The longarm sewing machine frame typically ranges in length from 10 to 14 feet (3.05 to 4.27 metres), and the head is industrial length, 19 to 30 inches (48.26 to 76.20 centimetres). Quilting using a longarm machine can take significantly less time than quilting by hand or more traditional machine quilting methods. This time saving is a large ...
Optical encoders are the most accurate of the standard styles of encoders, and the most commonly used in industrial automation applications. When specifying an optical encoder, it's important that the encoder have extra protection built in to prevent contamination from dust, vibration and other conditions common to industrial environments.
Quilting is the process of joining a minimum of three layers of fabric together either through stitching manually using a needle and thread, or mechanically with a sewing machine or specialised longarm quilting system. An array of stitches is passed through all layers of the fabric to create a three-dimensional padded surface.
A rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the angular position or motion of a shaft or axle to analog or digital output signals. [1] There are two main types of rotary encoder: absolute and incremental. The output of an absolute encoder indicates the current shaft position, making it an angle ...
In machine-shop terminology, the complete digital read-out system (consisting of a computer, axis-position encoders, and a numeric display) is referred to by the acronym DRO. Such a system is commonly fitted to machines in today's shops, especially for metal working — lathes, cylindrical grinders, milling machines, surface grinders, boring ...
Many incremental encoders have an additional output signal, typically designated index [2] or Z, [3] which indicates the encoder is located at a particular reference position. Also, some encoders provide a status output (typically designated alarm) [4] that indicates internal fault conditions such as a bearing failure or sensor malfunction.
For heirloom machine quilting, the operator uses advanced free-motion techniques. The scale of the work is refined, using smaller threads and needles that allow the use of detailed and complex patterns. Quilts with heirloom machine quilting usually include background quilting which fills the negative space around the designs with dense stitching.
Georgia Bonesteel is a quilting judge, author and host of the show. She has been the president of the International Quilt Association, which is involved in the history and art of quilting worldwide. [6] Bonesteel is credited with having invented lap quilting while teaching a class at Blue Ridge Community College in North Carolina. [2]
