Apparatus for bonding discrete optical fibers into a ribbon

A tool for forming a plurality of discrete optical fibers into a ribbon format, comprising:

• a base member having a planar work surface;
• a first shim affixed to said work surface of said base member, said first shim having a straight edge;
• a second shim slidably attached to said work surface of said base member, said second shim having a straight edge which is generally parallel to and proximate said straight edge of said first shim;
• means for biasing said second shim toward said first shim;
• a first rail member attached to said first shim, said first rail member being generally parallel with said straight edge of said first shim;
• a second rail member attached to said second shim, said second rail member being generally parallel with said straight edge of said second shim, and said second rail member being located at a distance from said straight edge of said second shim which is approximately equal to the distance from said first rail member to said straight edge of said first shim;
• a blade holder having a groove for resting on either of said first or second rail members;
• and
• a blade attached to said blade holder, said blade having a cutting edge spaced from said groove sufficiently to bias said cutting edge against said straight edge of said first shim.

A kit for converting a plurality of discrete optical fibers into a fiber ribbon, comprising:

• a tool comprising
• a generally rectangular base having a work surface and a lower surface, and having an opening therein,
• a first shim affixed to said work surface of said base member, said first shim having a straight edge, said straight edge terminating in ramp-defining curved portions,
• a second shim, essentially identical to said first shim, slidably attached to said work surface of said base member, said second shim having a straight edge which is generally parallel to and proximate said straight edge of said first shim, said straight edge of said second shim also terminating in ramp-defining curved portions, said second shim further having a pin extending through said opening of said base, said first and second shims having a thickness which is approximately equal to the diameter of the optical fibers, and having a hole at each end thereof,
• a spring having first and second ends, said first end being attached to said pin of said second shim, and said second end being attached to said lower surface of said base;
• a first rail attached to said first shim, said first rail member being generally parallel with said straight edge of said first shim;
• a second rail, essentially identical to said first rail, attached to said second shim, said second rail member being generally parallel with said straight edge of said second shim, and said second rail member having a width which is approximately equal to the width of said first rail member, and being located at a distance from said straight edge of said second shim which is approximately equal to the distance from said first rail member to said straight edge of said first shim,
• means for retaining said second shim in a retracted position away from said first shim,
• first and second arm members, said first arm member being pivotally attached to said base proximate a first end thereof, and said second arm member being pivotally attached to said base proximate a second end thereof,
• a blade holder having a groove for resting on either of said first or second rail members, said groove having a width which is slightly larger than said width of said first rail member, and
• a flexible blade attached to said blade holder, said blade having a beveled cutting edge whose distance from said groove is slightly less than said distance from said first rail member to said first straight edge of said first shim;
• a plurality of strips of tape, each said strip having a length which is slightly shorter than the length of said straight edges of said first and second shims, and having a width which is no wider than the distance between said first and second rails when said second shim is in said retracted position;
• and
• tweezer means for removing excess tape from said shims, said excess tape being trimmed from one of said strips of tape applied to optical fibers lying between said shims.

A device for uniting a plurality of individual fibers into a ribbon comprising:

• a base member having a work surface;
• a first plate member having a straight edge, said first plate member being affixed to said work surface of said base member;
• a second plate member having a straight edge, said second plate member being slidably attached to said work surface of said base member, and said straight edge of said second plate member being approximate said straight edge of said first plate member;
• means for biasing said second plate member toward said first plate member;
• and
• means for retaining the fibers on said work surface said retaining means including first and second arm members, said first arm member being attached to said base member proximate a first end of said first plate member, and said second arm member being attached to said base member proximate a second end of said first plate member.
