Debarking machine

A debarking machine having a wood-infeeding side for feeding wood to said debarking machine and a wood-outfeeding side for outputting wood from said debarking machine, said debarking machine comprising:

• one of a line of first to n-th rotary members coupled in series, and a plurality of lines thereof coupled in series, from said wood-infeeding side to said wood-outfeeding side, each rotary member having a debarking blade on an outer surface,
• wherein said first rotary member is inclined downwardly in a direction toward said wood-outfeeding side from said wood-infeeding side and said second to (n-1)-th rotary members are arranged one of horizontally and inclined downwardly in said direction toward said wood-outfeeding side from said wood-infeeding side,
• wherein an inclined angle of said first rotary member located at an end of said wood-infeeding side is set greater than an inclined angle of said (n-1)-th rotary member located before an end of said wood-outfeeding side, and
• wherein inclined angles of said second to (n-2)-th rotary members are set within a range from an angle no less than said inclined angle of said (n-1)-th rotary member to an angle no more than said inclined angle of said first rotary member and are each set no less than said inclined angle of an adjoining rotary member which is located on said wood-infeeding side.
