Coiling in cans

Index

The sliver must be  coiled in cans for storage and transport. As described in  "Technology of Short-staple Spinning", this is performed cycloidally, with large windings when working with smaller cans and small windings when working with larger cans. Can diameters now lie in the 600 to 1 200 mm range and can heights are between 1 000 and 1 220 mm. If the cans are supplied directly to the rotor spinning machine, they must be smaller because less space is available (better suited as round cans are rectangular cans).

The can diameter in this case is only about 350 to 400 mm. Fig. 118 gives Trützschler data on the capacity of cans with a height of 1 200 mm.

Most manufacturers offer cards with can changers as either standard equipment or an option. These permit efficient operation since they enable the need for attendance by mill personnel to be reduced substantially.
