ABSTRACT:
The current invention involves a vacuum latchtack throat plate with a vacuum generating system. The throat plate includes a body having a first internal bore beginning at a front edge of the body and extending longitudinally therethrough, and a channel formed in the lower surface of the body. The throat plate further includes a stitch tongue having a front edge and back edge, where the stitch tongue is integrally formed with the body. The stitch tongue has a second internal bore beginning at the back edge and extending longitudinally through the stitch tongue to the body where the channel couples the second internal bore to the first internal bore.
The vacuum generating system includes a source of positive pressure gas, a vacuum generator having an input port, an outlet port and a vacuum port, and a valve for coupling the source to the input port of the vacuum generator. The valve is controllable. The vacuum generating system further includes a conduit coupling the vacuum port of the vacuum generator to the throat plate.
