Development of a Sewing Machine for Burley Tobacco Leaves (Part 1)

Production of a sewing machine for sewing leaves to garland rope

Abstract

A new sewing machine which is suitable for harvested burley tobacco was produced as an experiment with the purpose of saving the tying work. This machine consists of conveyor and a sewing part. The conveyer moves feed intermittently 30mm each time. It sews the leaves arranged on the conveyor at a fixed interval and garland rope to hang together. It is operated by two or three workers. The working hours for sewing operation were 1.3 to 2.1 minutes per rope, 56 to 73% of the time could be shortened toward conventional tying machine. Other good results achieved by this sewing machine included a better curing management and a more efficient work of removing leaves from the rope.
