Improvements in Machines for Raising a Nap or Pile upon Fabrics.
We, ROBERT SELLERS, HENRY HEATON, and HARRY THORNTON, and THE
PREMIER RAISING MACHINE COMPANY LIMITED, Prospect Mills, Scholes, near
Cleckheaton, in the County of York, Machine Makers, do hereby declare the
nature of this invention to be as follows:-
-
This invention relates to improvements in machines for raising a nap or pile
upon all classes of fabrics on which a nap or pile is required to be raised, the
object being to provide efficient means for raising such pile or nap in the direction
of the weft of the fabric.
Our invention consists essentially in the use of a card covered roller or rollers,
so mounted in bearings that its own weight keeps it in contact with the fabric
to be raised and which is given a rotary motion in the same direction in which
the fabric moves at or about the same superficial speed and, in addition, a rapidly
reciprocating motion across the fabric in the direction of the weft.
In carrying out our invention we provide a roller, or number of rollers, of a
suitable character and cover them with card cloth of such a construction as will
suffice to raise the pile. Each of these rollers is mounted in bearings provided
with slots to enable the weight of the roller to bring it into contact with the
fabric to be raised. The extent or depth of contact can be regulated at will by
means of screws or the like but in any case the screws are so aranged as to
allow the roller or rollers, to be easily pushed back when the piccing of the
fabric comes round and so avoid damage to the fabric or roller. When the
piccing has passed, the roller assumes its normal working position. Each roller
is rotated at or about the same superficial speed as the cloth by suitable mechanismi
and in the same direction and is also given a rapidly reciprocating motion in
the direction of the weft of the fabric, by any suitable mechanism, to effect the
raising of the nap or pile. We preferably mount each roller in close proximity
to a pair of rollers over which the fabric is conducted, such rollers being also
preferably card covered, though any other arrangement of rollers will suffice
providing they will hold the fabric securely in position without buckling.
We may combine such roller or series of rollers with one or more flat card
surfaces rapidly reciprocating in the direction of the warp of the fabric being raised
such for instance as those shown in the Specification of Patent Number 14,263 of
the year 1896, granted to Robert Sellers, one of the present applicants. Or we
may combine such roller or series of rollers with other nap raising rollers which
have not a longitudinal motion.

We, ROBERT SELLERS, HENRY HEATON, and HARRY THORNTON, and THE
PREMIER RAISING MACHINE COMPANY LIMITED, Prospect Mills, Scholes, near
Cleckheaton, in the County of York, Machine Makers, do hereby declare the
nature of this invention and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement:
This invention relates to improvements in machines for raising a nap or pile
upon all classes of fabrics on which a nap or pile is required to be raised, the
object being to provide efficient means for raising such pile or nap in the direction
of the weft of the fabric.
Our invention consists essentially in the use of a card covered roller or rollers,
so mounted in bearings that its own weight keeps it in contact with the fabric
to be raised and which is given a rotary motion in the same direction in which
the fabric moves at or about the same superficial speed and, in addition, a rapidly
reciprocating motion across the fabric in the direction of the weft.
The invention will be fully described with reference to the accompanying
drawings which show the manner in which our invention may be carried into
effect and in which
Fig. 1 is a partial sectional elevation and
Fig. 2 a partial front view.
In carrying out our invention we provide a roller, or number of rollers a, of a
suitable character and cover them with card cloth of such construction as will
suffice to raise the pile. Each of these rollers is mounted at each end in bear-
ings forming part of or attached to the frame c of the raising machine and
provided with slots d to enable the weight of the roller to bring it into contact
with the fabric e to be raised. The shafts of the rollers pass through the slots d
and may rest against blocks such as f. capable of being moved along the slots,
the lower end of each block passing through the bearing brackets 6. The extent
or depth of contact of the wire surface of the rollers a with the fabric to be raised
can be regulated at will by means of screws or the like passing through the
blocks but in any case the screws are so arranged as to allow the roller or
rollers, to be easily pushed back by the fabric when the piecing of the latter
comes round and so avoid damage to the fabric or roller. When the piecing has
passed, the roller assumes its normal working position. The cloth or fabric e
to be raised is shown as being passed round card covered rollers h and plain guide
rollers in a similar manner to that referred to in Patent No. 14,263 of the
year 1896 granted to one of the present applicants, though it may be guided in
any other suitable manner provided the cloth is held taut to enable the rollers a
to act efficiently on it. The cloth is traversed over rollers and i at a definite
rate in the direction of the arrow and each roller a is mounted preferably in or
about the position shown and is rotated at or about the same superficial speed
as the cloth, and preferably in the same direction, by any suitable means such
as, say, spur wheels j fixed on the shafts of one of each pair of rollers h¹ and
gearing with similar wheels on the shafts of rollers a. Each roller a is also
given a rapidly reciprocating motion in the direction of the weft of the fabric,
by any suitable mechanism to effect the raising of the nap or pile.
We may combine such roller or series of rollers with one or more flat card
surfaces rapidly reciprocating in the direction of the warp of the fabric being
raised, such for instance as those shown in the specification of Patent Num-
ber 14,263 of the year 1896, granted to Robert Sellers, one of the present

page_text: applicants. Or we may combine such roller or series of rollers with other nap
raising rollers which have not a longitudinal motion.
By means of our invention we obtain an efficient raising of the pile on fabrics
in the direction of the weft by means of rollers.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
what we claim is:.
1. In machines for raising nap on fabrics the use of one or more card covered
rollers having a rotary motion in the same direction (preferably) in which the
fabric moves and at or about the same superficial speed as the cloth and a
rapidly reciprocating motion across the fabric substantially as described.
2. In machines for raising nap on fabrics the combination of one or mord
rollers such as a operated as described with guide rollers such as and i sub-
stantially as described.
3. In machines for raising nap on fabrics the combination of one or more
rollers such as a operated as described with one or more rapidly reciprocating
flat card surfaces such as referred to in Patent 14,263 of the year 1896.
4. The improved means for raising nap on fabrics substantially as described
and shown with reference to the accompanying drawings.
