In recent years, card productions have increased rapidly. The can changers, however, have not adapted accordingly. To change a can, the delivery speed of the card must be significantly lowered and then increased again after the change. This reduces efficiency and impacts sliver quality.

The filling head changes position, not the can

T-Move performs can changes at delivery speeds up to 300 m/min. This is only possible due to the controlled movement of a machine element. The cans remain stationary. The sliver, of course, is automatically separated at a precisely defined point. Simultaneously with the movement of the filling head, the full can comes to a stop and the empty can starts to turn. All other can changers require reduced speed during the can change. The relatively unstable cans are not suited for the increased accelerations and decelerations.

Large cans result in more economic efficiency and less sliver piecings

The use of even larger cans at the card is only possible with T-Move. The new Jumbo Cans have a diameter of 1,200 mm and hold 43% more sliver than regular cans with 1,000 mm diameter. This increases economic efficiency and improves quality by eliminating unnecessary sliver piecings in the creel of the downstream draw frame.
