Abstract
The present invention relates to a process and equipment (1) for creating prints on non-woven-fabric and, particularly, relates to a process and to equipment (1) which allows the creation of colour prints on non-woven fabrics at high speed whilst at the same time maintaining optimal print quality on wet or dry product, either in-line with production or off-line. The NWF may be printed over only a small percentage with respect to its surface (2-3%) up to a coverage of 100% of its surface, depending on the use of the NWF itself, i.e.: personal hygiene, domestic hygiene, matting, non-woven fabric for clothing, table-cloths, handkerchiefs, curtains (furnishings), bags, containers for items.
Claims34
Equipment for printing on non-woven-fabric, comprising a support driven such as to transport a sheet of non-woven-fabric, at least one driven printing body in order to carry out the printing and a control and command unit operatively connected with each of said support and at least one printing body such as to detect electrical signals originating from said support and at least one printing body, turn said signals into numerical values representative of the status of their angular speed and torque moment, compare said numerical values with ratios of preset numerical values of said angular speed and said torque moments and send signals to said support and at least one printing body in order to correct any possible variations in said values which fall out with said ratios.
A process for the printing of non-woven-fabric comprising the steps of:
- providing a non-woven-fabric sheet;
- providing an equipment for printing on non-woven-fabric comprising a driven support for the transportation of said non-woven-fabric and at least one driven printing body;
- feeding said equipment with said non-woven-fabric sheet;
- performing the printing on said non-woven-fabric under the control and command of a control and command unit,
- wherein said control and command unit is operatively connected with said support and at least one printing body such as to detect electrical signals originating from said support and at least one printing body, turning said signals into numerical values representative of the status of their angular speed and torque moment, comparing said numerical values with ratios of preset numerical values of said angular speeds and said torque moments and sending signals to said support and at least one printing body in order to correct any possible variations of said values which fall out with said ratios.
Equipment for printing on non-woven-fabric, comprising a driven support provided with through holes so as to transport a sheet of non-woven-fabric, at least one driven printing body for implementing the printing and driven holding means which interact with said support in order to hold said sheet onto said support.
