50 Patent-Ansprüche:50 patent claims:1. Verfahren zur Herstellung von I-Trägern
mit parallelen Flanschen, dadurch gekennzeichnet, daß man die Flanschen eines Trägers mit konischen Flanschen in
einem mit parallelflächigen Walzen versehenen Universalwalzwerk von den Flanschkanten
aus staucht, bis die Zwischenräume zwischen den parallelflächigen Walzen ausgefüllt
sind.1. Process for the production of I-beams
with parallel flanges, characterized in that the flanges of a beam with conical flanges are in
a universal rolling mill with parallel-faced rollers from the flange edges
from upsets until the spaces between the parallel-faced rollers are filled
are.2. Eine Ausführungsform des Verfahrens nach Anspruch 1, dadurch gekennzeichnet,
daß man an dem Vorprofil die Kanten der Flanschen nach außen abschrägt oder abrundet, um bei der Umwandlung der
konischen Flansche in parallelflächige Flanschen eine Gratbildung zu vermeiden.2. An embodiment of the method according to claim 1, characterized in that
that on the preliminary profile, the edges of the flanges beveled or rounded to the outside in order to convert the
conical flanges in parallel flanges to avoid the formation of burrs.
Process for the production of packages from a number of plates which are lined up on one or more carriers and are held at a certain distance from one another by deformation of the carrier material, the plates or both, in particular for the production of electrical capacitors
