A multi-dimensional bending method and apparatus are disclosed, wherein the entire length of the product is divided into a plurality of imaginary segments which are identified by detecting the continuously supplied length of an elongate material. This material is bent multi-dimensionally by a bending device including horizontal and vertical bending mechanisms and an axial twisting mechanism having the respective actuators arranged remote from the movable elements of the mechanisms, and individually actuated in response to the detected supplied length of the material. Multi-dimensionally bent, continuously supplied material is cut into the length of the product by means of a cutting device also actuated in response to the detected supplied length of the material, and includes fixed and movable blade members which, during the cutting operation, and movable also in the direction in which the material is supplied. The cutting operation is effected without requiring an interruption of the continuous supply of the material.
An apparatus for producing multi-dimensionally bent articles, including a retaining device for laterally retaining a continuously supplied elongate material while permitting the material to slide longitudinally thereof, and a bending device arranged behind the retaining device, for multi-dimensionally bending the material, wherein the bending device comprises a base member, a bottom plate pivotably mounted on the base member so as to be angularly movable about a vertical axis, a vertical plate fixedly mounted on the bottom plate at right angle to the longitudinal axis of the material, horizontal bending means mounted on the vertical plate, for laterally retaining the material and permitting passage of the material therethrough, a vertical bending means arranged behind the horizontal bending means and pivotably mounted with respect to the vertical plate such that the vertical bending means is angularly movable about a horizontal axis.
An apparatus for producing multi-dimensionally bent articles, including a retaining device for laterally retaining a continuously supplied elongate material while permitting the material to slide longitudinally thereof, and a bending device arranged behind the retaining device, for multi-dimensionally bending the material, wherein the bending device comprises a base member, a bottom plate pivotably mounted on the base member so as to be angularly movable about a vertical axis, an actuator arranged below the base plate, for actuating the bottom plate about said vertical axis, said actuator comprising at least one actuator cylinder connected with the bottom plate through a conversion mechanism which converts the linear motion of the actuator cylinder into the angular motion of the bottom plate about said vertical axis, a vertical plate fixedly mounted on the bottom plate at right angle to the longitudinal axis of the material, horizontal bending means mounted on the vertical plate for laterally retaining the material and permitting passage of the material therethrough, and vertical bending means arranged behind the horizontal bending means and pivotably mounted with respect to the vertical plate such that the vertical bending means is angularly movable about a horizontal axis.
