Abstract
An independent thread tension apparatus and method has a thread support where the thread support releasably retains thread. A motor is connected with the thread support and a controller is connected with the motor such that the controller operates to move the thread support in a first direction as thread is pulled off the thread support in a second direction opposite to the first direction such that a selected tension is added to the thread.
Claims20
An independent thread tension apparatus comprising:
- a. a thread support wherein the thread support releasably retains thread and wherein the thread support is removably attached to a sewing machine;
- b. a motor connected with the thread support;
- and
- c. a controller connected with the motor such that the controller operates to move the thread support in a first direction as thread is pulled off the thread support in a second direction opposite to said first direction such that a selected tension is added to the thread.

An independent thread tension apparatus comprising:
- a. a thread support connected with a swing machine;
- b. a dread spool wherein the thread spool is configured to hold thread and wherein the thread spool is configured to releasably connect with said dread support;
- c. a motor connected with the thread support;
- d. a controller connected with the motor such that the controller operates to move the thread support in a first direction as thread is pulled off the thread spool in a second direction opposite to said first direction, such that a selected tension is added to the thread;
- and
- c. a thread break detector connected with the sewing machine and configured to stop the operation of the sewing machine upon detection of thread breaking.
3 more elements
An independent thread tension method consisting of:
- a. providing a thread support wherein the thread support releasably retains a thread spool wherein said thread spool holds thread;
- a motor connected with the thread support and a controller connected with the motor such that the controller operates to move the thread support in a first direction as thread is pulled off the thread spool in a second direction opposite to said first direction such that a selected tension is added to the thread and a thread break detector connected with the sewing machine and configured to stop the operation of the sewing machine upon detection of the thread breaking;
- and
- b. connecting said thread to a sewing machine.

An independent thread tension apparatus comprising:
- a. a thread support wherein the thread support releasably retains thread;
- b. a motor connected with the thread support;
- c. a controller connected with the motor such that the controller operates to move the thread support in a first direction as thread is pulled off the thread support in a second direction opposite to said first direction such that a selected tension is added to the thread;
- d. a thread spool wherein the thread spool is configured to hold thread and wherein the thread spool is configured to releasably connect with said thread support;
- e. wherein the thread pool and thread support include a rotation resistance device such that, when connected, thread spool rotation in one direction as thread is removed is resisted by connection of said resistance device with the thread support;
- and
- f. wherein the rotation resistance device includes a thread spool slot and a thread support peg wherein the thread support peg is configured to connect with the thread spool slot such that said thread spool is held in place on said thread support.

An independent thread tension apparatus comprising:
- a. a thread support wherein the thread support releasably retains thread;
- b. a motor connected with the thread support;
- and
- c. a controller connected with the motor such that the controller operates to move the thread support in a first direction as thread is pulled off the thread support in a second direction opposite to said first direction such that a selected tension is added to the thread;
- d. wherein the thread is connected with a sewing machine such that operation of the sewing machine pulls thread from the thread support;
- and
- e. a thread break detector connected with the sewing machine and configured to stop the operation of the sewing machine upon detection of thread breaking wherein the thread break detector is connected with the motor, the thread break detector configured to stop the operation of the sewing machine upon detection of motor misfunction.
