摘要： A method for loading a layer of aluminium alloy longitudinal profiles onto a support comprising the steps of:
-positioning said layer of longitudinal profiles on a predetermined rest means (20);
-grasping, at two opposite ends, said layer (10) of longitudinal profiles by means of first and second gripping means (51, 52);
-displacing said layer from said rest means (20) making said layer assume a deformed configuration in which: the first and second gripping means (51, 52) grasp the two corresponding opposite ends of the layer, the layer in an intermediate area between the first and the second gripping means (51, 52) undergoing by gravity a deformation that defines a concavity facing upwards;
-positioning a compensation means (6) for compensating for the deformation of the longitudinal profiles in an intermediate area between the first and the second gripping means (51, 52);
-moving the first and second gripping means (51, 52) and said compensation means (6) positioning said layer of profiles above said support.

摘要： L'invention concerne une méthode et un dispositif de filage direct lubrifié des métaux et alliages avec chemisage avant radial.
La méthode selon l'invention consiste à ménager un interstice (6) en forme de couronne circulaire plane ou de forme légèrement tronconique, d'épaisseur constante (j) et de portée (h), ouvert à l'air libre, entre l'extrémité du conteneur (1) adjacente à son alésage et.l'ensemble des outillages de filage (4, 5) situés en vis-à-vis.
Pour faciliter la formation et surtout l'extraction de la chemise (8), le dispositif de filage comporte plusieurs couteaux (11), situés dans l'interstice (6) décrit ci-dessus, dont l'arête (15) est dirigée vers l'axe (7) du conteneur (1) et qui divisent la chemise (8) en autant de "pétales" en cours de filage.

摘要： Twin metal billets (31) are fed to dual circumferential grooves (44) formed in a rotary wheel (43), and are advanced to a die (21) which has a die opening with a circumferentially discontinuous, annular cross section. The metal merges in the die opening and exits therefrom in the form of a slit tube (34, 36). The tube is advanced over a forming member (38) to form a flat strip (39). As the tube is advanced over the forming member, an alignment system (300) maintains the tube in a centred position. The alignment system includes a light source (302a, b) disposed within the tube and two arrays of photo-transistors (308) arranged to receive light from the light source, the amount of light sensed by each array being a function of the position of the slit in the tube relative to a desired position. Any difference results in a steering roll (318) in contact with the outer surface of the tube pivoting in a direction which will bring the tube back into alignment.

摘要： Verfahren zum Strangpressen eines Profiles od. dgl. Körpers aus einem Barren (24), der in einer Rezipientenbohrung (22) eines Aufnehmers (18) geführt und mittels eines Pressstempels (16) in Pressrichtung einem Formquerschnitt eines Formwerkzeuges (32) zugeführt wird. Vor Eintritt des Barrens (24) in den Formquerschnitt wird der Barren (24) in Pressrichtung um ein Kragmass aus dem Aufnehmer (18) geschoben. Danach wird ein dabei entstehender scheibenartiger Abschnitt (48) des freien Barrenendes abgeschert und entfernt sowie letzteres anschliessend an den Formquerschnitt gebracht. Vorteilhaft wird ein verbleibender Pressrest an der gegen die Pressrichtung weisenden Werkzeugfläche eines voraufgegangenen Barrens und der scheibenartige Abschnitt des freien Barrenendes zeitgleich abgeschert.

摘要： Twin metal billets (31) are fed to dual circumferential grooves (44) formed in a rotating wheel (43). The billets are advanced first to a edge-shaped gap which deforms the billets and are then advanced to a die (63). The die has a die opening with a circumferentially discontinuous, annular cross section. The metal from each billet merges in the die opening and exits therefrom in the form of a slit tube (34). The tube is then opened and flattened to form a flat strip (39) by advancing the slit tube over a forming member (38) having a progressively increasing width.
