A series of elastic break brakes are provided throughout a travel path of elastics in a machine operation. Elastic strands thread through each individual brake mechanism, and if an elastic strand breaks downstream, a natural snap back of the elastic, which ordinarily travels through the system under tension, drives an immediately upstream cam mechanism back, and holds the elastic thread in place at the elastic break brake immediately upstream of the break as to minimize rethreading required downstream of the elastic break brake.

A lead wire storage mechanism stores most of a lead wire such that the lead wire can be taken out from a tip end portion. A tension adjusting mechanism including a dancer roller and two lifting and lowering guide rollers is formed with a partial space that is to be a part of a hand travel space at a time of a preparation state. A lead wire guide mechanism including an opening and closing lead guide is formed with a partial space that is to be a part of the hand travel space at the time of the preparation state. A lead wire grasping and moving mechanism can execute a grasping operation for grasping a tip end portion of the lead wire with a grasping part, and a grasping part moving operation for moving the grasping part through the hand travel space.

Provided is a screening apparatus or the like of an optical fiber that can suppress or prevent occurrence of a fiber-strike on the side of a feeding bobbin regardless of the weight of the feeding bobbin. An embodiment has a feeding bobbin 12 that feeds out an optical fiber 10; a screening unit 16 that applies a tension to the optical fiber 10 fed out from the feeding bobbin 12; a first capstan 14 that feeds the optical fiber 10 into the screening unit 16; a winding bobbin 20 that winds the optical fiber 10 to which the tension is applied by the screening unit 16; and a control unit 70 that, when disconnection of the optical fiber 10 occurs due to the tension applied by the screening unit 16, controls the feeding bobbin 12 and the first capstan 14 so as to stop rotation of the feeding bobbin 12 and rotation of the first capstan 14 and sets a deceleration rate of the first capstan 14 in accordance with a deceleration rate of the feeding bobbin 12.
