A method for electrification of a field chopper comprising the steps of: providing a cable drum and a winding drive on the field chopper, the cable drum and winding drive allowing at least one of the winding and unwinding of an energy supply line about the cable drum; providing a cable arm on the field chopper, the cable arm configured to adjust in at least one of an orientation and extension length to provide guided winding or unwinding of the energy supply line along a field surface; providing a pivotable ejection chute on the field chopper, the ejection chute extending beyond the cable arm and configured to transfer a chopped harvested material onto a transport vehicle driving alongside the field chopper; unwinding the energy supply line while along a first processing strip from the cable drum using the winding drive and cable arm; and winding the energy supply while along a second processing strip about the cable drum using the winding drive and the cable.

The invention relates to a method for detecting a traverse winding defect when winding a link (L) on a spool (1) rotatably driven about a longitudinal axis (X), the link (L) being alternately translationally guided relative to the spool (1) by a guide pulley (2) along said longitudinal axis (X) between two reversal positions, comprising: measuring the position of the guide pulley (2) relative to the spool (1) along the longitudinal axis (X) over time, measuring the position (P2) of a regulation device for regulating the advance speed of the link on the guide pulley over time, from said measurements, determining a deviation between the position (P3) of the regulation device and a reference position (P3r) at each reversal position (Pi1,Pi2), and from said deviation, detecting the formation of a hollow or bump in the winding.

The present disclosure is generally directed towards calculating a remaining length of a cable on a cable reel. Generally, a first distance between a top edge of a first flange of the cable reel and a top portion of the cable remaining on the cable reel is received at a processor. A winding characterization indicating a configuration of the cable wound on the cable reel is also received at the processor. Dimensions of the cable reel are also received at the processor and include: a diameter of the first flange, a cable reel traverse distance, and a diameter of a drum of the cable reel. The cable reel traverse distance indicates a distance between the first and second flanges of the cable reel. The remaining length of the cable on the cable reel is calculated based on the first distance, the winding characterization, and the dimensions of the cable reel.

A method for implementing a correct winding of a wire on a spool. The method is characterized in that it comprises a step for calculating the angular speed of a motor displacing a wire dispensing device according to the wire winding pitch and according to the pulling error, detected in relation to a given pre-set set-point and to a tolerance value, in order to determine the presence of a possible “valley error”, or of a possible “peak error”. Furthermore, if during the spool winding a “valley error” or a “peak error” is detected, the control device decides whether to slow down or to increase the speed of the wire dispensing device with the aim of filling the valley or of skipping the peak.

System for controlling the loading or unloading a cable [2] or the like onto a drum [3], wherein the drum [3] has a known first rotation axis loading or unloading the cable, the system also comprises an imaging means [1] aimed at the cable [2] from a position at a distance from the drum rotation axis, the imaging means [1] being adapted to measure the direction of the cable [2] relative to the rotational axis of the drum. The imaging means can be constituted by a video camera.

The present invention relates to a string adjusting device. According to the present invention, there is provided a string adjusting device, including: a base unit including a base plate, a cylindrical lower housing provided on the base plate, and stop protrusions formed to protrude from an outer surface of the lower housing; and a rotation unit including a bobbin rotatably installed inside the housing and configured such that a string is wound therearound, a rotation head connected to one end portion of the bobbin, and an engagement member formed and provided inside the rotation head to be elastically deformable and configured to be caught on the stop protrusions.

A refueling system, comprising a drum rotatable to wind and unwind a hose, a carriage guiding the hose and lineally displaceable along a shaft parallel to the longitudinal direction of the drum so as to follow the movement of the hose along the drum. The shaft allows the displacement of the carriage along its length. A motor is coupled to the carriage and displaces the carriage along the shaft. A first position sensor communicates with the carriage to obtain its position. A second position sensor communicates with the drum to obtain the position of the hose. A control system is coupled to the first and the second sensor, to compare their obtained positions and to operate the motor.

A cable drum for supplying energy to an electrically operated utility vehicle includes an axially extending winding body, a winding drive for rotatably driving the winding body for reeling-up or unreeling an electric line, a spacing means for segmenting a winding layer reeled-up onto the winding body, and an air conveying means for generating cooling air through a passage region. The cooling air flows outward of the interior of the winding body. The passage region is kept clear between adjacent segments of the winding layer.
