In a bar coating apparatus which applies a coating liquid to a continuously running web using a columnar bar which rotates by being supported by a bar receiving member, the bar to be used is determined based on D*, where A is a deflection value of a difference between a maximum value and minimum value of roundness of the bar, B is a value obtained by a second-order approximation of A in a width direction X of the bar, T (=A&#x2212;B) is a value obtained by subtracting B from A, and D* is an average inclination which is an average of a bar width of an absolute value |dT/dX| of a differential value of T in the width direction X of the bar.

Apparatus and method for bar coating

A bar coater includes: a bar for applying a coating liquid to a web; a support member which is arranged on a lower side of the bar so as to rotatably support the bar; a weir arranged at an upstream side of the bar, the weir having a leading end surface at its distal end portion to form a bead of the coating liquid in a space between the leading end surface and the web; a reservoir including the bar, the support member and the weir, the reservoir for accumulating the coating liquid; a pump for supplying the coating liquid to the reservoir; a liquid discharge passage through which the coating liquid excessively supplied to the reservoir is discharged; and a controlling device for controlling the pump so as not to cause distortion of a dynamic contact line which is formed at interface between the coating liquid and the atmosphere.

Bar coater, and bar coating method

The present invention provides a method for drying an applied film formed by applying an application liquid containing an organic solvent to a traveling long support medium, wherein the temperature Tb of the long support medium before application is not less than 2&#xb0; C. lower than the temperature Tc of the application liquid and the wind velocity in the vicinity of the applied film after application is not more than 0.5 m/s, thereby the applied film is dried uniformly in the initial drying of the applied film.

Method for drying applied film and drying apparatus

According to the drying method and apparatus of the present invention, at first, the coated film on one end side of the support is more quickly dried than that on the other end side, because drying air is supplied from one end side of the support. Subsequently, the coated film on the other end side of the support is more quickly dried than that on one end side, because drying air is supplied from the other end side of the support. Accordingly, the method and the apparatus can diminish a difference between drying rates in on one end side and in the other end side of the long support, in the whole drying zone. Thus, the method and the apparatus can uniformly dry the support and inhibit the production of a dry spot.

Method for drying coated film, and apparatus therefor

In a drying method of an aspect of the present invention, drying steps are conducted immediately after coating in a drying zone, and during the execution of drying by blowing the one-way flow drying wind flowing from one edge side to another edge side in the width direction of the continuous support, the windless drying step is conducted in a windless drying zone provided in the drying zone where the drying wind is not blown.

Method and apparatus for drying coated film

In a coating apparatus of slide bead type for applying a coating solution on a continuously-fed web, each of edge members has a edge member for regulating a width of coating solution flowing on a slide surface. A height Dg of a perpendicular wall of the edge member satisfies a condition Db&#x2266;Dg&#x2266;Ds, when Db is determined as a minimum thickness of bead formed by a coating solution, and Ds is determined as an upper limit of the upper limit of the height Dg. A distance between a web and a front end portion of the edge member is more than 100 &#x3bc;m.

Disclosed is a silver halide photographic light-sensitive material having one or more layers including a light-sensitive silver halide emulsion layer on a support, wherein any of the layers contains the specific fluorine compound. The silver halide photographic light-sensitive material can be stably produced and is imparted with antistatic property.

A web charging apparatus comprises wire electrodes, which are extended along the width of a moving web, and a grounded roller, on which the web is supported. A grounded plate is provided behind the wire electrodes relative to the grounded roller, so that the electrostatic potential at both widthwise ends of the web can be equal to the electrostatic potential at the central part of the web.
