The present invention relates to collars and
particularly to collars made of paper, cardboard
' and similar materials, and to a process of mak
ing the same.

Collars which are made of materials that are
tained which is‘ produced'entirely by machine
and with less effort and within a- shorter time
than was possible by the known methods since
each collarv is not individually’ folded and glued .
into ?nal form after beingv cut from the blank,
. easily subject to wear and tear, such as for ex
but a large series of collars are so ?nished either
ample collars made of paper or cardboard, are ' simultaneously or in continuous operation. _
usually reinforced at their front portions and‘
the ?aps where the two sides of the collar are
10 fastened. together and secured to a shirt. The
known constructions provide for this purpose
suitable extensions. of the front portions when
the collar is cut or stamped out of the blank.
These extensions are then folded back and glued
15‘ or otherwise secured to the inside of the collar
After the collars 4 have been folded, glued
and cut from the blank 2, the‘ cut edges ll may
be coated with a layer of varnish or similar
material whereby the paper, cardboard orthe
like of which the collars are made, is protected
from splitting along the cut edges I4. Such a
coating also serves to make the fact that the
material is out along edges I2 unnoticeable and
, "i. separately for each individual ‘collar, either man- _ the edges l2 less conspicuous so that the collar 15

The “object of the present invention is to over
or similar expensive materials.
20 come these disadvantages of the prior -'art, to
facilitate the production of collars and to save
time and labor in ‘the manufacture thereof.
. Another object resides in a new process of mak

portions-6, gluing them to the ;blank 2, cutting 20
the shape of the collar 4 out of the blank, punch
ing the button ‘holes l0, and coating the cut
ing collars, particularly collars made of ‘paper edges ii of the collar, provided thi's'additional
or like material. l
‘ 'step appears necessary, are preferably performed
A further object resides in producing a collar in one continuous operation by one and the
of paper or similar materials which resembles a
collar of linen or the like to such an extent
as not to bedistinguishable‘ therefrom.

Still another object consists in a method of
?nishing such collars along their cut edges by
coating them with a layer of varnish or‘ similar

same machine. However, it'is also possible to
execute the method in several operations by a
series of machines. No matter which procedure
is‘ followed, the difficult and time-wasting op-, 30
eration of folding the reinforcing portions indi
vidually. for eachcollar and then gluing them to
the rear sides thereof is avoided.
These and other objects of the invention will
