Definitions

  • the invention relates to a sewing machine needle and a sewing method. Sewing machine needles and sewing methods are known in different variants.
  • the EP1052324A2 shows an initially flat groove, which is rounded in order to prevent sharp edges in the groove damage the fabric.
  • the result is a groove geometry on average, which has no or a very large rounding radius in the vicinity of the needle center. In the vicinity of the side edges is a significantly smaller radius of curvature, resulting in even clear side surfaces with an orientation parallel to a line 9 in the eye direction.
  • the US3589428A shows a manufacturing method for a sewing needle, in which a flattened area is prepared before the introduction of the channel.
  • the illustrated needle has no groove.
  • the DE3027534A1 shows a sewing needle, in which the shaft is offset parallel in the region of the groove compared to the rest of the shaft region. By this offset creates a groove, in which the space between the sewing thread and needle is increased. As a result, the loop recording is simplified by a gripper. Due to the offset of the shank, when the needle retracts, an additional load on the material is created by the transition to the offset area of the shank.
  • the cross-sectional area of the needle in the offset area corresponds to the cross-sectional area of the needle in the adjacent shaft or is only slightly reduced. Identical solutions and similar differences to the present invention are in US4458614A and EP1052323A2 shown.
  • the DE69220550T3 shows a manufacturing method for a sewing machine needle, which produces a sewing needle as a result, in which the groove has a reduced width.
  • the needle should have an improved penetration resistance.
  • Object of the present invention is to provide a sewing machine needle, which has an increased reliability during sewing.
  • Another object of the present invention is a sewing method that is less susceptible to interference.
  • the object is achieved by a sewing machine needle according to claim 1 and a sewing method according to claim 9.
  • the sewing machine needle according to the invention generally has at one of its two ends in the longitudinal direction of a needle piston, with which the sewing machine needle is clamped in a sewing machine. Through the center axis of the usually cylindrical needle piston, the center axis of the sewing machine needle is defined. At the other end of the sewing machine needle in the longitudinal direction of a tip is formed, with which the needle pierces the sewing material during sewing. Directly adjacent to the top is the eye into which the suture thread has entered. Between the eye and the needle piston extends the needle shaft, which accounts for a large part of the length of the sewing machine needle. Transition areas can each be located between the aforementioned areas.
  • the eye essentially passes through the needle in one direction, which is called height direction.
  • the height direction is perpendicular to the longitudinal direction of the sewing machine needle.
  • the longitudinal direction points from the rear needle piston to the tip at the front end of the sewing machine needle.
  • the longitudinal direction is usually parallel to the central axis.
  • the direction perpendicular to the two aforementioned directions is referred to as the width direction.
  • the eye In the area of the needle shaft, the eye is longitudinally preceded by a groove.
  • the contour of the groove jumps back in the height direction with respect to the contour of the needle shaft.
  • the height direction thus points from the middle of the needle over the groove to the outside in such a way that the values continue to grow outside the groove.
  • a recessed area on a sewing machine needle is designated, which is adapted to provide an engagement space for a gripper, in which the sewing thread is not applied directly to the needle, because there are adjacent areas on the shaft and the eye, in the height direction on the groove lie.
  • the groove extends from the immediate vicinity of the eye over a portion of the longitudinal extent of the needle shaft.
  • the sewing machine needle has in the region of the groove in a sectional plane perpendicular to the longitudinal direction or in all cutting planes in the region of the groove - except transition areas - a substantially circular arc-shaped contour.
  • a substantially circular arc-shaped contour directly adjacent to an axis of symmetry which runs in the sectional plane through the central axis of the needle and in the vertical direction, there are no straight, flat sections, but it extends in both orientations of the width direction from the center of the groove starting an at least approximately circular arc-shaped contour path.
  • at least no distinct plateau is formed in this cutting plane at the location farthest from the central axis of the needle in the height direction.
  • Deviations from the circular shape are permissible inasmuch as due to these deviations in order to comply with the geometrical conditions with regard to heights and widths necessary for the sewing process, no kinks or sharp edges occur in the groove.
  • the circular-arc-shaped region of the contour of the groove covers a first angle section of the needle circumference.
