| 5426823 | Method and apparatus for on-line quality monitoring in the preparatory apparatus of a spinning mill The fluctuations in cross-section of fiber slivers are detected by means of a sensor, and from these detections are derived quality parameters, one of which is based on mass non-uniformity. Measurement signals are compared with a limit value for deviation... | 06/27/1995 |
| 5194911 | Method and apparatus for determining the quantity of material transported within a fibre band or sliver A fibre band or sliver is passed through a defined opening of a measuring station. Said opening has a cross section smaller than the diameter of the fibre band, so that the band contacts the walls of said opening which thereby defines a measuring cross se... | 03/16/1993 |
| 5157810 | Apparatus for measuring the mass of a sliver For use in a spinning mill, the apparatus is used to even up the mass of sliver being conveyed, for manufacturing perfect roving yarns. The evening up takes place by measuring the thickness of the sliver after it has been compressed to a certain volume in... | 10/27/1992 |
| 5123280 | Device for measuring the thickness and/or the unevenness of slivers A sliver measuring device includes a pair of rollers (6, 7) which limit two sides of a rectangular measuring space (3). A third side of the measuring space (3) is closed off by a guide roller (8) or by a guide plate. A measuring element (5) for the thickn... | 06/23/1992 |
| 4987648 | Combing machine with workstations having a monitoring unit at each workstation The combing machine is provided with a plurality of workstations each of which is provided with a table containing a funnel through which a combed web is formed into a sliver. Each table is pivotally mounted on a fixed shaft and a monitoring unit is provi... | 01/29/1991 |
| 4969244 | Warp beam depletion monitoring apparatus and method An apparatus and method is disclosed for monitoring depletion of yarn from a textile warp beam wherein yarn actually remaining on the beam is measured radially with respect to the beam, compared with a preselected radial dimension of yarn desired to remai... | 11/13/1990 |
| 4962569 | Method and apparatus for obtaining measuring values representing the thickness of a coherent fiber mass An apparatus for generating measuring values representing the thickness of a coherent fiber material, includes an optical device having a light transmitter emitting a light beam and a light detector, an arrangement for guiding the fiber material between t... | 10/16/1990 |
| 4955266 | Apparatus for detecting the density or thickness and variations thereof of fiber material at the infeed of a textile machine as well as for evening the density of thickness variations of fiber material at the infeed of a textile machine A fiber infeed device supplies fiber material to a textile machine, such as a card, and comprises a driven rotatable feed roll and feed plate. This feed roll is, however, spatially fixed, whereas the feed plate is pivotable but physically immobile during ... | 09/11/1990 |
| 4646387 | Arrangement for continuously determining the density of a web of fiber sliver An arrangement for continuously determining the density of an elongated strip-shaped web of fiber sliver in the course of a spinning process in order to generate control signals for use in controlling the operation of machine elements operative for equali... | 03/03/1987 |
| 4400850 | Foreign object detector for protection of carding machines A mechanical foreign object detector upstream from the feed roll of a carding machine faithfully detects minute hard objects in the lap which could damage the lickerin or other components of the card. Spring-loaded detector pins penetrate through the lap ... | 08/30/1983 |
