What is a gypsy head on a ship?
I referred to Gypsy heads or the other term as a horizontal capstan mounted either on the tow winch and/or the anchor windlass. A moving part.
What is a Warping end?
A single yarn that runs lengthwise in a woven fabric.
What is Warping drum?
The warping drum intended for installation on ocean-going ships serves for veering in a capron rope. It also can be used as a winch for hoisting and lowering a cargo up to 500 kg in mass by means of a steel rope to a height of 20 m. Type of the warping drum: horizontally-mounted, motor-driven, two-speed, reversing.
Why do they call it a windlass?
windlass (n.)
device for raising weights by winding a rope round a cylinder, c. 1400, alteration of wyndase (late 13c.), from Anglo-French windas, and directly from a Scandinavian source such as Old Norse vindass, from vinda “to wind” (see wind (v. 1)) + ass “pole, beam” (cognate with Gothic ans “beam, pillar”).
What is the windlass gypsy also called?
The wheels on either a vertical or horizontal windlass provide for either chain or line to be engaged. The wheel for line is termed a warping head, while the chain handling wheel is variously referred to as the gypsy (in the UK) or wildcat (in North America).
Which is stronger warp or weft?
Warps yarns are stronger compared to weft yarns. During the weaving warps are held under high tension, moves up and down for shed formation. Warp yarns are finer than weft yarns.
What is the difference between a warp and a weft?
Warp and weft are the two basic components used in weaving to turn thread or yarn into fabric. The lengthwise or longitudinal warp yarns are held stationary in tension on a frame or loom while the transverse weft (sometimes woof) is drawn through and inserted over and under the warp.
How does warp break?
Breaks due to impurities: Fly which is sized and flattened produces warp breaks because of its inability to pass through reed dent, heald eye and drop wires. This type of break occurs in the shedding region and the back zone.
What is mooring winch?
Mooring winch is a mechanical device used for securing a ship to the berth. An equipment with various barrels used for pulling ropes or cables, mooring winches play an important role in berthing the ship ashore.
What does the term Gypsyhead refer to on a winch?
Definition of gypsyhead
: a small auxiliary drum on the end of a winch or windlass.
What is a ship capstan?
capstan, mechanical device used chiefly on board ships or in shipyards for moving heavy weights by means of ropes, cables, or chains. Capstans also have been used in railroad yards for spotting (positioning) freight cars.
Why is an anchor called a winless?
An important point to note about the naming of the word “windlass” is that it generally refers to only horizontal motion of the weight. The “capstan” is the equipment used for vertical motion.
What is a gypsy winch?
Definition of gypsy winch
1 : a small winch that may be operated by a crank. 2 : a winch with a gypsyhead.
Why does an anchor have a chain?
-Chain allows the anchor to set faster and more reliably by creating a downward pull on the anchor handle (also referred to as the shank). -Helps the rode to lie horizontally once set, rather than be pulled upward and loosen the anchor.
What is the difference between a winch and a windlass?
The difference between a winch and a windlass is that the line wraps around and around the cylindrical portion of a winch; whereas the line goes into the forward end of the windlass, passes around the gypsy (cylinder/drum/pulley) and exits out the back (or bottom) of the windlass housing.
What is a chain stopper?
Definition of chain stopper
: a device (as a hook) that secures the anchor chain (as when the anchor is raised) thus taking the strain from the windlass.
What are the types of windlasses?
There are horizontal and vertical anchor windlass, the general ship use horizontal anchor windlass. And vertical anchor windlass also called anchor capstan and its power below deck, to save the deck area , naval ships widely use vertical anchor windlass.
What are the 3 basic weaves?
The basic weaves include plain (or tabby), twills, and satins.
Which weave is the strongest?
Interlaced weft (horizontal) and warp (vertical) yarns cross each other in a pattern of one over and one under. Because of the high number of (perpendicular) crossings, each intersecting thread gives maximum support to the adjacent threads. Plain weave is stronger and firmer than any other ordinary weave.
How do you tell warp from weft without selvage?
Yarn appearance: Warp yarns are comparably finer than weft yarns and comparably higher twisted yarn. Stripe/check patterns: If fabric got coloured stripes then stripe direction shows warp (mostly). In checks, if you find one colour with odd numbers of threads, it is warp.
