Abstract
An apparatus for producing optical fiber ribbons which has a optical fiber gathering device, one or more coating applicators and a turn roller arranged in a straight line, with one or more alignment guide in plate form being provided on a travelling line of optical fibers or optical fiber ribbons upstream of the coating applicator. The alignment guide is chamfered to arch form on the side that contacts the optical fibers or the optical fiber ribbons. The alignment guide suppresses the optical fibers or the optical fiber ribbons from vibrating in a direction perpendicular to the direction of the arrangement of the optical fibers or the optical fiber ribbons.
Claims9
A method of producing an optical fiber ribbons utilizing an apparatus for producing an optical fiber ribbon, comprising an optical fiber gathering device, one or more coating applicators, and a turn roller, all of which are arranged in a straight travelling line of optical fibers or optical fiber ribbons, and further comprising one or more alignment guides in a plate form which is chamfered to arch form on a side that contacts with said optical fibers or optical fiber ribbons, each alignment guide being positioned upstream of each coating applicator on said travelling line so as to prevent the optical fibers or the optical fiber ribbons from vibration in a direction perpendicular to a direction of arrangement thereof, said method comprising the steps of:
- suppressing the vibrations occurring in the direction perpendicular to the direction in which the optical fibers or optical fiber ribbons are arranged.
An apparatus for producing an optical fiber ribbon, comprising:
- an optical fiber gathering device;
- one or more coating applicators;
- and
- a turn roller, all of which are arranged in a straight travelling line of optical fibers or optical fiber ribbons, and further comprising one or more alignment guides in a plate form which is chamfered to arch form on a side adjacent the travelling line of said optical fibers or optical fiber ribbons being positioned upstream of each coating applicator on said travelling line so as to prevent the optical fibers or the optical fiber ribbons from vibration in a direction perpendicular to a direction of arrangement thereof.
An apparatus for producing an optical fiber ribbon, comprising:
- an optical fiber gathering device, one or more coating applicators, and a turn roller arranged to dispose optical fibers or optical fiber ribbons borne thereby in a substantially straight line between said optical fiber gathering device and said turn roller;
- and
- an alignment guide positioned immediately adjacent the optical fibers disposed in said substantially straight line between said optical fiber gathering device and said turn roller,
- wherein said alignment guide is positioned to form a gap between the optical fibers or optical fiber ribbons and the alignment guide, and
- wherein said gap corresponds in width to an amount less than or equal to an amplitude of vibration of said optical fibers or optical fiber ribbons at a point immediately adjacent said alignment guide.
