Patent abstract

A leno device uses the link mechanisms (31, 31′) to derive the movement of its half shaft (28) from the movement of its pull or lifting shafts (2, 3). The link mechanisms (31, 31′) connect the shaft rods (4, 5) of the pull or lifting shafts (2, 3) to the half shaft (28), whereby a connecting rod (32, 32′) extends between the two pull or lifting shafts (2, 3) from the top to the bottom through said shafts. The upper end of the connecting rod (32, 32′) is connected, on both sides of the connecting rod (32 32′) via connecting levers (33, 34, 33′ 34′), to the joints (36, 37, 36′, 37′) that are connected to the upper shaft rods (4, 5) of the pull or lifting shafts (2, 3).
