Including Varying Rate Of Shifting Of Stroke Limits Patents (Class 242/479)
  • Patent number: 8805151
    Abstract: A lashing assembly lashes together two or more fiber optic telecommunications cables. The lashing assembly comprises at least a first and a second bobbin. As the cables are passed through the first bobbin, twine pays off from the first bobbin and wraps around the cables in a clockwise helix. As the cables are passed through the second bobbin, twine pays off from the second bobbin and wraps around the cables in a counterclockwise helix. In this way, the twine from the first and second bobbins lash the cables together as the cables are passed through the first and second bobbins.

  • Patent number: 6634590
    Abstract: A method of forming a wound fiber package comprises winding a first portion of strand having at least one fiber on a bobbin using a first indexing ratio A:B, wherein A is greater than 0 and A is greater than B, and winding a second portion of strand having at least one fiber on the bobbin using a second indexing ratio A:B different from the first indexing ratio, wherein A and B are greater than 0. In one non-limiting embodiment of the invention, B equals 0 in the first indexing ratio, A in the first indexing ratio equals A in the second indexing ratio, and A equals B in the second indexing ratio. In another non-limiting embodiment of the invention, B is greater than 0 in the first indexing ratio, A in the first indexing ratio equals A in the second indexing ratio, and A equals B in the second indexing ratio. This method may be used to produce a wound package.

  • Patent number: 5924644
    Abstract: A process for producing different types of windings, especially a flyer winding or a composite winding, in the formation of a spool on a core sleeve of a spindle in a draft-twisting machine or frame in which, instead of displacing the ring rail over the full height of the spool to be formed, the full height is subdivided into zones and the ring rail is reciprocated in each of these zones only through a fraction of the total structure of the ring rail. During the winding in each zone, the spindle speed is held approximately constant and the spindle speed is changed only upon a transition from one zone to another.
