Abstract
Apparatus capable of bending laces in a continuous manner. A lace material is supplied from a material feed device and allowed to pass through a fixed guide roller element for locating the material and a movable guide roller element for bending the material. The guide roller element for bending the material can move in directions perpendicular to the direction of supply of the material in relation to the fixed guide roller element for locating the material. When passing through these guide roller elements, the material can be bent in accordance with the speed of supply or feed of the material and the moving amount of the movable guide roller element so that desired radii of curvature are given to the material.
