The present invention relates to a method for manufacturing a crossbeam for a heddle frame of a loom allowing to make, at low cost and without waste, a lightweight and very rigid crossbeam, whose heddle-support rod is positioned on the support section in an accurate position that is completely linear, controlled and capable of being reproduced. This manufacturing method is characterized in that one uses a rigid model that has at least one rectilinear groove having a width substantially equal to that of the heddle-support rod; one positions the non-rigid heddle-support rod in the groove to make it rectilinear; one lays a glue line on the junction zone; one positions a rigid support section that is not necessarily rectilinear in a predetermined manner on the model and on the heddle-support rod by flattening the glue line, and one maintains the support section and the heddle-support rod integral with the model, at least while the glue is setting.
Method for manufacturing a crossbeam (2, 2′) for a heddle frame (1) of a loom, said crossbeam (2, 2′) comprising at least one support section (3, 3′) and at least one heddle-support rod (4, 4′) affixed to said support section (3, 3′) along a junction zone (40, 40′), wherein one uses a rigid model (7) comprising at least one first rectilinear groove (70) having a width substantially equal to that of the heddle-support rod (4, 4′);
