摘要： A dispensing system for dispensing a hot melt adhesive foam onto a substrate is described. The dispensing system comprises a pump having a first input to receive a hot melt adhesive and a second input to receive a gas, where the pump mixes the hot melt adhesive and the gas to produce a solution. The dispensing system also includes a temperature sensor to detect a temperature of the solution, a dispenser to receive the solution from the pump and dispense the solution, and a controller. The controller instructs the pump to operate at a first speed, receives the temperature of the solution, and instructs the pump to operate at a second speed that is different than the first speed in response to the signal.

摘要： A building panel has a deep drawn transparent film having an inner face and a structure having solar cells on the inner face of the deep-drawn film. The structure has an inner face turned away from the film and an outer face on or closely juxtaposed with the inner face of the film. A reinforcement layer constituted as a mass of foamed granular particles is spread over the inner face of the structure in direct contact with the inner face of the structure without the interposition of an adhesive and is heat cured to the film.

摘要： A method is disclosed for dispensing a polyurethane mixture onto a substrate by generating a liquid mixture from reactive component resins; introducing the mixture in an inlet section of a dispensing device so as to advance it towards a planar-shaped outlet slit section, transversely to the advancement direction of the substrate; distributing the mixture along a gap chamber having a cross section diverging towards the outlet slit section; and dispensing the mixture through the outlet slit section, so as to deposit a thin, uniform film onto the substrate. Fractions of the mixture travel equal distances from the inlet section to the outlet slit section, in equal times, maintaining equal average speeds along each section having zones placed all at the same path distance either from the inlet section or from the outlet slit section.

摘要： A method and device for manufacturing a sandwich structure comprising at least one foam layer of a first thermoplastic comprising a chemical blowing agent and two cover layers. The decomposition temperature of the chemical blowing agent is higher than the melting point or range of the first thermoplastic. The method comprises a series of steps performed on an advancing starting structure including heating under pressure in order to cause decomposition of the blowing agent, intermediate cooling, foaming at a constant volume and further cooling.

摘要： The invention relates to a casting device for applying a foaming reaction mixture, to at least a partial width of a cover layer, wherein the casting device comprises: a supply connection for feeding in the reaction mixture; at least one exit slit extending in a transverse direction for the exiting of the reaction mixture; two slit plates arranged opposite one another, wherein a slit space extends between the slit plates in a vertical direction above the exit slit. A supply channel connected to the supply connection is formed between the slit plates, which closes off the slit space above the exit slit in the vertical direction The supply channel has a channel cross-section, the main dimension of which is larger that the width of the slit space. The reaction mixture can be introduced into the slit space to distribute the reaction mixture over the length of the supply channel.
