. The filter strip can be folded in a zig zag or spiral filter section with open section located longitudinally below to form a filter tip. The filter tip can assist the user in rolling by hand a substantially cylindrical or conical cigar or cigarette. The filter tip prevents tobacco filler material from being drawn through the cigar or cigarette and into a user's mouth, and permits the entire amount of tobacco filler to be consumed/smoked without risking burned hands and/or lips.

摘要： A system for portioning a beaded substrate in a rod. The system includes a suction conveyor belt. The suction conveyor belt includes a belt suction chamber, a first belt end, and a second belt end, the second belt end opposite and downstream of the first belt end. The system also includes a metering device configured to provide the beaded substrate to the suction conveyor belt, and more specifically to the first belt end. The metering device includes a reach and a hopper. The metering device may provide the beaded substrate to the first belt end prior to the suction conveyor belt biasing a filler material onto the first belt end. The system may further includes a cutting mechanism that cooperates with the metering device to position the beaded substrate a first distance away from a first cut end.

The forming nozzle includes a converging passage, at least one first internal cavity in fluid connection with a first working fluid source, and a plurality of first holes fluidly connecting the at least one first internal cavity with a working surface of the forming nozzle. The plurality of first holes are further positioned and directed such that in passing through the plurality of first holes, the first working fluid conveys the fibrous bundle material through the forming nozzle in a transport direction. A guide pin is disposed along a central axis of the converging passage, the guide pin including an elongated body which tapers in the transport direction. A bobbin disposed downstream of the forming nozzle.
