The invention relates to a system of spinning yarn that comprises a filament feed system configured to vary the tension applied to at least two continuous filaments before the filaments are introduced to a roving and twisted to form a yarn. The invention allows the filaments to be introduced to the roving when under tension, under no tension, or when under slack at set distances from the roving centre line by a specialized two filament guide.

Computer program product, controller, winding machine and method for winding a winding material from a supply device onto a winding body of a winding machine, wherein the winding material is provided from a supply roller and wound onto the winding body via at least one deflection roller, where an actual winding tension of the winding material is set to a setpoint winding tension depending on a position-dependent compensation signal, stored in a storage unit, to compensate for a changeable free length, resulting from a non-circular cross section of the winding material, of the winding material between the deflection roller and the winding body, whereby due to the fact that the actual winding tension is set to the setpoint winding tension via the position-dependent compensation signal, which is already stored in the storage unit prior to the winding, the computational load for the setting can be reduced.

A method for laying multiple conductors in a container may be provided. The method may comprise receiving the multiple conductors at a monitoring station; receiving the multiple conductors at a drive; and receiving the multiple conductors at the container.

A tie down apparatus wherein a center leg of each of a pair of load springs is mounted in the space between a pair of drum pins, which space receives and holds a tied down strap. Each load spring is fixedly attached to a respective one of first and second ratchet wheels and a circular plate is positioned within each ratchet wheel and configured to rotate through a selected arc with respect to each ratchet wheel to limit the pre-load applied to the load springs.

A yarn winding assembly installed on a support includes a motorized spool and an oblique spacer pin, between which a yarn is wound. The spacer pin is supported rotatably by a rotating supporting component so that it is entrained in two directions by the yarn wound between the spool and the spacer pin. The rotation of the spacer pin is delimited by an element of arrest at least in a direction of unwinding the yarn.
