Abstract: A low-cost sewing machine capable of achieving a desired balance between needle thread consumption and bobbin thread consumption is described. A memory section stores needle thread requirement data having precorrected needle thread requirement and postcorrected needle thread requirement. In a torque control zone, rotating force is imparted to a turning arm so as to impart a tension on the needle thread according to a torque value, while closing an upstream grip section main body and while opening a downstream grip section main body. In a first position control zone, the needle thread is drawn according to the postcorrected needle thread requirement, while opening the upstream grip section main body and while closing the downstream grip section. In a second position control zone, the turning arm is returned to an initial position, while closing the upstream grip section main body and while opening the downstream grip section main body.

Abstract: A sewing device includes a material wrapped around a spool (the spool rotating around an axis), and a needle with a hole through which the material passes. A material feeding mechanism moves the needle and feeds the material in a feeding direction, thereby unraveling the material from the spool and stitching the material into a workpiece. A controller controls the material feeding mechanism to move the needle to a first rest position above a top surface of the workpiece. The first rest position is determined by the following formula: PR1=PW1+AT; wherein PR1 is the first rest position; PW1 is a first position of the top surface of the workpiece; and AT is an amount of material to be used in forming a second stitch in the workpiece after forming a first stitch in the workpiece.

The backing material is indexed forwardly along its path of travel through the tufting machine by at least the stitch length for each stitch in a stitch cycle of the programmed pattern. At a desired point in the stitch cycle, the backing material can be indexed forwardly by a greater distance approximately equal to the program stitch length and a calculated jump distance to achieve a desired pattern effect.

Abstract: A feeder movement compensation algorithm for use within a processor controlled sewing machine. The sewing machine configured with a reciprocating needle and thread, and including a stitch plate upon which fabric to be sewn is positioned beneath the needle and thread. The machine also includes a feeder mechanism driving a feed dog thru a movement. The feed dog movement pushes the fabric along the stitch plate and the reciprocating needle and thread form stitches in the fabric. During the stitch cycle, the feed dog movement completes at least one feeder stroke. The feeder stroke includes a portion of the feed dog extending above the stitch plate and moving along the direction of feed. The feeder stroke thus pushes the fabric along the stitch plate. The compensation algorithm calculates a theoretical feeder stroke length based upon a desired stitch.
