Abstract

Przedmiotem zgłoszenia jest sito perforowane w postaci płyty (1), w której znajdują się regularnie rozmieszczone rzędy jednakowych otworów (2), które charakteryzuje się tym, że każdy otwór (2) ma kształt epicykloidy opisanej równaniem przedstawionym wzorem A ze względu na ϕ, gdzie k=R/r=7, przy czym r oznacza promień okręgu otaczającego (3), R to promień okręgu nieruchomego (4), a k oznacza stosunek promienia okręgu nieruchomego (4) do promienia okręgu otaczającego (3). Otwory (2) w następujących po sobie rzędach obrócone są względem osi otworu (2) o 180°.The subject of the application is a perforated screen in the form of a plate (1) in which there are regularly spaced rows of identical holes (2), which is characterized in that each hole (2) has the shape of an epicycloid described by the equation presented in formula A with respect to ϕ, where k=R/r=7, where r is the radius of the surrounding circle (3), R is the radius of the stationary circle (4), and k is the ratio of the radius of the stationary circle (4) to the radius of the surrounding circle (3). The holes (2) in successive rows are rotated with respect to the axis of the hole (2) by 180°.
