Description

The invention relates to a packaging suitable as a needle receiving device, with the several needles in an orderly form can be kept ready for use.

Needle receiving devices and needle packages of various types are known. For example, the DE-PS 258019 an auxiliary device for knitting machines for easy replacement of needles. The auxiliary device includes two rails, which are clamped together by means of a clamp. Between the rails, the needles are to be taken either at their rear or their front hook-side end, wherein they are clamped between the rails.

Furthermore, from the DE-PS 260953 a clamping device with two strips known between which needles are clamped parallel to each other and spaced from each other. This clamping device also serves as an auxiliary device for easy replacement of needles.

The US-PS 2771187 shows a letter box for sewing needles with an envelope in which a receiving pocket for needles is formed. The needles are pushed into the receiving pocket, after which the envelope is closed.

It is an object of the invention to provide a holding device, in particular for needles for knitting machines, which is suitable as a needle package. This object is achieved with the holding device according to claim 1:

The holding device according to the invention has a flat needle carrier section and a clamping lip arranged opposite to it. The clamping lip is bent in the direction of the needle carrier portion and may be biased towards the needle carrier portion. The clamping lip is adapted to span one end of a needle therebetween and to clamp and thereby hold the needle against the needle carrier portion. It can be arranged side by side in this holding device, if necessary, many needles side by side, the clamping lip then holds the needles stretched against the needle carrier section. The clamping lip and the needle carrier section are preferably in direct direct contact with the needles.

An advantage of the concept of the holding device according to the invention is that unlike needle bundling by means of elastic cords, O-rings, wires, rubber ring, etc. virtually any size large groups of needles can be accommodated in a needle receiving device. After taking some Needles, the remaining held by the needle receiving device needles remain organized as an association.

Unlike the packaging of needles or other elongated knitting tools on wires or nylon cords, the knitting tools or needles to be accommodated by the needle receiving device of the present invention need not have separate designated openings.

In the case of the needle receiving device according to the invention, the clamping lip is bent in the direction of the needle carrier section. In this case, the distance between the underside of the clamping lip and the upper side of the needle carrier section is smaller than the height of the male knitting tool to be accommodated. As a result, the recorded knitting tools are biased against the needle carrier section with such a force that the accommodated needles are automatically held in position. Also, the clamping lip preferably has some elasticity with respect to a direction transverse to the longitudinal direction of the needles so as to uniformly press all adjacent needles against the needle carrier portion, regardless of any smaller tolerances.

The needles can be held in the holding device without connection to each other. Only the clamping lip holds the needles together as a block. However, it is also possible to additionally secure the needles with each other. For example, the needles can be interconnected by fixing lacquer or by mechanical means, such as a rubber cord. If the needles each have a suitable opening and these openings of the needles are aligned with each other, a direct rubber cord can be drawn through these openings. When released, it will stretch longitudinally together and expands in the radial direction. She can clamp the needles sitting on her, which then form a block held together. Such a block can be reliably picked up and stored by the holding device according to the invention.

It may be provided on the holding device except the clamping lip further means for holding or fixing the needles. For example, the needle carrier section may include structures, e.g. in the form of angled edges, which prevent lateral slippage of the held needles. The needles can also be held down by means of an elastic band or a suitable band.

The clamping lip spans the needles mounted by the holding device. Preferably, the clamping lip is bent so far at its free end following a pressure or contact point with the needle that a trouble-free insertion of the male needles is possible. In the longitudinal direction of the needle, the clamping lip is preferably at least so long that it completely spans the stitch-forming region of the inserted needle, so that the stitch-forming region is received by the receiving space formed in the holding device. While the needles rest with their needle back on the flat needle carrier section over a greater length or over the entire length, the clamping lip presses only at one point on each needle.

In a preferred embodiment, the receiving device consists of at least two parts in the form of a Nadelhaltespange and connected to the Nadelhaltespange support plate. The clamping lip is formed as part of the Nadelhaltespange. While the Nadelhaltespange example. Off Plastic may be formed, the support plate is preferably made of another material, such as. Cardboard, also plastic, another plastic. In addition, the Nadelhaltespange and the support plate may be formed of the same or different metals. Preferably, the Nadelhaltespange and the support plate with each other by riveting, caulking, pressing, gluing, joining or other measures permanently or releasably connected to each other.

If the carrier plate itself is absorbent or provided with an absorbent covering, for example a felt covering or another textile covering, it can form a storage means for preservatives or treatment substances. This opens up the possibility in the needle receiving means of substances such as corrosion inhibitors, e.g. suitable oil, which is then gradually released to the needles to protect them. This enables the world-wide delivery of needles of the highest quality and long-term storage even under adverse environmental conditions.

