Abstract

Předmětem řešení je lamela (1) pro lamelový expandér, přičemž tato lamela (1) je čtvercového nebo obdélníkového tvaru vymezujícího: vnitřní stranu (11), vnější kontaktní stranu (12) a dvě boční strany (13). V lamele (1) je ve vnitřní straně (11) umístěn alespoň jeden zářez (14) obsahující obloukovou část (18). Zářez (14) je zakončen eliptickou nebo kruhovou dutinou (15), přičemž šířka dutiny (15) je větší než šířka zářezu (14). Předmětem řešení je také lamelový expandér obsahující alespoň dvě tyto lamely (1).
