Belt shifter
A device for mechanically shifting a
				belt from one pulley to another.
Belt shifter lock.
A device for positively locking
				the belt shifter in position while the machine is stopped and the belt is
				idling on the loose pulleys.
Calendar.
A machine consisting of a set of heavy
				rollers mounted on vertical side frames and arranged to pass cloth between
				them. Calendars may have two to ten rollers, or bowls, some of which can be
				heated.
Cans (drying).
Hollow cylindrical drums mounted in
				a frame so they can rotate. They are heated with steam and are used to dry
				fabrics or yarn as it passes around the perimeter of the can.
Carbonizing.
The removing of vegetable matter such
				as burns, straws, etc., from wool by treatment with acid, followed by heat. The
				undesired matter is reduced to a carbon-like form which may be removed by
				dusting or shaking.
Card clothing.
The material with which many of the
				surfaces of a card are covered; e.g., the cylinder, doffer, etc. It consists of
				a thick foundation material, usually made of textile fabrics, through which are
				pressed many fine, closely spaced, specially bent wires.
Card machine.
A machine consisting of cylinders of
				various sizes and in certain cases flats covered with card clothing and set in
				relation to each other so that fibers in staple form may be separated into
				individual relationship. The speed of the cylinders and their direction of
				rotation varies. The finished product is delivered as a sliver. Cards of
				different types are: The revolving flat card, the roller-and-clearer card,
				etc.
Comber.
A machine for combing fibers of cotton,
				wool, etc. The essential parts are a device for feeding forward a fringe of
				fibers at regular intervals and an arrangement of combs or pins which, at the
				right time, pass through the fringe. All tangled fibers, short fibers, and neps
				are removed and the long fibers are laid parallel.
Combing machinery.
A general classification,
				including combers, sliver lap machines, ribbon lap machines, and gill boxes,
				but excluding cards.
Continuous bleaching ranges.
Ranges of several
				types and may be made for cloth in rope or open-width form. The goods, after
				wetting out, pass through a squeeze roll into a saturator containing a solution
				of caustic soda and then to an enclosed J-box. A V-shaped arrangement is
				attached to the front part of the J-box for uniform and rapid saturation of the
				cloth with steam before it is packed down in the J-box. The cloth, in a single
				strand rope form, passes over a guide roll down the first arm of the "V" and up
				the second. Steam is injected into the "V" at the upper end of the second arm
				so that the cloth is rapidly saturated with steam at this point. The J-box
				capacity is such that cloth will remain hot for a sufficient time to complete
				the scouring action. It then passes a series of washers with a squeeze roll in
				between. The cloth then passes through a second set of saturator, J-box, and
				washer, where it is treated with the peroxide solution. By slight modification
				of the form of the unit, the same process can be applied to open-width
				cloth.
Cutter (rotary staple).
A machine consisting of
				one or more rotary blades used for the purpose of cutting textile fibers into
				staple lengths.
Embossing calender.
A calender with two or more
				rolls, one of which is engraved for producing figured effects of various kinds
				on a fabric.
Exposed to contact.
The location of an object,
				material, nip point, or point of operation is such that a person is liable to
				come in contact with it in his normal course of employment.
Garnett machine.
Any of a number of types of
				machines for opening hard twisted waste of wool, cotton, silk, etc.
				Essentially, such machines consist of a lickerin; one or more cylinders, each
				having a complement worker and stripper rolls; and a fancy roll and doffer. The
				action of such machines is somewhat like that of a wool card, but it is much
				more severe in that the various rolls are covered with garnett wire instead of
				card clothing.
Gill box.
A machine used in the worsted system of
				manufacturing yarns. Its function is to arrange the fibers in parallel order.
				Essentially, it consists of a pair of feed rolls and a series of followers
				where the followers move at a faster surface speed and perform a combing
				action.
Industrial organic solvent.
Any organic volatile
				liquid or compound, or any combination of these substances which are used to
				dissolve or suspend a nonvolatile or slightly volatile substance for industrial
				utilization. It shall also apply to such substances when used as detergents or
				cleansing agents. It shall not apply to petroleum products when such products
				are used as fuel.
Interlock.
A device that operates to prevent the
				operation of machine while the cover or door of the machine is open or
				unlocked, and which will also hold the cover or door closed and locked while
				the machine is in motion.
Jig (dye).
