Sewing machine fabric alignment - has working surface where mechanisms give X and Y positions to supply number of work-stations

The appts. to align and position fabric workpieces, for a sewing machine, has a mechanism to move the fabric along the X-co-ordinate axis along a path to a given X-co-ordinate position on a working surface, while a further mechanism positions the fabric at a given Y-co-ordinate position.

Summary:The appts. to align and position fabric workpieces, for a sewing machine, has a mechanism to move the fabric along the X-co-ordinate axis along a path to a given X-co-ordinate position on a working surface, while a further mechanism positions the fabric at a given Y-co-ordinate position. A stationary alignment unit is in the path of the two alignment mechanisms, acting with them to give a simultaneous alignment of the fabric in the X and Y directions. Two sensors, one each at the X and Y position, are fixed in place. A further sensor registers the presence of the fabric on the working surface. The X and Y sensors and/or the fabric sensor are linked to a control. ADVANTAGE - The appts. gives a rapid and accurate alignment and positioning of the fabric, before it is passed to the sewing machine for stitching.
