Abstract (en)
[origin: EP0046660A2] A sewing machine comprising a needle bar (14) and a presser foot (10). The presser foot (10) is mounted for heightwise reciprocating movement on a stationary point (36) and is urged upwardly by a spring (42). Biasing means (54, 60) is operable to move the presser foot (10) downwards against the action of the spring (42). The biasing means comprises a spring (60) connected to the presser foot (10). Engaging means (64) mounted on the needle bar (14) engages the spring (60) of the biasing means at a predetermined point in the downward travel of the needle bar (14) so as to cause downward movement of the presser foot (10) until the workpiece is contacted.
