Abstract: In a veneer lathe having a knife mounted to a knife support frame with a backing plate, a roundup control system for a veneer lathe is disclosed that recognizes or detects the production of usable veneer using the body of the knife as a signal source. During initial production of veneer, the lathe produces a trash or roundup veneer that is directed to a chipper through a trashgate. When there begins production of usable veneer, the trashgate is closed and the usable veneer is directed toward production trays or stackers. A sensor or displacement detection device is mounted in the backing plate of the knife support frame lateral the unsupported portion of the knife. As the knife contacts wood, the unsupported span of the knife flexes causing the magnet to move which the sensor detects. The sensor outputs a voltage signal proportional to movement of the knife in magnitude and direction. This voltage signal is relayed to a central processing unit where it is converted into a digital signal.

Abstract: A device which trims off the perforated margin strips of printer paper and cuts the paper transversely to separate it into individual pages. The paper which discharges from the printer is drawn around a tension bar and is applied to a toothed belt driven by feed wheels. Cutter wheels act against a grooved roller to cut along the tear lines of the margin strips. A photocell based counting system counts the perforations which pass the photocell to indicate each time the paper is advanced to position one of the transverse fold lines at a cutting station. Then, the paper is stopped and a cutter wire is pulled through the fold line to separate the leading page from the rest of the paper sheet. Each time a new sheet of paper is loaded, a special control circuit assures that the initial advance of the sheet stops with the leading edge of the paper at the cutting station.

Abstract: A cooperative conveyor system for a lumber production line. The production line has a canting station and a sawing station spaced at a distance from each other and interconnected by a powered conveyor system. The cants are fed at a higher rate through the canting station than through the sawing station. The conveyor system is arranged to receive cants from the canting station at a high feed rate and transport the cants to and into a sawing station at a lower feed rate. The cants are fed through the canting station at controlled intervals so that the resulting gap between succeeding cants received on the conveyor are at a desired spacing to maximize the production of the sawing station. The cant exiting from the canting station is forced to overrun the conveyors feed rate and thereby reduces the gap between it and a preceding cant. The conveyor then transports the cant to and into the sawing station at the desired feed rate for the sawing station. In one embodiment, the sawing station has two saws.

Abstract: Printed elastic bands are made by piercing, evacuating and flattening an elastic tubing and washing and scrubbing and drying the upper surface of the tubing, aligning a tubing on a conveyor and moving the tubing upward toward a printing head and quickly downward away from the printing head while maintaining the tubing flattened. The printing is devolatilized and cured while the tubing continues to move to the cutoff point. Nip rollers drive a tubing onto a cutoff platen, a final roller near the edge of the platen has a higher surface speed than the nip rollers to flatten the tubing. Printing on the tubing is sensed and rotating knives are sensed and the speed of the nip rollers is controlled to cut the tubing between the printed areas. Severed printed bands are removed by vacuum and are discharged from a cyclone separator.

Abstract: Metal billets are cut from heated logs emerging from a furnace by a shearing system controlled by information detected as the logs emerge from the furnace. Detection in this position eliminates the variations inherently present in the length of the logs resulting from temperature gradients within the furnace, and from a length of time the logs are subject to these gradients. The advancing end of an isolated log is sensed by an electric eye, and the interface between one log and the following log is detected by an eddy current device. The data from these sensing devices is supplied to a computer, which controls the shearing operation so that billets can be cut with a minimum of waste. The billets can be of two segments, and the equipment establishes cutting operations that produce the combined billet length, regardless of the position of the interface between the logs.

Abstract: A slide-fastener stringer is pulled through a gapping station by a motor operatively engaging the stringer without slip and at least one feed roller engaging the stringer upstream of the gapping station.

Abstract: Disclosed are a method and an apparatus for cutting drawings from a web that has emerged from a computer controlled graphics plotter. The apparatus includes a support for holding the spool of paper from the plotter and a drive means for pulling the paper through the apparatus. Photocells serve as sensors for detecting the presence of the four borders of each drawing. In response to signals generated by the photocells, the transverse borders are cut by a rotary scissor during pauses in the advance of the web. The side or "longitudinal" borders of each drawing are cut by a pair of knives that pierce the paper and cut the borders as the web is being advanced through the apparatus.

Abstract: Disclosed is a method and apparatus for removing wastepaper (W) from a continuous web(2) of photographic paper upon which photographic images (P.sub.1, P.sub.2 . . . ) have been printed. Between each photograph there exists a cut mark (4) that instructs a photographic print cutter (1) where one photograph ends and an adjacent photograph begins. The method comprises advancing the web to a point where a cut mark is expected and sensing the presence or absence of a cut mark. If a cut mark is sensed, the web is advanced to align the cut mark under a cutting knife (8) and the cutting knife is cycled. If a cut mark is not sensed, the web is reversed a predetermined reverse length before the cutting knife is cycled. By reversing the web the predetermined reverse length, it is assured that any length of wastepaper cut from the web will at least be as long as the reverse length. The reverse length is long enough to prevent jamming of the print cutter.
