  • the blade support is known to perform an oscillating back and forth basic movement pivotable about a pivot axis, a drive member via gear means with a pivot axis present in the blade support is connected.
  • the reed should also be able to e.g. when making terry towels, to change its stop position.
  • the drive for executing the basic movement of the leaf support is carried out in a known manner via an active connection with the main drive of the weaving machine.
  • the drive system consists of means for transmitting a variable speed Electric motor on the shaft of the reed supporting the reed, the motor from a controller for changing the speed is controlled.
  • the transmission of the drive power of the electric motor to the blade support shaft therefore requires a drive system, e.g. in the form of at least one coupling gear or one Eccentric gear or a belt drive.
  • the drive systems are also susceptible to wear and maintenance.
  • a weaving machine is known from DE 198 21 094 A1, the weaving reed of which of an electromagnetic linear drive in a controlled, reciprocating movement to be moved.
  • a connecting rod engages the leaf support carrying the reed.
  • the connecting rod and an electromagnet form the electromagnetic linear drive for the Leaf support or the reed.
  • Such a drive allows both the pivot angle of the blade support as desired adjust, regardless of the main drive of the loom, as well as the Blade stroke frequency can be easily adapted to the requirements.
  • the connecting rod is a critical solution as a construction element because it is connected to the leaf support requires storage that is subject to considerable wear.
  • the blade support drive should, in particular with regard to the required performance parameters Weaving machine, not restrictive, the blade support drive should be low-mass and require no additional installation space, the blade support drive should be in every phase of the Weaving process, i.e. a constant starting with the start of the weaving machine Realize the dynamism of the leaf supports, the leaf support drive should be contact points in the tissue to avoid and finally the blade support drive for weaving both smooth and also suitable for weaving terry fabrics.
  • the known shaft the leaf support of a weaving machine is part of an electromotive direct rotary drive, which has a stator and optionally an inner rotor or an outer rotor.
  • the shaft is a stator in an outer rotor with an electrically active area and one Mounting part picked up and rotatably stored in the weaving machine.
  • the reed is over one leaf bar and normally over several Blade supports are connected to the assembly part of the outer rotor by crane connection.
  • this is an electric one Servomotor or a radial electric linear motor is.
  • the drives for the blade support shaft designed as a radial linear motors are.
  • the blade support shaft is a fixed construction element.
  • the one with the Blade supports connected to blade supports are pivotable about the longitudinal center axis the blade support shaft in bearings.
  • the leaf supports are at least in one Area between the sheet bar and its storage on the blade support shaft in such a segment-like manner formed that several on one or double sides on the segment-like surfaces Permanent magnets are arranged, which according to the invention together with the blade support Form the secondary part (slide) of an electromagnetic linear motor.
  • the primary part of the linear motor is formed by coils, which are also segment-like trained and rotatably connected to the blade support shaft spool are, according to the position of the permanent magnets of the secondary part.
  • the primary and secondary parts positioned relative to one another each form a disc armature motor.
  • To record and report the angular positions of the leaf supports within a predetermined limit angle range is at least one of the drives with a resolver equipped with the electronic control unit of the weaving machine connected is.
  • the advantage is that the dynamics of the reed are already there when the weaving machine is started is achieved as it is required in the continuously running weaving process.
  • the blade support shaft 4 of a weaving machine is included as a stator Coils 5 formed.
  • the direct rotation drive is e.g. an electric servo motor.
  • the external rotor of the direct rotary drive 1 is received by a magnet 6 Carrier ring 7 formed.
  • the leaf support 2 is through Connecting means 24 connected to the carrier ring 7.
  • a leaf bar 9 anchored to the leaf support 2 carries the reed 3.
  • the reed 3 with the leaf bar 9 and the leaf support 2 is located in a position in which at least one in a shed 11 formed from warp threads 10 Weft thread 12 is entered.
  • leaf bar 9 and Sheet support 2 is the weft thread 12 against the stop edge 13A of the fabric 13 struck.
  • the striking movement of the reed 3 for the purpose of striking the weft thread 12 to the stop edge 13A of the fabric 13 takes place according to the invention in that the Carrier ring 7 as the rotor of the electromotive direct rotary drive 1, the blade support 2 together with the reed oscillating from the given rear end position in the stop position and pivoted back, in the direction of the double arrow 14.
  • the assembly of the blade support 2 at a certain pivot angle ⁇ 1 to the vertical determines the basic position of the reed 3. Based on this, it is according to the invention possible, an oscillation angle ⁇ 2 of the reed by appropriate control of the Direct drive 1 to vary accordingly, such as terry weaving is required.
  • FIG. 2 shows an electromotive direct rotary drive 1 in which the function of Stator and rotor are interchanged.
  • the blade support shaft 4 is designed here as an inner rotor.
  • a plurality of magnets 6 is arranged, the with coils 5 of the stator carried by a machine-fixed bracket 15 work together.
  • Figure 3 shows the direct rotary drive 1 acc. Figure 2 in plan view.
