A welding promoting element for an opening device is insertable into a lid (25) of said opening device to connect said lid (25) to a closing element (10) closing a pouring opening (14) of said opening device; the welding promoting element comprises a sheet element (31) provided with a layer (32) of electrically conductive material, with a first layer (33) of heat-sealable plastic material and with a second layer (34) of heat-sealable plastic material arranged on opposite sides of said layer (32), said layer (32) having a thickness comprised in the range 5-15 m and each of said first layer (33) and second layer (34) having a thickness comprised in the range 10-50 m.

A thermo-sealing machine for filling containers with liquids and sealing them, comprising a bearing structure on which a bell member is mounted, at a higher position than that of support means for supporting at least a container to be filled and sealed, said bell member comprising a metering device, die-cutting means and sealing means, for die-cutting and sealing a film slidable between said bell member and the container to be filled, said machine being provided with an anti-polluting and operator safety system.

A binding machine comprising: a feeding device for feeding a binding element (3) in the form of a wire or strap in a loop around one or more objects to be bound and subsequently retracting the binding element to draw it tightly around said objects; and a laser welding device for forming a welded joint between a section at the leading end of the binding element and an adjoining section at the trailing end of the part (3a) of the binding element fed in a loop around said objects to thereby secure this part of the binding element in a loop around the objects. The laser welding device is configured to apply an identification marking on an outer surface of the binding element by means of a laser beam (14) emitted from a laser welding head of the laser welding device.

A station for sealing thermoformed containers for a packaging line and a method for sealing the containers includes a sealing carousel which rotates continuously about a central axis and includes sealing heads which are radially spaced apart from said central axis. Each sealing head is adapted to receive at least one container to be sealed at a first, input, peripheral region, which is outside the sealing carousel; receive at least one closing seal at a second, input, peripheral region, which is outside the sealing carousel; and hold the closing seal and the container during the rotation of the sealing carousel and couple them together.

The station further releases the container complete with the closing seal at a third, output, peripheral region, which is outside the sealing carousel and angularly spaced from the first and from the second region.

A method for producing a portion unit of a detergent by inserting a base element made from a first film portion into a deep-drawing mold that forms a holding volume from the first film portion, the holding volume having a plurality of chambers spaced apart from one another; pouring at least one detergent composition into the chambers; placing a cover element made from a second film portion onto the filled chambers; connecting the cover element to the base element, which forms a film wrapping, sealing seams being formed between adjacent wall portions of the chambers; removing the portion unit from the deep-drawing mold, wherein the outside of the film wrapping is then wetted at least in the region of the adjacent wall portions and, by pressure being exerted, the sealing seams are compressed and the adjacent wall portions are brought into contact with one another and interconnected.

The containers are thermoformed in groups, filled, and closed. Then, the containers are separated, and placed adjacent to one another in such a manner that segments of their respective rims face each other and define between them a line of separation. On said line, at least one spot weld is formed that forms a breakable connection between the facing rim segments.

An insert, a floating nut and methods for use thereof in a panel of an aircraft are presented. Specifically, an insert includes a housing defining a cavity. An aperture is further defined in a first end of the housing and a semi-spherical portion is defined at a second end of the housing. A pair of vent openings are also defined on opposing sides of the first end of the housing.

A welding promoting element for an opening device is insertable into a lid (25) of said opening device to connect said lid (25) to a closing element (10) closing a pouring opening (14) of said opening device; the welding promoting element comprises a sheet element (31) provided with a layer (32) of electrically conductive material, with a first layer (33) of heat-sealable plastic material and with a second layer (34) of heat-sealable plastic material arranged on opposite sides of said layer (32), said layer (32) having a thickness comprised in the range 5-15 m and each of said first layer (33) and second layer (34) having a thickness comprised in the range 10-50 m.

Embodiments of the present disclosure are directed to leak-free exercise devices that are soft and conformable due to being filled with granular material. The devices are formed from one or more flexible panels joined together to form a cavity and a filler material, such as sand, contained within the cavity. The devices comprise welded seams that prevent liquid or moisture from entering the cavity and/or granular material from exiting the cavity. In some embodiments, the one or more flexible panels may further be made of waterproof materials.

A plastic tank is comprised of two parts, a base and a top, that are permanently joined to each other by welding at a circumferential joint formed by two mating flanges of the parts. The faying surfaces of the flanges of the top and base have portions in the shape of a hollow truncated cone. Fusion weld elements are captured on the faying surfaces of the flanges of the assembled parts, and the elements melted by internal heating of metal portions of the elements.
