Definitions

  • DE2321762 (henceforth DE'762) was in 1973 in the name of the company Braschler & Cie. and relates to a device for mixing yarns.
  • the device described in DE'762 is due to the same inventor of the invention disclosed below.
  • DE'762 is directed to a device for mixing roving for the production of fancy yarns which does not require a continuous roving. All rovings can be varied equally and it is possible to work with more than two rovings.
  • roving is withdrawn via deflections from a roving roll and fed to a pair of abutting belts driven pulleys and tensioned by belt guides.
  • a pair of delivery rollers which receive the stretched roving emerging between the belts and convey a spinning triangle located behind the delivery rollers.
  • the fibers of the roving which until then have been oriented approximately parallel and stretched against one another, are twisted into a yarn by a metal ring (rotor) rotating on a circular path (ring) about a spindle.
  • the twisted yarn to the yarn are wound onto a plugged onto the spindle spinning sleeve to a cop.
  • the fibers originating from the drafting system form the actual yarn.
  • the belts and the delivery rollers of the drafting system have different conveying speeds, the fibers of the roving are pulled apart uniformly, respectively stretched.
  • the absolute and the relative conveying speed of the individual areas of the drafting system are influenced so that a discontinuous conveying of the fibers results and thickening in the yarn occurs.
  • the fiber supply is never switched off completely, otherwise the spinning process suffers an interruption.
  • An effect yarn according to the invention essentially comprises two or more twisted carrier yarns having the same or different properties.
  • the effect yarn comprises other fibers which are fed between the carrier yarns by means of a drafting system prior to twisting them. These further fibers have a uniform distribution in the longitudinal direction or are present in the form of local thickenings (flames). Further combinations are possible.
  • the supply of the additional fibers is preferably controlled by means of a modified flame-forming device of a ring spinning machine.
  • one or more carrying devices are provided approximately above each drafting system of a ring spinning machine, which are suitable for receiving yarn packages with carrier yarn.
  • the carrying devices are arranged so that they do not conflict with existing elements of the spinning device, in particular the Wanderbläser and the roving bobbins.
  • At least two carrier yarns are each fed to a drafting system in the region of the spinning triangle controlled by means of thread guides.
  • two or more carrier yarns are wound on the yarn packages, which reduces the number of carrier yarn packages required per spinning station to one.
  • over or juxtaposed spools of thread can be provided with only one carrier yarn, but this is associated with a certain overhead and increased space requirements.
  • the fibers supplied by the drafting system In contrast to conventional ring spun yarns, the fibers supplied by the drafting system generally have no supporting function and are replaced in their function by the carrier yarns in whole or in part.
  • the supplied from the drafting fiber fibers are rather for the production of effects, eg optical type in the form of thickening or for the production of color variations, or for influencing the physical properties of the resulting yarns.

An impairment of the Wanderbläsers can be avoided. Another advantage is that these components can be installed in this way easily in existing spinning machines without having to be massively changed.
  • Guide separators position the applied feed bobbins in the longitudinal direction of the carrier cylinder and enable a non-contact parking position relative to the carrier cylinder (s).
  • one or more carrier cylinders (feed cylinders) positively driven in an adjustable relationship to the delivery rollers of the drafting system carry the carrier yarn packages.
  • the carrier yarn bobbins (feed bobbins) lie along a lateral surface at least in regions directly on at least one carrier cylinder or are in operative connection therewith.

Depending on the machine type, there are the possibilities of designing the carrier cylinder or cylinders so that they extend only over certain areas or over the entire length of the spinning machine.
  • a further aspect consists in an active monitoring of the carrier yarns by means of a yarn monitoring system, which is preferably arranged in front of the delivery cylinder.
  • the thread monitoring system checks whether all necessary for the spinning process carrier yarns are effectively present. If one of the carrier yarns is missing, it leads to a discontinuation of the spinning process, for example by also controlling the supply of the remaining carrier yarns in a controlled manner or by means of a drive of the supply reel.
  • a thread monitoring system usually includes a thread sensor and a thread separating device which cooperates between the supply spool and the delivery roller of the carrier cylinder with the carrier yarns. The position is preferably synchronized with the fiber material flow in such a way that the integration of the fiber material supplied by means of the drafting system of the spinning machine is optimized, eg to form a flame.
