Abstract
A process and device for manufacturing, composite sections, by means of extrusion, are described. The composite sections comprise at least two components one of which is fed into the stream of metal being extruded and is securely joined to the face of the product without coming into contact with the face of the extrusion die.
Claims18
An extrusion process for manufacturing composite sections or similar items including at least two components, said process comprising the steps of:
- supplying metal to an extrusion die;
- supplying separately two flat metal strips to said die for extrusion along with said metal, said metal strips being supplied in face to face contact with each other and with their other respective faces contacting said metal, whereby each of said metal strips is joined to said metal during the extrusion but not to each other;
- and, separating the composite sections.
In an extrusion device for manufacturing composite sections including at least a metal and two flat metal strips, and comprising an entry plate, a mandrel plate, and a die plate having a die opening defined therein with short and long axes, the improvement comprising:
- two substantially symmetrical feeding channels for feeding in said metal strips defined by at least some of said plates, said feeding channels extending through said mandrel plate and uniting unobstructedly thereby defining a passageway extending substantially parallel to said short axis at said die opening and opening into said die plate, whereby said metal and said metal strips are separate in said entry plate and said mandrel plate and contact each other in said die opening.
