The foundation for high yarn quality is established in the blow room. Careful bale opening is a fundamental pillar of this process. Only in this way, a homogenous tuft flow is ensured for optimal downstream processing.

The latest Truetzschler innovation in the blowroom Portal Bale Opener BO-P is designed to allow significantly more bales to be placed side by side and processes them in parallel using two opening rolls. This results in significantly better blending and higher productions of up to 3,000 kg/h, according to the manufacturer.

First customer feedback

The Indian company Polytex was equipped with the first portal bale opener in India prior to ITMA in Barcelona. Within less than one week the entire installation and start-up was completed. By positioning the BO-P with a working width of 2,9 metres and a length of 60 metres close to a wall it was possible to save space.

For the Deputy General Manager K. Sundara Rajan it was important to invest in the currently most secure bale opener on the market: “A comprehensive concept to ensure the safety of the employees is of great significance for the company. The combination of the high working width and the lower overall width was another essential argument for the purchase”. After about seven months of experience with the BO-P the customer highlights also the low maintenance and the quiet operation.

“When the concept of the portal bale opener was presented at Truetzschler for the first time, the benefits for our customers were clear to see. At that time the BO-P was only an idea without any proof from the market and with many technical and technological challenges ahead. Truetzschler had the knowledge, experience and confidence to put this idea into reality. It’s a big joy to see that the BO-P is well received and that it performs the way we promised it to our customers,” said Johannes Bossmann, Design Engineer.

From a bale plucker to the portal bale opener

The Truetzschler blow room was born in the beginning of the 20th century. In 1902 Truetzschler started to expand its product range and began to build cleaning and dust removal systems for cotton processing. The first automatic bale work-off in form of a “bale plucker” was introduced in 1963. Sixteen years later, in 1979, the Blendomat, which worked according to the “bale milling” principle, was created.

Over the years the Blendomat principle has been adopted by all machine builders worldwide. In 2019 Truetzschler presented the next generation at the ITMA in Barcelona.

Better blending from the start

The new and unique portal concept is designed to make the large working width possible in the first place. With a 2,9 m or 3,5 m width and a bale lay-down area of up to 75 m length, the Portal Bale Opener BO-P offers flexible bale placement. Because two opening rolls work in parallel, tufts from 5 to 14 bales are processed simultaneously. This lays the foundation for homogeneous blending in the blow room, the company explains.

Increased opening and higher performance

The two longwork-off rolls have nearly twice as many teeth, newly arranged. This results in a fibre-friendly work-off and a uniform, homogeneous surface appearance. Due to the large working width and the simultaneous use of two opening rolls, small tufts are already produced during the first process in the spinning mill. This is impossible for systems with only one roll and a smaller working width. The new conditions are said to allow productions of up 3.000 kg per hour.
