Cable tensioning based on load profiles is provided. A system can include a dispenser of a charger and one or more processors. The system can detect a characteristic of a vehicle. The system can determine, based at least in part on the characteristic of the vehicle, an amount of force to apply to a cable. The system can provide an instruction to cause the dispenser to apply the amount of force to the cable.

A method and system are provided for cutting and placing individual nose wires in a facemask production line. A continuous wire is supplied from a source to a cutting station in the production line. At the cutting station, the wire is engaged with a set of driven feed rollers that advance the wire at a first speed to a cutting roller, wherein the wire is cut into individual nose wires. The individual nose wires from the cutting roller are then engaged by a set of delivery rollers to deposit the individual nose wires onto a running carrier web. The delivery rollers are independently driven relative to the feed rollers and cutting roller such that the nose wires from the cutting roller are initially accelerated and transported away from the cutting roller at a second speed that is greater than the first speed and then decelerated and moved onto the carrier web at a third speed that is less than the first speed.

Unwinding systems and methods are provided for unwinding a fiber from a bobbin. The unwinding system can include an axle defining a first axis extending an axial direction, a bobbin rotatably mounted around the axle, a pulley positioned to receive the fiber from the bobbin, wherein the pulley is rotatable around a second axis, and a sensor positioned between the bobbin and the pulley. The bobbin is moveable along the axial direction, and wherein the fiber extends tangentially from a surface of the bobbin.

A large diameter lay-flat hose spool apparatus has a mobile platform with a chassis and wheels. Side supports extend up from the chassis. An axle bears on the side supports, spanning a gap therebetween. Plural spools are rotatably mounted on the axle. Each spool has at least one rim and a length of lay-flat hose wound thereon. A driver rotates the individual spools about the axle independently of the other spools. The driver has a first actuator that moves a drive wheel into and out of contact with a rim of one of the spools. The driver has a second actuator that moves the drive wheel from one of the spool rims to another of the spool rims. A motor rotates the drive wheel. A controller system operated the motor, the first actuator and the second actuator.

A cable drum transportation and handling apparatus for mounting, transporting and handling large cable drums includes a supporting structure, which supporting structure may be mounted on a truck or trailer. The apparatus includes stabilizers mounted to the supporting structure, a hydraulics control system and an operator station, a gravity drive having a drive wheel tire for turning the drum to spool cable in or out, and a hydraulic drive system for the gravity drive. An adjustable mechanism ensures firm connection between the tire and a cable drum, when a drum is mounted on the apparatus. A lever arm or bolt pattern puts more or less tension on the gravity drive, for engagement, by moving the drive up and down. Opposing hydraulically-operated lift arms pivotally mounted on an upper part of the supporting structure may be pivoted outwardly and rearwardly. The lift arms laterally close to grasp the drum. Mounts on the end of each arm have a center pin that inserts into the center axis of the drum and a pair of engagement pins that are inserted between the spokes of the drum to assist in holding the drum in place. The apparatus may also include a mounting bracket for a banding cart to hold banding for the cabling.

A device that pulls out an optical fiber includes: a bobbin support that supports a bobbin rotatably about a rotation axis; a first pulling out unit that holds a first end of the optical fiber, pulls out a first portion of the optical fiber wound around the bobbin from a side of the first end in a state where the bobbin rotates in a predetermined direction, and returns a part of the first portion to the bobbin in a state where the bobbin rotates in a direction opposite to the predetermined direction; and a second pulling out unit that holds a second end of the optical fiber after the first pulling out unit pulls out the first portion from the side of the first end, and pulls out a second portion of the optical fiber wound around the bobbin from a side of the second end.
