PROVIDIUNAL SITUIFICATION.
Improvements in Sheets of Paper Specially Applicable for being
made into Covers for Enclosing Documents and Papers.
I, ADOLF JEENEL, of 4, Klosterstrasse, of Breslau, in the Province of Silesia,
German Empire, Engineer, dó hereby declare the nature of this invention to be as
follows:-
This invention refers to sheets of paper, especially auch that are comparatively
thick and are suited to serve as covers for, or to receive, acts, documents, and other
papers which must be sewn or otherwise fixed to the back of the cover.
In such cases the backs of the covers are strengthened by glueing or otherwiso
occuring to them one or more strips of paper; but according to my invention the
strips are not any moro attached to the backs as separate pieces, but they are made
integrally with the sheets proper on manufacturing these latter.
The object of my invention is to do away with the loss of labour and time caused
by affixing the separate strips to the backs, and I attain that purpose by producing
the strips, or, more precisely, the strengthened parts, simultaneously with the
sheets proper, or by aid of any of the machines used for the mechanical treatment
of said sheets.
In order to make my invention more clear, I refer to the accompanying drawing,
in which:
Figure 1, is a section through a sheet of paper made according to my invention,
and
Figure 2, shows that sheet formed into a cover for a number of acts, documents
and other
papers.
A is the sheet of paper, A' is the strengthened part or strip which is to form
(Figure 1) or forms (Figure 2) the back. I wish it, however, to be understood that
I do not limit myself to strengthening only such a part as A¹, but also another part
or other parts of the sheet may be strengthened in the manner in question; and
instead of using such sheets as covers for acts and the like I may employ them in
any other way as may be requisite for any special purpose.
Dated this 1st day of April 1897.

Improvements in Sheets of Paper Specially Applicable for being
made into Covers for Enclosing Documents and Papers.
I, ADOLF JEENEL, of 4, Klosterstrasse, of Breslau, in the Province of Silesia,
German Empire, Engineer, do hereby declare the nature of this invention, and in

page_text: what manner the same is to be performed, to be particularly described and ascer
tained in and by the following statement:-
This invention refers to sheets of paper, especially such as are comparatively
thick and suited to serve as covers for, or to receive documents, and other papers
for filing and other purposes and which must be sewn or otherwise fixed to the
back of the documents.
Hitherto the backs of such covers have been strengthened by glueing or other-
wise securing to them one or more strips of paper; but according to my invention
strips of this character are not attached to the backs as separate pieces, but are
made integrally with the sheets proper during the manufacture of said covers.
The object of my invention is to do away with the loss of labour and time caused
by affixing the separate strips to the backs, and I attain this purpose by producing
the strips, or, more precisely, the strengthened parts, simultaneously with the
sheets proper, i.e. the strengthened parts are manufactured integrally with and
form one piece with the before mentioned sheets.
I will proceed to describe, how this result may be attained.
Firstly I may dispense with a paper making machine and employ a longitudinal
sieve possessing or provided with longitudinal recesses at such parts where tho
sheets are required to be thicker.
It will be clear that, when the upper surface of the mass within the sieve has been
smoothed off, that the material in the recesses will strengthen the sheets at the
places in question, and thus effect the increased thickness as desired.
Secondly I may strengthen the said sheets by providing same with extra-strips
and attach the said strips by the aid of a paper-making machine.
This process is not embodied in my claim and furthermore the said process is
known, so that I abstain from describing the same beyond stating, that I can attach
such strengthening strips of paper or pulp to the sheets of paper pulp by pressing
the said sheets, together with the strips, between the rollers of the paper making
machine, and by gradually expelling the moisture I can so secure the strip to tho
sheet that the same becomes an integral portion of the said sheet.
In order to make my invention more clear, I refer to the drawing sent in with
previsional application, in which:
Figure 1 is a section through a sheet of paper made according to my invention,
and
Figure 2 shows that sheet formed into a cover for the reception of any suitable
number of documents and other papers.
A is the sheet of paper, A¹ is the strengthened part or strip which is to form
(Figure 1) or forms (Figure 2) the back. I wish it, however, to be understood that
I do not limit myself only to strengthening such part (as A') but also any other
part or other parts of the sheet may be strengthened in the manner hereinbefore
described; and instead of using such sheets as covers for documents or the like, it
will be clear, that I may employ my invention to produce for instance covers for
books, and in short, for filing purposes generally.
Having thus fully and particularly described the nature of my said invention, and
in what manner the same is to be performed, I declare that what I claim is: -
As a new industrial product, adaptable to many practical and optional uses:
Sheets of paper having strip like strengthened portious, made integrally with, or
forming one piece with the before mentioned sheets, substantially and for the
purpose as described.
