ABSTRACT:
The disclosure herein describes an anti-kickback device for use in a wood ocessing machine. The invention is concerned with mounting, upstream of an arrangement of circular saws, a series of fingers pivotably mounted on a shaft mounted transversely of the frame. Each finger is characterized by a curved edge, facing the lumber passing by, on which is mounted a series of peripherally spaced lumber-engaging pointed elements, each element defining a different angle with respect to the pivot axis of its shaft. Each lumber-engaging element consists of a support which is removably mounted to the curved edge and a blade, preferably made of carbide material, fixed to this support.
