Optimisation of Needle Penetration Velocity Using the Link Drive Mechanism in a Sewing Machine
sewing machine link drive mechanism optimisation penetration velocity
2009/2/13
Needle movement in a standard lockstitch sewing machine is produced by a slider-crank mechanism. The needle moves in a vertical plane and penetrates the fabric on its way down. Friction between the ne...
A Model of Fabric Transport in a Sewing Machine Using a Feed Dog Covered with a Supple aterial of Increased Friction
sewing machines fabric transport feed mechanism pressure-feed system.
2009/1/20
In this paper, a mathematical model of a feed mechanism which uses a feed dog covered with supple material is presented. The operation of the pressure-feed system has been described using a system of ...
