MECCANISMO TRASCINATORE CON TRASMISSIONE A CINGHIA |
摘要 |
A workpiece puller mechanism for a sewing machine including a carrier including a feed shaft mounted thereon that supports a feed roller. The periphery of the feed roller is biased downwardly into engagement with the upper surface of the workpiece while the lower surface is engaged by the feed dogs. A puller housing is mounted on the sewing machine having a puller shaft rotatably mounted for rotation therein. Rotation of the puller shaft is imparted by a timing belt that overlies sprockets on the sewing machine main drive shaft and the puller shaft. The puller shaft carries a crank head that is connected by a connecting bar assembly to the input member of a one way clutch assembly. The one way clutch assembly provides drive in one direction only to the drive shaft for the feed roller. |
