  • Patent number: 7278285
    Abstract: A forming device having a rotating frame (1) and a forming blade (2) movable in the axial and radial directions of the rotating frame. One side-edge portion of a tubular blank (B) is fixed to a predetermined position of the rotating frame (1), and the other side-edge portion is movably set on the rotating frame. While the rotating frame (1) is rotated, the forming blade (2) is pressed to the inner diameter side or the outer diameter side of a peripheral wall of the tubular blank (B). The forming blade is reciprocated from the fixed side-edge portion radially outward or inward and moved toward the movable side-edge portion. Thus, a tubular formed body in which at least a ridge portion or a recess portion continuing in circumferential direction is shaped in the peripheral wall is formed.

  • Patent number: 7275567
    Abstract: A front end of a loop of a wire fed out to a nose (6) by a binding wire feeding mechanism (1) is pinched by a clamp plate (28) of a binding wire clamping apparatus (25) and the wire is pulled back by driving to rotate reversely a feeding motor (13) of the binding wire feeding mechanism (1). When the wire is brought into close contact with a reinforcing bar (S) and a load of the feeding motor is increased to thereby increase a drive current by a constant amount, a control apparatus stops the feeding motor. Thereafter, the binding wire clamping apparatus (25) is rotated to twist the binding wire to bind the reinforcing bar. Since the wire is pulled back and a length of the wire is automatically adjusted in accordance with a diameter of the reinforcing bar, a state of finishing to bind the reinforcing bar is made to be uniform and also an amount of consuming the wire is reduced.

  • Patent number: 7267142
    Abstract: The present invention relates to a method wherein a first end and a second end of a pre-tensioned spring are positioned against a first and second stop. A rotating body is first rotated about its longitudinal axis such that the first end engages once in a cam wheel during each rotation, the wheel having at least X+1 teeth and at least one cam that runs parallel with the teeth. The cam wheel thus rotates one tooth further with each rotation of the rotating body. The rotating body is subsequently subjected to pre-tensioning until the cam wheel and its cam lies against a third stop and the first end engages the cam wheel. The rotation is then continued in order to increase the torque.

  • Patent number: 7263868
    Abstract: A reforming assembly for simultaneously reforming and reprofiling a bottom portion of a metallic container is provided. The reforming assembly generally includes a roller block having a pair of reform rollers and two pairs of outside reprofile rollers. A biasing means is operably interconnected to the reform rollers, such that the reform rollers extend to contact the inner surface of the bottom portion of the container when contacted by the bottom portion of the container. The outside reprofile rollers engage with an outer surface of the bottom portion of the container. The container reforming assembly is rotated, while maintaining the container body in a static non-rotating position, to create an internal can profile on the inner surface by the pair of reform rollers, and an external can profile on the outer surface by the outside reprofile rollers.