Preferably, a slot is provided for connecting the carrier plate with the Nadelhaltespange in one of the legs of the Nadelhaltespange, in which the carrier plate is inserted. The slot may be bounded by two equally long or unequal length walls. Preferably, a slope or ramp is formed on a front edge of the knitting tools or needles facing wall, which facilitates the insertion of the needles. If the lower wall remote from the needles is longer than the upper wall, the needles, on the one hand, are in contact with the carrier plate over a large length and, on the other hand, the carrier plate is stiffened by the lower wall.

To facilitate insertion of the carrier plate into the slot, one of the two walls delimiting the slot at the slot mouth may be chamfered, rounded or tapered.

It is also considered advantageous to provide positioning means for the carrier plate in the slot. For example, ribs may be provided in the slot between which an edge of the inserted carrier plate is held. In addition, at the ends of the slot defining walls, projections or ribs may be formed, which hold or clamp the carrier plate between each other. This has the advantage that the support plate is clamped or stored clamped at two spaced-apart defined strip or line-shaped areas. This is for the precise alignment of the carrier plate and the Nadelhaltespange each other. If necessary, the slot may include a binder in the form of an adhesive that cohesively bonds the carrier plate to the needle retaining clip.

The support plate can not only be held in the slot materially. It is also possible to connect the carrier plate with the Nadelhaltespange positive. This is, for example, possible by means of more or less sharp-edged ribs, which are impressed on one or two sides into the carrier plate and which are connected to the needle-holding clasp.

In a particularly comfortable to be operated and storage particularly sensitive knitting tools or needles suitable needle receiving device of the needle holding clasp is associated with an actuator. The actuating device is preferably adapted to move the clamping lip away from the carrier plate upon actuation, so that the needles can be slid without problems between the clamping lip and the carrier plate. When inserting or removing, the needles do not have to apply the force required to open the clamping lip. As an actuating device are, for example, projections which extend beyond the elastic region which connects the clamping lip with the support plate, approximately parallel or at an acute angle to each other.

FIG. 1 illustrates a needle holding device 1 with needles 2, which are received in the needle holding device 1. The needle holder 1 serves, for example, as a needle package for needle shipping and for storing and keeping ready the needles. It can also only form part of a needle package. The needle holding device 1 has a receiving device 3, to which a flat needle carrier section 4 and a clamping lip 5 arranged opposite thereto belong. The flat, preferably flat and in plan view rectangular needle carrier section 4 and the clamping lip 5 can be interconnected by a e.g. be connected arcuate spring portion 6. This biases the clamping lip 5 against the needle carrier section 4 and keeps the clamping lip 5 simultaneously pivotable. It forms a spring hinge. The clamping lip 5 and the needle carrier portion 4 may be integrally connected to each other via the spring portion 6. In the simplest case, the needle carrier section 4, the clamping lip 5 and the spring section 6 of a suitable relatively stiff, but somewhat flexible material such as. Plastic.

While the needle carrier section 4 is largely planar, the clamping lip 5 preferably has an edge 7 bent away from the needle carrier section. Thus, the clamping lip 5, starting from the spring portion 6, initially approaches at an acute angle to the needle carrier section 4 up to a contact point 8, where it touches the needles 2 and then again runs to form an insertion funnel at an acute angle to the needle carrier section. 4 from the contact point 8 and the needle carrier portion 4 away. In this way, the clamping lip 5 encloses an inner space 9 into which the needles 2 protrude with their stitch-forming portions 10. These include the hooks of the needles, the needle breast and a part of the needle shaft. The interior 9 has a corresponding length L, which is defined by the length of the clamping lip 5, ie the distance of the contact point 8 of the spring portion 6. The clamping lip 5 is shorter than the shanks 11 of the needles 2, so that the other adjoining a step parts 12 of the needle body and their feet 13 are outside the interior 9 and lie on the needle carrier section 4.

As illustrated in Figure 1, the needles 2 are pressed firmly against the needle carrier section 4 by the clamping action of the clamping lip 5 and thereby held as a block. A formed by the stitch forming part 10 of each needle 2 end 14 is held in the interior 9 while the remaining parts 12 of all needles 2 remain outside of this interior 9. The holder of the needles 2 is thus effected only by the clamping action of the clamping lip 5 on the needle shaft between the stitch-forming part and a subsequent to the shaft stage. To support the fixation of the needles 2, the needle carrier portion 4 may be such that the friction coefficient between the needle bottom (needle back) and the needle carrier portion 4 is as high as possible. This can be achieved by selecting suitable materials of the needle carrier section 4, e.g. in the form of rough cardboard or by a suitable coating. An increase in friction can also be achieved by structuring in the form of small elevations, webs or nubs. This ensures that the needles 2 can hardly move laterally on the support plate 4.

