Abstract: A fabric circle cutter having a cutter base, a pivot pin assembly, and a blade assembly. The cutter base has a flat, smooth bottom surface with a turned up edge. The cutter base also has a raised base section which has a pivot point slide slot. The pivot pin assembly is slidably mounted on the raised base section and slidably mated with the pivot point slide slot which provides for selective positioning of the pivot pin assembly. The blade assembly has a rotary blade with a blade axis which is aligned approximately horizontally with and approximately parallel to the center line of the pivot point slide.

Abstract: A hoop frame unit having a frame support structure, a hoop frame assembly, and a machine carriage assembly. The hoop frame assembly has a front fabric retainer, a rear fabric retainer, a first end retainer, and a second end retainer. Retainer clips mate with retainer seats on each of the retainers to secure fabric zones of quilt cores in place for machine sewing. The machine carriage assembly is supported by a front carriage track and a rear carriage track which are affixed on opposing ends to the frame support structure. The machine carriage assembly incorporates a lateral carriage element for carriage lateral movement, and a pair of longitudinal tracks on the lateral carriage element to provide for machine longitudinal movement.

Abstract: A take-up rail assembly including a fixed idler rail and a longitudinally movable take-up rail. The fixed idler rail is attached to a quilting frame or other sewing frame and the position of the fixed idler rail may be longitudinally and vertically adjustable with respect to the sewing frame. The take-up rail is movably attached to the sewing frame and a take-up rail control mechanism moves the take up rail longitudinally forward and rearward with respect to the fixed idler rail as the sewing machine moves with respect to the sewing frame, thus providing full utilization of the throat length of the sewing machine.

Abstract: A hand-held, rotary fabric cutter having a handle, a blade assembly, a guard assembly, and a light assembly, the blade assembly and the guard assembly being attached to the handle by a blade bolt. The rotary cutter has a rotary blade and a longitudinally and laterally retractable blade guard attached to the handle by the blade bolt, the blade guard having a right guard and a left guard, the right guard and the left guard being pivotally connected by a guard pivot joint. The light assembly has a light element, an electric switch for the light element, a power source, and electrical interconnection. A slide knob simultaneously controls both the guard assembly and the light assembly.

Abstract: A method and apparatus for automated assisted sewing of an oversized, digitized sewing pattern, using a fabric retention mechanism and an automated sewing machine positioning mechanism. The sewing machine positioning mechanism is controlled by an actuator and provides for two dimensional positioning of a sewing machine with respect to the fabric retention mechanism. The oversized sewing pattern is segmented into pattern segments and the pattern segments are sewed sequentially in accordance with a selected order, with the fabric being repositioned after each segment is sewed. Cut points for pattern lines on the border of each pattern segment are matched by start points on the adjacent border of a subsequently sewed, adjacent pattern segment. A pattern program adjusts the pattern lines of each subsequently sewed segment to provide for continuity and alignment of the pattern lines which cross the borders between pattern segments.
