Bobbin

From Wikipedia, the free encyclopedia
Spool or cylinder around which thread, line or wire is coiled.
For other uses, seeBobbin (disambiguation).
Vintage wooden bobbins, cylindrical, empty of wound fiber, dimensions 16 in. high by 9 in. in diameter.
Vintage wooden bobbin, unflanged, wound with yarn and attached to a "shuttle" that fits it for use in a floor loom.

Abobbin orspool is a spindle or cylinder, with or withoutflanges, on whichyarn,thread,wire,tape orfilm is wound.[1] Bobbins are typically found in industrialtextile machinery,[2] as well as insewing machines,fishing reels,tape measures,film rolls,cassette tapes, withinelectronic andelectrical equipment, and for various other applications.[not verified in body]

Bobbins are used inspinning,weaving,knitting,sewing, andlacemaking.[3][4] In these practices, bobbins were invented to "manage the piles of thread and yarn that would be mechanically woven into cloth,"[2] which would have originally been wound through the use of human power, but which eventually became machine-driven.[citation needed] In these applications, bobbins provide storage, temporary and permanent, foryarn orthread.[citation needed] Historically, bobbins were made out of natural materials such aswood,[2] orbone.[5] While not in principle an invention of theVictorian era - bobbins in the production of textiles were in earlier use[6][7] - the machinery introduced in that era "were some of [its] greatest inventions" in that they "helped to revolutionize textile manufacturing".[2] In the machines used in such manufacturing,

The automated weaving machines would have hundreds of spindles operating simultaneously, with each spindle holding a bobbin that either released or collected the thread. Most mills had wooden bobbins made specifically for their machinery, which accounts for the many varied shapes and sizes of these spools.[2]

In more modern times, natural bobbin materials such as wood are no longer used in textile manufacturing,[2] instead having been replaced bymetal andplastic.[8][9] The traditional bobbins made, for instance, of hardwoods such as ash and birch are unsuitable for the machinery of modern manufacturing, given the higher speeds involved, and the synthetic materials that are used in weaving; as well, bobbins were relatively customised parts made for the specific machines of each mill (and so of varying designs, each uniquely shaped of wood,[2] with metal parts in places of high wear[citation needed]), thus requiring "a great deal of handwork" such that the cost of continuing to make them was unfavorable to modern textile business.[2]

Since the retirement of the machinery involved, such bobbins and related parts have become items used incraft productions, given the numbers of distinct types, and the fact that "[e]ach... has its own 'battle scars' that give it unique character".[2]

Sewing and lacemaking

[edit]

Sewing

Thelockstitch 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. Each thread stays on the same side of the material being sewn, interlacing with the other thread at each needle hole thanks to the machine's movement.[12] Tension of the bobbin thread is maintained with abobbin case, a metal enclosure with aleaf spring which keeps the thread taut. The bobbin case has to be free-floating (not attached to an axle) in order to allow the top thread to pass around the bobbin completely and hook the bobbin thread.

Bobbins vary in shape and size, depending on the style ofbobbin driver in the machine for which they are intended to be used. Long, narrow bobbins are used in early transverse shuttle andvibrating shuttle machines. These earlier movements were rendered obsolete by the invention of therotary hook and the shuttle hook, which run faster and quieter with less air resistance. These shorter, wider bobbins are familiar to modern sewers, as the rotary/shuttle hook remains in use on modern machines essentially unchanged.

Lacemaking

[edit]

Bobbin lace requires the winding of yarn onto a temporary storage spindle made of wood (or, in earlier times, bone) often turned on alathe. Many lace designs require dozens of bobbins at any one time.

Both traditional and contemporary bobbins may be decorated with designs, inscriptions, or pewter or wire inlays. Often, bobbins are 'spangled' to provide additional weight to keep the thread in tension. A hole is drilled near the base to enable glass beads and other ornaments to be attached by a loop of wire. Thesespangles provide a means of self-expression in the decoration of a tool of thecraft.

Antique and unique bobbins, sometimes spangled, are highly sought-after by antiques collectors.[13][page needed][14][15][16]

Electrical

[edit]

Inelectrical applications,transformers,inductors,solenoids, andrelay coils use bobbins as permanent containers for the wire to retain shape and rigidity, and to ease assembly of the windings into or onto themagnetic core.[17] (Suchcoils of wire carryingcurrent create theinduced currents andmagnetic fields required in these devices.)[18]

Bobbins in these applications may be made ofthermoplastic orthermosetting materials (for example,phenolics);[19] this plastic often has to have aTÜV,UL, or other regulatory agency flammability rating for safety reasons.[20][21]

Furniture

[edit]

Bobbin furniture (also known as spool furniture) is a style of table or chair with lathe-turned legs.[22][23]

Miscellaneous applications

[edit]

Bobbins are also used forfly tying and tidy storage without tangles.[24][25]
