Up to 1,200 mm diameter, up to 1,500 mm height – these new can dimensions are only available from Trützschler.
The larger the cans, the greater the efficiency of the downstream machine. Greatest economic advantage: 43% longer runtime in the creel results in reduced downtimes on autoleveller draw frame or Superlap. Efficiencies can be increased by 1.5 - 2 %.
43 % more card sliver per can
Compared to a can with 1,000 mm diameter, a can with the new 1,200 mm diameter format holds 43 % more card sliver. The logical consequence is a reduction of downtimes of up to 43 % for the can change. The result is an improved overall card efficiency.
Can transports reduced by 30 %
The full cans must be transported from the card to the breaker draw frame. In a spinning mill with an annual production of 10,000 t this means more than 190,000 transports per year or approx. 24 per hour. With the new can format, only 17 can transports per hour are required.
Less cans at same material buffer
To ensure trouble-free operation, material buffers between the production steps are practical. Thanks to the new can concept, less cans are needed for the same amount of material in the buffer.
Less personnel required
Less can transports and less can changes in the creel reduce personnel requirements or increase personnel efficiency: One person can operate more draw frames/cards.
Reduced sliver piecings improve the quality
Of course, 30 % less can changes in the creel also mean 30 % less sliver piecings and thus 30 % less potential error locations. In our spinning mill example with a production of 10,000 t per year, 58,000 fewer sliver piecing are required on the breaker draw frame.
