In an example embodiment, a doser assembly includes a hopper assembly configured to receive plant material, a bracket assembly connected to the hopper assembly, and a roller in a hopper opening defined by the hopper assembly extending through the hopper assembly. An interior surface of the hopper assembly may define the hopper opening. The bracket assembly may include a shaft extending across a portion of the hopper opening. The roller may be in the portion of the hopper opening of the hopper assembly and may extend between a first part and a second part of the interior surface of the hopper assembly. The roller may be connected to the shaft and may be configured to rotate with rotation of the shaft.

An ultrasonic sealing apparatus for paper packages achieves more stable ultrasonic sealing by cooling the horn during ultrasonic sealing which would otherwise be unstable due to heat imparted to a horn by continuous sealing. An end portion of a horn of a casing that includes the horn and a converter, or the horn, a booster and the converter is cooled by supplying air to a frame portion exposed toward an anvil side.

An anvil is provided in an ultrasonic sealing machine, in which vibration applying surfaces of a pair of horns and an abutment surface on an end face of the anvil cooperate with each other to bond a laminate. The abutment surface includes left and right welding surfaces which are disposed in the extending direction of the vibration applying surface and protrude toward the horns to face two vibration applying surfaces. The left and right welding surfaces each have an area per unit length in the extending direction, which continuously or step-wisely increases with an increase in distance from a center of the seal area, which is a region where the two vibration applying surfaces are adjacent to each other.

The present disclosure relates to an induction sealing system for heat sealing packaging material for producing sealed packages of pourable food products, said sealing system may include a sealing jaw and a counter-jaw. In some embodiments, the sealing jaw may include at least one inductor device having at least one active surface configured to contact said packaging material; at least one flux-concentrating insert; a supporting body including heat-conducting material, said supporting body housing, said at least one inductor device and said flux-concentrating insert; and an interactive surface configured to press against said packaging material. In some embodiments, the counter-jaw may include at least one pressure pad made of elastomeric material, said at least one pressure pad configured to provide a counter pressure to the sealing jaw, wherein said at least one pressure pad has an arched convex contact area with height in the direction towards the sealing jaw.

An assembly for producing sealed packaging units (14) from a sheet packaging material, comprises: an advancement device (21) for advancing the sheet packaging material along an advancement direction (F), a longitudinal sealing device for sealing opposite borders of the sheet packaging material along a longitudinal sealing band arranged parallelly to the advancement direction (F), thereby forming a continuous tube (15), a transverse sealing device (29) for sealing the continuous tube (15) transversely to the advancement direction (F), so as to define a sealed packaging unit (14). The transverse sealing device (29) comprises a sealing element (30) and an abutment element (31) that are intended to mutually cooperate during sealing while being located on opposite sides of the continuous tube (15). The sealing element (30) is so configured as to act on a side (27) of the continuous tube (15) on which the longitudinal sealing band is provided.

An ultrasonic sealing anvil is provided which is capable of applying an optimal pressure to an overlap part in the absence of misalignment between the overlap part and the anvil, and preventing application of an excessive pressure in the occurrence of misalignment. An ultrasonic sealing anvil is configured to seal a tubular material having an overlap part extending in one direction, in a sealing direction crossing the overlap part. The anvil is provided with a step that can be abutted with the overlap part R, and a pair of grooves arranged sandwiching the step in the sealing direction.

Certain implementations provide a form-fill-seal machine that can efficiently seal a packaging material. The transverse sealing unit may have first members to sandwich the packaging material and sealing the packaging material in a transverse direction, and second members for squeezing the packaging material while sandwiching the packaging material with a prescribed gap left therebetween. The control unit may cause the packaging material to be squeezed by the second members by causing the transverse sealing unit located at a reference position to descend faster than the packaging material being conveyed downward. The control unit may cause the transverse sealing unit to ascend while the packaging material is being sealed by the first members. The control unit may cause the transverse sealing unit to move such that the first members are separated from the packaging material.

The present invention relates to a blowing device (1) for blowing gas through a gas-permeable tubular-shaped packaging material (29). The blowing device comprises at least one gas nozzle (19; 75, 77), adapted to blow gas from an outside of the tubular-shaped packaging material through the tubular-shaped packaging material, and a guiding member (3), which comprises a web passage (5) having a surface (7) adapted to face the tubular-shaped packaging material, such that the web passage surrounds or substantially surrounds the tubular-shaped packaging material. The present invention further relates to a use of the blowing device, to a sealing arrangement (27, 71) for transversely sealing a gas-permeable tubular-shaped packaging material (29) and to an arrangement (37) for manufacturing of pouched products (39), which arrangement comprises such a sealing arrangement. The present invention also relates to a method for transversely sealing a gas-permeable tubular-shaped packaging material and to a method for manu facturing a pouched product, e.g. a portion-packed pouched oral snuff product.

A method for operating a tubular bag machine having a film web capable of unwinding from a supply reel, a shoulder for forming the web into a film tube, a take-off unit serving to move the tube, a longitudinal sealing device for welding the tube parallel to its transport direction by a longitudinal seam, a sealing device with jaws for producing transverse seams in the tube, a separating element for separating finished tubular bags from the tube, the machine being accelerated in a positive acceleration phase from an initial speed to a target speed when starting or being decelerated in a negative acceleration phase from the target speed to a final speed for stopping, wherein, in the positive acceleration phase and/or in the negative acceleration phase, at least one sealing parameter of the jaws for producing tubular bags changes as a function of the conveying speed of the web.
