This is the generic class for the treatment of textile fabrics
subsequent to the fabrication thereof for putting them in better
Due to the similarity of the shearing of fur in the finishing
of a fur skin to the shearing of the surface fibers or threads of
cloth, particularly that of pile fabric, and the finishing of fur
by shearing is included in this class.
SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
Due to the similarity of apparatus for the stretching of plastic
film to apparatus for the stretching of fabric, the former has been
placed in this class (26), along with the latter (see subclass References
to the current Class, below). However, process for the stretching
of plastic film is not in this class: rather it is in Class 264,
Plastic and Nonmetallic Article Shaping or Treating: Processes,
subclass 288.4 (see particularly subclass 290.2).
SECTION III - SUBCLASS REFERENCES TO THE CURRENT CLASS

ends to effect movement of the material.
This subclass is indented under subclass 7. Processes and apparatus for the removal of projecting weft
ends from the edge of fabric, or for the removal of loops connecting
nonadjacent wefts and floating along the edge of the fabric.
Note. Selvage float loops often are formed in weaving on
looms equipped with multiple shuttle boxes, one or more of which
boxes (at any stage of weaving) contain inactive filling packages
each of which is still connected by an integral length of weft yarn
to the last pick of filling laid from that package and which, upon
re-entry into active filling laying, operates to extend such length
of weft adjacent to but outside of the fabric selvage in the form
of a loop or external float thread.
subclass 170.3 for means effective to prevent the fouling of inactive
filling threads in multiple-shuttle-box looms, noting particularly
subclass 170.4 for such apparatus combined with a cutter; and subclass
302 for loom-mounted selvage trimmers.

increase a dimension thereof or to apply tension thereto to inhibit
shrinkage or to remove wrinkles, creases, or folds.

subclasses 288.4+ for the method of stretching a running length of
plastic; e.g., subclass 290.2 for the biaxial stretching thereof,

or to prevent or correct improper operation.
Note. Cloth pull to drive an element (even such a spreader
element as specified in the the roller of subclasses 97 or 99+)
in itself does not constitute operation control for these subclasses
(74+). Compare, however, with subclass 77 indented hereunder
(74+), in which cloth pull not only drives the spreader
but, further, controls and adjusts the angle of the roller and thereby
of the selvage position responsive to the selvage location.

and in which, responsive thereto, a second, inward companion, traveling
spreader is conditioned to retain that edge at a position closer
to the longitudiinal axis of the traveling web.

spreaders, which subclass may further disclose the (unclaimed) inboard-outboard
companion pair of grippers and means responsive thereto for activating
the companion inboard spreaders.
This subclass is indented under subclass 71. Spreader including a member positioned to be enveloped by
continuous tubular cloth web increments and dimensioned engagingly
to force the cloth increments outwardly in a plane transverse to
the running direction of the web.
This subclass is indented under subclass 80. Spreader in which (a) the enveloped member is heated for

the rotatable means at the spreading plane extremities for driving
the cloth increments.
Note. The driven web-feeding rollers may be at the ends of
at least one pair of opposed, enclosed spreader arms or they may
be feed roller contacting the spreader arm extremities from the
outside, with opposed web increments passing between the rollers
and the spreader arm extremities. It is possible, for indented
subclass 85 for an enclosed driven cylinder to constitute the web drive
means for this locus, with diametrically opposed peripheral points
thereof constituting the driven extremities.
This subclass is indented under subclass 84. Spreader in which the enveloped spreader member is of a
width, in at least two intersecting dimensions transverse to the
running length direction of the web, to spread the cloth along corresponding

plurality (or infinite number) of transverse spreading planes is
adequate to satisfy the requirement(s) of this subclass.
This subclass is indented under subclass 71. Structure either (a) in an arrangement, or further including
means repetitively to bunch successive increments of the running
web of cloth; or (b) spreader structure including series of cloth
edge penetrating and accompanying members and rotary disc means

classified therewith whether or not used or useful, as disclosed,
toward that purpose (e.g., even when they are idlers, etc.).

Note. The terms "edge" and "selvage" are
used interchangeably and are completely synonymous with one another.
for the shrinking of a cloth web of warp and weft
construction including advancing it through the apparatus in a direction
opposite to that which would cause spreading. Where the invention
is to apparatus selectively to perform one or the other operation, the
original will be found in that subclass (18.6) and a cross only
in the instant subclass (88).
This subclass is indented under subclass 88. Spreader constituted by a (usually paired) series of discrete
edge-retaining members which become affixed to and which thereby accompany
successive edge increments of the running length (usually, again,
both edges by each accompanying pair).