  • the first angle section preferably extends on both sides of an axis of symmetry which is defined in the sectional plane by the center axis of the sewing machine needle and the height direction. At this first angle section can connect more angular ranges that complete the contour of the fillet.
  • the contour of the groove or the sum of angles of the angular ranges, from which the contour of the groove is formed covers half, ie 180 °, of the entire circumference of the needle.
  • the vertex of the angular ranges is determined by the intersection of the axis of symmetry, which lies in the height direction, with a distance in Widthwise direction and is located at the point of maximum extension of the needle in the width direction in the region of the groove.
  • the radius of curvature of the substantially circular arc-shaped contour of the needle in the region of the groove is for example about 50% of the maximum extent of the needle in the region of the groove in the width direction and is between 45% and 60% of the maximum extension of the needle in the region of the groove in the width direction.
  • This special choice of the radius of curvature creates a shape of the groove, which is particularly well suited for a secure takeover of the sewing thread by a gripper element.
  • Grippers are usually adjusted during sewing so that the sewing machine needle and gripper do not touch each other. Due to the return stroke of the sewing machine needle, the sewing thread forms a loop which the gripper can take up in interaction with the groove.
  • the gripper performs at least temporarily a movement that also contains components in the width direction of the sewing machine needle and with which the gripper of the sewing machine needle also approaches in the width direction. For example, due to vibrations in the sewing machine, heavy thread tension, poor setting of the sewing machine or other shortcomings, it may happen that the sewing machine needle and the gripper touch each other. If the groove is at a uniform level in the height direction, the gripper beats in such a case against a standing at least approximately perpendicular to the direction of movement of the gripper side surface of the sewing machine needle, which inevitably has a groove with plateau. As a result of such striking, damage to the sewing machine needle and / or the gripper may occur in addition to sewing errors. Due to the inventive contour of the groove, the sewing machine needle in the region of its groove offers the gripper in the event of contact surface areas, which have an angular position, which preferably divert the gripper in the right direction and avoid a dull clashing.
  • the essentially circular-arc-shaped contour of the needle in the region of the groove can extend at least over an angular range of 90 °.
  • the radius can cover an angle range of at least 100 °.
  • the radius can cover an angle range of at least 110 °.
  • the maximum extent of the contour of the needle in the region of the groove in the height direction can preferably amount to a maximum of 65% of the maximum extent of the contour of the needle in the region of the groove in the width direction.
  • the maximum height of the needle can be measured between two parallels to the width direction, when the first touches the two gutter edges tangentially and the second tangent to the groove.
  • the maximum height of the needle in the fillet can be between 60% and 70% of its maximum width in the fillet.
  • the maximum height of the needle in the groove is between 55% and 75% of its maximum width in the groove.
  • the needle can reach its maximum extent in the width direction in the region of the groove, preferably below a central axis, in particular at 32% of its maximum extent in the height direction measured from the side facing away from the groove.
  • the maximum width of the needle can be reached between 30% and 35% of the height.
  • the maximum width of the needle can be reached between 25% and 40% of the height.
  • the cross-sectional area of the needle in the region of the extension of the groove in the longitudinal direction of the sewing machine needle may be 70% of the smallest cross-sectional area perpendicular to the longitudinal direction in the region of the remaining needle shaft.
  • the cross-sectional area in the groove may be between 65% and 75% of the cross-sectional area of the remaining needle shank.
  • the cross-sectional area in the groove is between 60% and 80% of the cross-sectional area of the remaining needle shank. Due to the appropriately selected cross-sectional area in the area of the groove, the demands on the strength of the needle and the requirements on the geometry of the needle, which can be used for a safe sewing process and are necessary for the protection of the sewing material, coordinated and optimized.
  • the needle according to the invention may have a constant cross-sectional area in partial sections of the course of the longitudinal extent of the needle shaft or may be tapered at least in sections in the direction of the needle tip. Such a taper can then be designed in such a way that the contour is retained in the shape and is continuously scaled by only one factor during the course of the longitudinal extension.
  • a tapered portion may be present in the region of the groove and / or in the course of the remaining needle shaft.
