A spool-less bobbin apparatus for forming a stitch comprising a needle assembly for an upper thread;
- a looping assembly for the upper thread;
- and an application assembly for depositing a lower thread material onto a stitching surface.
A method for forming a stitch comprising passing an upper thread from a first side to a second side of a stitching surface;
- forming a loop of the upper thread on the second side of the stitching surface;
- depositing a lower thread material on the second side of the stitching surface;
- and closing the loop of upper thread around the lower thread material by passing the upper thread from the second side to the first side of the stitching surface.
An application assembly to deposit a continuous supply of lower thread material to a stitching machine comprising a drive mechanism, a container sized and dimensioned such that said lower thread is pushed through the container by the drive mechanism, and a mechanism to move the container towards and away from a stitching surface.
