From the surface of the plate material, which is caused in the process of ironing the staying putty agent by frictional contact of the knife blades using two types, or three types of knife blades for filling repair, pretreatment and posttreatment. The pre-collection action of the detached substances and the post-repair action of the linear coating spots generated on the coating film of the semi-finished product are performed separately or simultaneously.

That is, the pretreatment means of the pretreatment knife blade and the dust collecting mechanism for preliminarily collecting the separated substances from the surface of the plate material according to the present invention applies the pressing contact force of the pretreatment knife blade to the plate surface from diagonally above. The generation of debris from the plate material surface that will be caused by frictional contact of the knife blade for filling and repairing in the latter stage by setting the pressure contact force to the plate material surface of the knife blade for filling and repairing in the latter stage Is caused in advance by a pretreatment knife blade arranged in the preceding stage, and is retained and separated near the diagonal gap on the plate material while being preliminarily detached from the plate material surface by the pretreatment knife blade. Occasionally, the knife blade for pretreatment is slid upward so that the object is sometimes discharged backward as the plate material progresses, so that the accumulated object stays backward at any time. This is done at once by means of a dust collection mechanism that is built up directly above the accumulated desorbed matter that is discharged and then discharged backwards as the plate material progresses, for example, by a dust collection mechanism such as a suction means such as a fan or a sweeping means such as a brush. Is configured to be excluded from the machine, and the separated matter is generated in advance on the surface of the plate material immediately before the repair of the putty, and the separated material is recovered.

Further, the means for post-uniforming the linear coating spots generated on the coating film of the semi-finished product by the knife blade for post-treatment of the present invention is a pressing contact force of the knife blade for post-treatment with respect to the coating film of the semi-finished product. Is set appropriately, and due to the clogging of the staying putty agent that has become a highly viscous material that sometimes occurs due to the viscosity change of the staying putty agent that is staying in the knife blade for filling and repairing in the previous stage. The linear coating spots on the product coating are
Since it is a linear coating film with a slightly raised periphery, it is configured so that it spreads evenly with a knife blade for post-treatment before the coating film solidifies in its original form. Then, it is operated so as to repair this immediately after repairing the putty.
