COMPLETE SPECIFICATION.
Improved Machine for Folding the Edges of Ribbons, Tapes and the
like.
We, BRUNO FUCHS, 123, Reichenberger Strasse, Lock-smith, and LEO MAKEL,
32, Prenzlauer Strasse, Detective, all in Berlin, Germany, 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 a machine for folding or bending over the edges
of ribbons, tapes, and the like, whereby fraying is prevented.
--
The invention is illustrated in Figure 1 in elevation viewed from behind:
in Figure 2 in side elevation viewed from the left.
The apparatus may be driven by the crank handle a or by a belt passing over
the pulley b. Either of these devices is keyed upon the horizontal shaft of the
upper roller
c, preferably of wood, and which sets the lower roller d in motion
when revolving by frictional contact. The axles of the rollers are supported
in the frame e which can be attached by means of clamping-screws for the like
to the edge of a table. Between the roller c and d the ribbon or the like which
is to be folded is inserted and drawn through by the revolution thereof after it
has passed through the folding device proper which is placed in front of the said
rollers and secured by the screws g.
The apparatus consists of the folders which are not new in themselves but
are shaped and work exactly like the ordinary hemmer or folder of the sewing
machine. These folders are provided with helical projections has shewn in
perspective in Figure 3, which folding devices slide upon the horizontal sup-
port and may be adjusted thereon by means of the nuts l. This adjustability
is necessary in order to admit of ribbons and the like of various breadths being
folded by means of one machine. The folding devices i are provided, inside
and below, with apertures m to permit the material to pass under them. In
order to hold down the material between the folders i a number of plates n are
provided with a vertical slot each and adjusted upon the screw bolts o in such
a manner that according to the width of the ribbon the requisite number thereof
can be let down; these plates are illustrated on a larger scale in Figure 4 in
elevation. In square apertures in the two middle plates is placed the square
rod passing upwards through the holder p, which rod prevents the plate-
block from turning. A spiral spring r is provided to press the plate-block
downwards.
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 :-
The improved folding-machine, characterized by the arrangement of two
sliding adjustable folders (i) in combination with a plate-block formed of any
convenient number of adjustable plates, which block is normally depressed by
means of a spring (r) and is combined with two pressing and drawing rollers (c
and d) suitably driven, substantially as illustrated and described.
