摘要： A drive system for a drawframe for a rove drawing process in which the drawframe includes at least one pair of feed rollers, at least one pair of sleeves, at least one pair of drawing rollers, and at least one swinging arm on which one feed roller, one sleeve and one drawing roller of each pair is supported, the swinging arm being displaceable between an inoperative position and an operative position where the pair of feed rollers, pair of sleeves and pair of drawing rollers are engaged under pressure for rove drawing. The drive system includes a drive shaft and at least one displaceable friction clutch roller which is displaceable between an operative position to engage both the drive shaft and one of the feed rollers for transmitting drive from the drive shaft to the feed roller, and an inoperative position where it is disengaged from the feed roller, the friction clutch roller being displaceable into its operative position to allow progressive engagement of the drawframe at start up.

摘要： Apparatus for preparing spun yarn comprising back rolls for feeding fiber from a supply thereof to front rolls spaced from the back rolls and serving to draft fiber received therefrom. A stretch breaking zone and a draft zone are arranged in succession in that order between the back rolls and the front rolls. An endless bottom apron extends between the back rolls and front rolls over the stretch breaking zone and the draft zone, and the bottom apron passes on respective support plates adjacent the back rolls and front rolls. Output rolls are mounted in the stretch breaking zone for drawing fiber from the back rolls and stretch breaking the fiber, and input rolls are provided in the draft zone for receiving fiber from the output rolls and for advancing the fiber to the front rolls. Both the input and output rolls include top and bottom rolls for advancing the fiber therebetween. The bottom apron extends on and is driven by the bottom rolls of the input and output roll means. A first top apron is mounted in the stretch breaking zone, and a second top apron is mounted in the draft zone, the first top apron passing on a further plate and on the upper roll of the output rolls in the stretch breaking zone and driven by the latter, the second top apron passing on a further plate and on the upper roll of the input rolls in the draft zone and driven by the latter. The first and second top aprons are opposed to the bottom apron to control the feed of the fiber therethrough.

摘要： A drafting system unit for a drafting system of a spinning machine having a first top roller and a second top roller spaced apart therefrom, characterized in that an apron cage to which negative pressure can be applied is arranged between the first top roller and the second top roller for guiding an air-permeable apron in circulation jointly around the apron cage and an apron top roller, the apron top roller being formed by the first top roller or by a third top roller that is assigned to the apron cage and arranged on the same side as the first and second top roller in relation to the fiber band being transported. The apron cage has at least one through-opening, to which negative pressure can be applied, for applying suction air to the fiber band running between the first and second top roller, through the air-permeable apron.

摘要： A drafting assembly for drafting a fibre web having upper and lower rear apron loops which have first and second support surfaces respectively being arranged to grip the card web fibres between them and transport the card web fibres from a rear entrance to a rear nip point on displacement of the rear aprons. Upper and lower front apron loops have third and fourth support surfaces, respectively, being arranged to grip the card web fibres between them and transport the card web fibres from a front nip point to an exit on displacement of the front aprons. The front and rear nip points are adjacent and arranged such that the front nip point receives card web fibres which exit the rear nip point. Proximate to the nip point, each loop is wedge shaped with the arms of the loop on each side of the nip point converging towards nip point and having an acute angle therebetween.

摘要： A double-apron drafting unit for spinning machines has a delivery roller pair and an apron pair arranged upstream therefrom. The apron pair guides a fiber strand in the area of a delivery nipping line, with which it forms a wedge-shaped gap. Devices are provided for keeping air currents, which circulate with the delivery roller pair, away from the area of the delivery nipping line, which devices are located outside of the wedge-shaped gap point formed by the delivery nipping line and the apron pair. The devices are, however, located in direct proximity to the delivery roller pair and the apron pair.
