Abstract:
A device on a spinning preparation machine, for example a tuft feeder, having a feed device comprising at least one slow-speed feed roller and a counter-element, for example a feed tray, with which fibre material can be supplied to a downstream transport device, has a driven transport element, for example a conveyor belt. In order to provide improved delivery from the feed device, or improved takeover by the downstream transport device, and to allow troublefree operation, for the purpose of determining setting values for the optimum speed of the transport element, a function between the measured values of the feed roller speed and the measured values of the transport speed is so determined that the fibre material lies on the moving surface of the transport element.
Abstract:
In an apparatus for producing a fibre web, for example of cotton, synthetic fibres or the like, a web-former and/or a web-bonder is/are arranged downstream of a flock feeder device and the fibre material is conveyable. In order to make it possible by simple means to produce a uniform fibre web, a drafting device is arranged between the flock feeder device, on the one hand, and the web-former and/or the web-bonder, on the other hand, for drafting of the flock material.
Abstract:
In an arrangement for mixing fibre components, for example fibre flocks, especially in spinning preparation, fibre web production or the like, in which the fibre material to be supplied is conveyable into at least two weighing containers and, when weighing is complete, the fibre material is dischargeable from the at least two weighing containers onto a mixing belt, the weighing containers are arranged one after the other—seen in the direction of travel of the belt—above the mixing belt. In order that accurate weighing, troublefree production and increased throughput can be achieved in a simple manner, the position of at least one weighing container can be adjusted transverse to the longitudinal extent of the mixing belt.
Abstract:
In an apparatus for operating a feed device for fibre material, for example, a hopper feeder, there is provided a drivable, endless conveyor belt guided around two rotatable rolls. The conveyor belt is associated at one end, looking in the conveying direction, with an endless, upwardly inclined spiked lattice. Upstream of the other end of conveyor belt, looking in the opposition direction to the conveying direction, there is arranged an endless feed belt (reserve belt) for receiving fibre bales or the like. To convey fibre material to the hopper feeder in a simple manner, without interruption to production, there is arranged between the conveyor belt and the reserve belt 8a continuously circulating transition belt, and the absence of fibre material on the reserve belt is detectable.
