- the shape of the teeth and the pitch of the teeth so produced Sawtooth wire depends on the position of the base plate 444 with respect to the machine bed 400 or the feed device 410, the punching tool used and that of the screw edge 416 cooperating with the gear wheel rotatable about the axis of rotation 420 produced gear reduction.
- a similar device is described in FR 2 435 540 A.
- Type sawtooth wires for machining Textile fibers are used especially at high processing speeds increased staple fiber damage and accumulations of disorderly Fibers, especially short fibers (pilling effect) observed.
- From GB 2 258 471 A are for the production of trimmings Saw tooth wires intended for the cover of a card, at which the distance between the tooth tips of two successive Teeth of the one between the tooth tips of others of successive teeth.
- the invention has for its object a method specify for the production of such sawtooth wires, and a to provide operable device for performing this method. This object is achieved by what is stated in claim 1 Method and the device specified in claim 4 solved. Preferred embodiments of the invention are in the dependent Claims specified.
- the desired one For example, this achieves the pitch of sawtooth wires between saw teeth of the same shape, e.g. in Pointed shape, curved tooth shape or flat pointed shape material-free spaces of different shapes.
- this purpose for example thought of material-free spaces between two consecutive Teeth by a number of successively executed Machining operations with a machining tool, in particular Punching tool.
- the sawtooth wire but also saw teeth of different shapes e.g. in Have Morel shape, thanks to material-free spaces of the same shape are separated from each other.
- For the production of such sawtooth wires can create all material-free rooms through one machining process getting produced.
- the feed distance of the profile wire is continuously recorded and the feed device and / or the processing device controlled depending on the detected feed distance becomes.
- the feed device can be attached to the profile wire have applicable conveyor roller, the rotational position of which is continuous is detected with a second angle encoder.
- the device shown in Fig. 1 comprises one a machine bed 100 mounted feed device 110 and a processing tool also mounted on the machine bed 100 130.
- the feed device 110 consists essentially from a servo motor 112, a reduction gear 114 and a pair of feed rollers 116 between which a sawtooth wire 150 is jammed.
- a feed roller of the feed roller pair 116 is mounted directly on the axis of the reduction gear 114, so that the profile wire 150 by rotating this feed roller lengthways in the direction indicated by arrow 152 a predetermined funding path 154 is promoted.
- the processing tool 130 consists essentially of a servo motor 132 and one mounted in a headstock 134 Spindle 136, which with the servo motor 132 in the by Direction arrow 137 is driven.
- the spindle 136 has a punch tool holder 131 mounted in a rotationally fixed manner.
- a punch tool 140 is fastened to the punch tool holder 138, interacting with a punch die 142 for Production of saw teeth material-free spaces from the profile wire 150 can be punched out.
- the servo motor 132, the Headstock 134 and thus also the spindle 136 and the punch die 140 are mounted on a base plate 144, which with respect the machine bed 100 and thus also with respect to the feed device 110 is pivotable in steps of 5 °, such as indicated by the degree scale labeled 146.
- the servo motor 132 of the machining tool 130 is from a controller 160 according to a predetermined program a control line 166 is driven.
- the rotary position the spindle 136 is detected by an angle encoder 162 and passed on to the controller 160 via a line 164.
- the spindle 136 becomes the servo motor 112 of the feed device 110 from controller 160 via a control line 172 driven.
- the by the operation of the servo motor 112 of the feed device 110 produced feed section of the sawtooth wire 150 along the predetermined conveyor line 154 detected with an angle encoder 168.
- a the detected feed distance representing signal is from the angle encoder 168 via a Line 170 applied to controller 160.
- the known mechanical coupling between the spindle of the machining tool and the feed device through an electronic coupling replaced.
- This electronic coupling is done with the help of Controller 160 and the predetermined program causes, which Parallel operation of both servomotors 132 and 112, especially in the Start and stop phase is of the utmost importance.
- FIGS. 2a) to 2c) With the device shown in Fig. 1 are sawtooth wires with variable division of those in FIGS. 2a) to 2c) shown type producible.
- These sawtooth wires 10 each have a foot region 12 with a plurality of one behind the other in the longitudinal direction of the wire arranged, starting from the foot area 12 and each a tooth tip 16 having teeth 14.
- Sawtooth wires shown increases the distance between the Tooth tips of successive teeth, i.e. the tooth pitch, initially along a first wire section of predetermined length continuously to then over a second wire section the specified length continuously decrease.
- sawtooth wires with saw teeth in pointed form, curved tooth form or flat pointed form the shape of the material-free spaces 18 between the individual Teeth changed.
- the device can be used Fig. 1 for the manufacture of the individual material-free spaces 18 each a corresponding number of punching operations become.
- Fig. 3 can be produced with the device of FIG. 1 Graduation curves of sawtooth wires are shown.
- 3a) it is possible, for example, according to a predetermined one Program to generate a division course in which the distance between the tips of successive teeth along one Wire section of predetermined length ⁇ 1 starting from a first predetermined distance up to a second predetermined Distance increases continuously and then from the second predetermined distance to the first predetermined distance decreases continuously, the amount of the difference between successive distances between the tooth tips consecutive Teeth is about constant.
- the division course can also be wavy or can be designed variably.
- the invention is not based on the drawing illustrated embodiments limited. For example it is also possible to use sawtooth wires with different tooth shapes manufacture. As an alternative to that shown in FIG. 1 Operation is also contemplated to the servo motor 112 Feed device 110 to use as a master and the servo motor 132 of the processing tool 130 to be used as a slave.
