ROLLING MED
ROLLING MED is a universal device aimed at satisfying the widest range of both bare and covered elastomer feeding applications. Its versatility allows to fit most of elastomer packages sizes (max width 160 mm, max diameter 168 mm), thus resulting in a unique product in seamless, knitting, hosiery and medical hosiery market.
ROLLING MED is a unique solution on the market, thanks to its capability to combine in a single device the flexibility and user-friendliness of BTSR Constant Tension Feeding Technology with the product top quality resulting from bare elastomeric yarn feeding at constant LFA/speed. Thanks to the BTSR self-adaptive electronic technology, ROLLING MED is infact able to operate at constant tension yarn feeding during yarn "start/stop" working phases (or during strong yarn pattern selections) and to automatically switch to constant LFA / speed feeding during the garment production.
MAIN BENEFITS
Based on derulè yarn reeling-off working concept, ROLLING MED technology allows to eliminate yarn "twisting effect" (flat yarns) and to guarantee the capability to feed elastomeric yarns at constant speed/LFA.
ROLLING MED System features the BTSR Patent Pending "Master-Slave Dual Working Mode" solution (derulé at constant tension / derulé at constant LFA), with possibility of selecting a single (or multiple) device as MASTER and a number of devices as SLAVE associated with the MASTER and reproducing exactly the same MASTER behaviour, thus guaranteeing the absolute stitch matching, preventing yarn plating faults in vanisè process and ensuring Top quality garment production. Combined with ULTRAFEEDER devices (configured as MASTER) installed on the machine for background yarn feeding control, the ROLLING MED (configured as SLAVE) can operate at constant "stretch ratio", thus guaranteeing a fully automatic constant yarn feeding / stretching and Top Quality repeatability.
ROLLING MED is designed to minimize and simplify the operator tasks, thus guaranteeing the achievement of most demanding production efficiency goals and getting TOP Quality Production.
