A vibrating shuttle is a bobbin driver design used in home lockstitch sewing machines during the second half of the 19th century and the first half of the 20th century. It supplanted earlier transverse shuttle designs, but was itself supplanted by rotating shuttle designs.
The hook mechanism carries the upper thread entirely around the bobbin case so that it has made one wrap of the bobbin thread. Then the take-up arm pulls the excess upper thread (from the bobbin area) back to the top, forming the lockstitch. Then the feed dogs pull the material along one stitch length, and the cycle repeats.
The bobbin winder is mounted high on the pedestal, where a small rubber tire occupying its pulley makes contact with the motor belt. The new mounting position solves the bobbin winder belt problem discussed later. Dedicated motor mounting lugs, cast into the rear of the pillar, standardize the position of the motor bracket.
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 (right) and bobbin case for a shuttle hook sewing machine, introduced by Singer for the "Improved Family" model in 1895 The lockstitch sewing machine, invented and developed in the 18th and 19th centuries, [ 10 ] [ 11 ] forms a stitch with two threads: one passed through a needle and another from a bobbin.
Bobbin lace ground is the regular small mesh filling the open spaces of continuous bobbin lace.Other names for bobbin lace ground are net or réseau (French for network). The precise course of the threads and the resultant shape of the ground are an important diagnostic feature in lace identification, as different lace styles use different groun
The design became obsolete once the other bobbin driver designs were developed. [3] Shuttle from a transverse shuttle bobbin driver: Sometimes incorrectly called an "oscillating shuttle". Somewhat confusingly, the term "Transverse Shuttle" is usually used only to refer to a side-to-side motion of the bobbin.
Bobbin lace is a lace textile made by braiding and twisting lengths of thread, which are wound on bobbins to manage them. As the work progresses, the weaving is held in place with pins set in a lace pillow , the placement of the pins usually determined by a pattern or pricking pinned on the pillow.
