British inventor creates a brand new sewing system that eliminates the bobbin.
When you record the worlds high inventions the stitching machine isn’t included, it’s lucky if it makes it into the highest 50!
But there are only a few moments in our daily life when we’re not close to something that’s been produced using a sewing machine.
Now a recent patent, developed by a Phuket expat, is set to deliver the stitching machine again into the forefront. Templeton Hancock, a British stitching machine mechanic and former sewing machine demonstrator residing in Rawai, has created a new Everlasting Bobbin Sewing (EBS) System that eliminates the necessity for continually altering thread bobbins.
A bobbin is a spindle or cylinder, with or with out flanges, on which wire, yarn, thread or film is wound. Bobbins are typically present in sewing machines, cameras, and within electronic tools. In non-electrical functions the bobbin is used for tidy storage with out tangles – Wikipedia
“The inception to create the EBS System came to me after a dialog I had with a buyer who voiced her frustration with having to continually change the bobbin. It made me query why no one had come up with a passable resolution to discard it.”
“The EBS System presents big benefits not simply to manufactures however to everybody who often uses a sewing machine; it saves time, improves the quality and end of garments, reduces waste and make the sewing machine more user-friendly and lessens the influence on the setting.”
The first patented stitching machine was in 1790 to an Englishman, Thomas Saint. Over the following 60 years, the machine was modified and improved to something that is nonetheless mechanically recognisable compared to today’s machines.
Since the 1980’s there have been important electronic developments to the stitching machine, but the need for a refillable bobbin has always harkened back to its introduction in 1853. Over the years, there have been many who have tried to unravel this bobbin dilemma. The simple EBS System provides the solution.
So, how does it work?
With present expertise, the needle and upper thread cross down into the machine bed. As the needle attracts back up, the upper thread is left behind, simply slightly, however it is sufficient that a loop is fashioned. Machines are timed so that a rotating hook beneath the machine, spinning off a centrally positioned drive shaft, can catch this loop and cross it over the bobbin and bobbin case to create a locking sew.
The EBS System is different. The drive shaft is moved to one facet and the hook is placed within a bearing which has drive tooth on its circumference. A void is now created throughout the bearing which allows for a thread feed tube to supply infinite quantities of thread to freely pass without interruption from the rotating hook, eliminating the need for a bobbin.
The bobbin holds, on average for #40 weight thread, round 34.3m of thread. In manufacturing this can equate to the bobbin running out on common, every 9/11 minutes. Methods of turn around to get the machine operational once more can differ from 22 seconds to three minutes, slicing into the amount of hourly units produced and likewise growing wastage/seconds clothes for the merchandise in manufacturing when the thread ran out.
Analysis of Operation in manufacturing places aside a mean 20% of Standard Allocated Hours (SAH) for altering the bobbin, changes and employees rest breaks. By eradicating the necessity to refill the bobbin and using the EBS System, manufacturing can be increased by as a lot as 19%.
Realising the issue with the bobbin, many producers have opted for using a series sew as an alternative of a locking thread for seaming. The downside being that the chain stitch makes use of more thread, creates a bulkier seam and isn’t as robust as the lock sew.
By using the EBS System as an alternative of a series sew, a manufacturing unit making denims (for example) could save an average of 8.9m of thread per unit produced (depending on method of manufacture), and on the identical time produce a better quality garment with stronger and less bulky seams. eight.9 metres multiplied by the quantity of units produced each day, week and month, equates to being considerable saving even earlier than you add back within the garments that would often be discarded as wastage/seconds which have now been mostly eliminated.
The EBS System isn’t just limited to clothing. Worldwide , upholstery, luggage and automotive producers are also to learn from the shortage of a bobbin. When the bobbin thread runs out, holes have been made within the material and it takes a short while earlier than the machine operator notices.
The precision of the fit and strength of the material has been compromised and a labour intensive process now begins to reinforce the sew and try to match the holes already created within the materials.
A continuous stream of thread will scale back the quantity of wastage of leather-based and vinyl products in the pursuit of perfection that’s expected and demanded by customers.
The EBS System is not only for industrial use.
The simplicity of the design makes it versatile for use in the domestic market. The EBS System is a reduction to home sewing enthusiasts whose pursuits are within home decor and quilting. No more will they undergo the frustration when the thread runs out in the midst of a project.
The versatility of the EBS System is that it can additionally be used with the current refillable bobbin for those small repairs and quick fixes that would require a wide range of quick lengths of various colored thread.
The EBS System additionally appears to the future. A.I. and automation is making advances into the stitching trade, however these machines nonetheless need to be rigorously monitored as they nonetheless depend on the need for a refillable bobbin. Using the EBS System machines will enable manufactures to run for 24 hours with little or no supervision, with an endless circulate of decrease lockstitch thread.