As FIG. 2 illustrates, additional means 15 for fixing the needles 2 to the needle carrier section 4 can be provided. Such means 15 may, for example, in the form of a or several bands 16 may be formed, which overlap the needles 2 transversely and additionally hold. Such banderoles 16 can also serve as a tamper-evident closure. They may, as shown, be arranged at the free end of the needles 2 or between their feet 13. It is then necessary to remove them before needles 2 can be removed. If the bands 16 made of paper or plastic, they must be torn or cut to it. Alternatively, if it is possible to dispense with a tamper-evident closure, it is possible to provide resealable bands 16. Otherwise applies to the embodiment of Figure 2 on the basis of the introduced reference numerals corresponding to the description of FIG.

A further modification is shown in FIG. 3. The previous description of FIG. 1 or alternatively of FIG. 2 applies correspondingly to FIG. 3. In addition, one or more projections are formed on the needle carrier section 4, for example in the form of an angled edge 17 oriented parallel to the needles 2. At the opposite longitudinal edge of the needle carrier section 4 can also be provided an angled in Figure 3, but not further illustrated edge. The edge 17 can be surrounded by a band, a rubber band or another packaging, for example. In the form of a plastic bag, a Kunststoffschrumpfschlauchs or the like.

A further modification of the needle-holding device 1 is shown in FIG. Based on the embodiment of Figure 1 or the embodiments of Figure 3 or 2, the needles 2 can be held together by a rubber band 18 that spans the needle carrier section 4 and the needles 2.

Further details of the described so far embodiments of the needle holder device 1 will be apparent from Figures 5 and 6. As can be seen, the clamping lip 5 may be formed substantially flat or bent at an angle to the needles 2 extending bending line 44. In both cases, the edge 7 terminates in an edge 19 whose distance h ₁ to the needle carrier section 4, when no needle is inserted into the interior 9, is greater than the height h _{2 of} the hook top of a hook 20 one with its needle back on the needle carrier section The bias of the spring portion 6 can be so dimensioned that the clamping lip 5 rests with the contact point 8 on the needle carrier section 4 or defines a narrow gap with this. In any case, this gap is narrower than the height of the shaft 11 of the needle 2 to be stored. In addition, the possible spring stroke of the spring section 6 is greater than the height h ₂ .

Operation of the needle holder 1

For insertion into the needle-holding device 1, the needles 2, as illustrated in Figure 6, pushed under the edge 7. They slide into the interior 9. The contact point 8 moves over the hook 20 and the stitch-forming portion 10 of each needle 2. Finally, the hooks 20 of the needles and possibly existing tongues 21 (Figure 6) in the interior 9, where they do not experience further contact with other parts. The contact point 8 maintains a safe distance to the hook 20 and the tongue 21 a. The clamping lip thus engages over the stitch-forming part 10 of each needle 2.

Further details and embodiments of the invention are described below. These embodiments can be found in all the embodiments described above. According to FIG. 7, the needle carrier section 4 and the clamping lip 5, together with the spring section 6, can be formed as separate parts, which consist of identical or different materials and are connected to one another. For example, the receiving device 3 may be formed by a needle holding clip 22 and a needle carrier plate 23. The carrier plate 23 is, for example, a carton while the needle holding clip 22 is e.g. made of plastic. The Nadelhaltespange 22 is an element consisting of three parts. The clamping lip 5 is connected via the spring portion 6 with the leg 24 which carries the support plate 23. The support plate 23 is connected to the leg 24 via a connecting means 25. This is done e.g. an adhesive joint, in which the support plate 23 is bonded over a large area with the leg 24. The leg 24 is preferably longer than the clamping lip 5. With the contact point 8, the clamping lip 5 can press the support plate 23 against the leg 24.

As shown in FIGS. 8 to 11, the connecting means 25 may also comprise a slot 26 formed in the leg 24. A first related embodiment illustrated in Figure 8. The slot 26 is oriented parallel to the support plate 23 and bounded by two walls 27, 28. These are arranged parallel to one another and parallel to the carrier plate 23. The support plate 23 is inserted in the slot 26 and connected to the Nadelhaltespange 22. This can serve as a bonding agent adhesive, for example, connects the wall 27 with the support plate 23. Also, adhesive may be provided in the slot 26 to assist in the connection.

