Feed Dogs
A feed dog is a movable plate which pulls fabric through a sewing machine in discrete steps between stitches. Action A set of feed dogs typically resembles two or three short, thin metal bars, crosscut with diagonal teeth, which move both front to back and up and down in slots in a sewing machine's needle plate: front to back to advance fabric gripped between the dogs and the presser foot toward the needle, and up and down to recess at the end of their stroke, release the fabric, and remain recessed while returning before emerging again to begin a new one. Name A mechanical dog is named to suggest the jaw or teeth of a dog, the animal, clamped on to an object, refusing to let go. This arrangement is called "drop feed" in reference to the way the dogs drop below the needle plate when returning for the next stroke. Allen B. Wilson invented it during the time period 1850 to 1854,The date of 1850 is given by James Paton in his "Sewing Machines" article in the Encyclopædia Brit ...

Sewing Machine
A sewing machine is a machine used to sew fabric and materials together with thread. Sewing machines were invented during the first Industrial Revolution to decrease the amount of manual sewing work performed in clothing companies. Since the invention of the first sewing machine, generally considered to have been the work of Englishman Thomas Saint in 1790, the sewing machine has greatly improved the efficiency and productivity of the clothing industry. Home sewing machines are designed for one person to sew individual items while using a single stitch type at a time. In a modern sewing machine, the process of stitching has been automated so that the fabric easily glides in and out of the machine without the inconvenience of needles, thimbles and other tools used in hand sewing. Early sewing machines were powered by either constantly turning a handle or with a foot-operated treadle mechanism. Electrically-powered machines were later introduced. Industrial sewing machines, by co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dog (engineering)
In engineering, a dog is a tool or part of a tool, such as a pawl, that prevents or imparts movement through physical engagement. It may hold another object in place by blocking it, clamping it, or otherwise obstructing its movement. Or it may couple various parts together so that they move in unison – the primary example of this being a flexible drive to mate two shafts in order to transmit torque. Some devices use dog clutches to lock together two spinning components. In a manual transmission, the dog clutches, or "dogs" lock the selected gear to the shaft it rotates on. Unless the dog is engaged, the gear will simply freewheel on the shaft. This word usage is a metaphor derived from the idea of a dog (animal) biting and holding on, the "dog" name derived from the basic idea of how a dog jaw locks on, by the movement of the jaw, or by the presence of many teeth. In engineering the "dog" device has some special engineering work when making it – it is not a simple part to ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rotary Hook
The rotary hook (aka rotating hook) is a bobbin driver design used in lockstitch sewing machines of the 19th and 20th century and beyond. It triumphed over competing designs because it can run at higher speeds with less vibration. Rotary hooks and oscillating shuttles are the two most common bobbin drivers in use today. Operation The rotary hook continuously rotates in place, hooking the upper thread each time its pointed tip passes the 12 o'clock position. Enough upper thread is pulled from above to pass around the bobbin case, which sits loosely inside the hook frame such that loops of thread can pass completely over it. The excess thread, no longer needed, is then pulled back upward by the sewing machine's take-up arm. This arrangement is mechanically very simple but also introduces a significant limitation. Since the lower bobbin must pass completely through the upper thread, and the upper thread necessary to complete this passage must be completely withdrawn by the take-u ...

Backstitch
Backstitch or ''back stitch'' and its variants ''stem stitch'', ''outline stitch'' and ''split stitch'' are a class of embroidery and sewing stitches in which individual stitches are made backward to the general direction of sewing. In embroidery, these stitches form lines and are most often used to outline shapes and to add fine detail to an embroidered picture. It is also used to embroider lettering. In hand sewing, it is a utility stitch which strongly and permanently attaches two pieces of fabric. The small stitches done back-and-forth makes the back stitch the strongest stitch among the basic stitches. Hence it can be used to sew strong seams by hand, without a sewing machine. How to do it A versatile stitch which is easy to work, backstitch is ideal for following both simple and intricate outlines and as a foundation row for more complex embroidery stitches such as ''herringbone ladder filling stitch''. Although superficially similar to the Holbein stitch, which is comm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
