A deep-drawing packaging machine that includes a sealing station and a method for changing the sealing frame together with the sealing plate at the sealing station. The sealing station includes a sealing plate and a sealing frame. The sealing plate may be releasably coupled to an upper sealing tool part, and the sealing frame may be slidably removable at a lower sealing tool part. The sealing frame may be slidable on rails. The sealing frame may include one or more centering aids for aligning the sealing plate with respect to said sealing frame during removal thereof. The centering aids may be displaceable underneath a film web by the upper sealing tool part during the clamping of the film web between the sealing frame and the upper sealing tool part.

The present invention relates to a wind turbine blade and a method for its manufacture. A lower shell part and an upper shell part are provided, each shell part having a leading edge and a trailing edge. A first shear web and a second shear web for connecting an inner surface of the lower shell part with an inner surface of the upper shell part are provided. The first shear web and the second shear web are connected by a first distance member in a chordwise direction. The first distance member is arranged for accommodating a variable chordwise distance between said first shear web and said second shear web. The first shear web and the second shear web are placed in the lower shell part and the upper shell part is mounted.

A laser welded structure is formed by laser welding together a resin molded body formed from a thermoplastic polymer alloy containing a crystalline resin and an amorphous resin and a metal body made of a metal. A glass transition temperature of the amorphous resin is lower than a melting start temperature of the crystalline resin.

The present invention provides a vehicle lamp comprising a lens molded article (1) and a housing molded article (2) laser-welded to each other, the lens molded article (1) comprising a methacrylic resin composition which comprises 70 to 99.9% by mass of a methacrylic acid ester monomer unit and 0.1 to 30% by mass of a unit of an additional vinyl monomer copolymerizable with the methacrylic acid ester monomer and satisfies conditions (a) to (c), and the housing molded article (2) comprising a resin which satisfies a condition (d): (a) MW is 90000 to 250000; (b) a mass (MFR-1) of the methacrylic resin composition emitted according to ISO1133 standard at 230° C. and 3.8 kg for 10 minutes is 0.2 to 12 g/10 min; (c) when a mass of the methacrylic resin composition emitted according to the ISO1133 standard at 230° C. and 10 kg for 10 minutes is defined as MFR-2, MFR ratio=(MFR-2)/(MFR-1) is 4.5 or more; and (d) a mass (MFR-3) of the resin emitted according to the ISO1133 standard at 220° C. and 10 kg for 10 minutes is 2 to 45 g/10 min or smaller.

A bladder device is for moving a component of a web packaging machine that forms and encloses a food product in a food product package made of webs of packaging material. The bladder device has a bladder and a nipple stub coupled to the bladder and having a first end configured to receive a gas and a second end configured to dispense the gas into the bladder to thereby inflate the bladder and move the component of the web packaging machine. A collar coupled to the nipple stub such that the bladder is sandwiched between the collar and the second end of the nipple stub. The second end of the nipple stub has a depression and the collar has a boss that is oriented towards the depression such that tightening the collar on the nipple stub forces the bladder into the depression and thereby forms a fluid tight seal.

An air conditioning piping system of the disclosure includes a refrigerant pipe made of a plastic material and configured to provide a fluid flow between components constituting an air conditioning system; at least one connection flange made of the plastic material and configured to provide a connection between the refrigerant pipe and components constituting the air conditioner system; and at least one charging port made of the plastic material and having a charging valve configured to inject a refrigerant into the refrigerant pipe.

A package includes a closure and a container. The closure is adapted to mate with a brim of the container to close a top opening arranged to open into an interior product-storage region formed in the container.

The invention relates to a device comprising a first fixing element, a further fixing element and a folded planar composite; wherein the first fixing element comprises a first fixing surface and the further fixing element comprises a further fixing surface; wherein the folded planar composite is at least partially fixed between the first fixing surface and the further fixing surface; wherein the folded planar composite comprises a first composite region; wherein the first composite region comprises a first layer sequence comprising a first composite layer comprising a first carrier layer, a second composite layer comprising a second carrier layer, a third composite layer comprising a third carrier layer and a fourth composite layer comprising a fourth carrier layer; wherein in the first composite region the second composite layer is joined to the third composite layer and the third composite layer is joined to the fourth composite layer; wherein in the first composite region the third carrier layer is characterised by a smaller layer thickness than in each case one selected from the group consisting of the first carrier layer, the second carrier layer and the fourth carrier layer or a combination of at least two of these; wherein the first fixing surface or the further fixing surface or both comprises a recess comprising a first recess region; wherein the first composite region is located at least partially between the first recess region and the first fixing surface or the further fixing surface.
