Definitions
- Felting needles and their manufacturing methods are known. Felting needles change the density of confused textile fibers. In most cases, the fibers are compacted into felted sheets. For this purpose, felting needles are hung on a suspension board (often called a "foot"), often simply in a bent part of their shank, in a needle board
- This working part which is often followed by the tip of the needle, taken.
- This working part usually has a specially shaped cross-sectional area (very often polygonal shapes, such as triangular or rectangular shapes are used). However, round shapes - such as drop shapes - are known for such cross-sectional areas. In the working part there are notches, the outer profile of the
- the needle boards perform in felt production a large number of work cycles per unit time. It is therefore not surprising that felted needles are exposed to high stress in particular by the contact with the textile fibers. Increasing the durability or service life of felting needles is therefore one of the topics that experts have been working on for a long time.
- the document US 2,678,484 B proposes to solve this problem, felt needles, which are provided with a plurality of successive in the longitudinal direction of the needle notches to be provided with a needle tip closest notch, which is less pronounced and a less pronounced
- Puncture ridge has as the offended by the top notches.
- US 2,495,926 B attempts to solve the mentioned problem in another way: by a special formation of the Einstichmeiseis there is a widening of the puncture bead, so that they can withstand the continuous friction of the textile fibers longer.
- the present invention is based on the object to increase the life of felting needles.
- the present invention proceeds from the latter document and solves the problem in each case by the feature combination of claims 1 and 8.
- Circumferential direction ( ⁇ ) of the felt needle extends and in much of the
- the notch is hereby formed by a puncture of the
- the bulge extends in the longitudinal direction (z) of the felting needle only over a partial region of the extension of the working part in this direction (z),
- the at least one bulge can already in the production of the
- the bulge at least has volume constituents which are not attributable to the puncturing bead, that is, which did not come about as a result of the volume displacement of the groove for producing the notch.
- the bulge is reinforced by the puncture bead, which is beneficial.
- the notch adjoins the outer surface of the bulge in the longitudinal direction of the felting needles. This can be done by locating in the forward direction of the needle in the felt formation before the notch
- the notch and the bulge have the same position in the circumferential direction and / or they lie on a web.
- the at least one bulge has a height which changes in the direction of the longitudinal extent of the needle, for example it is advantageous if the bulge in the plane facing away from the needle is
- the notch is removed. It is advantageous to produce the bulge by a non-machining process - such as a pressing process - or at least to make part of the preparation of the bulge with such a process. It is advantageous if the pressing tools or at least one pressing tool are moved at least predominantly in the circumferential direction and / or the radial direction of the needle. However, the at least one bulge can also already by the Anformvorgang, the
- Such advantageous minimum distances are: a) at least one distance which corresponds to the simplicity of the length of the notch opening in the longitudinal direction of the felting needle,
- Felting needle is more, which overlaps in the circumferential direction with the first notch.
- the bulge already exists (for example, already in the blank of the needle) or is formed before the notch is inserted.
- Another advantage is to position the notch so that the
- Einstichsmeisel when piercing the notch also displaces portions of the bulge, or in this way the strength of the bulge in the radial and / or circumferential direction of the needle reinforced (it forms again a puncture in the bulge in the bulge, which amplifies them). This effect can occur when the chisel is placed in the immediate vicinity of the bulge or even on the bulge itself.
- Working part is particularly far away from the needle axis. This is the case in the area of the webs or in the area of edges. If this design maxim is heeded, the at least one bulge still protrudes above the already
- the bulge is a pressed sausage, it is advantageous to produce it with at least two pressing tools.
- These two pressing tools act - at least predominantly - in the circumferential direction of the needle.
- the effective direction will also contain components in the radial direction of the needle.
- the effective direction of the two pressing tools is opposite, it being possible to move both tools by the same amount or by different amounts.
- a tool can only serve as a stop while the other or the others are moved.
- Boundary surface is provided in the radial direction of the needle. This shaping the boundary surface in the radial direction of the needle can go to a defined setting the height of the bulge. This measure is thus in all embodiments of the disclosed in this document and
- the molding can be performed with a stamp acting at least predominantly in the radial direction of the needle. At least predominantly acting in the radial direction stamp is again that the working surface of the punch acts mainly in the radial direction.
- the punch can be moved predominantly in the radial direction. However, it can also serve as a stop, which avoids the further growth of the bulge in the radial direction.
- a stop acting in the radial direction avoids the further growth of the bulge as a result of a pressing process in which the pressing tools act predominantly in the circumferential direction and thus displace the material of the bulge in the redial direction.
- the acting in the radial direction punch thus serves in this case as a stop for the displaced material of the bulge.
- the acting in the radial direction stop or punch can also structurally with at least one of
