A container may be provided. The container may comprise a first surface and a second surface concentric with the first surface. The first surface and the second surface may define a volume. The volume may house a concentric length of multiple parallel conductors. The multiple parallel conductors may pass through a restricting mechanism to restrict the multiple parallel conductors to pass at the same rate and at the same length.

The present disclosure discloses a thread tension adjusting device comprising a body, a tension rod, an elastic element and an adjusting knob. A thread passing eye for inputting a thread is arranged below the body. A tension wheel and a thread passing wheel are rotatably arranged on the body. An adjusting knob is used for adjusting a rotational speed of the tension wheel. The elastic element has one end connected to the body and another end connected to the tension rod. The thread tension adjusting device may ensure stability of tensioning and transmitting of the thread by cooperation between the tension rod and the tension wheel, and improve precision for thread tension adjusting by the adjusting knob. In addition, the thread tension adjusting device may monitor thread breakage by the tension detector, and ensure operating stability and safety of the thread tension adjusting device.

Package cradle has at least one movable, partially rotatable frame arm and designed so an empty tube with length of at least 315 mm is insertable, that the package drive roller has length of at least 286 mm, that yarn traversing device has traversing stroke of at least 11 inches, and that opening in cover corresponds with the yarn path arising due to the traversing stroke.

A pushing tool for propelling cable into a duct. The pushing tool includes a drive wheel that is coupled with a base and a rotatable handle. A first cable guide and a second cable guide are configured to hold the cable. A duct guide is configured to hold the duct. Furthermore, a tension wheel is configured to interact with the drive wheel such that an orifice is formed between the tension wheel and the drive wheel, the orifice being configured to receive the cable. Upon rotation of the rotatable handle, the drive wheel interacts with the tension wheel to propel the cable into the duct.

A method for obtaining a diameter is provided. The method is to be applied to a multi-roller module system and includes: designating a target linear velocity associated with a wire moving in the multi-roller module system, and a value of a presumed diameter parameter associated with a diameter of a main roller; calculating an initial rotational speed of the main roller; measuring a current rotational speed of the fixed-diameter rotating component; calculating an actual linear velocity of the wire; and determining that the value of the presumed diameter parameter equals an actual diameter of the main roller when it is determined that the ratio of the target linear velocity to the actual linear velocity is equal to one.
