CHAPTER XVII--OCCUPATIONAL SAFETY AND HEALTH ADMINISTRATION, DEPARTMENT
OF LABOR
PART 1910_OCCUPATIONAL SAFETY AND HEALTH STANDARDS--Table of Contents
Subpart R_Special Industries
Sec. 1910.262 Textiles.
(a) Application requirements--(1) Application. The requirements of
this subpart for textile safety apply to the design, installation,
processes, operation, and maintenance of textile machinery, equipment,
and other plant facilities in all plants engaged in the manufacture and
processing of textiles, except those processes used exclusively in the
manufacture of synthetic fibers.
(2) Standards incorporated by reference. Standards covering issues
of occupational safety and health which are of general application
without regard to any specific industry are incorporated by reference in
paragraphs of this section and made applicable to textiles. All such
standards shall be construed according to the rules of construction set
out in Sec. 1910.5.
(b) Definitions applicable to this section--(1) Belt shifter. A belt
shifter is a device for mechanically shifting a belt from one pulley to
another.
(2) Belt shifter lock. A belt shifter lock is a device for
positively locking the belt shifter in position while the machine is
stopped and the belt is idling on the loose pulleys.
(3) Calender. A calender in essence consists of a set of heavy
rollers mounted on vertical side frames and arranged to pass cloth
between them. Calenders may have two to ten rollers, or bowls, some of
which can be heated.
(4) Embossing calender. An embossing calender is a calender with two
or more rolls, one of which is engraved for producing figured effects of
various kinds on a fabric.
(5) Cans (drying). Drying cans are 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.
(6) Carbonizing. Carbonizing means 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.
(7) Card. A card machine consists 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.
(8) Card clothing. Card clothing is 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.
(9) Comber. A comber is a machine for combing fibers of cotton,
wool, etc. The essential parts are a device for feeding
[[Page 708]]
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.
(10) Combing machinery. Combing machinery is a general
classification, including combers, sliver lap machines, ribbon lap
machines, and gill boxes, but excluding cards.
(11) Cutter (rotary staple). A rotary staple cutter is a machine
consisting of one or more rotary blades used for the purpose of cutting
textile fibers into staple lengths.
(12) Exposed to contact. Exposed to contact shall mean that 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.
(13) Garnett machine. A Garnett machine means 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.
(14) Gill box. A gill box is 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.
(15) Interlock. An interlock is 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.
(16) Jig (dye). A dye jig is 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.
(17) Kier. A kier is a large metal vat, usually a pressure type, in
which fabrics may be boiled out, bleached, etc.
(18) Lapper (ribbon). A ribbon lapper is 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.
(19) Lapper (sliver). A sliver lapper is 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.
(20) Loom. A loom is 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.
(21) Mangle (starch). A starch mangle is a mangle that is used
specifically 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.
(22) Mangle (water). A water mangle is 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.
(23) Mule. A mule is 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.
(24) Nip. Nip shall mean the point of contact between two in-running
rolls.
(25) Openers and pickers. Openers and pickers means 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,
[[Page 709]]
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.
(26) Paddler. A paddler consists 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.
(27) Point of operation. Point of operation shall mean that part of
the machine where the work of cutting, shearing, squeezing, drawing, or
manipulating the stock in any other way is done.
(28) Printing machine (roller type). A roller printing machine is 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.
(29) Ranges (bleaching continuous). Continuous bleaching ranges are
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.
(30) Range (mercerizing). A mercerizing range consists generally of
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.
(31) Sanforizing machine. A sanforizing machine is 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.
(32) Shearing machine. A shearing machine is 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.
(33) Singeing machine. A singeing machine is a machine used
particularly with cotton; it comprises 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.
(34) Slasher. A slasher is 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.
(35) Solvent (industrial organic). Industrial organic solvent means
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.
(36) Tenter frame. A tenter frame is 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
[[Page 710]]
they move forward so that the cloth is brought to the desired width.
(37) Warper. A warper is any machine for preparing and arranging the
yarns intended for the warp of a fabric, specifically, a beam warper.
(c) General safety requirements--(1) Means of stopping machines.
