ABSTRACT:
A tying machine for tying an article, such as an open part of a bag, includes an operating member connected to a drive shaft which in turn is connected to a link mechanism. A rack member is connected pivotally to the link mechanism and engages a single-direction gear which drives a rotary shaft and a cam member. The cam member actuates a wire bending unit, a wire cutting unit, and a wire twisting unit. A returning spring is associated with the drive shaft. The operations of the link mechanism and the rack member may be reversed by turning the operating member to rectify malfunctions.
