Popular 10 technology trends in sewing machine With the outburst of Industry 4.0, the apparel industry is witnessing the outbreak of innovations in sewing process. These innovations are transitioning the status of apparel manufacturers from being manually relied to tech and digitally focused. Apart from helping in shortening time to market, these trends have taken competition to the next level, which surely will become a survival necessity in the coming future. Big events, such as Texprocess and CISMA, note the new technological developments for apparel industry, disrupting the use of current methods. Team Apparel Online brings to its readers the popular 10 technology trends in sewing that will change the meaning of apparel manufacturing soon. 1 2 Vision sewing Pedal less sewing Decorative stitching requires an accurate fabric feeding to the machine, resulting in precise stitching. It is the operator and his high skill set which manipulate the fabric direction to sew curve and other shapes of patches to be sewed. In the wake of scarcity of high skill set, vision sewing system emerges as an easier way out to obtain flawless decorative stitches. Foot pedals in sewing machine is one area where sewing machine operators spend most of their time to get control while sewing complex stitches and the critical parts. The industrial sewing machines are slowly coming up with the concept of pedal less sewing machine, rendering electronic control of stitches. The system can be integrated with conventional single needle lockstitch, chainstitch machines or electronically programmable pattern sewing machines. The vision sewing system, integrated with an industrial camera look (capture image), processes the captured image at the split of a second and directs mechanical actions by transferring it to the electronic programmable sewing machine. The whole process requires no high skill sets, instead much lesser time. The key benefits of vision system include a consistent sewing speed for multiple patch sewing, automatic sewing of patterns, improved/less handling of the garment or fabric and no operator sewing skills. Brother Vision Sewing System pioneered the system and more players are likely to follow soon. Xi’an Typical recently won Texprocess Innovation Award 2017 for its ‘Vetron Trace’, the first sensor-based technology that offers full control over industrial sewing machines without pedals. The natural working movements of the users are mapped as if by an invisible hand and the data collected is used to begin the new step. Jack is another sewing machine provider that is providing the option of pedal less sewing. In its C4 overlock machine, it offers three operation modes – full intelligent mode, semi-intelligent mode and computerised mode. In full intelligent mode, the machine can work automatically without foot. 3 Automatic bobbin changer A single needle lockstitch operating at high efficiency comes to a sudden halt when the bobbin thread is consumed fully and requires replacement with a new bobbin. Usually carried out manually, the process consumes additional time rendering a plunge in productivity. For uninterrupted sewing, automatic bobbin changers are becoming the need of the hour. Kinoshita has successfully commercialised the use of automatic bobbin changers which stock eight bobbins in the exchange plate and can be integrated with SNLS machines. Embroidery machines, on one hand, are finding greater utility of automatic bobbin changers while the industrial sewing machines are still new to this. Tajima’s Smart Bobbin Changer (SBC) can take only 6 seconds to replace the bobbins for all heads, reducing the downtime of the machine due to bobbin replacement. Another embroidery machine player, Aura Technologies also employs pneumatic bobbin changer in its embroidery machines. Recently Jack has announced auto bobbin changer in its single needle lockstitch model. 46 Apparel Online Bangladesh | October 2018 | www.apparelresources.com 4 5 Real-time monitoring in sewing machines Convertibility in sewing machine The apparel industry is now moving fiercely towards Industry 4.0 and digitalization is one outcome of the same. With discrete gonotrophic locations of apparel units, it becomes almost difficult to control and monitor the status of production. Real-time monitoring is what apparel industry is harnessing the most out of shopfloor. The smart sewing machines are networked over a server which can be viewed over a smartphone or a tablet, from anywhere in the world. The intelligent machine network solution allows to view the status of a whole production line or even a single machine in real time. This real-time status not only helps in the detection of probable obstructions during production but also mentions the scope of productivity improvement. Juki is toying with Intelligent Sewing System (ISS) for quite some time. Digital Process Analysis (DPA) Software from Pegasus also does real time monitoring of sewing line. Brother’s 7300A shows similar capability and very recently Duerkopp Adler entered the fray with Qondac Networks that digitizes the sewing production and gives the user access to remotely control it. Convertibility of bed type, feed type and stitch type is a long pending requirement in sewing machine. Juki and Brother’s double needle lockstitch machine used to offer switching between needle feed to drop feed for long time. Bed types were often custom converted from raised to flat type in case of overlock for long seams. However, now some brands offer submerged bed to raised bed in case of eyelet buttonhole machine. Bar tack to button sewing convertibility is another recent offering by sewing brands. Simply by changing the presser foot, switching the mode of the built-in software, bar tack machine can work as a button sewing machine without changing the parts inside the machine. Both Typical and Siruba (BT290) offer such model.