  • the largest cross-sectional area of the groove at its end towards the remainder of the shank may preferably be 65% of the smallest cross-sectional area of the shank at its end towards the groove ,
  • the maximum extent of the needle in the region of the groove in the width direction can correspond substantially to the maximum extension of the needle in the region of the remaining shaft.
  • the needle shaft has a long groove which extends substantially in the longitudinal direction of the needle.
  • the groove and the long groove are located on opposite sides of the needle shaft with respect to the height direction.
  • the long groove preferably extends substantially over the entire longitudinal extent of the needle shaft from the transition to the needle piston to the eye.
  • the long channel runs advantageously over its entire extent in the longitudinal direction and in particular in the region of the groove substantially parallel and at a constant distance from the central axis of the sewing machine needle. This design is again gentle on the sewing material. Long troughs serve to protect the sewing thread when piercing the sewing material. In principle, this function is also fulfilled by long channels, which have different distances to the central axis over their longitudinal extent.
  • Such elongated troughs then have transitional areas between the longitudinal sections of the elongated troughs located at different heights, which can damage the sewing material during insertion or even during retraction.
  • it should be interpreted essentially parallel and at a constant distance from the central axis so that the groove edges can be slightly lowered in the region of the groove inwards, which can then apply correspondingly to the groove bottom.
  • the channel bottom in the region of the groove can also be raised slightly in relation to the channel bottom in the region of the remaining shaft.
  • the deviation of the channel that is the channel edge and / or the channel bottom, from the parallelism of the central axis or the deviation of the distance of the channel edges and / or channel bottom to the central axis in the region of the groove to the remaining shaft is then a maximum of 10% of a mean width of the shaft.
  • the deviation of the groove from the parallelism or the deviation of the distance of the groove from the central axis can amount to a maximum of 5% of a mean width of the shank.
  • the deviation of the groove from the parallelism or the deviation of the distance of the groove from the central axis can amount to a maximum of 2% of a mean width of the shank.
  • the shaft may have a groove in the longitudinal direction following the groove. This channel is often called a short channel.
  • the short groove can reach from the groove to the piston. Between the groove and the short groove, a region raised in relation to the groove can also be present. As described earlier, such a raised area serves to allow the thread in the groove to be well received by a gripper member. All embodiments of a sewing needle according to the invention may have such a short groove.
  • the contour of the needle in the region of the longitudinal extent of the groove in the cross-sectional view, which results in a section perpendicular to the longitudinal extent of the needle, in addition to the first angle portion have at least a second angle portion which extends straight and a third angle portion, the connects the first and the second angle section.
  • the third section connects the other two sections kink-free.
  • the straight section is preferably made short and preferably present on both sides in the width direction.
  • the straight section can be at an angle of 18 ° to the vertical direction.
  • the straight section can be at an angle of 15 ° to 21 ° to the height direction.
  • the straight section can be at an angle of 12 ° to 24 ° to the vertical direction.
  • the third angle section leads the radius of curvature of the first angle section tangentially without kinks into the straight section of the second angle section.
  • At least the contour of the third angular region that is to say the transition between the first and second angular region, has an angular position with respect to a possibly impinging gripper, which makes it possible for both parts, despite contact, to continue the sewing process without damage.
  • the angle of the straight section which sweeps over the second angle section in the region of the groove, can be made variable in the further course in the region of the shaft.
  • the angle may increase in the direction of the needle piston, for example from 30 ° to 36 °.
  • the increase of the angle can also be done by a different amount, as well as the angle of the shaft adjacent to the groove may have an amount other than 30 °, depending on how the groove is designed.
  • the sewing machine needle can be embodied in the region of the extension of the groove in the longitudinal extension of the needle in the sectional plane perpendicular to the longitudinal direction with mirror symmetry to an axis of symmetry which is defined by the height direction and the central axis.
  • the sewing machine needle can be used both in sewing machines, in which the gripper from the left as well as in sewing machines, in which the gripper engages from the right side of the needle into the groove.
  • the needle can thus be used in machines or applications in which a chamfer is required in the groove.
