Fig. 5 is the view that is similar to Fig. 2 that has the embodiment of two drive motors.

The specific embodiment

The terry cloth loom that schematically shows in Fig. 1 has: have ground warp 11 through axle 10 and have pile warp 13 through axle 12.Ground warp 11 is diverted and enters substantially horizontal woven flat via leaning against 14.Pile warp 13 be preferably move on the flexible deflector 15 it self lean against 16, and same from here operation enters woven flat.Ground warp 11 and pile warp 13 march to the shedding motion 17 with the arrow indication.In the upstream of deflector 15 deflector 47 is housed.

Weft yarn is inserted into shed open in occasion separately.The device that is used to insert weft yarn can adopt air-jet loom for example to insert the form of device.This device generally has: two main jets blow nozzle, and they fitted to be one and are positioned at after another, and next-door neighbour's shed open; And row's relay nozzle, they are assembled on the slay 18, and the weft yarn of the directed reed 19 of their blowing direction inserts passage.Be formed for the beating up device of yarn of rotatable driven slay 18 reed 19 together, reed 19 takes the weft yarns that insert to beat-up line.On this beat-up line, when shed open was changed, just shedding motion 17 was converted to lower position to some warp thread from upper position, and some warp thread when lower position is converted to upper position, these weft yarns rely on warp thread to be captive.The fabric 20 that forms thus relies on extraction roller 21 to be drawn out of, and is wound onto on the cloth beam 22.Brest beams 23 and two deflectors 24,25 are assembled in the upstream of driven extraction roller 21.Brest beams 23 makes fabric 20 produce substantially horizontal woven flat downwards.Extract the form of roller 21 employing sand roller or needle beam out.

Ground warp 11 lean against 14 and brest beams 23 rely on drive units 26 in woven flat, to be moved back and forth substantially along same direction.For example, 16 modes of submitting to elasticity that lean against of pile warp 13 are remained in the woven flat substantially.By leaning against 14 and the reciprocating motion of brest beams 23, the warp thread of ground warp 11 and pile warp 13 and the fabric that is made into 20 are similarly moved back and forth, thereby make distance between the beat-up line of fell 27 and reed 19, just slay 18 is shifted to the variable in distance of this circuit towards the direction of fell 27 during the beating up of weft yarn.The measure that fell 27 is taked is: for example, at weft yarn after the beating up of described fell 27, by make lean against 14 and brest beams 23 correspondingly move to the left side among Fig. 1 just, this fell is removed from beat-up line.Lean against 14 and brest beams 23 and therefore this position of fell 27 for example be maintained at its ensuing two to four wefting insertion and beat up during in.Then by make lean against 14 and brest beams 23 correspondingly move to the right among Fig. 1 just, fabric 20 and fell 27 are retracted together near reed 19.When being beaten up on weft yarn this position at fabric 20 of last insertion, described weft yarn is brought on the fell 27 with the weft yarn of previous insertion.In process of production, weft yarn slides along the warp thread of the ground warp 11 tight than anxiety.The warp thread of the pile warp 13 of less tensioning is taken away by weft yarn when beating motion, thereby makes the warp thread of pile warp 13 be formed pile loop, and this pile loop protrudes up and/or down from the surface that comprises ground warp 11 and weft yarn.

Leaning against of ground warp 11 14 is installed on the rotating lever 28, and this swingle thick stick can lean against 14 axle 29 and is rotated about being parallel to.Axle 29 carries the roller-shaped deflector of the warp thread that is used for ground warp 11, and this warp thread marches to and leans against 14.Being connected on the rotating lever 28 is lever 42, and it is kept by spring 43.Lever 42 is formed for 14 the holding element of leaning against of ground warp 11.Rotating lever 30 is formed for the holding element of brest beams 23, and can be rotated about the axle of deflector 24, and this axle is parallel to brest beams 23 and extends.

Rotating

lever

28 and 30 relies on drive motors 31 to be driven, more precisely stepper motor.Drive motors 31 is connected on the axle 33 via speed reduction gearing 32, and this axle is parallel to and leans against 14 and brest beams 23 extensions.Speed reduction gearing 32 has the input coaxial with its output, thereby makes that drive motors 31 and axle 33 are coaxial mutually equally.Axle 33 relies on bearing element 34 to be mounted, and this bearing element can be connected on the unshowned side part of loom frame.The outer cover of transmission device 32 is connected on one of bearing element 34.

Two turning arms 36 are connected for and axle 33 rotation together, and described turning arm is assembled on the axle 33 on the spacing corresponding to fabric width.A pair of drive link 37 is connected on the turning arm 36, and described bar is connected to carrying and leans against on 14 the rotating lever 28.Turning arm 36 also is connected on the rotating lever 30 of brest beams 23 via a pair of drive link 38.Drive link 38 has the profile of the arciform bending that makes progress, thereby makes the zone of fell 27 of fabric 20 freely to enter.In this zone, auxiliary unit is housed by convention in addition, for example as the shearing device that is used for weft yarn, selvedge folding device and temple.

