Appl. No.:

6/072740

Inventors:

Robert W. Davenport - Golden CO
Eugene L. Moore - Lakewood CO

US Classification:

51 54

Abstract:

Apparatus for grinding a helical cutting surface on a flat cutting blade. Prior art grinders are complex, difficult to operate and expensive to use. The present grinding machine comprises a stationary support (74), a grinding arbor (76), an adjustable cam plate (78), a grinder carriage assembly (80), a grinder assembly (82), cam follower (112), mounted on the grinder carriage assembly (80), and a grinding stone (128) mounted on the grinder carriage assembly (80). When the carriage and the grinding stone are reciprocated along the axis of rotation of the grinding arbor the cam follower (112) contacts the lower surface of the cam plate (78) whereby the grinding arbor is oscillated about its axis of rotation and a helical cutting surface is ground into the blade (34).

Abstract:

Clamps mounted on a reciprocal frame grip a web of connected molded fibrous articles and move toward a cutter a distance equal to one article length, thereby presenting to the cutter the connecting portion between adjacent articles and also pulling the next portion of uncured fibrous material into the mold press for shaping and curing. After the cutting operation the clamps open and move toward the mold into position to again grip and feed the web toward the cutter. Connected rows of webs can also be handled by slitting the rows as they move toward the cutter. The articles, which can be quite deep compared to the thickness of the connecting portions between articles, are supported during travel and while stationary by support plates separate from the reciprocal frame. The various components which contact or cause movement or cycling of the apparatus can be adjusted to permit handling of articles and webs of different dimensions.
