| 摘要 | Method and apparatus are disclosed for making the wire frames for strut type garment hangers in which the hanger hook portion is single stranded and the shoulder portions include oppositely facing side angle bends for insertion in the hanger tube or strut. Strands of wire are fed along a common axis toward each other from separate reels of wire. The ends of the wire strands enter means for forming the shoulders of the resulting hanger frame and for forming side angle bends and hooks at the shoulders and are cut to different lengths. After formation of the shoulders and side angle bends and hooks, the opposite ends of the previously cut wire strands are twisted together and the longer strand is bent to form the hanger hook. | ||||||
| 权利要求 | 1. A method of forming a resilient wire frame for a strut type garment hanger, comprising the steps of: A. cutting two lengths of essentially straight, flexible wire; B. bending the respective lengths of wire to an acute angle about a point near one end thereof; C. bending the one end of each length of wire out of the plane defined by the portions thereof on either side of the bend and back essentially upon and beneath itself; D. orienting the lengths of wire so that the one end of each length of wire faces oppositely to the other; E. twisting the other ends together to form a neck for the frame; and F. bending at least one of the other ends to form a hook for the frame. 2. An apparatus for forming a resilient wire frame for a strut-type garment hanger, comprising: A. means for providing first and second series of essentially straight, predetermined lengths of flexible wire; B. means for bending the respective lengths of wire from each series to an acute angle bend about a point near one end thereof to form shoulder portions of the hanger frame; C. means for bending the one end of each length of wire from the first series out of the plane defined by the portions thereof on either side of the bend and back essentially upon and beneath itself, to form a first strut engaging side angle bend and bottom hook; D. means for bending the one end of each length of wire from the second series out of the plane defined by the portions thereof on either side of the bend and back essentially upon and beneath itself, to form a second strut engaging side angle bend and bottom hook; whereby the first and second side angle bends and bottom hooks protrude from opposite sides of the finished hanger frame; E. means for twisting the other ends of lengths of wire from each source together to form a neck for the frame; and F. means for bending at least one of the other ends to form a hanger hook for the frame. 3. The apparatus of claim 2, wherein the means for providing lengths of wire comprises: A1. first and second sources of wire; A2. means for straightening and conveying the wire from the sources in axially opposite directions; A3. means for cutting the wire from the straightening and conveying means into predetermined lengths. 4. The apparatus of claim 2, wherein the means for bending each length of wire to an acute angle at one end comprises: B1. oppositely facing means for retaining each wire of each series near the one end thereof; B2. a curved wire forming surface located adjacent the retaining means; B3. roller means for bending the lengths of wire around the curved wire forming surface. 5. The apparatus of claim 2, wherein the means for forming the strut engaging side angle bends and bottom hooks comprise: C1. means for retaining each wire of the first series near the one end thereof; C2. a first forming surface having a first axis, for supporting each wire of the first series essentially along the axis of the first forming surface, and having a first leading edge beyond which the one end may extend; C3. a first side angle forming surface sloping downwardly and outwardly from the first forming surface, laterally away from the first axis and toward the first leading edge thereof; C4. a first cutaway portion located below the first leading edge of the first forming surface; and C5. first means for bending the wire along the first and side angle forming surfaces, around the first leading edge, and into the first cutaway portion, thereby to form a first strut engaging side angle bend and bottom hook; D1. means for retaining each wire of the second series near the one end thereof; D2. a second forming surface having a second axis, for supporting each wire of the second series essentially along the axis of the forming surface, and a leading edge beyond which the one end may extend in a direction axially opposite to the one end of the wires of the first series; D3. a second side angle forming surface sloping downwardly and outwardly from the second forming surface, laterally away from the second axis and toward the second leading edge thereof; D4. a second cutaway portion located below the second leading edge of the second forming surface; and D5. second means for bending the wire along the second and side angle forming surfaces, around the second leading edge and into the second cutaway portion, thereby to form a second strut engaging side angle bend and bottom hook. 6. The apparatus of claim 5, further including means for ejecting the completed first and second side angle bends and bottom hooks from contact with the various forming surfaces. 7. The apparatus of claim 5, wherein the first and second means for bending the wire along the first and second flat and sloping forming surfaces comprises an adjustable cam nut. |