Shown in Fig. 1 and Fig. 2 are clear, lead to the drive link 37 that leans against 14 rotating lever 28 and compare with the drive link 38 of the rotating lever 30 that leads to brest beams 23 and be assembled on the less radius distance of axle 33.

The speed reduction gearing 32 that is assemblied between drive motors 31 and the axle 33 does not have self-lock ability, and only comprises about being parallel to the rotatable gear of axis of axle 33.Act on lean against 14 and brest beams 23 on the effect that has of power be: drive

link

37,38 and rotating

lever

28,30 adopt the centre position between the final position together all the time, just fell 27 at the position of the most close reed 19 and fell 27 away from the position between the position of reed 19 and beat-up line.

The power that the size of independent component and geometrical arrangements make to produce allows the poised state that enters quite big degree each other, thereby makes and be under the situation of zero current at drive motors, and above-mentioned centre position is kept.Shown in legend is clear, drive link 38 for example be assembled in for this reason compare from the bigger distance of the axis of axle 33 with drive link 37 last.Do not have to act on by the restoring force that drive motors 31 overcomes on rotating

lever

28,30 and drive

link

37,38 and the axle 33.Therefore drive motors 31 need only apply less power so that obtain high braiding speed.The equilibrant force that permission stops in the centre position also causes satisfied efficient and corresponding low energy consumption except the braiding speed that promotes.

Drive motors 31 is free programmable, and can realize being moved into the position of being determined by its control device, rather than determines this position by the maximum deflection that only is limiter or radial gear arbitrarily.Maximum position is determined by the control device of drive motors 31 separately.This makes and might even changes cloth fell that when braiding for example so that weave the zone that has big pile loop, braiding has the zone of less pile loop or weaves the zone that does not have pile loop and only have flat fabric.Also might be from fell 27 a distance, rather than when braiding, change the order of beating up from fell 27 a distance.

In the exemplary embodiments according to Fig. 3, the deflector 15 that leans against 16 upstream that is assemblied in pile warp 13 can rely on transmission device 26 to be moved back and forth equally.For this reason, a pair of in addition drive link 39 is connected on the turning arm 36.Drive link 39 acts on a pair of double-arm lever 44, and this double-arm lever is rotatable about coaxial axle 45.Second arm of lever 44 comprises bearing 46, and it keeps the deflector 15 of pile warp 13.Double-arm lever 44 is driven by drive link 39, thus make by this way deflector 15 towards with lean against 14 and the opposite direction of brest beams 23 move, be moved to the left if just lean against with brest beams, deflector 15 just moves right, and vice versa.Be equipped with between double-arm lever 44 and drive link 39 and adjust element 67, the amplitude of feasible like this route of being advanced by deflector 15 can be adjusted with respect to the angular movement of turning arm 36.Deflector 15 is flexible, and is such just as already mentioned.It has carrier bar 64, is essentially columniform steel spring plate 65 and is connected on this carrier bar by Connection Element 66, and this Connection Element for example is a screw.

One embodiment of the present of invention propose leaning against of

pile warp

13 and 16 are kept by elasticity, make this lean against like this and can be moved into woven flat basically.Such retainer 53 comprises for example support 56, and it is kept by sheet spring assembly 57, is that 102005028127.3 German patent application is described the same with similar international application no.What another embodiment proposed that transmission device 26 also moves back and forth pile warp 13 leans against 16., be similar to as the legend among Fig. 3, so a pair of in addition drive link is connected on the turning arm 36, described bar acts directly on leaning against on 16 of pile warp 13 or keeps leaning against on 16 the rotating lever for this reason.

Drive motors 31 can be by controlled each wefting insertion that is used for of program, and this not only sports amplitude, and beginning and end about moving in weaving cycle.For drive motors 31 only responsive be the position that it will adopt regulation when weft yarn is beaten up.During the remainder of weaving cycle, drive motors 31 can adopt the optional position in principle.In preferred configuration, the measure that the motion of drive motors 31 is taked is: before arriving stop position, locate beginning for 120 ° that are similar at loom main shaft.Drive motors 31 can rotate then through for example 60 angles, thereby makes axle 33 be rotated through for example 16 angles via speed reduction gearing 32.These angle values are certainly taked other values, and for example drive motors 31 can rotate through the rotation of 600 angles with 20 angles of acquisition axle 33.The amplitude of the angular movement of drive motors is that the basis is determined with desired pile height basically.The motion outline of drive motors 31 is that the basis is determined basically with the loom speed.For example, axle 33 can be moved between 0 and 16 angles, so that realize the pile height between 0mm and the 20mm.This angle value certainly can be selected and can be taked other values.

Fig. 4 illustrates the embodiment of transmission device 26, and wherein drive

link

37,38 and/or the turning arm 36 on two sides of machine is rigidly connected with being expanded, thereby makes that connecting axle 33 (Fig. 2) can be save.Turning arm 36 is assembled coaxially with axis 51, and this turning arm is assembled on the spacing that is suitable for fabric width.They are joined together by connecting rod 52, thereby make the motion of drive motors 31 be sent to the turning arm 36 on opposite.Replace connecting rod 52 or selectively except connecting rod 52, for a

rotation bar