A machine for dyeing piece goods. The
				cloth, at full width, passes from a roller through the dye liquor in an open
				vat and is then wound on another roller. The operation is repeated until the
				desired shade is obtained.
Kier.
A large metal vat, usually a pressure type,
				in which fabrics may be boiled out, bleached, etc.
Lapper (ribbon).
A machine used to prepare laps
				for feeding a cotton comb; its purpose is to provide a uniform lap in which the
				fibers have been straightened as much as possible.
Lapper (sliver).
A machine in which a number of
				parallel card slivers are drafted slightly, laid side by side in a compact
				sheet, and wound into a cylindrical package.
Loom.
A machine for effecting the interlacing of
				two series of yarns crossing one another at right angles. The warp yarns are
				wound on a warp beam and pass through heddles and reed. The filling is shot
				across in a shuttle and settled in place by reed and lay, and the fabric is
				wound on a cloth beam.
Mule.
A type of spinning frame having a head stock
				and a carriage as its two main sections. The head stock is stationary. The
				carriage is movable and it carries the spindles which draft and spin the roving
				into the yarn. The carriage extends over the whole width of the machine and
				moves slowly toward and away from the head stock during the spinning
				operation.
Nip.
The point of contact between two in-running
				rolls.
Openers and pickers.
A general classification
				which includes breaker pickers, intermediate pickers, finisher pickers, single
				process pickers, multiple process pickers, willow machines, card and picker
				waste cleaners, thread extractors, shredding machines, roving waste openers,
				shoddy pickers, bale breakers, feeders, vertical openers, lattice cleaners,
				horizontal cleaners, and any similar machinery equipped with either cylinders,
				screen section, calender section, rolls, or beaters used for the preparation of
				stock for further processing.
Paddler.
Equipment consisting of a trough for a
				solution and two or more squeeze rolls between which cloth passes after being
				passed through a mordant or dye bath.
Point of operation.
That part of the machine where
				the work of cutting, shearing, squeezing, drawing, or manipulating the stock in
				any other way is done.
Roller printing machine.
A machine consisting of a
				large central cylinder, or pressure bowl, around the lower part of the
				perimeter of which is placed a series of engraved color rollers (each having a
				color trough), a furnisher roller, doctor blades, etc. The machine is used for
				printing fabrics.
Mercerizing range.
A 3-bowl mangle, a tenter
				frame, and a number of boxes for washing and scouring. The whole setup is in a
				straight line and all parts operate continuously. The combination is used to
				saturate the cloth with sodium hydroxide, stretch it while saturated, and
				washing out most of the caustic before releasing tension.
Sanforizing machine.
A machine consisting of a
				large steam-heated cylinder, an endless, thick, woolen felt blanket which is in
				close contact with the cylinder for most of its perimeter, and an electrically
				heated shoe which presses the cloth against the blanket while the latter is in
				a stretched condition as it curves around feed-in roll.
Shearing machine.
A machine used in shearing
				cloth. Cutting action is provided by a number of steel blades spirally mounted
				on a roller. The roller rotates in close contact with a fixed ledger blade.
				There may be from one to six such rollers on a machine.
Singeing machine.
A machine used particularly with
				cotton, comprised of a heated roller, plate, or an open gas flame. The material
				is rapidly passed over the roller or the plate or through the open gas flame to
				remove fuzz or hairiness on yarn or cloth by burning.
Slasher.
A machine used for applying a size
				mixture to warp yarns. Essentially, it consists of a stand for holding section
				beams, a size box, one or more cylindrical dryers or an enclosed hot air dryer,
				and a beaming end for finding the yarn on the loom beams.

				for starching cotton goods. It commonly consists of two large rolls and a
				shallow open vat with several immersion rolls. The vat contains the starch
				solution.
Tenter frame.
A machine for drying cloth under
				tension. It essentially consists of a pair of endless traveling chains fitted
				with clips of fine pins and carried on tracks. The cloth is firmly held at the
				selvages by the two chains which diverge as they move forward so that the cloth
				is brought to the desired width.
Warper.
Any machine for preparing and arranging
				the yarns intended for the warp of a fabric, specifically, a beam
				warper.
Water mangle.
A calender having two or more rolls
				used for squeezing water from fabrics before drying. Water mangles also may be
				used in other ways during the finishing of various fabrics.
