Abstract: A system for the production of extruded aluminum or aluminum alloy profiles starting with billets has an extrusion press having a horizontally directed outlet and to which is fed preheated billets press such that the billets exit the outlet of press as a horizontally extending profile that is fed horizontal to a horizontal bench where, while still horizontal, the provides are cooled, straightened, and cut into profile sections. A conditioning chamber for profile ageing heat treatment downstream of the bench as well as a device for coating the profile sections. A device upstream of the conditioning chamber picks the profile sections up off the bench and shifts them from the horizontal orientation to a vertical orientation. An overhead conveyor extends from the picking-up device through the conditioning chamber and coating device for conveying the profile sections therethrough while in the vertical orientation.

Abstract: The invention concerns a system for the production of extruded aluminium or aluminium alloy profiles (17) starting from billets, which comprises, downstream at least a bench (16) for cooling, straightening (stretching) and cutting to size the profiles (17) which follows a reception line for the extruded profiles exiting from a press (11), a conditioning chamber (18) for profile ageing heat treatment, which is configured and equipped with means (19) for arranging, sustaining and moving the profiles, in continuous fashion, into vertical position during their treatment at controlled temperature and for a preset time.

Abstract: Rack (100) for stacking metal sections (105), comprising a plurality of mutually facing frames (110), each frame comprising at least one upright (115a, 115b) and a plurality of cross-pieces (120) extending from the at least one upright to define support surfaces for the sections, at least one further frame (205) associated with each frame, each further frame comprising at least one further upright (210a, 210b) and a plurality of further cross-pieces (215) extending from the at least one further upright and being movable between a rest position in which each further cross-piece is disposed at the same height as a corresponding cross-piece and a working position in which each further cross-piece is disposed at a different height to define further support surfaces for the sections, and means (225a, 225b) for securing the further frames in the rest position or in the working position.

Abstract: Description of an inkjet printing method, whereby a second and optionally a third and/or additional ink(s) is/are printed on top of each other or immediately next to each other, whereby (i) the first ink contains a coloring substance precipitable by a precipitation reagent, (ii) the first or the second ink contains the precipitation reagent in temporarily passivated form, and (iii) the first, second or third ink contains an activator for the temporarily passivated precipitation reagent, with the proviso that the temporarily passivated precipitation reagent and the activator are not present in the same ink. The method prevents or reduces the problem of mixing or running into each other of two inks at their border lines. The temporarily passivated precipitation agent can be a complexed multi-valent metal ion, which is displaced from the complex by the activator.

Abstract: An apparatus for the extrusion of profiles includes at least two rectilinear transport path for receiving extruded profiles and provided with clamping devices for clasping the leading and trailing ends respectively of respective extruded profiles. The two transport paths are carried by a drum-like rotatable support whereby each transport path can be moved from an extrusion position whereat an extruded profile can be received on the transport path, and a transfer position whereat the profile can be transferred from the transport path to another processing station, and further to the extrusion position.
