A rotary impulse sealer for forming a series of discrete bonds in a bondable material. The rotary impulse sealer has a roller rotatable about an axis. The roller has a roller body and a plurality of seal bars extending radially outwardly from the roller and spaced apart around the roller body. At least one of the seal bars has a body and a selectively heatable heating element extending along at least a part of a length of the seal bar body. The roller is rotatable through a pre-heating pressure application region in which the at least one seal bar is adapted to apply pressure to a bond area of the bondable material, followed by a heating region in which the at least one seal bar is adapted to heat the bond area, the regions being stationary with respect to the rotation of the roller. A method of forming packages containing fluid or fluent material includes continuously providing at least two sheets of bondable material having a fluid or fluent material therebetween, applying pressure to a transverse bond area of the bondable material to force the fluid or fluent material away from the transverse bond area, and heating the transverse bond area to form a seal.

A method for producing a vehicle component from a fiber-reinforced plastic including providing a skin panel having an inner side, outer side and mounting portion. The skin panel is a fiber-reinforced thermoplastic material. At least one stiffening component has a connection surface. The stiffening component is a fiber-reinforced thermoplastic material. The stiffening component and skin panel are contacted wherein the connection surface lies on the mounting portion. The method includes areally warming a joining zone so the stiffening component and skin panel are welded together. The joining zone is cooled. A determined geometry of the combination of stiffening component and skin panel is compared with a predefinable geometry. The joining zone is re-warmed, deforming the stiffening component and the skin panel, and the method includes cooling in order to attain the predefinable geometry if the determined geometry deviates from the predefinable geometry.

The present disclosure relates to a method for curing a heat-curable material (1) in an embedded curing zone (2) and an assembly resulting from such method. The method comprises providing a heat-conducting strip (3) partially arranged between a component (9) and a substrate (10) that form the embedded curing zone (2) therein between. The heat-conducting strip (3) extends from the embedded curing zone (2) to a radiation-accessible zone (7) that is distanced from the embedded curing zone (2) and at least partially free of the component (9) and the substrate (10). The method further comprises irradiating the heat-conducting strip (3) in the radiation-accessible zone (7) by means of electromagnetic radiation (6). Heat (4a) generated by absorption of the electromagnetic radiation (6) in the heat-conducting strip (3) is conducted from the radiation-accessible zone (7) along a length of the heat-conducting strip (3) to the embedded curing zone (2) to cure the heat-curable material (1) by conducted heat (4b) emanating from the heat-conducting strip (3) into the embedded curing zone (2).
