    Abstract: An apparatus and method of flowing a fluid onto an incline planar surface across the entire with of the slot has a slot capillary number less than 0.04. The slot exit gap S is selected to be less than ##EQU1## where S is the slot gap in cm, .mu. is the fluid viscosity measured in poise, .rho. is the liquid density measured in gm/cm.sup.3, .sigma. is the liquid surface tension measured in dyne/cm, and N.sub.re is the Reynolds number as defined by N.sub.re =4M/.mu., where M is the liquid flow rate per unit of width measured in gm/sec-cm. The expression for a is defined as 0.981+0.3406 log N.sub.re.sup.0.3406. The fluid is flowed through a slot exit.

    Abstract: A coating method and an extrusion-type coating head in which turbulence at the junction between two flows of coating materials is prevented to provide multi-layer simultaneous coating over a wide range of coating rates and with a good coating quality. An intermediate block is sandwiched between a rear block defining a back edge and a front block defining a doctor edge. Two coating flows pass through slits formed on either side of the intermediate block, joining at the top end of the intermediate block and flowing together into a short slot extending between the end of the intermediate block and the outlet of the head.

    Abstract: A method of forming a multilayer coated film comprising applying two or more nonaqueous layers to a continuously traveling flexible web, wherein at least one of the two or more coated layers comprises a coating composition containing an electron beam hardenable resin, and at least one of the two or more coated layers has a viscosity of about 100 cps or more, and irradiating the two or more coated layers with electron beams to harden the coated layers or increase the viscosity thereof, and thereafter drying the coated layers is disclosed.

    Abstract: In a method for coating a surface with a layer the surface is first subjected to vacuum in a vacuum zone (V) sealed against the surface, whereupon liquid for forming the layer is supplied to the surface in a sealed pressure zone (P) following the vacuum zone. The supplied liquid is then spread out in a controlled manner, preferably by the sealing (13) terminating the pressure zone. FIG. 1.
