Process and means to optimize utilisation of drums of raising machines and the like.

摘要

An optimal utilization of raising working drums of raising machines and the like may be obtained when the fabric to be raised is put in touch of the raising drum (1) along an arch inferior to 290 degrees and particularly along an arch inferior to 180 degrees. In particular an utilization only of less than 180 degrees of the drum allows more than one raising working step, on the same raising machine and/or drum, which may be applied on different lengths of the same fabric (2) or different fabrics or both sides of the same fabric reversing the same with a fabric turnover device between first and second contact With the arrangement according to the present invention it is possible even with only two series connected raising machines to comprise continuous raising working providing in a single passage through the raising machine a fabric raised on both sides.
