MACHINERY FOR PLEATING AND RENDERING PERMANENT UPRIGHT OR ACCORDION PLEATING OR KILTING
Year: 1884

page_text: I HOWARD TROTMAN of 228 Euston Road, in the County of Middlesex Costumo
Manufacturer, do hereby declare the nature of my Invention for MACHINERY
FOR PLEATING AND RENDERING PERMANENT UPRIGHT OR ACCORDION PLEATING OR
KILTING to be as follows:-
An improved Machine for pleating textile fabrics and consists of 3 separate
parts.
1st The Pleater which consists of 2 Blades which lay and fold the Material
alternately.
2nd A heated rectangular chamber by the agency of which the folds are set.
3rd A cooling chamber in which the pleated fabrics or material is retained till
cold thereby rendering the set of the pleat or fold permanent.
A fuller description of which is as follows.
An improved machine for pleating textilo fabrics by pleating the same thro the
agency of two blades and pressing the folds into a rectangular chamber by the
blades under which it is placed.
The said chamber may be further described as a rectangular tube in horizontal
sections, the first of which receives the pleated fabric and damps the edges of the
pleats the second section heats the edges of the pleats so damped and the third
dries and cools the pleats treated as aforesaid resulting in a permanent set or fold.
The pleaters or folders consist of two Steel blades the full length of the machine
these blades are fixed in Iron backs to which movement is imparted by small
double cams one set of which cams retires while the other raises the blades the
said cams are on spindles running the whole length of the machine-The blades
aforesaid are hinged at the bottom of the machine by the agency of rods which
pressing thro a rocking bar permits to the said blades a slight curvilinear motion
between the retiring of the blades and their laying of the fold such motion being
imparted by the cams aforesaid when the spindles on which they are fixed are
turned.
In the first position the blades lie one on the top of the other the fabric being
inserted between them the under blade is then drawn back, raised, and carried
forward and taking the fabric with it is made to lie on the blade which before was
on the top and which now in its turn is drawn back raised and carried forward
taking the fabric with it for the next fold or pleat and laying it on the top.
This alternate hand over hand action of the blades with a slightly curvilinear
motion results in the folding back and forth of the fabric by the blades which
retire and then returning to their bed lay a fold (or pleat) alternately.

Manufacturer do hereby declare the nature of my Invention for PLEATING AND
RENDERING PERMANENT UPRIGHT OR ACCORDION PLEATING OR KILTING and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
An Improved Machine for pleating textile fabrics or other materials by folding
the same thro: the agency of two blades and pressing the folds into a rectangular
chamber by the blades under which it is placed.
The said Chamber may be further described as a rectangular tube in borizontal
sections, the first of which receives the pleated fabric and damps the edges of the
pleats The second section heats the edges of the pleats so damped, and the third
dries and cools the pleats treated as aforesaid resulting in a permanent set or fold.
The pleaters or folders consist of two steel blades the full length of the machine
these blades are fixed in Iron backs, to which movement is imparted by small
double cams one set of which cams retires while the other raises the blades, the
said Cams are on Spindles running the whole length of the machine The blades
aforesaid are hinged at the bottom of the machine by the agency of rods which
passing freely thro a rocking bar permits to the said blades a slight curvilinear.
motion between the retiring of the blades and their laying of the fold such motion
being imparted by the cams aforesaid when the Spindles on which they are fixed
are turned.
In the first position the blades lie one on the top of the other the fabric being
inserted between them, the under blade is then drawn back, raised, and carried
forward, and taking the fabric with it is made to lie on the blade which before
was on the top and which now in its turn is drawn back, raised, and carried
forward taking the fabric with it for the next fold or pleat and laying it on
the top.
This alternate hand over hand action of the blades with a slightly curvilinear
motion results in the folding back and forth of the fabric by the blades which
retire and then returning to their bed lay a fold (or pleat) alternately.

ing now particularly described and ascertained the nature of my said
tion and in what manner the same is to be performed I declare that what
im is:
laim as my Invention the folding or pleating of materials or textilo fabrics by
tomatic action of 2 blades which press the folds or pleats into a rectangular
er over or against which they are placed in which chamber the edges of the
nay be damped or steamed and heated or dried.
