Abstract
Description
- The present invention relates to all-steel card clothing for use on drums in carding machines.
- All-steel card clothing is used in various areas of processing textile fibers. The present invention relates to a card clothing wire for use on rollers in fiber processing operations, in particular on drums in carding machines. When used on rollers, the card clothing wire is coiled in the form of sawtooth all-steel card clothing and wound close together or in grooves on the roller. The usual forms of sawtooth all-steel card clothing are defined in the International Standard ISO 5234 (2004). According to this standard, all-steel card clothing is characterized by, among other things, the working angle α, their back angle γ, their tooth pitch p and tooth depth h6, the total height h1 of the wire, the base width b1, and the blade width b3 at the tip. The working angle is the angle between the front face of a tooth and the line perpendicular to the base of the wire, wherein the front face represents the front tooth face as seen in the direction of movement. If the front angle α is 0°, then the front face is at a right angle to it, i.e., is aligned vertically in relation to the wire base. The back angle γ in the present description is the angle between the back face and the line perpendicular to the wire base, wherein the back face represents the back tooth face as seen in the direction of movement. If the back angle γ is 0°, then the back face is perpendicular, i.e., vertical to the wire base.
- In the fiber processing operations, such as opening and cleaning fibers or fiber flocks, high demands are made of the all-steel card clothing, which is used with respect to efficient parallelization of the fibers in the carding operation in particular. The condition for this is guidance of the fibers as close to the surface of the card clothing as possible. The transfer of fiber from the first roller to another roller is also extremely important. In the case of a carding machine, this is true in particular of the all-steel card clothing applied to the drum. These determine essentially the fiber transfer from the feed roller to the drum and the fiber transfer from the drum to the recipient, as well as the fiber guidance in the carding operation.
- For example, WO 2013/072136 A1 is known from the prior art, and discloses an all-steel card clothing for the drum of a carding machine. The steel card clothing has teeth with the tips of the teeth pointing in the working direction and with the backs of the teeth following the tips of the teeth, wherein the backs of the teeth are provided with at least one elevation. The fibers are to be held at the surface by the backs of the teeth, which are provided with an elevation. One disadvantage of the embodiment disclosed here is that the individual tooth is lengthened due to the tooth back, which in turn results in an increase in the tooth pitch and, therefore, also the tooth density on the drum is reduced and the possible fiber transfer is also reduced.
- The object of the invention is to create a card clothing wire, which will permit fiber guidance on the surface of the card clothing with an improved fiber transfer to the drum and from the drum to the downstream roller. Additional objects and advantages of the invention will be set forth in part in the following description, or may be obvious from the description, or may be learned through practice of the invention.
- The objects are achieved by the features of the invention described and claimed herein.
- To achieve this object, a card clothing wire is proposed for use on drums in carding machines, wherein the card clothing wire consists of a base and a blade having a total height h1 of the wire of 1.5 mm to 5.0 mm. The total height h1 of the wire is preferably 1.8 mm to 3.0 mm, especially preferably 2.0 mm. The blade is furnished with teeth having a first tooth tip with a tooth depth h6 of 0.3 mm to 1.0 mm, the tooth depth h6 preferably amounting to 0.3 mm to 0.6 mm, especially preferably 0.4 mm. The card clothing wire has a tooth pitch p of 1.4 mm to 2.5 mm, the tooth pitch p preferably amounting to 1.6 mm to 2.0 mm, especially preferably 1.81 mm (corresponding to 14 tips per inch). The teeth have a back face with a back angle and a tooth front face with a working angle. The back angle amounts to 50 to 80 angle degrees, preferably 60 to 70 angle degrees, especially 65 angle degrees. A second tooth tip is formed on the back face of the tooth at a tip spacing from the first tooth tip such that the second tooth tip has a back face with a back angle and the back angle of the second tooth tip amounts to 50 to 80 angle degrees, preferably 50 to 70 angle degrees, especially preferably 65 angle degrees.
- Due to this geometry of the teeth with two tooth tips, wherein the second tooth tip is formed on the back face of the first tooth tip, the fiber transfer, in particular the takeover of fiber from a previous roller, is facilitated. In addition, the two tooth tips per tooth advantageously have an effect on the fiber transport of the fibers through the card clothing and yield a considerable improvement in carding. The second tooth tip not only produces an increased fiber transfer, but is also responsible for the fact that the fibers are held on the surface of the card clothing.
- A tooth back face, which extends from the tip of the tooth to the base of the tooth with conventional all-steel card clothing, is interrupted in the proposed embodiment by a second tooth tip. A tooth intermediate space is formed between the first tooth tip and the second tooth tip, where the tooth back of the first tooth tip is connected to the second tooth tip by a concave surface segment. The tip spacing between the first tooth tip and the second tooth tip is advantageously 10% to 50% of the tooth pitch p. This achieves the result that the second tooth tip is also actively involved in the process of fiber transport and contributes to an improved transfer of fiber.
- Preferably, the height of the tooth intermediate space between the first tooth tip and the second tooth tip amounts to 10% to 50% of the tooth depth (h6). Therefore the fibers are at least partially prevented from falling into the card clothing and the carding operation is improved. The minimum height of this intermediate space is necessary to form the second tooth tip because the second tooth tip manifests only an effect in improving the fiber transfer when its working angle is positive, i.e., greater than 0. However, a negative working angle is also conceivable, which results in at least an improvement in the carding operation due to the guidance of the fibers at the surface of the card clothing.
- In addition, it is advantageous if the total height of the wire (h1) is the same at the first tooth tip and at the second tooth tip. The tooth tips are subject to wear and are worn down over time. The card clothing is reground periodically for this reason, so the lifetime can be increased. Now if both tooth tips are the same height, this yields the possibility of detecting the first and second tooth tips in a grinding operation. The card clothing thereby also retains its advantageous characteristic even after multiple grinding operations.
- The first tooth tip has a blade width b3 of 0.04 mm to 0.08 mm. The blade width b3 of the second tooth tip is advantageously of the same size. This circumstance also contributes to the fact that the second tooth tip manifests approximately the same effect as the first tooth tip. This also avoids having one of the tooth tips cover the other one. The working angle of the first tooth tip advantageously amounts to 30 to 50 angle degrees. A larger working angle increases the aggressiveness of the card clothing. The working angle is determined by the production height and the fiber material to be processed. The working angle of the second tooth tip in particular is preferably the same size as the working angle of the first tooth tip.
- The card clothing wire is embodied as an all-steel card clothing wire and may be designed with a normal locked or chained base to enable the card clothing wire to also be applied to a smooth roller or in grooves.
- The card clothing wire is suitable in particular for mounted rollers of carding machines such as the drums, for example. When using the card clothing wire on a drum, it is applied in a spiral form.
- The invention is explained in greater detail below on the basis of exemplary embodiments and is illustrated in greater detail by the drawings.

FIG. 1 shows a schematic diagram of a view of a specific embodiment of a card clothing wire. -
FIG. 2 shows a schematic diagram of a cross section of the card clothing wire according toFIG. 1 . -
FIG. 3 shows a schematic diagram of a view of another specific embodiment of a card clothing wire. - Reference will now be made to embodiments of the invention, one or more examples of which are shown in the drawings. Each embodiment is provided by way of explanation of the invention, and not as a limitation of the invention. For example features illustrated or described as part of one embodiment can be combined with another embodiment to yield still another embodiment.
