Truetzschler has introduced a twin draw frame called the Truetzschler Breaker Draw Frame TD 9T, it has been officially announced.
The twin draw system incorporates two deliveries, but is not based on the traditional double head principle. The advantage of low space requirement has been maintained, while its disadvantage of double head draw frames and poor efficiency has been eliminated, according to a company release.
The twin draw frame TD 9T has two independent production sides. If a standstill occurs on one side, the other side continues producing. This applies to the can changer as well, since when one can is full, it gets changed.
There is no need to wait until the other can is full as well and so there is no coupling efficiency between the two sides.
With this concept, it will be possible to produce different qualities on both sides. In a small air-jet spinning mill, the TD 9T operates on one side as blending draw frame and on the other side as second passage.
The twin draw frame has been designed for the application of jumbo cans with 1,200 mm diameter. This applies to can set-up in the creel and at the delivery side. These cans hold 43% more sliver than conventional 1,000 mm cans. This means less sliver piecings and significantly less can transports.
Both draw frame sides are operated from a platform that is located in the middle. This saves space and reduces the walking distances for operators. The colour touch screen makes operation simple and effective, the release said.
