SEALING DEVICE
The present invention relates to a sealing device (1, 101, 201) for sealing a packaging material (7, 107) enclosing a filling material (29) to provide portion-packed oral pouched snuff products (43). The sealing device comprises an anvil (3, 103, 203) with a first operation surface (11, 111, 211) and a sonotrode (5, 105, 205) with a second operation surface (13, 113), the anvil and the sonotrode being arranged to allow passage of the packaging material therebetween, the second operation surface being located opposite the first operation surface during operation of the sealing device. The first and second operation surfaces are arranged to weld a first portion (7a, 107a) of the packaging material to a second portion (7b, 107b) of the packaging material. At least one of the first or second operation surfaces comprises a first welding surface (11a, 111a) defining a first extension plane and a second welding surface (11b, 111b) defining a second extension plane, which has a different orientation than the first extension plane. The first and second welding surfaces are partly delimited by a cutting edge (15, 115, 215) having an extension direction along the first and second welding surfaces, such that the cutting edge separates the first welding surface from the second welding surface. The present invention further relates to an arrangement (19) for manufacturing of portion-packed oral pouched snuff products, which arrangement comprises such a sealing device. The present invention also relates to a method for portion-packing of an oral pouched snuff product.
AN ORAL POUCHED SNUFF PRODUCT
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.
Bonding and slitting device
A bonding and slitting device is adapted to form fin seams in absorbent articles having a front waist region, a back waist region, and a crotch region extending between the front waist region and the back waist region. The device includes a first bonding member and a second bonding member having a contact element configured to cooperate with the first bonding member to bond the front region of the chassis to the back region to define the fin seams. A slitter is configured to simultaneously act on material outboard of the bonds from both the front and back regions of the chassis.
Catheters with lubricious linings and methods for making and using them
Apparatus and methods are provided for creating tubular devices, e.g., as components for catheters, sheaths, and or other devices sized for introduction into a patient. In one embodiment, a method is provided for making a tubular device using a sheet of material including a coated first surface. The sheet is rolled around a mandrel until longitudinal edges of the sheet are disposed near or adjacent one another, e.g., without attaching the longitudinal edges together. A tubular braid is positioned over the sheet-wrapped mandrel, one or more tubular segments are positioned over the tubular braid, and heat shrink tubing is positioned over the tubular segments. The resulting assembly is heated to cause the tubular segments to at least partially reflow and/or otherwise laminate the tubular segments to the tubular braid and sheet. The heat shrink tubing and mandrel are then removed to create the tubular device.
METHODS OF BONDING THAT EMPLOY PREHEATING
Methods and devices for bonding a plurality of substrates in a nip provided between an anvil and a bonding device may involve preheating a portion of a first substrate for a preheating duration to impart a preheated temperature, and then conveying the plurality of substrates to the nip to form a bond. The portion of the first substrate may reach the nip at a final temperature that is within 0 C. to 40 C. of the preheated temperature. A time-in-nip to create the bond may be less than 20 milliseconds. The preheating duration may be at least 200% longer than the time-in-nip. Laminate materials formed via such methods and devices may include unbonded areas in the nonwoven material that may have at least 5 fibers per square inch that are fused at fiber-to-fiber intersections caused by preheating the nonwoven material.
Dual roller applicator for seam tape
A one-handed tool for use in application of seam tape or seaming tape. The device has a frame with an upper support with an ergonomic grip, with a finger guard or shield extending across the front of the grip to protect the user's fingers. A primary roller support and a secondary roller support extend downward from upper support. Each roller support comprises a pair of parallel arms extending downward at angles behind and in front of the upper support when in use, supporting a primary roller and a secondary roller, respectively. The primary roller is used to apply pressure to the seaming tape, while the secondary roller is used for stability and to apply additional pressure to the edges of the seaming tape.
Insect net lamella and method of producing the same
Described is an insect net strip produced from a wide insect net which has been cut in a warp direction (xnet) by means of a one-step ultrasonic cutting and welding process. The insect net strip includes warp yarns and weft yarns extending substantially perpendicular to each other and at least 90% of the warp and weft yarns are monofilament yarns made of a thermoplastic material. After cutting and welding process the insect net strip has a first and a second edge extending parallel to said warp yarns each including a deformation zone being constituted by consolidated thermoplastic material deriving at least from said weft yarns. The deformation zone has a width (wdz) in the transverse direction (ystrip) of between 0.5-35 times the weft yarn diameter (we). At least 90% of gaps between adjacent weft yarns in the deformation zone are closed by consolidated thermoplastic material at least from the weft yarns which has been melted together to form a continuous or substantially continuous reinforced band-shaped edge portion of said insect net strip. The insect net strip is suitable for use in accordion-style constructions in greenhouse ventilation openings. A method for producing the insect strips is also described.
