Abstract: A three-knife sheet trimmer is so constructed as to separate the drive for the knives (one front knife and two side knives) from the drive for the clamps which hold the sheets (e.g., the sheets of a book) stationary while being trimmed. The knives at the stations are operated out of phase, and the moving masses are therefore balanced compared to the previous form of these trimmers where all knives move in the same direction at the same time. Separating the drives also enables a book to be sooner advanced from the first knife station to the second knife station. This being so, there is a greater allowance of time in which to make the transfer, and hence there is no need to rush the book.

Abstract: Battery grid plate castings are trimmed in a two-step operation. Each plate moves flat along a horizontal or inclined path against a first stop bar. One of two trim blades on a reciprocating upper die block then shears flashing from the leading end of the plate during a downward stroke of the die. Then the stop bar raises during the upward stroke of the die, and the plate moves forwardly against a second stop. Upon the next downward die stroke the second trim blade shears flashing from the trailing edge of the plate. During the next upward stroke, the fully trimmed plate moves forwardly onto a stacking device. As the leading end of one plate is trimmed at the first trim station, the trailing end of a preceding plate is trimmed at the second trim station. The second stop is easily moved to different stop positions along the path of travel of the plates to change the distance between such stop and the second trim blade and thereby enable trimming plates of different lengths without changing dies.

Abstract: An in-feed conveyor brings individual pieces of lumber to an examining area, where a carriage is movably mounted relative to the conveyor for movement along the piece of stock. A control on the carriage is triggered whenever the carriage is positioned in predetermined alignment with defects in the stock, including undesirable end portions as well as structural or quality defects intermediate the ends of the piece. Triggering such control sends an input to a computer, which controls the cutting of the stock by a saw located downstream from the examining station, by which the defects are cut out of the piece of stock. The computer completely controls the incremental movement of the piece of stock at the saw, automatically stopping the stock and causing the same to be cut, not only to remove defects, but also to produce an optimum yield of different pieces cut from the good stock between the defects.
