[2] Setting for top beam control
(1) Warp tension (for boarder and ground weavings)
For the Jacquard newCAN specification, individually input tensions for ground and border weavings respectively.
For the other specifications, any setting for ground weaving is not displayed.
Input tension to border, when ground weaving, border ground weaving, borderweaving are set.
(2) Warp tension (for pile weaving)
Input a tension for pile weaving.
For the Jacquard newCAN specification, tensions can be also switched in three steps during pile weaving by tension
switch signals sent from the Jacquard.
(3) Warp tension (Stop)
Input the tension upon loom stop during pile weaving.
NOTE
: Always set it lower than the tension for (Pile).
(4) Beam diameter
Input the top beam diameter.
(5) Tension adjustment (border
→
pile)
This setting corrects the pile yarn let-off amount upon switching weaving from border to pile.
The value should be around 0.4.
If pile defects occur in the 1st to 5th rows after switching to pile weaving, increase the value at intervals of 0.1.
If pile is normally produced at first but pile defects occur in any rows from the 3rd, 4th or 5th, decrease the value at
intervals of 0.1.
(6) Tension adjustment (pile
→
border)
This setting corrects the pile yarn let-off amount upon switching pile
→
border weaving.
Set the value to around 0.4.
When the final pile becomes smaller upon switching into the border weaving, increase the value by 0.1.
Conversely, when the final pile becomes larger, decrease the value by 0.1.
(7) Tention adjustment (run
→
stop)
This setting corrects the pile yarn let-off amount upon loom stop during pile weaving.
The value should be around 0.2.
If the actual tension is constantly higher than the Warp tension (Stop: S) in [2] (3) above, increase the value to
above 0.2.
Conversely, if the tension is constantly lower, decrease the value to below 0.2.
(8) Tention adjustment (run
→
stop)
This setting corrects the pile yarn let-off amount upon loom stop during pile weaving.
The value should be around 0.2.
If the actual tension is constantly higher than the Warp tension (Stop: S) in [2] (3) above, increase the value to
above 0.2.
Conversely, if the tension is constantly lower, decrease the value to below 0.2.
(9) Beam diameter proximity switch error
This is to set whether the loom stops or just issues an alarm when the input of the beam diameter proximity switch
has an error.
Select the alarm for continuous operation when an auxiliary beam diameter proximity switch is not available.
The operation can be continuous with a feature of let-off correction, however, you still need to confirm whether or
not the pile length has an error.
(10) Use / Not use of top beam
Set the top beam as not used for weaving other than towel that does not require the top beam.
