Abstract
A thread tension apparatus and method consists of a thread cone holder configured to hold thread where the thread cone holder is connected to a motor. A thread guide is provided where the thread guide includes a thread channel such that the thread guide directs thread to a machine where the machine draws thread in first direction. A motor controller is connected with the motor, where the motor controller operates the motor to turn the thread cone holder such that thread is drawn in a second direction opposite from the machine first direction such that tension is applied to the thread as thread is drawn to the machine.
Claims20
A thread tension apparatus comprising:
- (a) a thread cone holder configured to hold thread wherein the thread cone holder is connected to a motor;
- (b) a thread guide wherein the thread guide includes a thread channel such that the thread guide directs the thread to a machine wherein the machine draws the thread in a first direction and wherein the thread channel includes a vertical channel and a horizontal channel and wherein the thread channel moves up and down within the threat guide in response to where the thread is removed from the thread cone holder;
- and
- (c) a motor controller connected with the motor, wherein the motor controller operates the motor to turn the thread cone holder such that the thread is drawn in a second direction opposite from the machine first direction such that tension is applied to the thread as the thread is drawn to the machine.
A sewing machine thread tension apparatus comprising:
- (a) a thread cone holder configured to hold thread connected to a motor;
- (b) a thread guide wherein the thread guide includes a thread channel such that the thread guide directs the thread to a sewing machine wherein the sewing machine draws the thread in a first direction and wherein the thread channel includes a vertical channel and a horizontal channel and wherein the thread channel moves up and down within the thread guide in response to where the thread is removed from the thread cone holder;
- and
- (c) a motor controller connected with the motor, wherein the motor controller operates the motor to turn the thread cone holder such that the thread is drawn in a second direction opposite from the sewing machine first direction such that tension is applied to the thread as the thread is drawn to the sewing machine and wherein the motor controller operates the motor such that tension on the thread is increased or decreased.
A sewing machine thread tension method comprising:
- (a) providing a thread cone holder configured to hold thread wherein the thread cone holder is connected to a motor;
- a thread guide wherein the thread guide includes a thread channel into which the thread enters and from which the thread exits such that the thread is aligned with the thread channel as it exits the thread guide and wherein the thread channel moves up and down within the thread guide in response to where the thread is removed from the thread cone holder such that the thread guide directs the thread to a sewing machine wherein the sewing machine draws the thread in a first direction;
- a thread gate wherein the thread gate includes a pair of horizontal contacts between which the thread from said thread cone holder is directed and a pair of vertical contacts between which the thread is directed in an “S” pattern;
- and a motor controller connected with the motor, wherein the motor controller operates the motor to turn the thread cone holder such that the thread is drawn in a second direction opposite from the sewing machine first direction such that tension is applied to the thread as the thread is drawn to the sewing machine;
- and
- (b) connecting the thread from the thread cone holder to the thread guide in the thread channel.
