摘要:
Dans le cas des transporteurs supérieurs connus selon la demande principale, un système de guidage avec un quadrilatère articulé relié au transporteur supérieur est prévu pour réduire la dimension des pièces en mouvement dudit transporteur dans sa phase d'abaissement. La commande coulissante s'applique également sur le bras pivotant du quadrilatère relié au transporteur supérieur. Afin de corriger la position de l'axe du mouvement elliptique d'élévation/coulissement du transporteur supérieur (6), le guide de raccordement (58) entre le système de guidage (L2) de la commande coulissante et le système de guidage (L1) de la commande d'élévation est articulé directement à la bielle (28) du quadrilatère articulé (19, 18, 28, 29, 32) entre les deux points d'articulation de la bielle (28).
摘要:
Presser device couplable with a sewing machine (10) having a control system and comprising a head (14) and a base (12) on which an article (50) to be sewn rests. The presser device comprises a presser bar (24) couplable with the head (14), and a presser foot (26), hinged through a pivot (28) on said presser bar (24) so as to vary the inclination of the presser foot (26) in respect to the presser bar (24). The presser foot (26) is fit to push the article (50) in order to maintain said article under pressure on the base (12) even if the thickness of the article (50) varies.
摘要:
In a sewing machine (1), a length in a reference direction of a stitch portion is acquired. An image is captured of at least one marker, and image data are generated. An amount of movement of the at least one marker is computed, based on the image data. A revolution speed of a sewing machine motor is set to not greater than a specified value in a case where it is determined, based on the amount of movement that has been computed, that sewing is being performed in a specified range. In a case where it is determined that the length of the stitch portion that has been sewn in the reference direction is not less than the length that was acquired, the sewing of the stitch portion is terminated.

A presser foot (1) for a sewing machine includes a main body (20) rotatably attached to a presser holder (2) via a pivot shaft (4) and having a needle receiving hole (33), and a restriction member (40) rotatbly attached to the main body (20), wherein the restriction member (40) includes a restriction portion (50), which protrudes downward from a bottom face (21) of the main body (20) to press a work material to thereby restrict a movement of the work material when a stepped portion (10) of the work material comes in contact with the presser foot (1).
摘要:
Bei der Obertransportvorrichtung bewegt sich der Obertransportfuss (15) in einem vertikal verlaufenden Schlitz (27) im Arm (17), mit welchem der Obertransportfuss (15) angetrieben wird. Diese Anordnung ermöglicht es, den Obertransportfuss (15) in der Ruhestellung nach oben zu verschieben, so dass an der Drückerstange (11) Zusatzgeräte befestigt werden können.
摘要:
A sewing machine foot has a foot mounting part (44) secured to a pressing bar (14), a pressing part (46) for pressing an article to be sewed when a needle (12) pierces the article, a swing arm (47) having an element guide groove (42) for guiding an element row (9) of a slide fastener (8) inserted in the groove, supported on the foot mounting part (44) so as to be swingable relative to the foot mounting part (44), and swinging in a vertical plane in parallel with a sewing line (28) during sewing, and biasing means (52) disposed between the foot mounting part (44) and the swing arm (47) and biasing the swing arm (47) relative to the foot mounting part (44) toward the article to be sewed. The construction enables the element row (9) of the slide fastener (8) to be guided both when the needle (12) pierces the article and when the needle forms a seam, and as a result, thick fabric (6) and a hidden slide fastener (8) which are difficult to sew to each other can be accurately positioned and sewn.
