A manufacturing method and apparatus for manufacturing a coated optical fiber which has a superior surface smoothness of a resin coating and which can be coated with a colored ink with high coating performance. In the method including the steps of making a coated optical fiber by forming an outer coating layer around a bare optical fiber; and winding the coated optical fiber via pulleys by a take-up, the surface roughness of each solid body which the outer layer of the running coated optical fiber contacts is 0.8 nullm or less. When the temperature of the outer coating layer is a room temperature or the Young's modulus of the outer coating layer is higher than 500 MPa, the surface roughness of each solid body, which the outer layer of the coated optical fiber contacts during drawing or rewinding, is 1.2 nullm or less.

A radially expandable endcap adapted for mounting upon a mandrel of a collet of a forming package winder. Other aspects of this invention include a collet and winder including the above endcap and method for winding strand using the same. Another aspect of the present invention is a collet having an expandable mandrel on at least a portion of a first end of the collet proximate an operator and distal to a second, opposite end of the collet mounted upon a support. Other aspects of this invention are a winder including the above collet and a method for using the same.

A method of collecting strand includes rotating a collet to wind the strand into a package, traversing the strand from end to end of the package so that the strand is wound in a helical pattern on the package, contacting the package with a roller bail at edge portions at each end of the package, pressing the package with the roller bails, thereby causing the strand to flatten as it is wound in the edge portions to create a strand having periodically occurring flat spots, and controlling the flattening of the strand by controlling the pressure of the roller bails on the package. The flattening of the strand can also be controlled by controlling speed of the traverse of the strand.

A system and process for winding and mechanically transporting a wound package includes: (a) a plurality of fibers; (b) a guide for gathering the fibers to form a bundle; (c) a winder having a rotatable package collector and an apparatus for rotating the package collector about a stationary generally vertical axis; and (d) a mechanical transport for receiving the wound package from the package collector and transporting the wound package from a first position to a second position horizontally spaced apart from the first position.
摘要:
An optical fiber canister (20) is formed of a bobbin (22) having an optical fiber (24) wound in a plurality of layers. The optical fiber layers include a first layer (42) having a plurality of spaced-apart helical wound segments (44), with each pair of helical wound segments (44) being separated by a stepforward wound segment (46). A second layer (50) overlies the first layer (42), the second layer (50) comprising a plurality of spaced-apart helical wound segments (52), with each pair of helical wound segments (52) being separated by a stepforward wound segment (54). The first and second layers (42 and 50) are wound such that the stepforward wound segments (54) of the second layer (50) overlie the helical wound segments (44) of the first layer (42), and the helical wound segments (52) of the second layer (50) overlie the stepforward wound segments (46) of the first layer (42).
摘要:
The present invention is directed to a system for sensing and correcting the alignment of a mandrel being wound with filamentary material with respect to the filamentary material winding mechanism. A positioned reference pin attached to the mandrel is positioned in a beam of collimated light emanating from a laser so as to bisect the light beam and create a shadow therebetween. A pair of photocells are positioned to receive the bisected light beam with the shadow uniformly located between the photocells when the pin is in a selected position. The mandrel is supported in the selected position for the winding of a filamentary material by a position adjustable roller mechanism which is coupled by a screw drive to a reversible motor. Changes in the pin position such as caused by winding growth are sensed by the photocells to provide the displacement of the roller mechanism in the direction necessary to return the mandrel to the selected position.
摘要:
A method of and apparatus for monitoring the method comprising the steps of: generating electromagnetic radiation; using a first lens to form the electromagnetic radiation into a beam; directing the beam through a sampling volume for impingement upon the fibers; positioning a second lens in the same horizontal plane as the first lens such that the angle, whose tangent is D/d, is greater than or equal to five degrees, where D is the diameter of the second lens and d is the distance from a plane through the center of the second lens to the center of the sampling volume; collecting electromagnetic radiation backscattered from the fibers by means of the second lens; and generating a signal responsive to the amount of radiation collected as an indication of the average diameter of the fibers.
摘要:
The disclosure embraces a method of and apparatus for processing fibers or filaments of glass or other fiber-forming material into a roving and packaging the roving, the fibers or filaments during advancement being initially separated or segregated into strands or linear groups of fibers or filaments by fine streams or jets of air or other gas, maintaining the strands in separated condition by a guide, converging the separated strands into a roving and winding the roving into a package.
