A fiber placement system including a compaction roller rotatable about an axis of rotation, the compaction roller including a reflective layer that includes a reflective material dispersed in a polymeric material, and a light source positioned to project a beam of electromagnetic radiation proximate the compaction roller, the beam having a wavelength, wherein the reflective material has a reflectance of at least 80 percent at the wavelength.

The problem to be solved by the invention is to provide a method for producing a joined body that reduces springback and can maintain high joining strength. The above problem is solved by a method for producing a joined body. The method includes heating a contact expected surface (a) of a molded body (A) containing carbon fibers and a thermoplastic resin, brining the heated contact expected surface (a) into contact with a contact expected surface (b) of a molded body (B) containing a thermoplastic resin; and joining the molded body (A) and the molded body (B). Contact surfaces (c) formed by contacting the contact expected surface (a) with the contact expected surface (b) includes a three-dimensional curved surface. The contact expected surface (a) is heated by using an infrared radiation mechanism capable of selectively infrared radiating the contact expected surface (a).

The present invention relates to method of manufacturing a fluid guiding assembly for a drug delivery device and to a respective fluid guiding assembly. Said method comprising the steps of: providing a first member having at least one recess in a first surface portion, at least partially filling the recess with a joining component at least partially protruding from the first surface portion of the first member, arranging a second member having a second surface portion adjacent to the first member such that first and second surface portions thereof face towards each other to form an interface area between the first and the second members, wherein the joining component comprises a material different to the material of the first and/or second member wherein at least one channel structure extending along the interface area is formed by at least one deepening of the first member and/or of the second member, selectively providing thermal energy to the joining component to bond together first and second members.

The present invention relates to a method for interconnecting components of a sporting good, in particular a sports shoe, and a sports shoe manufactured with such a method. The method may include (a.) forming a pattern element having at least one removable at least partially non-transparent or non-reflective portion, (b.) irradiating at least one of the first and the second component via the pattern element with heat radiation and (c.) interconnecting the irradiated first and second component.
