Abstract: An image forming device includes a first detection sensor unit that detects a toner image formed on an image carrier; a second detection sensor unit that detects the toner image disposed to be separated in the main scanning direction with respect to the first detection sensor unit and formed on the image carrier; and a controller. The controller causes: an image carrier to carry toner images indicating a first test pattern and a second test pattern, and discriminate a difference from a determination condition with respect to a first determination result based on a first threshold value and a second determination result. The controller determines a component to be an occurrence cause of the difference based on a combination of the first determination result and the second determination result when it is determined that the difference is present.

Abstract: Yarns are deposited on a conveyor belt in the form of random or ordered loops and are conducted through a yarn treating chamber. The treated yarn is drawn from the belt at a predetermined draw-off site. The position of the last yarn loop adjacent the draw-off site is scanned by a sensor, and the draw-off velocity is controlled as a function of deviations in the location of this last yarn loop. At the draw-off site a holding device is provided to press the looped yarn against the conveyor belt. During any interruptions of the drawing-off operation, the yarn will accumulate on the conveyor belt. The holding device and sensor are mounted to a slide which relocates the sensor and holding device downstream to a position in the vicinity of the last yarn loop so that the holding device will act on the yarn when the drawing-off operation is resumed. The holding device is then moved upstream along with the last yarn loop as the drawing-off operation proceeds.

Abstract: An apparatus and method for controlling a plurality of connected continuous paper printing machines connected in series prevent difference in rotational speeds of the connected printing machines from causing the paper between the printing machines from piling up or tearing. Signal generators count the number of sheets of continuous paper entering each printing machine. The difference in the number of sheets entering each printing machine is calculated and compared to preset upper and lower limits. If an upstream printing machine turns faster than a downstream printing machine, slack will develop in the paper between the printing machines, and the difference between the sheets entering the upstream printing machine and sheets entering the downstream printing machine will be a (+) value. When a preset upper limit is reached, a controller will temporarily stop the upstream printing machine until the downstream printing machine takes up all the slack.

Abstract: Modular web processing units may be physically and electrically assembled into clusters to perform various web processes (e.g. the production of paper forms such as invoices, checks, labels, etc.). Each module has a main process driver which is not directly coupled to a web drive mechanism. Rather, the web drive is program controlled so as to effect the desired web process at controlled displacement intervals along the web. Accordingly, a plurality of successive but different form lengths or depths can be accommodated as the web surface is sequentially processed. A system of such modules can be physically wheeled into position as individual units and electrically connected together by suitable umbilical cords to rapidly configure a desired overall web finishing process. Nevertheless, the entire ensemble of modules performs as though it is a unitary special purpose web processing machine with its various process stations interconnected and synchronized by an electronic "drive shaft".

Abstract: Apparatus for controlling the tension of a web during transport, such as a label-carrying web in a heat transfer labelling machine. The web travels from a supply reel, around a dancer roll and metering roll, through various other web handling devices to another dancer roll, and is collected at a rewind reel.
