4.11 Roller top feed (optional)
In addition to the bottom feed, a roller top feed is optionally
available. The top feed can be set independently of the bottom
feed and can thus be adjusted individually to the feed behavior of
the relevant sewing material.
Information
When sewing the stitch condensing at the start and end of the
seam, the roller top feed is automatically adjusted to the shortened
bottom feed.
