                April 1, 1960
                          THE INSTITUTE OF PAPER CHEMISTRY

                                 Appleton, Wisconsin



             This report is supplementary to Progress Report 63 of the base-

line study on corrugating medium entitled, "Continuous evaluation of cor-

rugating medium" which provides a program whereby participating mills have

the opportunity to submit rolls of medium on a regular weekly schedule for

evaluation with regard to physical characteristics of the medium and of

the single-faced board made from the medium6     Specifically, each medium is

evaluated for caliper, basis weight, and Concora flat crush      In addition

each medium is fabricated into A-flute single -faced corrugated board on

the Institute's corrugator to determine its runability in terms of speed

and tension, and the single-faced board obtained at maximum speed with

minimum tension is evaluated for its flat crush strength


             This report is an extension of the baseline study described above

and is concerned specifically with the caliper and uniformity of caliper of

the single-faced board fabricated from each roll of medium      Uniformity of

caliper is generally considered to be another facet of the criteria used

to evaluate the runability of corrugating medium, and the Technical Committee

of the Fourdrinier Kraft Board Institute, Inco, has requested that a measure-

ment of the uniformity of caliper be included as a part of the evaluation

given each    roll of corrugating medium0



          The evaluation of the caliper and uniformity of caliper of the

single-faced board made from each roll of corrugating medium was carried

out using the five circular specimens that were subsequently tested for

flat crush strength0    Each specimen was five square inches in area.   They

were cut at intervals of approximately two feet along the central portion

of a strip of the single-faced board fabricated at maximum speed and

minimum tensions     On each of these five specimens, caliper measurements

were made on five consecutive flutes and the caliper difference between

consecutive flutes    was calculated, there being four calculations of

differences for each specimen.     The twenty-five caliper measurements (five

calipers on each of the five specimens) were averaged and are reported as

the caliper for each sample of medium     Likewise, the twenty caliper differ-

ences between consecutive flutes (four caliper differences on each of the

five specimens) were averaged, and the maximum, minimum, and average values

are reported for each sample of corrugating medium.


            The instrument for measuring the caliper of individual flutes

of single-faced board consists of a bench-type thickness gage with a presser

foot 3/8 inch in diameter and an anvil consisting of a plane circular sur-

face 2 inches in diameter      The presser foot is attached to a dial indicator

which can be read to OoOOOl inch     The load on the presser foot is 100 + 10

grams     A caliper determination is made by inserting each five-square-inch

circular specimen between the presser foot and the anvil so that the foot

rests on the second flute from one end of the specimen without touching either

of the adjacent flutes      The 3/8-inch diameter of the presser foot permits it

to contact only one flute with ease The specimen is pressed gently against

the anvil, and the reading is then recorded0    As mentioned previously, five

consecutive flutes through the center of each specimen are calipered in this

wayo    It should be emphasized that these calipers may not necessarily corres-

pond to regular caliper measurements because of differences in load and other

variables

             Caliper data have been obtained on the single-faced board fabri-

cated from each of the hundred and eleven rolls of corrugating medium which

were submitted for evaluation during the month of Marcho     Also included for

purposes of convenient reference are the single-face flat crush and runability

data,   The current machine averages for each test are summarized in Table I for

Machines A through So     A graphical presentation of the current machine caliper

averages on single-faced board is shown in Figure 1, and a similar presenta-

tion of the current machine averages for the caliper difference between con-

secutive flutes is given in Figure 2. The test results obtained on the in-

dividual rolls of medium submitted by each company are given in Tables II

through XX for Machines A through S, respectively


             It may be seen in Figure 1 and Table I that the average caliper

results for the single-faced boards varied from a low value of 19305 points

for Machine K to a high value of 199o4 points for Machines E and R. Likewise,

from the results given in Table I and Figure 2, it may be noted that the

average caliper difference between consecutive flutes ranged from a minimum

of 0.9 points for Machine P to a maximum of 3.6 points for Machine Ao. The

majority of the machines were associated with average caliper differences

of less than 2o5 points     The differences which exceeded three points may be

excessive.
