A binding lace for a novel automatic binder developed by the present inventors is disclosed. The binding lace is continuously thrusted from only one side of the binding lace into a lace guide positioned around an object to be bound and then travels while sliding along the lace guide without buckling to form loops of several turns overlapping each other. During travelling, the binding lace is sent in the lace guide without standing still, due to the properties of an outer portion and a core portion of the binding lace, while the binding lace always expands elastically outwardly in radial direction of the lace guide due to the larger rigidity and tensile stress of the core portion to hold a looped configuration with the loops having substantially the same diameter as the lace guide. After travelling stops, the binding lace is capable of holding the same diameter of the loops and a tip portion of the binding lace is held in the neighborhood of the overlap of the loops. The binding lace is pulled back to wind around the material to be bound. It has sufficient friction and elasticity in the outer portion of the binding lace, so that the tip portion of the binding lace is held by the bound material and at least one loop of the lace. In addition, the binding lace exerts a large tightening force by the core portion thereof, sufficient for binding a bundle of electric wires and gives a stable binding condition for a long time due to the outer portion thereof. |
