  • Patent number: 5845760
    Abstract: A cheese conveying system has an interface belt centrally trough-shaped along its length and disposed to span between the outlets of two delivery belts and to extend therefrom to the inlet of a collection belt, by means of which cheeses transported from the delivery belts in a lying position roll transversely to the center of the interface belt to accomplish a gentle uncomplicated transfer of the bobbins from the delivery belts to the collection belt. The delivery belts are alternately actuable and the respectively delivery, interface and collecting belts are driven at the same speed.

  • Patent number: 5600945
    Abstract: Spinning stations of open-end spinning frames are cleaned from time to time to increase productivity, e.g. each time a sliver can change is made although, if the times between the exchange of two cans are too long, cleaning may be performed at a preset cycle. The sliver must be removed from the spinning station for this purpose. To be able to reintroduce a defined length of the removed sliver into the spinning station at the end of a cleaning operation, the end of the sliver is aspirated from between the draw-in roller and the gripping table of the spinning station by means of an aspiration and blower nozzle and pulled out of the spinning box of the spinning station and, after the cleaning operation, the sliver is introduced into the spinning station by means of the aspiration and blower nozzle. The aspiration nozzle has an insert with bores for causing the tip end of the sliver to assume a particular shape.
