Inspecting Line |
Uncoiling Line
New line is coiled, bound, and wrapped in burlap.
This protective covering should not be removed until
the line is to be used because it protects the line during
storage and prevents tangling. To open, remove the
burlap wrapping and look inside the coil for the end
of the line. This should be at the bottom of the coil.
If it is not, turn the coil over so that the end will be at
the bottom. Pull the end of the line up through the
center of the coil (fig. 4-4). As the line comes up
through the coil, it will unwind in a counterclockwise
direction.
Uncoiling Nylon Line
Do not uncoil new nylon line by pulling the ends
up through the eye of the coil. Avoid coiling nylon in
the same direction all the time, or you could unbalance
the lay.
Making Up Line
After the line has been removed from the
manufacturer’s coil, it may be MADE UP (that is,
prepared for storage or for use) by winding on a reel.
It may also be made up by cooling down, faking down,
or blemishing down.
To COIL DOWN a line simply means to lay it in
circles, roughly one on top of the other (fig. 4-5). Line
should always be coiled in the same direction as the
lay-clockwise for right lay and counterclockwise for
left lay. When a line has been coiled down, one end
is ready to run off. This is the end that went down last
Figure 4-4.—Uncoiling line.
Figure 4-5.—Colling down line after use
and is now on top. If, for some reason, the bottom end
must go out first, you will have to turn your coil over
to free it for running.
Whipping a Line
The term whipping refers to the process of
securing the ends of a line to prevent the strands
from unlaying and the yams from separating or
fraying.
It will not increase the size of the line
enough to prevent the fitting of the blocks or
openings through which it must pass. Whippings
are made with fine twine.
Figure 4-6 shows the steps to follow in applying
a whipping. Make a loop in the end of the twine and
place the loop at the end of the line, as shown in the
figure. Wind the standing part around the line
covering the loop of the whipping. Leave a small loop
uncovered, as shown. Pass the remainder of the
standing end up through the small loop and pull the
dead end of the twine, thus pulling the small loop and
the standing end back towards the end of the line
underneath the whipping. Pull the dead end of the
twine until the loop with the standing end through it
reaches a point midway underneath the whipping.
Trim both ends of the twine closeup against the loops
of the whipping.
Before cutting a line, place two whippings on the
line 1 or 2 inches apart and make the cut between the
whippings, as shown in figure 4-7. This procedure
prevents the ends from untwisting after they are cut.
