Description
MF-7500 Series
High-speed, Flat-bed, Top and Bottom Coverstitch Machine (Universal Type)
The MF-7500 Series is a newly developed coverstitch machine provided with lots of mechanisms for improving the seam quality.
It is provided with many different sewing-related mechanisms which contribute to improved seam quality, such as the new feed mechanism, and differential-feed micro-adjustment mechanism. In addition, the machine is provided as standard with a looper thread twining prevention mechanism.
The machine can be used for the hemming process of the sleeves and bottoms of T-shirts and for the covering process for sportswear and knitwear. The front cover is trimmed to allow operators to bring their hands closer near the needle entry area, thereby increasing work efficiency
Thanks to the new feed mechanism, many different types of sewing are achieved.
The feed focus can be adjusted externally. The feed locus is now adjustable in terms of the vertical direction and horizontal direction, thereby improving responsivness to sewing materials.
The Longitudial Position
The longitudial position of the feed is adjustable. As result, uneven material feed and puckering that are likely to occur when sewing products made of elastic materials are reduced. This means that the machine promises improved responsiveness to elastic materials.
Differential-feed micro-adjustment mechanism
It is possible to finely adjust the differential feed amount to a best-suited value for the material to be used. The differential feed ratio is constant even if the stitch length is changed.
Micro-lifter mechanism
Elastic material or delicate material can be sewn with the presser foot kept slightly raised. This effectively helps reduce the degree of slippage, warpage and damage of the material.
The looper thread twining prevention mechanism
In the case of looper thread breakage, the looper thread twining prevention mechanism is activated to trim the looper thread before the thread twines on the looper thread cam. In addition, the looper thread cam, which has been incorporated in the sewing machine, has been changed so that it is mounted outside of the sewing machine.
All of the sewing machines with a thread trimmer are provided with a direct-drive motor.
The direct-drive motor system has been adopted by all of the sewing machines with a thread trimmer. As a result, the sewing machine starts up swiftly and promises increased stop accuracy, thereby demonstrating improved responsiveness. In addition, the machine is no longer provided with a V-belt. This means that the adoption of the direct-drive motor is also effective in the elimination of belt shavings. Power is directly transmitted from the motor to the sewing machine, thereby contributing to reduced power consumption. (This sewing machine reduces power consumption by 29% as compared with the conventional models.)
