Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to an eye-stop colorant wiper for woodworking.

Conventionally, the wiping off of the coloring agent applied to the decorative finishing material having the uneven surface, the curved surface, or the complicated surface such as engraving has traditionally been done manually only by the worker. It required a considerable amount of time and effort, and there were problems such as individual differences and skill levels.

Moreover, it is no exaggeration to say that wiping off the eye-blocking colorants on wooden products is determined by the quality of the finish in the painting process.

The present invention has been made to solve the above problems and to make it possible to finish evenly any uneven surface and to efficiently finish the coloring in a short time, which is characterized by a constant horizontal length. Consists of an endless belt for conveyance that rotates in a range and a plurality of wiping heads that have rotating brush rolls for wiping, and each wiping head is rotated while horizontally rotating in the running direction of the endless belt. Each of the cleaning brush rolls is arranged so as to be overlapped with each other so as to come into spiral contact with the object to be treated.

Hereinafter, an example of implementation of the device of the present invention will be described with reference to the accompanying drawings.
