A sewing machine for sewing large work pieces such as sails or tarps has a sewing bed with a large trough, the axis of which is perpendicular to the axis of the sewing head support arm. Fabric is held within the trough either by being folded, bunched or rolled with fabric being either fed into the trough as stitching progresses or is drawn out of the trough during stitching. The fabric may be rolled bunched or folded within the trough. The trough may be selectively covered with a removable cover plate to provide an entirely flat sewing bed for sewing of smaller pieces of fabric.

Why it's free to use
- Filed February 15, 2000 and granted February 6, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 15, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 15, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
