M5. Pile Let-Off
Features of Towel Loom Pile Let-Off Mechanism
(1) Can control pile warps with tension.
(2) Can separately set the tension for the pile weave and plain weave.
This prevents the pile yarns from floating in the plain weave.
(3) Changes tension for the pile or plain weave within a fraction of time. This largely prevents tight pile from occurring
at a portion where tension changed or pile yarn from floating in the plain weave.
[1] Pile Let-off Mechanism
(1) A pile easing roller 3 follows the piling motion and
thusprevents the fluctuation of tension caused by the
piling motion.
(2) A let-off controller L rotates the beam by obtaining
information from the loom main control M and a
load cell 4.
It feeds a tension value, etc. of the load cell 4 to the
loom main control M.
(3) A spring mechanism is designed to sharply change
the spring constant according to the pile or plain
weaving.
1
．
Pile tenser plate 1 has a spring constant that is
suitable for pile weaving.
2
．
Because pile tenser plate 1 overlaps with guide
plate 2 at plain weaving such as border weaving,
a spring constant becomes higher to cope with
the high tension.
