Definitions

  • the invention relates to a needle, in particular for Large embroidery machines, with a plunger and one on the Piston adjoining shaft that ends in a tip and in which at least one groove and one eye are formed are, one on the shaft near the piston A predetermined breaking point is provided.
  • the object of the invention is therefore a needle especially for large embroidery machines (Schiffli machines and the like), which is characterized by a high Resistance to side loads distinguished and it is ensured that they nevertheless in case of overload at a predetermined point near the piston breaks.
  • the above is Needle according to the invention characterized in that the An all-round rounded shaft near the piston Constriction has that on the constriction a conical tapering towards the tip Connects shaft area that into a cylindrical Shaft area merges and that the constriction at the edge towards the piston and the conical shaft area is rounded to form smooth transitions.
  • the constriction can advantageously be on the ground Have diameter that is approximately equal to that Diameter of the cylindrical shaft part is, it can but also slightly larger or smaller than this Diameter measure. It is in the bottom area in the Profile generally in the shape of a circular arc rounded and expediently has a substantially V-shaped profile on the edge of the transition rounded to the piston and to the conical shaft area is.
  • This conical shaft area has one relatively weak taper; his cone angle is advantageously between about 0.5 ° and 2 °.
  • the length of the conical shaft area depends on the needle construction and is often between 10% and 50% of the total Shaft length.
  • the needle shown in the drawing is special intended for large embroidery machines (Schiffli machines), can also be used for other embroidery machines, for sewing machines and the like are used. It is made of steel and has a substantially cylindrical piston 1 to which a shaft 2 connects, which is in a Tip 3 ends. In the shaft 2 is an axially parallel Long groove 30 is formed, which leads to an eye 4 that a top channel 5 connects.
  • the constriction 6 is, as in particular from FIG. 3 to be seen in profile essentially V-shaped, being in the base region 9 in the form of a circular arc is rounded out, which is shown in FIG. 3 by a radius 10 is indicated.
  • the constriction 6 is on the edge Piston 1 and rounded toward the conical area 7, so that there are smooth transitions at 11 and 12.
  • the angle the two of the floor area 9th outgoing conical walls of the constriction 6 with each other limit is on both sides of the floor area 9 indicated in Fig. 2 at 13 and 14, respectively.
  • the angle 13 on the piston side is approximately 20 to 30 °, preferably about 25 ° while the size of the conical area 7 adjacent angle 14 is between about 10 and 15 °.
  • the diameter of the constriction 6 at the bottom 9 thereof is approximately equal to the diameter of the cylindrical Shank area 8 and indicated in Fig. 3 at 15.
  • the cone angle of the conical area 7 is in the Order of magnitude of approximately 0.5 to 2 ° and is 16 in FIG. 2 indicated.
  • the length of the conical area 7, which is about to the line 17 shown in FIGS. 1, 2, is approximately between 10 and 50%, preferably approximately 30% the entire length of the shaft measured from the end of the Piston 1 at 18 to the end of tip 3.
  • the constriction 6 forms a predetermined breaking point in the immediate vicinity of the piston 1. Along with that on but the conical region 7 that follows them leads to no loss of stability of the needle compared to comparable Conventional needles; rather, it results rather an increase in the resistance of the needle against lateral loads, taking the needle overall characterized by high fatigue strength.
