20100077821 | DUCT MAKING APPARATUS AND METHOD - A duct making apparatus bends a metal web to form a duct blank having a lock tab at a forward end and having a Z-fold at a rearward end. Prior to shearing off the duct blank from the metal web, the apparatus bends the duct blank to insert the lock tab into the Z-fold, and further bends the Z-fold to form a clinch tab holding the lock tab into the Z-fold. After shearing off the duct blank from the metal web, the apparatus clinches the clinch tab over the lock tab to form a completed duct blank. | 04-01-2010 |

20110030435 | Bending Method And Bending Apparatus For Medical Suturing Needle - Provided are a bending method and a bending apparatus for bending a medical suturing needle into different curved shapes by using one bending top. The bending apparatus comprises a reciprocally rotatable bending top, and a belt having such a flexibility as can be wound on the outer circumference of the bending top. The bending method curves a medical suturing needle by sandwiching and constricting a material for the medical suturing needle between the bending top and the belt and by rotating the bending top reciprocally in the winding direction and in the rewinding direction. In the bending method, the curved shape of the material is changed by changing the winding angle of the belt to be wound on the outer circumference of the bending top thereby to change the area for constricting the material. The bending apparatus (B) comprises a reciprocally rotatable bending top ( | 02-10-2011 |
20110174037 | METHOD AND APPARATUS FOR MANUFACTURING STATOR COIL FOR ELECTRIC ROTATING MACHINE - A method of manufacturing a stator coil for an electric rotating machine includes the steps of: (1) forming substantially planar electric wires each of which includes in-slot portions to be received in slots of a stator core and turn portions to be located outside the slots to connect adjacent pairs of the in-slot portions; (2) rolling each of the planar electric wires through plastic deformation into a spiral or circular-arc shape; and (3) assembling the rolled electric wires together to form the stator coil. Further, in the rolling step, each of the planar electric wires is rolled by deforming each of the turn portions of the electric wire while restricting movement of at least one of the in-slot portions of the electric wire which is located closer to a rolling start end of the electric wire than the turn portion is. | 07-21-2011 |

20130025339 | Apparatus and Method for Forming a Wave Form for a Stent from a Wire - An apparatus for forming a wave form for a stent from a wire includes a pair of tension wires configured to rotate about an axis. The tension wires and axis are substantially orthogonal to the stent wire disposed in a gap between the tension wires. When the tension wires are rotated, a bend is formed in the portion of the stent wire disposed between the tension wires. The tension wires may be controlled such that the axis of rotation is aligned with the particular tension wire around which the stent wire is to be bent for each particular bend formed in the stent wire, thereby preventing the particular tension wire from translating during rotation such that the tension wire behaves like a rotary pipe bending die around which the stent wire is bent. A feed assembly feeds the stent wire into the forming area between the tension wires. | 01-31-2013 |
