Automatic quilting machine for specialized quilting of patterns which can be created by utilizing computer graphics in conjunction with a reprogrammable computer

摘要

An automatic quilting machine for use in stitching individual selected patterns into a large fabric such as a bedspread or quilt. The bedspread or quilt is stretched on a large metal frame which is mounted on a table which can be moved in the X-direction, the Y-direction, or any X-Y combination direction. The sewing machine head is mounted on a cross beam which is aligned at the approximate center point of the metal frame on which the fabric is stretched. The needle of the sewing machine head can stitch a pattern into any location in the fabric and the metal frame is moved in any direction relative to the fixed sewing machine head in order to bring the desired stitch location on the fabric into alignment with the sewing machine head. The pattern can be created through reading by a scanner which then converts the pattern into machine readable language which is stored in a process controller. Alternatively, the pattern can be hand drawn on a monitor by graphic systems such as a mouse combined with computer aided design programs which provide graphic menus and through which the drawn pattern can be converted into machine readable language which is then stored in the memory of a process controller. The stored pattern can be subsequently stitched into the fabric through commands from the process controller which direct a remote control apparatus to move the table in the desired direction to create the pattern.
