Abstract
A sill (') for a lift door is manufactured with a method that includes the steps of providing at least one support element () and an upper profile () that defines at least a boundary surface () of a first groove longitudinal () for slidingly receiving a lift door. The support element () and the upper profile () are joined, placing a first demarcation profile (′) alongside the upper profile (), so that a boundary surface () of the first demarcation profile delimits part of the first longitudinal groove (). A sliding transversal cross-section of the first longitudinal groove () is adjusted by approaching/distancing the boundary surfaces () and, having obtained a desired sliding transversal cross-section, constraining the mutual position of the first demarcation profile (′) and of the upper profile ().
