Combine / Interleave Weft

Combine and Interleave weft is a powerful tool that allows the merging of the treadling for two wefts. The merged wefts can be interleaved or overlayed, and optionally shifted when doing the merge.

The screenshot below shows a draft with the panel for the Combine Weft selected. The combine weft function is in the Weft Group on the Design Menu.

The panel, a s shown beside a draft below, starts with a Combine From selection. It is necessary to have at least two drafts open in TempoWeave to use the Combine Weft. The draft that has "focus" is the one that will be modified, however the draft that will have the weft sequence to be interleaved or overlayed must be open in TempoWeave and selected in the "Combine FROM" box.

If you aren't familiar with working and switching between multiple open drafts, a very simple way is to click the little "eye" icon in the upper right area of the TempoWeave screen:

If you have a large screen, you may prefer to keep the both the Current and From draft visible on the screen at the same time by using the Tile Function on the Window menu. For more on managing multiple open drafts, see this video Working with Multiple Design Windows

If you are combining the draft with itself, you can either save a second copy and open it as the "from" file, or simply open the same draft again so that it is open and available to select in a second window as the "from" draft; be careful not to be confused when saving so you don't overwrite your transformed draft.

Sample of a Draft with the Combine Weft Panel Open

• Combine FROM: selected window for the from weft sequence.

• Combine Type: Interleave - combine, but add a separate weft pick; Overlay - combine the changes on the pick in the To draft, do not add a separate weft pick.

• Starting Thread: Start the combination of the wefts at pick 1 in the TO draft. If left 0, it will start at pick 1.

• Shift Right: If a value is entered for the shift, move the "from" treadle, or shaft if working in a lift plan, to the right by the specified value. If shifting beyond the last available treadle (or shaft for lift plan), be sure to uncheck Wrap to add treadles or shafts to accommodate the new value.

• Ratio X:1: The ratio allows bringing the from weft picks in and interleaving or overlaying on something other than a 1:1 ratio. For example if 2 is entered in this field and performing and the combine type is Interleave, every other weft pick in the draft TO draft will have a pick from the FROM draft inserted; likewise if the combine type is overlay, every other weft pick will have a pick from the FROM draft used for the overlay. Note that the FROM draft always uses each pick, it is not possible to use a ratio of anything but "1" for the FROM draft.

• Wrap: When using a Shift Right, the checked Wrap box will will cause a shaft back to treadle/shaft 1 after the highest treadle/shaft is is reached. When Wrap is not checked, additional shafts/treadles will be added. The Tie-up will not be changed for added treadles, and must be changed manually.

• Repeat Through End: If the number of weft picks in the From draft are less than needed to complete the combine/overlay throughout the entire TO draft, checking this box will have the From draft cycle back to pick 1 and continue the combination through the end.

• Interleave Color: If checked, the color in the from draft will be used when performing the combine or overlay.

• Interleave Thickness: If checked, the thickness value in the from draft will be used with the combined weft.

Undo / Apply / Accept

Either the Undo or Apply button will be available (one is always "greyed out"). After applying a change, the Undo button will back out the change and allow the Apply button to be available for another combination. To keep the changes, click Accept. Clicking Accept does not save the draft.
