Loom Settings for your Project

Project Setup | Loom Action

A new TempoTreadle system comes with a default settings file for your loom. This settings file has values for the Loom Action configuration. If you have TempoTreadle sensor arrays on more than one loom and share a System Unit and SD card, you will need to verify the settings.

There are currently 4 selections for loom action: Multiple, Single, Table and Table 2. The Loom Action setting can be changed at any time and takes effect immediately.

The most common settings for floor looms are Action Multiple and Position Up; for table looms Action Table and Position Up. For countermarch looms, Action Single is usually used.

Loom Action Multiple

The Multiple Setting accounts for a tie-up on a floor loom where more than one treadle may go down when a treadle is pressed. This is most commonly seen on Jack style looms for certain tie-ups. For example, if treadle 1 is tied to shafts 1,2 and 3 and treadle 2 is tied to shafts 1 and 2, then Treadle 2 will physically go down when treadle 1 is pressed.

In addition, for some weaves, the weaver may press more than one treadle at a time (often called skeleton tie-ups).

If more than one treadle is to be depressed at a time, or more than one treadle may go down automatically, then Loom Action Multiple should be selected.

When this loom action is selected, no error checking occurs until all the treadles are lifted (the shed is closed). At that time the error checking occurs, and if no error the sequence advances. If an error is detected, the error tone is sounded and the pick sequence does not advance.

Loom Action Single

Single Loom action is normally selected for Countermarch looms as they often only have one treadle going down at a time. On Single Action, as soon as a treadle is depressed it is checked against the WIF; the weaver will then hear an error or ok beep while the shed is still open.

If your Jack Loom has a tie-up such that only one treadle goes down at a time, you can use Single Mode and receive your error notifications before you throw an errant pick.

Loom Action Table

Table Loom action waits for all the shafts to be correctly positioned for the current sequence before issuing the “ok” beep and advancing the sequence. This mode does not require a closed shed, and it does not issue error tones. With this mode, the weaver listens for confirmation of the ok beep before placing the pick. A Liftplan (not tie-up) is usually used with this mode.

Loom Action Table 2

Table 2 is the same as Table Loom action, except for only one pick sequence can be displayed at a time due to the number of shafts. If the WIF has more than 8 shafts, there is not room on the screen for the typical WEAV display. In Table 2 mode, you look at the colors Blue means the lever needs to be down, Red means a lever is down that should not be, and Green means the lever is correctly down. See the following link for more information on Table 2 mode.

Position

Position UP means the default state of the magnet is “up” off the sensor. This applies to most looms, and is the default setting.

If Position is Down, the magnets are down (in range) of the sensors as a default and are in the up position if a treadle or lever has been depressed.
