  • Patent number: 6157730
    Abstract: A visual inspection system particularly designed for imaging relatively non-rigid materials. In order to identify defects and the position of defects and the position of defects on the material. The arrangement is particularly designed for handling leather hide. Defects in leather hide are presently identified by manual inspection. The present invention provides a visual inspection system for non-rigid materials comprising a mounting means for mounting a sample of the material, tensioning means for tensioning at least an area of the sample, an imaging means (3) for obtaining an image of the area of the sample under tension and processing means for processing the image to provide information on any defects which may exist.

  • Patent number: 4236534
    Abstract: The height of a continuous tobacco stream between a first side which is supported by a conveyor and an uneven second side is monitored by an opto-electrical level detector which directs a row of parallel light rays transversely across the stream and has a battery of photosensitive elements at different distances from the first side of the stream so that each element produces a signal in response to impingement of a different light ray upon its photosensitive surface. The number of elements which generate signals is indicative of the height of the stream portion advancing past the level detector. Such signals can be utilized to adjust a trimming device which removes the surplus at the second side of the stream before the thus equalized stream enters a wrapping mechanism to be converted into a cigarette rod which is thereupon severed to yield discrete cigarettes.

  • Patent number: 4190061
    Abstract: An adjustable distributor transports particles of tobacco into a stream building zone wherein the tobacco is converted into a stream containing a surplus of particles. The surplus is removed by an equalizing device and the equalized stream is converted into a rod-like filler. An optical level detector monitors the height of the stream ahead of the equalizing device, and a second detector monitors the height of the equalized stream. Signals which are furnished by the detectors are transmitted to the corresponding inputs of a dividing circuit whose output transmits signals which are used to adjust the distributor in such a way that the rate of tobacco transport to the stream building zone is increased when the quantity of removed surplus decreases and vice versa. The equalizing device, together with the second detector, is movable transversely of the tobacco stream in response to signals from a detector which monitors the density of the filler.

  • Patent number: 4131501
    Abstract: A fresh web of cigarette paper or the like is spliced to the running web by a uniting band, which is adhesive at both sides, after the fresh web is accelerated to the speed of the running web. The uniting band is placed between the running web and the leader of the fresh web, and the running web is shifted sideways to adhere to the adjacent side of the uniting band as well as to move the other side of the uniting band against the fresh web as soon as the speed of the fresh web rises to that of the running web. The running web is severed behind the moving uniting band, and the fresh web is severed ahead of the moving uniting band. Severing of the fresh web is preceded by relaxation of tensional stress upon the leader of the fresh web in response to displacement of a guide roller which engages the fresh web between a stationary knife for the fresh web and a pair of motor-driven advancing rolls which pull the leader of the fresh web in the course of and subsequent to completed acceleration of the fresh web.
