Definitions

  • the invention relates to a sawtooth wire for production a sawtooth all-steel set for processing Textile fibers, in particular for the production of a sawtooth all-steel set for the customer of a carding machine with a plurality of one behind the other in the longitudinal direction of the wire arranged teeth, each one starting from a tooth base extending towards a tooth tip Toothbrush and one starting from the tip of the tooth towards tooth back extending to the following tooth base.
  • a carding machine is used in the manufacture of yarns for aligning and cleaning the textile fibers forming the yarns used.
  • a so-called drum acts it is a roller-shaped element, which on its outer surface with a tick set or sawtooth all-steel set is provided and is rotated about the roller axis.
  • the Drum set together with over the surface of the Tambours arranged flat bars in the course of Rotation of the spool aligns and cleans the feed Textile fibers.
  • the so obtained Nonwoven fabric with the help of so-called pickup rollers from the Drum removed and sent for further processing.
  • the pickup rollers in the area of their lateral surface also a sawtooth all-steel set on the Course of the rotation of the take-off rollers in that of the drum entrained fiber fleece engages and this from the drum subtracts.
  • the saw teeth of the saw tooth all-steel sets of the take-off rollers to be provided with grooved grooves on the side.
  • The can, for example, by a cold forming process in the course the wire production take place, whereby the saw teeth already provided with the grooved sheet sections of a wire are punched.
  • these grooved rolls is also made of natural fine-titer fibers and synthetic polymers have greater adhesion to the Tooth flank reached. This will transfer the nonwoven positively influenced by the reel on the take-off roller, that the transfer takes place faster and one otherwise possible filling of the drum set is avoided. Further it has been shown that these lateral grooves due to the greater adhesion of the fibers on the tooth flank an early solution of the nonwoven from inhibit the take-off roller.
  • the present invention has for its object a sawtooth wire to provide the manufacture of a sawtooth all-steel set for the customer of a carding machine, with an early solution of the nonwoven reliably can be avoided.
  • this task is achieved through further training the known sawtooth wires solved, which essentially is characterized in that the tooth back at least one of the teeth of the sawtooth wire at least one in the direction merging into a concave section on the tooth base has convex section.
  • concave section is used Section of the tooth back designated, its successive Points only through straight lines running outside the saw teeth can be connected to each other while by the Expression of convex section denotes such marginal courses the successive points of which are within the Straight lines of tooth flanks are connected to each other can.
  • this abutment is also thought of, this abutment to be provided by an indentation in the course of the tooth back, where a concave section between two convex Sections of the tooth back is arranged, it has proven to be proven particularly favorable if this abutment by a Projection or a cam in the area of the tooth back in which a vertex of the projection or the convex portion of the cam between two concaves Sections is arranged.
  • a particularly high retention force can be achieved if the back of the tooth preserves at least one of the teeth a number of successive in the course of the tooth back Indentations and / or projections or cams a plurality of each convex into a concave section Has sections.
  • both the concave section and the convex section in the form of polygons made of straight lines Edge sections can be provided, it has themselves with a view to obtaining a satisfactory Retention force while ensuring a gentle Intervention in the nonwoven fabric has proven to be particularly favorable, if the concave section and / or the convex section a curved course with a radius of curvature in Range from 0.05 to 0.4 mm, preferably 0.1 mm to 0.3 mm, particularly preferably has about 0.2 mm.
  • saw teeth designed in this way a particularly reliable removal of the nonwoven from the drum.
  • the invention Training the saw teeth with the known provision of grooving in the area of the tooth flanks combined be, so that at least one approximately parallel to the longitudinal direction at least one tooth flank of the wire the teeth are profiled.
  • This profiling can at least one extending approximately in the longitudinal direction of the wire Profile groove and / or at least one approximately in the longitudinal direction of the wire extending profile web.
  • sawtooth wires made of textile fibers are manufactured that a starting material to a sheet section wire is formed and then saw teeth in the sheet section are punched.
  • Sawtooth wires can be punched through at least one of the saw teeth has a tooth back with at least one towards the tooth base in a concave section transition convex section are formed.
  • at least one flank of the leaf section deformation of the raw material, such as cold working with a profile, such as at least one groove running parallel to the longitudinal direction of the wire and / or at least one parallel to the longitudinal direction of the wire extending web are provided.
  • the sawtooth wire 10 shown in Fig. 1a comprises a foot portion 12 and a leaf portion 14 less Width 14.
  • the total height H of this sawtooth wire is 4 mm.
  • In the sheet section 14 are a number of in the longitudinal direction of the wire teeth 20 arranged one behind the other are punched. Each of these teeth 20 has one starting from a tooth base 21 extending to a tooth tip 26 Toothed breast 22 and one starting from the tooth tip 26 tooth back 24 extending to the next tooth base 21 on.
  • the distance d between successive teeth is 1.96 mm.
  • the tooth incision depth h is 2.2 mm.
  • the term tooth base used above denotes the place of the deepest incision between successive Teeth 20.
  • the projection adjacent to the tooth tip 26 becomes 40 from a concave surface area 28, a convex Surface area 30 and another concave surface area 32, the concave surface area 28 towards the tooth base 21 in the convex surface area 30 passes, which in turn towards the Tooth base merges into the concave surface area 33, so that the convex surface area 30 between the concaves Surface areas 28 and 32 is arranged.
  • projection 40 provides an abutment for one of a corresponding sawtooth wire formed sawtooth all-steel clothing with textile fibers ready.
  • the second projection or cam 42 is from the concave Surface area 32, another convex surface area 34 and another concave surface area 36 bounded, the concave surface area 32 in the direction on the tooth base 21 in the further convex surface area 34 passes, which in turn in the other concave Surface area 36 merges.
  • the Transition between the convex surface area 34 and the concave surface area 36 an abutment for one of corresponding sawtooth all-steel set with fibers represents.
  • the radius of curvature of the convex surface areas 30 and 34 is the concave Surface areas 28, 32 and 36 about 0.2 mm.
  • the distance a the apex of the first projection 40 from the tooth tip 26 is in the embodiment shown in the drawing of the invention 0.7 mm during the distance al between the The apex of the projections 40 and 42 is 0.53 mm. It has have shown that with these dimensions at the same time Ensuring a gentle intervention in a non-woven fabric a particularly high retention force can be provided.
  • the sawtooth wire shown in Fig. 2 corresponds to essential to the sawtooth wire already explained in FIG. 1. Therefore, to designate the individual parts this sawtooth wire uses the same reference numerals as to designate the individual parts of the shown in Fig. 1 Sawtooth wire. The only difference is in the area the tooth tips of the individual saw teeth 20 of this saw tooth wire recognizable.
  • the Radius of curvature R4 of the concave surface area 124 of FIG Toothbrush 22 is the one shown in the drawing Embodiment of the invention 1 mm, during the radius of curvature of the convex surface area 128 of the tooth back R3 Is 0.5 mm.
  • each tooth of the sawtooth wire is in the range of the tooth back with two projections or cams.
  • each tooth of the sawtooth wire is in the range of the tooth back with two projections or cams.
  • individual or all teeth have only one cam or more than two cams. Otherwise, the tooth flanks of the individual teeth also with profiles, such as profile grooves or profile bars be equipped to the fiber retention force increase.
  • the invention is also not based on the Drawing explained the exact dimensions of a sawtooth wire limited.
