The present invention relates to a method for portion-packing of an oral pouched snuff product (1, 1). The method comprises a) supplying and advancing a tubular web (19, 19, 19) of packaging material enveloping a continuous feed (23, 23, 23a, 23b) of filling material in a direction of travel (L), b) forming transverse seals (39) in the tubular web across the continuous feed of filling material by means of ultrasonic welding, the transverse seals extending in a transverse direction (T) being perpendicular to the direction of travel. The present invention further relates to an arrangement (17, 17, 17) for portion-packing of an oral pouched snuff product.

Aspects of the disclosure relate to manufacturing balloon envelopes for use in high-altitude mesh networks for packet-data communications. As an example, a gore portion may be placed on a table such that the gore portion overlies a groove within the table. A tendon may be placed on the gore portion and within the groove. A portion of tubing may be placed over the tendon. The tubing may have one or more surface openings. Restraining tape is applied over the one or more surface openings in the tubing. A constant force roller is applied to secure the tendon to the gore portion and to secure the tendon to the tubing. As an alternative or in addition to the surface openings, double-sided restraining tape may be placed between the tendon and the tubing. The tubing and restraining tape may prevent undesired lateral and longitudinal movement of the tendon during deployment.

The invention relates to a stamp-sealing unit comprising a punch designed as a sonotrode (8), and a die (5), said die (5) having an opening (15) and the punch being able to be moved in and out of the opening (15) in the stamping direction. The invention also relates to an ultrasonic processing device for stamping stamped parts out of a stamping material (2) and for sealing the stamped parts to unprocessed products (21).

A type of PVC related disposable gloves and the manufacturing process thereof. The process includes: The PVC resin or its mixture is mixed with a plasticizer to form a glove formula mixture. The films of glove material mixture are formed with the said glove formula mixture. Two layers of the said films of glove material mixture are placed in parallel to form the glove material films An insulation layer is placed on one side of the glove material films, and a beam of electromagnetic waves is applied and distributed along a path of preset contour onto the surface of the glove material films so that the electromagnetic beam penetrates the glove material films and, as the result, the two layers of the glove material films are effectively sealed and joined along the path of preset contour; Or thermal heat is applied and distributed along a path of preset contour onto the surface of the glove material films so that the heating temperature is equal to or higher than the critical point of heat sealing temperature of the glove material films and, as the result, the two layers of the glove material films are effectively sealed and joined along the path of preset contour. Pressure is applied on the glove material films along the path of preset contour so that the two layers of the glove material films are fused integrally along the path of preset contour. A cutting edge is applied along the outer path of preset contour, and the inner part of the path of preset contour including the fused part is separated from the glove material films, while an opening at the wrist is cut, so that a piece of the PVC related disposable glove is formed. This manufacturing process of the PVC related disposable gloves greatly reduces the environmental pollutions and has a very high value for in protecting the environment.

A method for producing a breathable web, comprising: feeding a web on the surface of an anvil roller rotatable about its axis and having a plurality of welding protrusions cooperating with a welding element, welding said web at a plurality of welding spots on head surfaces of said welding protrusions and forming respective annular welding seams at said welding spots, about respective welding projections, and respective thin membranes located within said annular welding seams and adjacent to the head surfaces of said welding protrusions, and removing said thin membranes after said welding by means of a peeling roller having an outer surface tangent to said head surfaces of said welding protrusions.

The machine (1) comprises: retaining means (3, 4) of a first profiled element (5) and of a second profiled element (6) made of plastic material, which extend along respective longitudinal directions and are each provided with at least one area to be welded (7) substantially inclined by an angle comprised between 10? and 80? with respect to the respective longitudinal direction and at least one main face (5a, 6a) square-shaped, wherein the main face (5a) of the first profiled element (5) is projected with respect to the respective area to be welded (7) and the main face (6a) of the second profiled element (6) is recessed with respect to the relevant area to be welded (7); removal means (16) comprising a pair of milling tools (17) movable in rotation around a relevant axis of rotation (R); suction means (20) adapted to remove the residues of plastic material generated during the removal of the plastic material;
wherein the suction means (20) comprise at least one suction duct (21) arranged around a respective milling tool (17), which comprises a substantially flat abutment portion (24) adapted to internally abut against the main face (5a) of the first profiled element (5) during the removal of the plastic material.

The invention relates to a stamp-sealing unit comprising a punch designed as a sonotrode (8), and a die (5), said die (5) having an opening (15) and the punch being able to be moved in and out of the opening (15) in the stamping direction. The invention also relates to an ultrasonic processing device for stamping stamped parts out of a stamping material (2) and for sealing the stamped parts to unprocessed products (21).

Aspects of the disclosure relate to systems and techniques for inspecting seals for high altitude balloons. In one example, a system may include a reflective surface, a translucent material on the reflective surface, and a movable light source configured to move along the reflective surface and provide light to the reflective surface. The light is provided such that it is reflected from the reflective surface and through the translucent material in order to backlight a balloon envelope seal for inspection. A method for inspecting a balloon envelope seal may include placing balloon envelope material on a table, forming a seal between portions of the material, moving a light over the seal, shining light onto a reflective portion of the table below the seal to backlight the seal, and inspecting the seal using the backlighting of the seal.

The invention provides a tool 10 of the invention for welding a PET gland 12 onto a PET bottle 14 for the fitment of a dispensing tap. The tool 10 is generically indicated as ultrasonic horn or sonotrode in the figure. The ultrasonic horn has a tapered serrated portion 16 which has a lead-in taper section 18 to initiate the melt of the plastics to be welded, and a knife section 20 (when required), being the cutting zone thereof, which in use cuts open a sealed spigot 22 so that the horn can enter into the spigot 24 for the welding operation.

Aspects of the disclosure relate to techniques for manufacturing a balloon envelope. In one example, a first sheet of material for a first gore of the balloon envelope is provided. Lap seal material is arranged at least partially on the first sheet of material. A first heat seal is created between the lap seal material and the first sheet of material. A second sheet of material for a second gore of the balloon envelope is arranged over the first heat seal. A second heat seal is created between the lap seal material and the second sheet of material such that the lap seal material is configured to provide additional structural support to the balloon envelope.
