Abstract (en)
[origin: CA3167494A1] A sewing machine has seam-forming tools, comprising a needle for guiding an upper thread and a looper. The needle is designed as a curved needle which is pivotable about a needle pivot axis. This embodiment is such that a distance of the curved needle from the pivot axis is equal to a radius of a curve of the curved needle about the pivot axis. The looper is designed as a looper which is rotatable about a looper rotational axis and has a lower thread reserve. The looper rotational axis runs parallel to a sewing material support region. The sewing machine can be used to produce a durable seam.
