Abstract
A system and method for manufacturing a honeycomb body is described provided. Said system having: a forming mold with a plurality of sub-molds, which are movable so that they can be opened and closed; a tightening mold for tightening said forming mold; rolling pin(s), which can be inserted into and pulled out of the inner volume of said forming mold and can rotate around a rotation axis; wherein said tightening mold has a shape that cooperates with the shape of said forming mold, so that an action of said tightening mold causes tightening of said forming mold.
Claims9
A system for manufacturing a honeycomb body, comprising:
- a forming mold with a plurality of sub-molds, which are movable so that they can be opened and closed;
- a tightening mold for tightening said forming mold;
- rolling pin(s), which can be inserted into and pulled out of the inner volume of said forming mold and can rotate around a rotation axis;
- wherein said tightening mold has a shape that cooperates with the shape of said forming mold, so that an action of said tightening mold causes tightening of said forming mold.
A method for manufacturing honeycomb body, wherein the system of one of the above claims is applied, the method comprising the following steps:
- opening the forming mold;
- introducing the foil stack into the space between the rolling pin;
- rotating the rolling pins until the foil stack is fully rolled into the forming mold;
- rotating the rolling pins while activating the tightening mold, with the action thereof causing the inner volume of the forming mold decreasing to a first value;
- pulling the rolling pins out of the structure formed by the foil stack;
- pushing the rolled-up honeycomb structure into a housing by means of the ejecting part.
