ABSTRACT:
The disclosure is directed to improvements in automatic mechanisms for feeding properly oriented buttons to the sewing station of a sewing machine, in preparation for sewing on a garment. The system utilizes a highly simplified pneumatic actuating system for both feeding and orienting the buttons. The system of the invention is arranged to accommodate a multiplicity of mechanical operations involved in button feeding and orienting, utilizing a simple arrangement of two pneumatic actuators, which are energized in timed sequence by pulses of air derived from operation of the sewing machine. In one of its most advantageous forms, the system of the invention derives the necessary timed energizing pulses of air from control air cylinders which form part of the basic sewing machine mechanism itself. Thus, adaptation of a conventional industrial sewing machine to incorporate the button feeding and orienting system may be accomplished in a highly simplified and economical manner.
