Definitions

  • the invention relates to a high-speed card for the formation of nonwovens from thermoplastic fibers, - from the support table, feed rollers, roughing rollers, at least one main roller with associated workers and turner, and take-off rollers, the rollers having toothed surfaces.
  • the fibers are fed in from the support table via the feed rollers to the preliminary rollers, which provide the so-called preliminary opening.
  • the fleece is formed with longitudinally oriented fibers and then random layers are formed.
  • the course of the goods from the open fleece template to the acceptance of the finished fleece pile is determined by the direction of rotation and tooth shape of the individual rollers.
  • the saturation temperature at which there is a balance between the frictional heat released and the amount of heat dissipated, is already at medium speeds above the melting point of the fibers. Because of this, the manufacturing process, especially for low-melting fibers, whose melting temperature is around 100 °, interrupted by clumping of the fibers. This will also damage the sets.
  • Another significant disadvantage of known cards is the gap adjustment of the individual rollers for different products. All nips can only be correctly adjusted at room temperature. The set nips are in the order of a few tenths of a millimeter. However, the diameter increases by this amount e.g. a tangled roller with a diameter of approx. 500 millimeters, which is heated from room temperature to 50 °. Before adjusting the gap, wait until the card has cooled to room temperature.
  • the object of the invention is to provide a card of the type described at the outset which enables the highest production output with the greatest uniformity of orientation and weight distribution of the nonwoven produced.
  • At least the thermally most highly stressed rollers are designed as tempering rollers which have channels through which a tempering agent flows.
  • the channels can be arranged in particular in the area of the roll shell. They should extend essentially over the entire length of a roller so that the surface of the roller assumes a uniform temperature.
  • the roll shell of these rolls is kept in a defined, predetermined temperature range by suitable temperature control, in particular of the rolls subjected to the greatest thermal stress.
  • suitable temperature control in particular of the rolls subjected to the greatest thermal stress.
  • the limit is given when the fibers reach the melting temperature through self-friction.
  • deformation of the rolls due to uneven temperature distribution is eliminated.
  • the exact cylindrical shape of the rollers is retained.
  • An adjustment can always be made in the defined, predetermined temperature range and is therefore possible at any time.
  • a fine adjustment of the roll nips is also possible during operation or with tempered rolls. The fine adjustment can also be carried out by raising or lowering the roller temperature. The distribution of the pile over the roll length is not affected by this, since the cylindrical shape of the roll does not change.
  • a temperature sensor can preferably be used as the actual value transmitter of a control for the Temperature of the temperature control and / or the rollers can be provided.
  • the regulation enables an automatic dissipation of the respective amounts of heat generated in such a way that the roll temperature is always constant and thus the cylinder shape and the set roll gaps are retained.
  • Temperature-controlled water with a temperature slightly higher than room temperature is preferably used. If the heat load on a roller is so great that the amount of heat released cannot be dissipated with the temperature control medium of the respective temperature, the control system supplies cooler water. The limit of the temperature control is then given by the possible formation of condensation on the surface of the rolls.
  • the card shown in its basic structure consists of a support table 1 with an assigned feed roller 2.
  • the feed roller 2 receives the thermoplastic fibers 3 fed to the support table 1 and transfers them to a pair of preliminary rollers 4, which feed the fibers 3 to a main roller 5.
  • turner 6 and worker 7 are arranged, which produce a fleece when the fibers are oriented in the longitudinal direction.
  • the main roller 5 is a tangled roller pair 8 downstream, which removes the fleece from the main roller 5 and feeds a pair of customer rollers 9.
  • a pair of press rolls 10 for consolidating the nonwoven 11 produced is located behind the pair of take-off rolls 9.
  • All rollers are equipped with a set consisting of a flat wire with a tooth shape suitable for the respective function, which is mounted on the corresponding roller so that the entire roller surface is covered with teeth.
  • the directions of rotation of the individual rollers are indicated by arrows in the drawing.
  • At least the most thermally loaded rollers e.g. the main roller 5 and the tangled roller pair 8 are formed as tempering rollers which have channels through which a tempering agent flows. These channels are not shown in detail, they are arranged in the area of the roll shell and extend essentially over the entire length of a roll, so that the roll temperature is kept constant.
  • a temperature sensor (not shown) is provided as the actual value transmitter of a regulation for the temperature of the temperature control agent and / or the roller.
  • the control ensures that a uniform roller temperature is maintained, so that no temperature distribution is formed over the length of the roller can and the roller temperature remains at the set value under all operating conditions. In particular, this maintains the exact cylindrical shape of the rollers and the set nips do not change during operation.
  • the tempering agent is a heating medium with which the desired roller temperature is set.
  • the temperature control medium is a coolant that dissipates the heat generated.
