THREAD REEL

BOBINE

English Abstract

ABSTRACT OF THE DISCLOSURE
A thread reel is previously known which at its two
ends is provided with two flanges arranged beside each
other and between which the tread is intended to be
attached. According to the invention the two flanges
arranged beside each other are situated at a small distance
from each other and the inner flanges are of such a weak
construction that they will be pressed with their
peripheries into contact with the outer flanges by means
of the thread applied on the reel.

Claims

The embodiments of the invention in which an
exclusive property or privilege is claimed are defined
as follows:
1. A thread reel comprising a cylindrical part (1)
having an outer flange (3) (4) integral with each end
of said cylindrical part, an inner flange (5) integral
with said cylindrical part and spaced from and adjacent
to one (3) of said outer flanges, the spacing between
said adjacent inner (5) and outer (3) flanges being some-
what greater than the thickness of the thread to be wrapped
about said cylindrical part of said thread reel, said
inner flange being of sufficiently flexible construction
whereby its peripheral edge (7) is pressed into contact
with the outer flange (3) by the thread as said thread is
wrapped around the cylindrical part (1) of the reel between
said outer flange (4) and said inner flange (5) to substan-
tially the height of said inner flange (5).
2. The thread reel as defined in claim 1 including
a second inner flange (6) integral with said cylindrical
part and spaced from and adjacent to the other (4) of
said outer flanges, the spacing between said adjacent
inner (6) and outer (4) flanges being somewhat greater
than the thickness of the thread to be wrapped about said
cylindrical part of said thread reel, said second inner
flange (6) being of sufficiently flexible construction
whereby its peripheral edge (8) is pressed into contact
with the outer flange (4) by the thread as said thread
is wrapped around the cylindrical part (1) of the reel
between said inner flanges (5) and (6).

3. The thread reel as defined in claim 1 wherein
the interfacing sides of said outer flange (3) and said
inner flange (5) are provided with integral staggered
projections (9) (10) along the periphery of said flanges
for retaining the periphery of said flanges (3) and (5)
in contact with each other when said thread is wrapped
about said cylindrical part (1) to substantially the height
of said inner flange.
4. The thread reel as defined in claim 3 wherein
said interfacing sides of said outer flange (3) and said
inner flange (5) are also provided with recesses adapted
to receive said staggered projections on the opposite
interfacing side.
5. The thread reel as defined in claim 2 wherein the
interfacing sides of said inner flange (6) and said outer
flange (4) are provided with integral staggered projections
(9) (10) along the periphery of said flanges for retaining
the periphery of said flanges (4) (6) in contact with each
other when said thread is wrapped about said cylindrical
part (1) to substantially the height of said inner flange,
said interfacing sides of said outer flange (4) and said
inner flange (6) also being provided with recesses adapted
to receive said staggered projections on the opposite
interfacing side.
6. The thread reel as defined in claim 5 wherein
said integral staggered projections are ball shaped.
7. The thread reel as defined in claim 5 wherein
said integral staggered projections are radially directed
bars.

Description

8075
The present invention relates to a thread reel
which least at one end is provided with two flanges arranged
beside each other and between which the thread is intended
to be attached. Characteristic of the reel is that the two
flanges arranged beside each other are situated at a small
distance from each other, and the inner flange is o~ such
a construction i~e. sufficiently flexible that it will be
pressed with its periphery into contact with the outer
flange by means of the thread applied on the reel.
As the distance between the two flanges arranged
beside each other can be made greater than the thickness
of the thread without jeopardizing the ability of the
thread reel to attach the thread, the thread reel accor-
ding to the invention is easily manufactured, especially
as it consists of plastic material.
The invention will be described more fully below
with reference to the accompanying drawing which shows an
embodiment of the reel chosen by way of example and in
which:
Fig. 1 shows a longitudinal section of the reel;
Fig. 2 shows likewise a longitudinal section of
the reel with thread applied on it; and
Fig. 3 is a top view showing on a larger scale a
portion of the periphery of the flanges.
The thread reel consists of a cylindrical part 1
on which the thread 2 is intended to be laid. The cylin-
drical part 1 is defined at its two ends by end flanges
3 and 4.
At least at one end the thread reel is provided
~, - 1 -

with an additional flange 5 and 6 respectively. The addi-
tional flange, which is situated inside the end flange 3
and 4 respectively, is of such a construction that it can
spring relative to the end flange 3 and 4 respectively
for retention of the thread 2.
In the embodiment shown in the drawing and prefer-
ably consisting of plastic material, the end flange 3 and
4 is situated at a distance from the additional flange 5
and 6 respectively which distance is somewhat greater
than the thickness of the thread 2. The additional flange
5 and 6, i.e. the inner flange, is of such a construction
that it will be pressed with its periphery 7 and 8 into
contact with the outer flange 3 and 4 respectively by
means of the thread 2 applied on the reel, as is apparent
from Fig. 2. With this arrangement there is created an
attachment means for the thread 2. The effect produced
by the thread 2 on the inner flanges 5 and 6 is independent
of whether the thread 2 is laid in parallel or cross-wise.
The retaining effect may be increased by providing
relatively staggered projections 9 and 10 on the periphery
of the interfacing sides of the two flanges arranged beside
each other 3, 5 and 4, 6 respectively. According to the
embodiment shown in Fig. 3 the projections 9 and 10 are
ball-shaped but in another embodiment the projections
may consist of radially directed bars or the like. The
projections 9 and 10 may, if desired, coact with recesses
on the opposite side.
