| 4343143 | Binding for fiber bundles, a method for the production of the binding and an apparatus for carrying out the method A binding for bundles of fibers in which fibers originating from at least one of the fiber bundles wind around the rest of the fibers in a manner locked by tension. Fiber bundles which are to be bound are deformed between deformation members and fibers ar... | 08/10/1982 |
| 4338824 | Method of adjusting a given pretension in threads on tensile strength testing apparatus and the like A method of adjusting a given pretension in threads on tensile strength testing apparatus. A force measuring device is used as an adjusting member for the pretension, from where the tensile load increases and the elongation thereby appearing is measured. ... | 07/13/1982 |
| 4311958 | Capacitive thread stopping motion A method and device for detecting the presence of a running thread takes advantage of the inherent physical irregularities of the thread to generate an alternating current signal as the thread passes through a capacitive element. The variations in capacit... | 01/19/1982 |
| 4051722 | Method and apparatus for measuring irregularities in the cross-section of yarns, roving, bands and the like A method of, and apparatus for, measuring irregularities in the cross-section of yarns, rovings, bands and the like, by means of a preferably portable measuring apparatus or device providing a direct read-out or display and containing a measuring element,... | 10/04/1977 |
| 4016790 | Regulation of electronically operated quality control equipment This invention relates to the art of quality control, more particularly to the regulation of electronically operated quality control equipment such as yarn cleaners, or the like so that the quality control equipment may be selectively adjusted to eliminat... | 04/12/1977 |
| 3971272 | Regulation of electronically operated quality control equipment A method for regulating the operation of yarn clearers having error correcting means such as yarn cutters, and sensing means providing an electrical signal representative of the controlled quality. The method comprises the steps of: feeding the signal fro... | 07/27/1976 |
