A method of forming an oral product includes extruding a mixture, conveying the extruded mixture through one or more pairs of forming rollers, and cutting the extruded mixture into one or more oral products. The mixture can include polymer and at least one flavorant, sweetener, active ingredient, or combination thereof. The extruded mixture forms an extrudate having a predetermined cross-sectional shape. The one or more pairs of forming rollers abut to define a passage there between as each forming roller rotates. The passage has a cross-sectional shape corresponding to the predetermined cross-sectional shape. The method can be performed using a machine including an extruder, one or more pairs of forming rollers, and a cutting device.

An extruder which can be applied to various types of resin and elastomer without having to replace a die is provided. An extruder of the present inventions has: a barrel to which raw material, that is raw elastomer or raw material resin, is supplied; a screw that is driven to rotate in the barrel in order to process the raw material together with the barrel; and die 5 that is provided at a discharge point of the barrel and that discharges the raw material that has been processed. Die 5 includes first flat plate 11 having at least one first hole 13 and second flat plate 12 having at least one second hole 14, wherein first flat plate 11 and second flat plate 12 are arranged adjacent to each other along longitudinal axis X1 of the barrel, and at least either first flat plate 11 or second flat plate 12 is movable relative to the other flat plate such that an overlapping part of first hole 13 and second hole 14 can be varied.

The invention relates to an improved method and to an improved device for degassing polymer melts and for neutralizing the thus produced pollutants, characterised by the following characteristics: said pollutants are guided to a plasma source after removal from the degassing area and prior to adding to a filter step or a separator, said plasma source being built and/or formed such that in said plasma source, the pollutants are transformed, entirely or partially, in a plasma aggregate state.

A machine for forming a plurality of oral products includes an extruder, pairs of forming rollers, and a cutting device. The extruder is configured to form an extrudate. The pairs of forming rollers include a first pair of forming rollers and a second pair of forming rollers. The first pair of forming rollers cooperate to define a first passage therebetween. The first passage is configured to receive the extrudate from the extruder. The second pair of forming rollers cooperate to define a second passage therebetween. The second passage is configured to receive the extrudate from the first pair of forming rollers. The cutting device is configured to receive the extrudate from the first pair of forming rollers and cut the extrudate.
