摘要:
The invention relates to an activation device for a device for applying edge strips (1), which can be heat-activated without an adhesive in particular, onto plate-like workpieces, having at least one hot gas inlet (9) for supplying heated and pressurized hot gas (12) into an activation chamber (26), in which the hot gas (12) heats the heat-activatable layer of the edge strip (1), and at least one catching device (8) for catching and discharging the heated hot gas (12) from the activation chamber (26). The activation chamber (26) is bordered such that the hot gas (12) flowing through the activation chamber (26) is conducted from the hot gas inlet (9) to the catching device (8) for the hot gas (12) almost completely within the activation chamber (26) without being able to exit the activation chamber (26).
摘要:
The invention relates to an edge coating device (1) for applying a ribbon-shaped edge strip (4) to narrow surfaces (6) of a workpiece (5), wherein the edge strip (4) can be fastened by heat activation to the narrow surfaces (6), in particular in multiple layers without adhesive or with a hot melt adhesive layer between edge strip (4) and narrow surface (6). The device comprises at least one feed device (7) for the edge strip (4) and a pressing device (9) that presses the heat-activated edge strip (4) against the narrow surface (6) of the workpiece (5). In the case of said edge coating device (1) and the corresponding coating method, an outlet (10) for hot air (16) is arranged in the region of the feed device (7) and/or pressing device (9). The opening applies the hot air (16) under a pressure of one bar or more onto the edge strip (4) and/or onto the heat-activatable layer of the edge strip (4) and/or onto the narrow surface (6) of the workpiece (5), wherein a heating device (3) is in fluidic connection for the hot air with the outlet (10). The heating device (3) brings the hot air (16) to the required activation temperature for the heat-activatable layer of the edge strip (4) or the hot melt adhesive.
摘要:
Die Erfindung betrifft eine Isolierung für mit Heißgas in Berührung kommende Teile einer Schmalflächenbeschichtungsvorrichtung, insbesondere für schlauch- oder rohrförmige Führungen für Heißgas, bei der die Isolierung hochporöse oder mikroporöse Materialien, insbesondere Aerogel, vorzugsweise Aerogel auf Silikatbasis aufweist. Weiterhin wird eine entsprechende schlauch- oder rohrförmige Führung für Heißgas an einer Schmalflächenbeschichtungsvorrichtung vorgeschlagen.
