摘要:
The improved racla device (1) to be mounted in an apparatus for coupling fabrics by means of a glue, contains a reservoir (2) for collecting the glue, a knurled roller (3) and the reservoir (2) is in contact with the surface of the knurled roller (3). Further the device (1) is composed of a slab (10) which is provided at its lower end with a metallic lamina (11) which closes the bottom of the reservoir (2), while keeping always the contact with the surface of the roller (3).
摘要:
Methods of applying a polymer coating to a substrate are disclosed. By disrupting a bank (8) of polymer precursor, a smooth coating of fast setting polymer can be applied to a substrate. Apparatus (5) for applying a polymer coating is also disclosed. In one embodiment, an oscillating dispenser is used to apply polymer precursor onto a dispersive surface (30). The polymer precursor flows down the surface (30) and is transferred to a moving web (50). Flowing solvent downwardly through the dispenser can provide efficient cleaning without the need for disassembly or production delays.
