A product delivery system is provided to deliver product from a positive displacement pump to a product delivery tube. A control system is structurally configured to direct the positive displacement pump to operate in two different modes, a first, continuous operating mode and a second, dosing operating mode. A method of filling is likewise disclosed.

The present disclosure relates to an oral pouched snuff product comprising a filling material and a saliva-permeable pouch enclosing the filling material, the oral pouched snuff product having a longitudinal direction and a transverse direction perpendicular to said longitudinal direction, the saliva-permeable pouch comprising a first elongated seal and a second elongated seal, each of said first and second elongated seals having a seal length extending along the transverse direction of the product and a seal width extending along the longitudinal direction of the product, wherein the seal width of said at least one elongated seal being equal to or less than 2 mm, such as within the range of from 0.1 mm to 2 mm or from 0.1 mm to 1 mm or from 0.1 mm to 0.5 mm. There is also provided a container having a base and a detachable lid together providing an interior container space in which a plurality of these oral pouched snuff products is contained.

A method of constructing an inflatable fluidic actuator. The method includes coupling a first interface to a tube configuration of membrane material at a first tube end by coupling the first interface to the tube configuration at the first tube end by generating at least one of: a first bond between the membrane material and one or more first sidewalls of the first interface and a first external face bond between membrane material at the first tube end onto a first external face of the first interface.

A flexible sealing tube is described that is adapted to be installed in and extend along a bore in the ground for use in a system for exchanging of energy with the ground. The flexible sealing tube has a first tube end to be installed at an inner part of said bore, and the flexible sealing tube is closed in the first tube end. The flexible sealing tube also has a first channel and a second channel extending in a longitudinal direction (L) of the flexible sealing tube, the first and second channels being in fluid connection with each other. The first and second channels are formed by the flexible sealing tube.

There is described a method for forming a tube (3) of a web (4, 4) of packaging material comprising the steps of advancing the web (4) of packaging material along a web advancement path (P), overlapping a first lateral edge (19) of the web (4, 4′) of packaging material with a second lateral edge (20) of the web (4, 4) of packaging material for obtaining a longitudinal seam portion of the tube (3) and fusing at least an internal outer surface (34) of the first lateral edge (19) and an external outer surface (37) of the second lateral edge (20) with one another for longitudinally sealing the seam portion of the tube (3). The step of fusing comprises at least the substeps of directly heating the external outer surface (37) of the second lateral edge (20) and heating by contact the internal outer surface (34) by establishing contact between the internal outer surface (34) and the directly heated external outer surface (37).

A laminate tube with an invisible longitudinal overlapped side seam formed from overlap welding an edge of one margin of a laminate sheet comprising an outer plastic layer (A), a barrier layer (B), and an inner plastic layer (C) of the same material type as the outer plastic layer (A) to the other edge of the opposite margin of the laminate sheet, such that an inner surface of the laminate tube has a hump in a overlapped region, while an outer surface of the laminate tube is smooth without a hump in the overlapped region; and a process for manufacturing the laminate tube by a laminate tube manufacturing machine. The laminate permits fracture-proof welding of longitudinal margins of said laminate to give a continuous tube which is suitable for manufacturing of high-quality plastic tubes, high-quality plastic bags and the like.

A bag-making and packaging machine forms a sheet-like film into a tubular shape and transversely seals the film to manufacture bags containing articles. The bag-making and packaging machine includes a transverse sealing mechanism and a control unit. The transverse sealing mechanism pinches and transversely seals the tubular film that has been formed into a tubular shape to form a transverse seal portion. The control unit determines whether or not there is jamming in the transverse seal portion and, in a case where it has determined that there is jamming, switches between a first bag-making process to continue bag-making operation and a second bag-making process to stop bag-making operation based on a jamming state.

The invention relates to improvements of a heating means particularly in a vertical flow-wrapper.

A method and/or a machine is for tabbing a free end on a roll of sheet material. Converting a master roll of sheet material to the roll of sheet material and winding a first roll of sheet material onto a spindle at a winding position. Tabbing the free end of the roll of sheet material at a tabbing position. Where a tabber carrying a joiner are both in an initial position away from the first roll of sheet material, moving the tabber to a second position adjacent the roll of sheet material, moving the joiner into an engagement position where the joiner is engaged with the free end of the roll of sheet material. The joiner creates a tab with a combination of mechanical entanglement and heat welding. Returning the tabber and joiner to the initial positions. Doffing the tabbed roll of sheet material. The roll produced by the foregoing.