(are) spaced connected about the periphery of a rotating annular
member (usually paired) series about spaced peripheries of the member

the guide or support to said appropriate spacing or angle.
This subclass is indented under subclass 89. Spreader further including either (a) a heated member engageable
with the running length of cloth; or (b) means to apply drying or
heating gaseous fluid to the cloth.
for heating or drying means for structure which
expands cloth longitudinally of the running length; which subclass
(106) further serves for the cross-reference collection of heating or
drying means used with spreader structure of general character (i.e., other
than of instant subclass 92 or of subclass 81).
Drying and Gas or Vapor Contact With Solids, appropriate subclasses for the drying of web material,
generally, including tenter means to advance the material to or
through the dryer.See, for example, subclass(es): 4 - 41, for methods
of drying (the last being residual for the drying of webs); 43+,
for the inclusion of web-condition-responsive dryer control; 115,
for the conveying of the web over or around drying drums; 158, dryer-and-tenter-structure

This subclass is indented under subclass 89. Spreader in which each of the elements of the series is
constituted by a pair of jaw members movable relative to one another
to converge upon and grip opposite sides of successive cloth edge(s)
increments and to diverge to release the edge(s).

the traveling edge-retaining elements in their series at a part thereof,
or connected thereto, to effect or control said convergent or divergent
Note. Mere reference to the clamp manipulation in the disclosure
of the tentering operation, without even illustration of the manipulator,
will not serve for placement by disclosure alone of an original
patent into this subclass rather than parent subclass 93.

subclass and further including means activating the pin members
of the series for cloth-edge penetration responsive to displacement
of that edge from the clamp-like feeler member of the series.
This subclass is indented under subclass 88. Spreader including rotatable means dimensioned and positioned
to engage the traveling web increment at the selvage area only and effecting
outward spreading of the selvage by either (a) being mounted for
rotation about an axis parallel to the face of the web and at an acute
forward angle in the direction of the web travel or (b) mounted
for rotation about said parallel axis and being of such surface
configuration as to direct said selvage outwardly.
This subclass is indented under subclass 87. Spreader comprising a rotatable cylinder extending substantially
continuously thwart the entire width of the running length of cloth
and constructed to compel successive running half-width increments
oppositely outwardly from the common center.
for spreader roll structure extending across the
entire width of the running cloth web; see, for example subclass 100
or 102+ for spreader roll structure made of a plurality
of contiguous members extending clear across the width of the running
web; which members may include one which is central and merely passively
rolling with the cloth and outside ones acting to spread opposite
outside half increments.
This subclass is indented under subclass 99. Spreader in which the rotatable cylinder includes members
which are coaxially shiftable relative to one another to provide
for (mutually opposite) outward displacement of the members correspondingly
to spread the cloth (half-width) increments.
This subclass is indented under subclass 99. Spreader of a configuration increasingly to diverge from
the axis extending between its end supports, whereby the oppositely
outward spreading of the half-width increments of the running web
occurs by being: (a) wedge over the resulting intermediate bulged
configuration; or (b) directed outwardly by contact with a respective
one of resulting pair of oppositely forwardly angled members or
for spreader structure in which each one of a pair
of forwardly obliquely angled members are located at respective
opposite selvages only (rather than substantially coextensively athwart
the entire width of the running length of the web.)
This subclass is indented under subclass 102. Spreader in which the separate coextensively contiguous
members constitute a multiplicity; i.e., a plurality between each
opposite end to the common center, each member being self-adjustably
movable relative to the rest to permit rotation thereof notwithstanding
the overall bowed configuration.
This subclass is indented under subclass 99. Spreader in which the opposite outward spreading of the
running half-width increments is effected by contact with a respective
one of a pair of helical configurations about the periphery of the
roller, each winding oppositely outwardly from their common center.
This subclass is indented under subclass 71. Structure further provided with means to apply heat to the
fabric web, or to subject the web to a gaseous (i.e., steam) treatment;
e.g., to dry the fabric, etc.
Note. By its position at the foot of this schedule (the last
coordinate under subclass 71), this subclass can accept as an original
the combination with a heater or dryer of cloth expanding structures which
are not spreaders. This subclass is available, however, for the
cross-referencing of the combination of a heater or dryer with spreaders
of general construction; i.e., other than those of subclasses 81
