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.

A mechanical metering attachment for sewing ribbon such as elastic or woven lace and woven elastic to men's and ladies' undergarments. The attachment can be used on a variety of commercially available industrial sewing machines and is driven by an available and appropriately located oscillating shaft that receives its drive from the main rotary shaft of the sewing machine. The attachment is driven through a one-way clutch that receives its input from the oscillating drive shaft. The feed rate of the ribbon or elastic woven lace can be adjusted by adjusting the point of connection of a connecting rod to a slotted lever which is part of the drive. The attachment includes a driven roll and a pressure roll. The pressure roll is biased into engagement with the pressure roll, and the pressure on the pressure roll can be adjusted to accommodate for the thickness of the ribbon being metered.
