A system includes a vehicle cover, a mechanical tensioning device, a memory device, storing instructions, and one or more processors configured to execute instructions to perform the steps of a method to secure a vehicle. The mechanical tensioning device may include attachment means to attach the device to a wheel of the vehicle and means to attach a security cable of the vehicle cover integrated into a bottom edge of the vehicle cover to the mechanical tensioning device. The mechanical tensioning device may include a rotational reel connected to either a tensioning motor or a tensioning crank and optionally including either a mechanical bi-stable device or one or more sensors configured to monitor the tension of the security cable when engaged to the mechanical tensioning device. The processor may monitor for a change in tension and execute one or more security measures in response.

A cable tension control device includes a pair of first active rollers clamping a cable therebetween, a first driver driving the first active rollers, a pair of second active rollers clamping the cable therebetween at an upstream position from the first active rollers, a second driver driving the second active rollers, a floating roller arranged between the first active rollers and the second active rollers and exerting a pushing force on the cable, and an actuator driving the floating roller to move vertically to adjust the pushing force exerted on the cable. A tension force applied on the cable is controlled to be equal to a predetermined tension force by controlling the pushing force and by controlling a speed difference between a first speed at which the first active rollers convey the cable forward and a second speed at which the second active rollers convey the cable forward.

A control device of a transport device includes a control unit configured to control a roll motor for rotating a first rotary shaft on which a medium is held and a transport motor for rotating a first driving roller, a tension detection unit configured to derive, for each tension detection cycle, a detected tension value of a tension applied to a tension adjustment portion of the medium, and a tension F/B unit configured to calculate a tension F/B correction amount by feedback control based on a deviation between a target tension and the detected tension value. The control unit is configured to calculate a driving force by the roll motor based on the tension F/B correction amount, and control the roll motor based on the driving force.

A cable tensioning capstan assembly comprises a capstan drum and at least a first traction flange. The capstan drum may be configured to support a cable (e.g., a cable is configured to wrap around the capstan drum), and the capstan drum may be configured to rotate about an output axis. The first traction flange may be disposed adjacent the first axial end of the capstan drum and configured to rotate about the output axis. In various embodiments, the first traction flange is independently rotatable relative to the capstan drum. A clutch assembly between an input shaft and the first traction flange may facilitate the independent rotatability of the first traction flange.

A method for winding a synthetic yarn coming from an extruder including the steps of connecting at least one yarn exiting from an extruder with at least one corresponding bobbin rotatable around a longitudinal axis thereof, on which the yarn is wound; rotating the bobbin by imparting a specific speed and/or torque to the bobbin; measuring a value of the tension acting on the yarn upstream of the bobbin; adjusting the speed and/or the torque to maintain the measured tension value substantially equal to a constant reference value of the tension.

A method for feeding a thread at a preset drawing to a textile machine includes a first feeder which sends the thread to the textile machine and a second feeder arranged spaced from the first feeder and which sends such thread to the latter, each feeder having a rotary member on which there is partly wound the thread before the feeding thereof and a speed sensor adapted to detect the rotational speed of such rotary member and a tension sensor to detect the tension of the thread exiting from each feeder. Controlling drawing the thread sent to the textile machine by controlling and adjusting the ratio between the rotational speed of the rotary member of the first feeder and the rotational speed of the rotary member of the second feeder.

The invention relates to a bobbin carrier 7 for receiving a bobbin 2 which is set up for unwinding a strand material I, wherein the bobbin carrier 7 is provided for use in a braiding, winding or spiralling machine and is set up to rotate relative to the machine during operation of the latter. The bobbin carrier 7 has a tensile-force measuring device 3 for measuring the tensile force of the strand material I unwound from the bobbin 2 and has a first data transfer device 4 for transferring data. According to the invention, the first data transfer device 4 is set up to transfer measured tensile force values to a second data transfer device 5 arranged outside the bobbin carrier. As a result, too low or too high tensile forces in the strand material I can be detected early at the individual bobbin carriers 7. The tensile force can be kept largely constant by the transfer of setpoint tensile force values from the second data transfer device 5 to the first data transfer device 4 and by a suitable control or regulation device 8 at the bobbin carrier 7.