Furthermore, at least in a preferred embodiment, the wall 28 is provided at its edge adjacent to the slot 26 with a slope 29 or ramp surface. This forms a gently rising transition from the support plate 23 to the interior 9 facing surface of the wall 28. The slope 29 facilitates the insertion of needles in the interior. 9

It is also possible to make the upper wall 28 longer than the outer wall 27, as FIG. 9 shows. The bevel 29 in turn facilitates the insertion of needles under the edge 7, which, as in all the embodiments described above, with the support plate 23 and the wall 28 (Figure 9 and 11) defines an insertion funnel 30. The needle receiving device 3 is in turn formed by the clamping lip 5 and the support plate 23.

Preferably, in all embodiments, according to Figure 7, 8 or 9, but in particular in the embodiment of Figure 9, the lower wall 27 may be provided on its slot inside with a run to the slot edge slope 31. This facilitates the insertion of the support plate 23 in the slot 26. The connection between the support plate 23 and leg 24 can turn by a connecting means 25, for. Be made adhesive.

As FIG. 10 illustrates, the leg 24 may also be shorter than the clamping lip 5. This is especially true when the carrier plate 23 is relatively stiff. Both walls 27, 28 may be provided with the previously described bevels 29, 31, on the one hand the insertion of the needles in the interior 9 and on the other hand, the insertion of the support plate 23 in the slot 26 to facilitate.

It can, as Figure 11 shows, both walls 27, 28 be longer than the clamping lip 5 and thus protrude beyond the contact point 8 also. Again, the slopes 29, 31 are present.

Further possibilities for the connection between the carrier plate 23 and the leg 24 are illustrated in FIGS. 12 and 13. The walls 27, 28 of equal length and rounded at their edges enclose an inner space 32 whose width, which is perpendicular to the carrier plate 23, is greater than that Thickness of the carrier plate 23. At the free end of the walls 27, 28 rib-like projections 33, 34 are formed. At the bottom of the interior 32 also rib-like projections 35, 36 are formed, which define a distance 37 between each other. This corresponds approximately to the thickness of the support plate 23 or is slightly smaller than the same.

The support plate 23 may, as Figure 13 shows, with corresponding, the projections 33, 34 associated depressions, be provided. If the carrier plate 23 is somewhat yielding, these depressions can also be shaped under the action of the force formed by the projections 33, 34. The support plate 23 is thus held in two linear zones which are defined by positioning means, on the one hand by the projections 33, 34 and on the other by the elevations 35, 36. The support plate 23 may be kept very precise in this way, the interior 32 may be filled with adhesive 38, moreover, to secure the support plate 23 to the leg 24.

Further modifications are shown in FIGS. 14 and 15. As FIG. 14 illustrates in conjunction with FIG. 15, starting from the embodiment according to FIG. 7, a rib 39 can be formed on the leg 24 at a point preferably opposite the contact point 8. This may be triangular in cross section and have an edge to be pointed on the leg 5. This is expressed in the example. From cardboard existing carrier plate 23 and thus secures them in the longitudinal direction. For further connection between the support plate 23 and the leg 24 in turn adhesive 40 may be provided.

As will be seen later from FIG. 14, the needle-holding clasp 22 may be provided with an actuating device 41 in order to open and close the clamping lip 5 in a controlled manner. The actuating device 41 is formed, for example, by extensions 42, 43, which adjoin the leg 24 or the clamping lip 5 and extend beyond the spring portion 6 forming a hinge. The extensions 42, 43 may extend over the entire width of the Nadelhaltespange 22, which is oriented transversely to the needles 2 and in Figure 14 perpendicular to the plane. Due to the rigid connection between the extension 42 and the clamping lip 5 and the rigid connection between the extension 43 and the leg 24 of the leg 5 is moved away from the support plate 23 when the two extensions 42, 43, for example, be compressed by hand. This makes it possible to introduce needles into the interior 9 without the contact point 8 having to touch the hook and the tongue. In addition, needles can be removed from the interior 9 without the hooks have to push out the clamping lip 5 from its clamping position.

The support plate 23 may be formed of an absorbent material or be provided with such a whole or partial area. This applies to all embodiments described above.

A needle holding device 1, which is particularly suitable as a packaging, has a flat needle carrier section 4 and a subsequent section, which has a clamping lip 5, which is resiliently tensioned against the needle carrier section 4. The clamping lip 5 engages over the stitch-forming portions 10 of needles 2, which are held adjacent to each other adjacent to each other on the needle carrier section 4. The resilient clamping lip 5 allows insertion and removal of one, several or all needles 2.
