Method for manufacturing protection sleeves

A method for manufacturing a plurality of protection sleeves, the method comprising:

• providing a plurality of heat shrinkable tubes, each heat shrinkable tube having a hollow interior;
• inserting a hot melt adhesive tube and a reinforcing rod into the hollow interior each of plurality of the heat shrinkable tubes, the hot melt adhesive tubes also having hollow interiors;
• retaining the plurality of heat shrinkable tubes on a jig parallel to one another and spaced apart from one another, with the reinforcing rods being positioned below the hot melt adhesive tube within each of the plurality of heat shrinkable tubes;
• simultaneously heating the plurality of heat shrinkable tubes for a first predetermined period of time such that the heat shrinkable tubes provisionally shrink in order to hold the reinforcing rod in position within respective ones of the heat shrinkable tube;
• re-positioning the plurality of heat shrinkable tubes to a second distance away from the heating device, the second distance being less than the first distance;
• and
• heating the plurality of heat shrinkable tubes for a second predetermined period of time at the second distance such that a middle portion of each of the hot melt adhesive tubes melts within respective ones of the heat shrinkable tubes adhering to the reinforcing rods and an interior surface of the heat shrinkable tubes, such that the hollow interior of the hot melt adhesive tube has a sufficient opening for an optical fiber to pass therethrough.
