Abstract
A device for loading a garment for a sewing machine having a first device for moving the garment toward the sewing machine, a second device downstream of the first moving device for moving the garments towards the sewing machine, and a device for changing the speed of the first and second moving devices relative to each other to change the distance between adjacent moving garments according to programmed distance values.
Claims13
A device for loading workpieces for a sewing machine, comprising:
- first means for moving the workpieces towards the sewing machine;
- second means downstream of the first moving means and upstream of the sewing machine for moving the workpieces toward the sewing machine;
- and
- means for actively changing the speed of the first and second moving means relative to each other to change the distance between adjacent moving workpieces according to programmed distance values.
A device for loading workpieces for a sewing machine, comprising:
- a first conveyor for moving the workpieces toward the sewing machine;
- a second conveyor downstream of the first conveyor and upstream of the sewing machine;
- means for sensing the trailing edge of a first moving workpiece and a leading edge of a subsequent second moving workpiece;
- and
- means, responsive to the sensing means, for actively changing the speed of the first and second conveyors relative to each other to modify a distance between the first and second workpieces.
A device for loading workpieces for a sewing machine, comprising:
- a first conveyor for moving the workpieces toward the sewing machine;
- a second conveyor downstream of the first conveyor and upstream of the sewing machine;
- a sensor for detecting the positions of the workpieces;
- and
- a controller, responsive to the sensor, for actively changing the speed of the first and second conveyors relative to each other to change a distance between adjacent moving workpieces according to programmed distance values.
A device for loading workpieces for a sewing machine, comprising:
- means for moving the workpieces toward the sewing machine;
- means for sensing the trailing edge of a first moving workpiece and a leading edge of a subsequent second moving workpiece;
- means for actively changing the speed of the moving means to modify a distance between the first and second workpieces;
- and
- means responsive to the sensing means for measuring the distance between the trailing and leading edges of the first and second moving workpieces, and in which the changing means is responsive to the measuring means.
