Special model of differential lockstitch sewing machine

This paper will analyze the application of the special type of differential lockstitch sewing machine.

Like other types of sewing machines, differential sewing machines are based on platform lock-type machines, with subdivisions of upper differential, lower differential, upper and lower differential, and sectional differential. In order to meet the diverse demands of clothing fabrics, processes, and styles, and to improve the production efficiency and quality of clothing, many special models have been derived from the differential sewing machine. Let's take a look at the applications of several major models:

Differential feeding cylinder computerized lockstitch sewing machine 

The demand for cylinder models comes from applications with a small space range. As we all know, the cylindrical sewing processes with small circumferences such as cuff, foot, etc. are very difficult to operate on platform machines and have low production efficiency. If the rubber is added, sewing skills will be more demanding and sewing will be more difficult, which is undoubtedly a big problem for the apparel industry which is already facing difficulties in recruiting and high labor costs.

The differential feeding and barrel structure of the barrel differential lockstitch sewing machine are specially designed and developed for the above problems. When the cylindrical differential flat bed sewing machine is used to do the cylindrical processes such as trouser legs, cuffs, and sleeve bodies, the feeding, and cleaning of fabrics will become very easy, the production efficiency will be higher, and the product quality will be more stable.

Differential feeding and package cutting integrated (side cutting) computerized lockstitch sewing machine 

At present, in garment processing, the application of a computer cutter has been very common. its significant advantage of the cutter is that the sewing and trimming can be completed at the same time, with the switching function of selective cutting and noncutting, and the models with synchronous cutting and asynchronous cutting can be selected to apply to the sewing processes such as turning, arc and straight edges. the biggest performance feature of the differential cutter head compared with the conventional cutter head is that it is equipped with a feeding presser foot, so the presser foot structure has more functions to deal with the twisting, pleating, and other problems that are easy to occur when sewing elastic fabrics, thinner and more slippery fabrics, throwing materials, etc. with the conventional cutter head. At the same time, the differential cutter can also be equipped with feed pressers in the form of forwarding feed, backward pull, and side feed according to the characteristics of the cutter and needle positions of different trimming widths to achieve the best sewing effect.

Differential feeding chain computerized lockstitch sewing machine 

Chain computerized lockstitch sewing machine is a common model in garment processing. There are single needles, double needles, three needles, parallel needles, front and back needles, and other different styles. Now, on the differential chain model, the chain sewing machine with cutter function, the model integrating chain differential and cutter (or bag cutting), and the chain differential belt cutter model with its own mop wheel are further derived, which can meet the diverse needs of garment factories.
