A DRAWING DEVICE FOR CONTROLLING THE HEDDLE FRAMES OF A LOOM, A SHED-FORMER ASSEMBLY INCLUDING SUCH A DEVICE, AND A LOOM FITTED WITH SUCH AN ASSEMBLY

摘要

In this drawing device (40) for controlling heddle frames (1) of a loom (M), a superstructure (30) supports rocker levers (41, 42). Each heddle frame (1) is driven by two rods (43, 44) driven by a pair of rocker levers (41, 42). A first rocker lever (41) is connected via a primary rod (47) to an outlet arm (52) of the shed-former machine (50). A second rocker lever (42) is connected to the first rocker lever (41) by a connecting rod (45). Each rocker lever (41, 42) is mounted to pivot relative to the superstructure (30) about an axis (Xx, X2) perpendicular to the travel direction (F of the heddle frames (1). For each pair of rocker levers (41, 42), the pivot axis (X^ of the first rocker lever (41) is higher (Hi H2) than the pivot axis (X2) of the second rocker lever (42).
