Trimming control

Few Schiffli machines have an automatic thread trim mechanism. Long stitches are usually trimmed manually. During production, connecting threads hang loosely over the fabric. Also when changing colors (RCC machines only), the thread of the previous color remains connected between the fabric and the previous needle. Digitizers must anticipate where the threads will be to avoid overstitching them. Typically tacking is used to lock threads above and to the side of the current point. Schiffli designers frequently avoid the need for trimming by designing fancy connecting lines between main stitched areas.

Note: In ES Schiffli, objects need to be connected by manually digitized travel stitches or manual trims of long stitches with tacking. Automatic connectors do not provide the type of object-to-object connection normally used in Schiffli designs.

ES Schiffli provides an explicit Trim function. This has two main uses – for trimming threads on Schiffli machines equipped with trimmers, and for viewing TrueView™ samples of the final embroidery.
