The unwind stage holds the roll stably and allows it to spin; it is either braked or driven to maintain accurate tension in the material. Some machines have a driven unwind which reduces the effect of inertia when starting to unwind heavy rolls or when the material is very tension-sensitive. The slitting section has four main options:
To make one stitch, the machine lowers the threaded needle through the cloth into the bobbin area, where a rotating hook (or other hooking mechanism) catches the upper thread at the point just after it goes through the needle. The hook mechanism carries the upper thread entirely around the bobbin case so that it has made one wrap of the bobbin ...
Toilet-tissue winders are able to change over at running speed, while paper and board winders need to stop the winding process in order to cut the sheet and glue the paper on to a new wind-up core. Top-line winders introduce the paper core through a maintenance pit downstairs, with web interruption time as low as 15 seconds.
The machine stops. The thread guides are hinged up. The completed bobbin coils (yarn packages) are removed from the spindles. The new bobbin tube is placed on the spindle trapping the thread between it and the cup in the wharf of the spindle, the thread guides are lowered and the machine restarted. Now all the processes are done automatically.
Cro-tatting combines needle tatting with crochet. The cro-tatting tool is a tatting needle with a crochet hook at the end. One can also cro-tat with a bullion crochet hook or a very straight crochet hook. In the 19th century, "crochet tatting" patterns were published which simply called for a crochet hook.
Sewing awls are used to make lock stitches. The needle, with the thread in the eye is pushed through the material. The thread is then pulled through the eye to extend it. As the needle is pushed through the material, the extra thread from the first stitch is then threaded through the loops of successive stitches creating a lock stitch.
The rotary hook or rotating hook is a bobbin driver design used in lockstitch sewing machines since the 19th century. It triumphed over competing designs because it can run at higher speeds with less vibration. Rotary hooks and oscillating shuttles are the two most common bobbin drivers in use today.
Bobbin tape lace. Bobbin tape lace is bobbin lace where the design is formed of one or more tapes curved so they make an attractive pattern. [1] The tapes are made at the same time as the rest of the lace, and are joined to each other, or themselves, using a crochet hook. The tapes are made curved, and by hand, using bobbin lace techniques.
