[3] Gripper
This is an auxiliary device for better solidifying the leno weave of selvage by holding the filled yarn ends (lefthand
ends).
[3.1] Installation Adjustment
(1) [Positional relationship with the temple]
Determine a clearance “a” between the end face
of a temple ring 1 and a gripper holder 2 as 0.5
mm.
(2) [Relative position with the reed]
Install a reed 3 so that a clearance “b” between the
right-hand end of the gripper and the left-hand
end of No. 1 blade of the reed 3 becomes 1 mm.
(3) [Vertical position]
Set the crank angle to 0
°
. Adjust the gripper
holder 2 so as to have a warp held with a yarn
guide spring 4 and the gripper holder 2 be
positioned at the same height as the cloth fell
height C.
(4) [Contact pressure of yarn guide spring]
Adjust the contact pressure of the yarn guide
spring 4 by turning a nut 5 so as to have the warps
arranged on one line with the cloth fell height C
and firmly held.
・
Should a warp be pulled out of the holding as
the reed retreats after the beating, increase the
contact pressure.
・
Fluff will be produced if the contact pressure is
excessive. Decrease the contact pressure.
・
Care should be taken for the yarn guide spring
4 coming off the gripper holder 2 if the contact
pressure is either excessively strong or weak.
