  • Patent number: 8361554
    Abstract: 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?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.

  • Patent number: 7727594
    Abstract: 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.

  • Patent number: 7722930
    Abstract: 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.

  • Publication number: 20090302495
    Abstract: A dope (21) is cast from a casting die (30) onto a casting drum (32) that is moving. The dope forms a bead (21a) between the casting die and the casting drum. Provided downstream from the bead in a casting drum's moving direction is nozzles (61a, 61b) which supply a solidification preventive solution around side ends (22b) of a downstream surface of the bead. On an upstream side of the bead, air pressure is reduced by a decompression chamber (36). Since the bead separates airflow of the upstream side from the downstream side, the solidification preventive solution is not blown in the airflow from the upstream side.
