A stitching machine may include a needle apparatus, a sewing thread spool receiving device, and a bobbin thread spool receiving device. The stitching machine may further include a bobbin thread tensioner configured to receive bobbin thread from the bobbin thread spool receiving device. The bobbin thread tensioner may be further configured to supply the bobbin thread to the needle apparatus. The bobbin thread spool receiving device is configured to receive a bobbin spool holding approximately 700 meters or more of bobbin thread. The bobbin thread spool receiving device may be located above a stitching location of the stitching machine. The stitching machine may provide improved access to a bobbin spool, enhanced manufacturing efficiency, and enhanced manufacturing flexibility. |
