Abstract:
A grinding device for the flats of a card comprises elastically bendable elements which enter between the clothing points, brush over the side flanks of the points and thereby grind the points. Additional grinding elements are provided in order to treat the front sides of the clothing points. The ground-off material may be removed by a suction device.
Abstract:
A drive belt assembly for a revolving flat card includes a flexible belt. At least a pair of connecting elements are integrally formed with the belt. The connecting elements include a cross-beam with an inclined surface. A locking element is disposed between the pair of connecting elements in order to prevent the connecting elements from approaching one another. The locking element is removable from the pair of connecting elements to allow for the approaching of the connecting elements to one another.
Abstract:
In a plant for processing textile fibers, the fine cleaning is effected at a point at which the stream of fiber material already has been subdivided (e.g. for the subsequent carding process), e.g. in the card filling chute. The cleaning device comprises at least one separating element arranged above the transporting roll. The trash eliminating system includes a system for eliminating material separated from the zone of the roll.
Abstract:
The carding distance (KA) between clothings (14, 15) is scanned using an optical device (22, 26) e.g. using a laser beam (24) from the side of the working area. The measuring value thus obtained can be compared to a pre-set target value in such a manner that the distance mentioned can be adjusted. Card with a controllable actuator system (32, 34) for setting the carding gap between the clothing on the main drum and the clothing on the flats, and with a programmable control system (12) which can influence the actuator system. A sensor system (26, 28) measures the carding gap in order to render regulation of the gap possible. The control system obtains, and processes respectively, data connected with the state of the clothing. The control system (12) is programmed in such a manner that regulation is effected as long as the measuring values supplied by the sensor system appear to be "plausible". If the plausibility no longer is ensured, the control system can deactivate the regulation steps and possibly can itself take over the adjustment process.
Abstract:
The invention describes the development of a new buffer system for cell culture media for establishing a CO2 regulation in the bioreactor with eukaryotic cells. This technology makes it possible to obtain CO2 regulation for process control, process optimization and scaling. In addition, the invention describes a specific cell culture medium with specific buffer substances.

Abstract:
Method for producing a card sliver and carding machine therefor. The flexible bend of a card is set automatically by the machine control by means of a controllable actuator system on the basis of a wear characteristic, this characteristic representing the wear as a function of the production of a given material.
Abstract:
The invention relates to fastening means (in particular to so called clothing clips) for the fastening of clothing strips on flat rods, made of light metal or light metal alloys. Thereby the fastening means are laid-out in such a manner that, when the flat rods assume their operating temperature, these are not deformed.
Abstract:
A grinding device for the flats of a card comprises elastically bendable elements which enter between the card clothing points, brush across the lateral surface of the points and thus grind them, whereat the material that has been ground off is removed by a suction means. The grinding device may be portable so as to be used on different card machines. A control system may be provided to engage and operate the device in an interrmitten manner.
