MOVABLE CUTTING-OFF MACHINE WITH CIRCULAR SAW FOR CONTINUOUS CROSSWISE HIGH-SPEED CUTTING OF EXTREMELY LONG WOODEN PARTS Russian patent published in 2009 - IPC B27B5/29 

FIELD: mechanics.

SUBSTANCE: proposed machine comprises a working tool with a circular saw disk 3D operating along the working table guided by, at least, one guide channel accommodating at least one running guiding wheel fitted on the working tool casing. The guide channel arranged above the working table and working tool features, in plane, a twisted or bending shape with at least two bends directed in opposite directions. The latter allows the distance X between the bands to be equal to the width of the circular saw crosswise cut and to considerably exceed the width of the said extremely long wooden part. At least one inclined cut is made in the frontal plane of the fixed working table sliding above the working tool. The lengthwise carriage accommodates a clamping device provided with at least one pair of side cams. Note that the said clamping device is arranged ahead of the working tool and above the working table to form with at least one inlet flap moving vertically, an inlet guide channel for the said extremely long part.

EFFECT: higher accuracy and speed of crosswise sawing.
