A Brunnian link is a link formed from a closed loop doubled over itself to capture another closed loop to form a chain. The example kit provides for the successful creation of unique wearable articles using Brunnian link assembly techniques and includes several pin bars that are supported in a desired special orientation by at least one base. The desired special orientation is dependent on the desired linked configuration of the completed article. The pins may be assembled in various combination and orientations to provide endless variation of completed link orientations.

A knot stretcher for use in tightening splice knots that connect twine balls on an agricultural baler. The knot stretcher includes a pair of pulling bars connected at pulling bar pivot at one end of each of the pulling bars, and a pair of levers, where one of the pair of levers is attached in a middle section of its respective pulling bar. Each lever has a handle portion at one end and an arm portion extending from an elbow formed in the lever. Each lever attaches to its respective pulling bar with a fixed pivot located near the elbow and distal ends of the arm portions of the two levers are attached at a moving pivot. The knot stretcher has clamping jaws positioned on the pulling bars to securely clamp a respective one of the twine tails of the splice knot that is to be tightened.

A device of executing vacuum processing has a chamber capable of keeping the chamber as a whole in a depressurized state; a feeding roller so disposed as to hang a reinforcement fiber down in the chamber; a processor so disposed in the chamber as to pass the reinforcement fiber hung down in the chamber through the processor; a capture device so disposed as to capture and keep a leading end of the reinforcement fiber passing the processor and vertically falling down in place; a winding bobbin configured to wind the reinforcement fiber processed by the processor; and a resilient cord withdrawn in synchronism with the winding bobbin from a first position where the resilient cord surrounds the leading end kept in place by the capture device to a second position where the resilient cord gets in contact with and leads the reinforcement fiber to the winding bobbin.

The present disclosure discloses a process for knotting roving packages, comprising steps of: arranging a plurality of roving packages in a single layer or multiple layers; classifying all roving packages into at least one group of roving packages; selecting, from each group of roving packages, two roving packages as a starting roving package and an ending roving package; successively connecting all roving packages in each group of roving packages from the starting roving package to the ending roving package; and, connecting an inner fiber of a roving package other than the starting roving package and the ending roving package in each group of roving packages to an outer fiber of a previous roving package and connecting an outer fiber of this roving package to an inner fiber of a next roving package, or connecting an outer fiber of a roving package other than the starting roving package and the ending roving package in each group of roving packages to an inner fiber of a previous roving package and connecting an inner fiber of this roving package to an outer fiber of a next roving package. By the process of the present disclosure, the labor cost for manually knotting and moving roving packages per unit can be saved, and creels for holding roving packages per unit can also be reduced. This process is a technical improvement of the packaging technology.
