ARTIFICIAL TREE |
| 摘要 |
A method of forming artificial needles in an elongated planar strip of plastic material to be formed into artificial tree branches, comprises bending longitudinal edge portions of the strip out of the plane of the strip progressively along the length of the strip, and slitting longitudinal edge portions of the strip, including the bent portions of the strip and portions of the strip adjacent the bent portions, in a direction transverse to the length of the elongated strip, to form artificial needles. The strip is preferably advanced continuously along a bending tool to bend the longitudinal edge portion. The longitudinal edge portion of the strip may be heated prior to or during the bending of the edge portion to reduce spring back. |

1. A method of forming artificial needles in an elongated strip of plastic material to be formed into artificial tree branches, said method comprising
bending at least one of the longitudinal edge portions of said strip out of the plane of the strip progressively along the length of the strip, and slitting longitudinal edge portions of said strip, including the bent portions of said strip and portions of said strip adjacent said bent portions, in a direction transverse to the length of the elongated strip, to form artificial needles. |
