Abstract

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.
