Procedure an apparatus for testing
a material m~nufacturad in web form
The present invention concern a procedure and an ~ppqratuY for
testing a material that it manufactured in web form, in connection
with a process, in said procedure a sample brine taken from the
material for testing.
The properties of Motorola manufact d in web Norm are tested in
connection both of their manufacturing and of their use in order to
ensure the quality of the material. Materials of this type which
are manufactured in web form are e.g. viscose, cellulose, paper,
cardboard, fabric, and equivalent materials of which the character-
i3tiC9 should be constant and uniform in quality.
when procedure end apparatus known in the art are being applied,
these sty are performed by trained examiner in a separate, us-
ally air-conditioned laboratory, to which the samples are conveyed.
The samples are tasted with a separate testing device made for each
characteristic. Of the replicate measurements of the particular
characteristic, obtained with each device, the means and standard
deviation are calculated and the results are used in controlling
the quality.
In connection with manufacturing it particular, the test result
should be made available for us as soon a over possible, but -when
in procedures and devices known in the art it may take a long
time before the text roulettes are available. Present procedures and
device have furthermore the drawback thaw they require an air-con-
ditioned laboratory room and special personnel to make the test
and to treat the results. Moreover the characteristic of the
ample may ah Noah while the sample is brine transported and manipu-
latticed for the various testing devices. furthermore, existing text-
in device are separate and an individual sample has to be pro-
pared for each testing device. Moreover, e~istins apparatus it
.
inoonveniellt to manipulate.
The object of the invention it to provide a procedure and a means
for testing material that it manufactured in Deb form and an ape-
Wright for applying the procedure, drawbacks of the procedures and
apparatus of prior art being eliminated with their aid. It it a
particular object of the invention to provide a procedure and Papa-
fetus by the aid of which the Rosetta of testing can by made avail-
able within a short period, whereby these results become usable in
process control immediately without time delay. It it a further
object of the invention to provide a procedure and apparatus by
which the material texts are performed on one sample and the manic-
elation time of tune sample prior to its being conveyed to be tested
being short. Furthermore, it is an object of the invention to pro-
vise an apparatus for applying the procedure by the aid of which
the characteristics desired can be tested from one sample and by
utilizing which the number of characteristics to be tested can be
modified and varied depending on the purpose.
The aim of the invention is attained by a procedure and an appear-
tusk mainly characterized by that thigh ha been elated it the
claim section.
In the procedure of the invention, a sample it taken from the
material for tasting and the sample it inserted in the input unit
of the testis apparatus disposed it the immediate vicinity of the
process. The apparatus it air-conditioned with the aid of an air-
conditioning mean in order to maintain desired moisture content
and temperature of thy sample. Subsequent to air conditioning the
sample it with the aid of a transporting means transported, under
control by a control means, into the basic unit and to the testing
devices disposed therein which text various properties of the
material, and the properties of the malarial arc tested by the
testing devices. The results ox testing sure immediately given out,
whereby they become available shortly after the sample was taken.
Moreover, the different tests are made from owe end the same sample
in succession in the basic unit of the testing apparatus located
:
I
immediately adjacent to the process, whereby the ampule monopoly-
lion time before testing will be minimized and all results of test-
in are obtained within a short period of time. The apparatus it
placed in the vicinity of the manufacturing process or operational
prows to be tested 9 and no particular examination room is no-
squired or the tests. The process operating personnel is enabled to
make use of the results of testing obtained by the aid of the pro-
seedier, without requiring any spscific9 prolonged training. All
testing events are fully automated, whereby the apparatus it easy
to operate, an likewise the print-out from the apparatus take
pleas automatically and thy results are easy to read.
Depending on the kind of the material manufactured in web form, the
samples may have either roll or sheet form no thy input dsvic2 has
been provided with members enabling a roll-shaped or sheet-shaped
sample to be introduced in the basic unit. The sample area it
intsgrat~d with the aid of an sensor device as the sample is being
fed prom the input station into the basic unit. It it ensured in
this connection that thy breadth of the sample is sufficient for
obtaining correct test results, and at the same time are noted any
tear or hole that may occur in the sample and which affect the
text results.
The apparatus of the invention comprise 8 basic unit constituted by
a housing, an air-conditioning means and testing devices accommo-
dated within the basic unit, an opsnabla input device in which the
sample can be placed and which connect to the basic unit, triune-
porting moans disposed in the basic unit and disposed to transport
the sample from one testing device to the other a controller for
controlling the operation of thy apparatus and for processing thy
results, and an output or printing means for displaying the results
of the test. The functions of the controller are provided by a
computer, which controls the operation of the air-co~ditioniD4
means, the transporting mean and the testing Davis and processes
the results from the tine devices, and transmits the results to
an output unit, which is a display terminal, a printer and/or
plotter, or another output (printout) means known in itself in the
art.
The appar~kus include, placed immediately adjacent to the input
aperture between the input device and the basic unit, a sensor
device for integrating the ampule area And or monitoring the
sample feed-in operation. The ~en90r Davis consists of a meaty
which in a manner known in itself in the art either optically,
electrically or in other way known in the art ob~ervas thy sample
without touching it.
The transporting means transports the sample through the basic
unit, through the testing devices. The transporting means consist
to advantage of an endless belt disposed to extend from the immedi-
ate vicinity of the input mean to adjacency of the basic units
opposite wide and provided with gripping members. For gripping mom-
biers may be used structure known in themselves in the art, e.g.
3piks-like, hook-like, suction cup-like or equivalent gripping mom-
biers. with the aid of the transporting means, thy sample is without
cutting it off carried through the basic unit and the testing
devices provided in thy basic unit test the sample or different
properties as the sample is being conducted through these devices.
The basic unit it preferably arranged to be openable for cleaning.
It is then easy without effort from the enclosed basic unit to
remove any sample pieces left in the basic unit in connection with
tests. However, the main part ox the sample Deb runs through the
apparatus and departs from the apparatus after the texts, whereby
only minimal quantities of the sample material remain in the basic
unit.
In the basic unit it accommodated at least one, preferably a plus
reality of testing devics3 testing various prop9rtie9- Each t~9tinB
device constitutes an independent unit and it intended to test a
given characteristic of the material. These testing device units
era detachably mountable in the basso unit and, a required, a-
changeable for another unit. It it thus possible to increase or
reduce the number of testing device unit in accordance with change

in condition, and they may, it desired, be Canada against other units, whereby the apparatus it easily modlfiabl0 to meet
different purposes and requirements. Such testing dHvice3 include
tensile measuring, tear measuring, burst measuring, optic
eel measuring, smoothness erring, porosity measuring,
specific gravity measuring, moisture content measuring and caliber
Myron units. These unit have been duped to operate
automatically under control by the controller and to last for
desired propriety.
