  • Patent number: 4236472
    Abstract: A sewing machine installation for sewing shirt front box hems and having a first underlying belt conveyor for individually conveying shirt front material blanks longitudinally forwardly along a lower main support table through a shirt front edge folder and a second overlying belt conveyor for individually conveying separate box hem material blanks with a liner tape longitudinally forwardly along an upper auxiliary table section through a box hem edge folder and into superimposed preassembled association with the prefolded shirt front blanks; the overlying and underlying conveyors thereafter cooperating for conveying the preassembled shirt front box hems longitudinally forwardly along the main support table through sewing and shearing stations for sewing the preassembled shirt front box hems and shearing excess material from the leading and trailing edges thereof.

  • Patent number: 4154177
    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.
