Vetron’s ‘technology modules’ have made it possible to transform a flatbed machine into a longarm machine and vice versa 6 Modular sewing machines The sewing machines have now moved away from their rigid structure where a sewing machine was designed to perform a particular function, leaving no room for changing of parts to perform a different function. Besides, investment in a new machine is not a feasible option. The innovation in this section brings forth the development of modular sewing machines where the components can be changed and fitted with a new component to adjust to future needs. Such facility no longer requires buying of a new machine, thus increasing the flexibility of the existing sewing machine. The repairing would also require replacing the module with a new one, thus avoiding down times and possible bottlenecks in production. Vetron by Xi’an Typical is the first sewing machine which has grouped all the components of the sewing machine into ‘technology modules’ that can be exchanged at any time. The company has made possible to transform a flatbed machine into a longarm machine and vice versa. 7 8 9 10 Sewing machine settings through mobile phone Digital feed system in sewing machines USB port in sewing machine Voice guided sewing machines The settings on sewing machine have to be adjusted from time to time according to the style of the garment the operator is working upon. These settings should be uniform for each and every sewing machine, but manually changing the settings over each sewing machine is a time-consuming task. Improvement of productivity on a shopfloor is as important as timely delivery of goods to the buyers. Even the slightest of productivity increase notes a significant improvement in efficiency. With the increasing labour costs, the advanced sewing machines are the need of the hour to save the time wasted in non value-added activities. A number of sewing machine manufacturers available aver to improve productivity with the help of their digital feed sewing machines. Each time a new style is injected into a production line, sewing machine settings have to be adjusted on every machine. It increases the changeover time, thus slowing the production. Each time some sewing machine breaks down, the operator informs the line supervisor and the mechanic is then informed to rectify the default. Most of the times, operators are unaware of the reasons that make a machine to stop working. The newest trend is to adjust the settings on sewing machine with the help of an Android tablet in contactless mode or over Wi-Fi or even a mobile phone. The settings, once changed on sewing machine, can then be copied on the complete production line with just one tap on the device. Such a feature enables saving of time and a quick check for uniform settings as well as confirmation of conditions of sewing machines in a sewing line, thereby facilitating set-up changes. Brother S-7300A and Juki DDL-9000C offer such features. Pfaff showed same android tablet monitoring in CISMA 2013. Integrating digital feed in a sewing machine means separating the movement of feed dog from the main shaft which is controlled by a servo motor. A stepper motor is introduced into the machine that independently drives the feed dog. The use of a separate stepper motor allows for precise reverse feeding, design stitching and simultaneous condensed and backtack on the same seam. The sewing machines are now equipped with USB port, so as to facilitate the copying of settings such as stitch length and sewing speed to other sewing machines. Apart from this, easy copying of patterns and upgradation of software can also be done through the USB drive. USB ports are becoming popular amongst sewing operators as these also act as handy mobile charging points or even some USB- driven personal desk fan during summer. There are sewing machines available in the market that come with a voice guide feature where each button on the operation panel has a voice-over that informs the user about technical glitches like machine breakdown, oil leakage/level, etc. Jack offers A5 semi-dry computerised lockstitch machine and C4 fully automatic overlock machine integrated with this voice-over feature. It also informs the operator of any error and explains how the error can be resolved. Some of them are Brother’s S-7300A, Juki DDL-9000C, TYPICAL GC6930A and Duma DM1969M. www.apparelresources.com | October 2018 | Apparel Online Bangladesh 47
