An open-width washing machine is usually a system featuring a vertical path washing with driven cycle of multiple action baths
with a resulting 30/40% water and steam saving.
This operating unit is manufactured in several versions (10-15-30 meters) and can be used for every kind of preparation and finishing treatment. Four different washing actions alternate inside this machine:
1) washing on rising paths;
2) washing on sloping-down paths, carried out by means of spray nozzles, which atomise on both face and back of fabrics, performing a strong penetration action;
3) “vibraplus” effect washing, which removes from the fabric the threadlike elements (fibrils) that do not dissolve in water;
4) extraction washing by means of vessel intermediate squeezing.
The longitudinal tension of the fabric remains perfectly unchanged on the whole path; it can be adjusted between 5 and 20 kg by means of upper cylinders equipped with self-adjusting control system which generates a sliding motion crease-and-fold proof also on extremely delicate fabrics. Plush fibrils are removed from the vessel with no need for brushes or liquor dilutions.
Another type of machine divides the washing process into single steps, which are systematically repeated. In this way the whole
process can be not only constantly monitored but also accurately calculated.
