A dye applicator for dyeing materials, a dye application kit, and a method for manufacturing the same are provided. The dye application kit has at least one container containing a dye applicator being at least partially fibrous and infused with a dry water-soluble dye, the dye being transferrable to an adjacent article in the presence of water

According to an aspect of the present disclosure, an airfoil apparatus is provided which minimizes entry of entrained air into a system having a controlled internal environment, such as a corona treatment system, such entrained air resulting from a high-speed web moving into the system. According to another aspect of the present disclosure, the airfoil apparatus is rotatable relative to the system so that the airfoil apparatus can be adjusted to changes in the web.

According to an aspect of the present disclosure, a color sensor is provided for sensing whether a ground roller in a corona treatment system needs to be serviced. The color sensor is capable of detecting imperfections which have changed the reflectance level of the ground roller from a predefined level. According to another aspect of the present disclosure, if a determination is made that the ground roller needs to be serviced, then an alarm is activated and/or the operation of the corona treatment system is ceased.

The invention relates to a printing machine and a method for printing textiles with a machine bed, at least one conveying means arranged on the machine bed for conveying at least one textile along a processing path, at least one priming means arranged on the machine bed for applying a primer in a planar manner on a motif region of the textile, on which a print motif is to be provided, and at least one printing means arranged on the machine bed and having at least one digital print head for printing the print motif. In accordance with the invention provision is made in that along the processing path between the priming means and the printing means at least one pressing means is arranged which is designed for pressing the motif region with the applied primer.
