摘要:
Plant for making decorations on a bituminous membrane (M) comprising feed means (35) configured to feed the bituminous membrane (M) at a determinate speed in a direction (Z), and at least two depositing apparatuses (11, 12, 13) disposed one in series with the other in the direction (Z) and configured to deposit solid particles (P1, P2, P3) on said bituminous membrane (M) according to respective patterns in order to obtain respective decorations (14, 15, 16) on the bituminous membrane (M). The depositing apparatuses (11, 12, 13) each comprising a transfer member (17, 18, 19) configured to receive, support and transfer the solid particles (P1, P2, P3) from a respective feed device (20, 21, 22), to the surface to be enhanced of the bituminous membrane (M).
摘要:
Vorrichtung zum intermittierenden Beschichten eines relativ zur Vorrichtung in einer Transportrichtung (U) in Bewegung befindlichen Substrats (170), umfassend einen Düsenkörper (100) mit einem Zulaufkanal (107) und mindestens zwei Düsenbacken (101,102), zwischen denen eine Einlagefolie (108) mit einer Aussparung vorgesehen ist, welche einen Düsenschlitz (103) bildet, der quer zur Transportrichtung (U) und parallel zum Substrat (170) erstreckend in einem Austrittsspalts (130) endet, wobei wenigstens eine Düsenbacke (101,102) mit mindestens einem Durchbruch (123) versehen ist, der zwischen einem Zulaufkanal (107) und dem Austrittsspalt (130) in den Düsenschlitz (103) ausmündet und mit einem elastischen verformbaren Element (121) fluiddichtend zum Düsenschlitz (103) hin verschlossen ist. Der Durchbruch (123) ist mit einer Abdeckung (126) versehen, welche mit dem elastisch verformbaren Element (121) eine Druckammer (128) für die Aufnahme eines Hilfsfluides ausbildet und die Druckammer (128) fluiddichtend gegenüber der Umgebung verschließt.
摘要:
The invention relates to a device (100) for applying a material strand to an object, which material strand is intended for the production of an element for electromagnetic shielding. The device (100) comprises a first cylinder (120), which is arranged to accommodate a dispensable first material, a second cylinder (122), which is arranged to accommodate a dispensable second material, and a piston (130, 132) in respectively the first (120) and the second cylinder (122), which pistons (130, 132) are arranged movably in the respective cylinder (120, 122). The device (100) further comprises a drive member having a piston unit (190) for unison displacement of the pistons (130, 132) in order to achieve respectively a first flow of the first material from the first cylinder (120) and a second flow of the second material from the second cylinder (122), a merging unit for merging the first and the second flow into a merged flow in which the first flow flows around the outside of the second flow, and a dispensing nozzle (118) for dispensing the merged flow onto the object in order to achieve the material strand. The invention also relates to a method for applying the material strand.
