A tape supply device that supplies a tape to an optical cable, the tape supply device includes: an accumulator unit of a multistage unit type divided into units, each of the units including a plurality of movable rollers and a plurality of fixed rollers, the units being connected in series; and a control unit configured to control a supply order of the tape from the units.
First claim
Opening claim text (preview).
What is claimed is: 1. A tape supply device that supplies a tape to an optical cable, the tape supply device comprising: an accumulator unit of a multistage unit type divided into units, each of the units including a plurality of movable rollers and a plurality of fixed rollers, the units being connected in series; and a control unit configured to control a supply order of the tape from the units, wherein each of the units includes a brake configured to stop the movable rollers, and when the units are switched, the control unit performs control such that the brakes of two of the units before and after the switching do not operate simultaneously. 2. The tape supply device according to claim 1 , wherein the tape is a longitudinal wrap tape. 3. The tape supply device according to claim 1 , wherein the movable rollers of each of the units are attached to a weight that controls tension of the tape, and the weight of each of the units differs in weight. 4. The tape supply device according to claim 1 , wherein the number of turns of the tape by the movable rollers and the fixed rollers of each of the units is five back-and-forth movements or less. 5. An optical cable manufacturing apparatus using the tape supply device according to claim 1 . 6. An optical cable manufacturing method using the tape supply device according to claim 1 .
