I FREDERICK ROLLASON, of Foleshill, Coventry, in the county of Warwick, Ladder
Web Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to an improved method of manufacturing ladder webs. for
Venetian blinds of that class known as woven throughout," that is to say, in
which the cross straps to support the laths are woven into the main or longitudinal
tapes. As at present manufactured, these cross straps are sometimes liable to be
drawn out of the main tapes, and the object of my improvement is to render this
impossible. According to my invention, the warp of which the cross strap is to be
made, is woven into the main or longitudinal tape at two distinct points at each end
of the cross strap, the intervening portion between the two points being woven in
the ordinary way as in forming the strap itself. The ends of the strap are-in this
way doubly spliced into the main tape, the two splices being separated by a woven
portion, whereof the weft prevents the drawing out of the splice.

Web Manufacturer 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 :—
My invention relates to an improved method of manufacturing ladder webs for
Venetian blinds of that class known as t woven throughout," that is to say, in
which the cross straps to support the laths are woven into the main or longitudinal
tapes.
As at present manufactured these cross straps are sometimes liable to be drawn out
of the main tapes, and the object of my improvement is to render this impossible.
According to my invention the warp of which the cross strap is to be made is
woven into the main or longitudinal tape at two distinct points at each end of the
cross strap, the intervening portion between the two points being woven in the
ordinary way as in forming the strap itself. The ends of the strap aro in this way
doubly spliced into the main tape the two splices being separated by a woven portion
whereof the weft prevents the drawing out of the splice.
The invention and method of manufacture are further explained in reference to
the accompanying illustrations in which figures 1 and 2 are side elevations at two
different stages before and after separation, and figure 3 is a sectional plan on line mn
of figure 1, showing the straps which are represented by dotted lines in their
connection with the upper tape, removed in the figure. For distinction the parts
are shown exaggerated in figures 1 and 2.
a a are the main longitudinal tapes and 6 6 the cross straps which are continuously
and simultaneously woven by separate and distinct wefts; at suitable intervals the
warp of each strap bis woven at the two distinct points 1 and 2 for any required
distances 1, 1ª, 2, 2ª, into the main tape by the weft forming the main tape.
The part c intervening between 1ª, and 2 is a separate unattached portion woven
in the same way as the rest of the strap,-and-the woven in portions cannot be pulled
or drawn out of the main tapes being locked as it were by the part c.
From the
points 2 the warp of the straps 6b crosses to the opposito main tape and is woven i
thereinto again in the same manner.
After the ladder is woven as in figure 1 the warp of the strap is cut at the points d
and the ends of the warp trimmed off.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
In the manufacture of ladders for Venetian blinds weaving the ends of the cross
straps into the main or longitudinal tapes at two distinct points for any required
distance leaving an intervening unattached part woven in the same way as the cross
strap itself as and for the purposes hereinbefore setforth.
